Advanced Automotive Battery Conference: Running out of road?

Tesla-Model_S_2013_1600x1200_wallpaper_02

The Editor bring a fresh pair of ears and eyes to the 14th Advanced Automotive Battery Conference. Is the industry sticking to the roadmap or has it taken a detour? This article was first published in the Spring 2014 edition of Batteries & Energy Storage Technology.

This author recently saw a presentation by brand marketing guru Peter Economides, who worked on Apple’s relaunch following the return of Steve Jobs in 1997. Economides’ key message was that to succeed, you have to get the customers to do your work for you.

In other words, word of mouth. The early adopters and influential types buy something, like it, and tell their friends. The friends buy it, who tell their friends and so it goes on. Granny will never buy it, by the way, no matter what it is.

Economides cites Better Place, which hired him in its dying days in late 2012, as a classic example of how not to do it. He showed a Better Place commercial featuring a young man telling us why he drives an electric car. In a word, it boiled down to domestitude.

He drives his EV because “She” is for people who want to save the polar bear. The visuals of a similarly aged woman makes it clear that “She” also refers to his lover, the woman who he hopes wants to marry him and have his babies.

Ultimately, the advert (and Better Place) was, in effect, trying to sell electric vehicles – a Herculean task and probably doomed to failure.

Trying to convince someone to spend upwards of $50,000 on a car in an effort to settle down to domestic bliss with their sexy, tree-hugging partner was a bum steer, said Economides. It wasn’t cool enough to influence the influencers; it was trying too hard to be cool while simultaneously trying to appeal to everyman.

Tesla is different. Flying in the face of the mainstream, Elon Musk’s outfit has switched its marketing focus on to the sexiness of the car rather than the driver. The message is rapid acceleration = sexy. Saving polar bears = not sexy.

The drawback, of course, is the cost. And what is the main cost? The batteries!

Tesla, which did not attend AABC, was something of an elephant of the room. It remains an outlier. Who could have predicted when AABC started in 1999 that a nerdy billionaire would cram 7,000 laptop cells into a supercar and thus turn the concept of away from environmental masturbation to a penis-extension supercar?

Most of the presentations were by mass-market OEMs, but it would have been very interesting if Tesla had been there too, 18650s or not. Will Tesla’s ‘cheap’ EV be able to weigh in at circa $40,000 as publicized? Besides, what will $40,000 get you? 40 miles range? 60 miles? 100 miles? Seats included? Doors too? We’ll have to wait and see.

Detour from the roadmap

AABC is quite a glitzy show, sleekly managed in an impossible-to-get-lost kind of way. There are concerns that AABC is not quite the force it once was. Perhaps this is true. But if it is, it’s more due to the industry taking a detour from the EV roadmap.

All the projections for EV take-up are well short of expectations. When AABC first came into being in 1999, peak oil was a real concern and future decisions about auto electrics and the contribution it could make to vehicle performance and emissions reductions were up in the air.  Shale oil and gas has seen that off for the time being.

In Europe, emissions reduction targets have been delayed and/or watered down. Will the US follow suit? The final decision to adopt the federally mandated fleet average of 54.5 mpg by 2025 will be taken by Congress in 2017.

If the Republicans get in again, this ambitious target could also be seen off as an ‘attack on personal liberty’ or some such. Perhaps the answer to the car industry’s emissions headaches lay in paying off Jeb Bush, Chris Christie or whichever character ends up winning the Republican nomination?

Even if the EV industry hasn’t quite taken off as hoped, AABC remains a conference with clout on the cultural calendar, attracting C-level speakers and most of the right companies. But it is noteworthy AABC will hold its first conference in Asia – in Japan’s Kyoto – in May.

The Japanese may have already won the battery war. Toyota, Panasonic et al are years ahead in both lithium batteries and EVs, while Samsung and LG Chem have caught them up in terms of lithium battery sales. Asia, perhaps more than ever, seems the natural place for an advanced automotive battery show.

To this end, the author was struck by a presentation by ARPA-E’s Ilan Gur, who spoke about an AMPED (Advanced Management and Protection of Energy Storage Devices) project for the US DoE.

Gur repeatedly boasted about how ARPA-E was the “skunkworks” of the US battery industry, but this particular project seemed pretty conservative. Gur started off by saying next-generation technologies typically took 50-70 years to become standard issue, the implication being they shouldn’t bother.

But surely the job of ARPA-E, so often compared to the Pentagon’s DARPA, is to reduce this (extremely lengthy) timeline? Instead, AMPED is dedicated to getting more out of existing technology: what it calls “removing the blinkers” from lithium-ion.

This, it is envisaged, would achieved by developing ‘smart cell’ battery packs, with individual cell-level active monitoring and control via sensors. A ‘smart cell’ system would reduce the physical capacity of battery packs by 20-30% by mitigating the need for other power electronics in the vehicle.

As this is a system-level approach, the development of ‘smart cell’ EV battery packs requires the input of 10-15 different development teams, so there is little chance of manufacturers developing such a system. Which is a big reason why ARPA-E is funding it.

But is this really something which should concern ARPA-E? Is this going to have the Japanese quivering in their boots?

It is also highly noteworthy that both AABC Europe and AABC 2015 will both include “two to three sessions” concerning stationary battery applications. This seems a sign AABC is either running out of automotive ideas or delegates, or both.

Attendees were down roughly 100 on 2013. Is this merely due to being held in Atlanta rather than Florida, as initially planned? Next year’s AABC will be in Grand Rapids, Michigan, which may well be picturesque but is not exactly a metropolis.

Commercial breaks

AABC seemed rather like US television: commercials punctuated by the actual programmes you tuned in to see.

William ‘Freedom’ Wallace of General Motors kicked things off with a commercial for the Chevy Volt, aka the Opel Ampera in Europe. It remains the United States’ best-selling PHEV (40% of sales were in California) at 23,000 units, although sales dropped by c.350 in 2013.

GM draws encouragement from the widening socio-economic profile of buyers of the Volt. The average income of a Volt owner has fallen from $150 000 in 2011 to $75 000.

GM’s sample of 500 Volt users found they drive an average 27 all-electric miles per day, leading to an 81% reduction in gas. A concern for GM is that US power utilities are looking to recoup the cost of EV charging infrastructure – the days of freebies are coming to an end.

GM said ‘fun to drive’ was the main reason to buy a Volt. It was only when your author brought up the question of how much longer will Volts be eligible to drive in California’s car pool lanes – its days are numbered – were reasons other than the Volt’s ‘greatness’ proffered.

Michael Lord of Toyota wasted no time in saying the Prius is better than the Volt and the Leaf, but served up a few useful nuggets, such as EV sales total 10,000 a month in the US, with an 84% jump in 2013 overall. xEV sales have risen 900% since 2005 and with BMW, Daimler, Hyundai, Kia, Mazda and Volkswagen coming to the party before 2018, sales are only going one way, if not as quickly as anticipated.

As usual, Avicenne Energy’s Christophe Pillot won the ‘Most Beautiful Slides’ award at AABC 15. Even if EV sales are not spectacular, a very small EV market in the automotive world will still represent a huge market for batteries.

The respected Frenchman forecasts 10% annual growth of lithium sales until 2025, with 15% annual growth for ‘new’ lithium applications such as UPS, telecoms, forklift, medical, residential and grid energy storage.

As an aside, Pillot mentioned the cost of 18650s falling from $1.50/Wh in 2000 to just $0.17/Wh now. Expect further substantial price decreases in the coming years.

The great 48V debate

The debate about whether the auto industry should introduce 48V vehicles to cope with the growing power demands of cars continues apace. Stephen Kim of SK Continental gave the by now obligatory ‘48V is inevitable, it’s happening, please buy our kit’ spiel.

Having developed a 48V NMC pack, SK Continental is in a slightly smug position if it does take off but overall this author was not particularly convinced about its apparent low cost/inevitability.

Real-world 48V driving conditions may see a 25% in CO2 reductions against only 10% for test cycles, but real-world conditions do not matter when this is driven by regulation. Unless, of course, the regulations change…

SK Continental expects 9% of the global market will comprise mild hybrids, of which 21% will be sold in the EU, 15% in the US and just 1% in Asia. Hmmmm.

Dr Anderman then went about obliterating the arguments for 48V, starting off with a reminder of just what a flop 42V was ten years ago, with more or less only the 42V versions of the Ford Escape and GM Silverado seeing the light of day. The implication was clear: 48V is the new 42V.

Dr A raised more questions than he answered. The costs of lithium 48V were a predicted $1000/kW, more than a full hybrid EV. Can OEMs deliver a cost-effective 48V system while  keeping within the 60V safe over-voltage limits? Will mass production of 48V bring down costs enough before 2020?

Is 12-15 kW at 48V really much less expensive than at 110V for a plug-in hybrid? And, that being the case, why would anyone buy a mild hybrid and not a plug-in hybrid?

The plain truth is mild hybrids are not sexy enough and even if it costs $1 500 for a 15% fuel efficiency gain, the stats show customers are more willing to pay $3 500 for 35% fuel efficiency improvementas it offers the prospect of a purer hybrid experience. Indeed, mild hybrid sales are expected to fall over the next three years.

Looking to what’s happening in Japan, Dr A notes Honda has replaced its Fit mild hybrid and is offering two new powertrains: the P2 strong hybrid and the Micro-2 hybrid with ultracap pack.

While Honda and GM are likely to continue shrinking their moderate/mild hybrid offerings, European car makers are developing 48V mild hybrids for Model Year 2016 and beyond.

But at current cost levels, these can only be justified for high-end cars. Automakers have to absorb much of the extra cost and the positive business case is probably still beyond 2020.

The debate was taken on by the car manufacturers, which are looking to 12V stop-start as far as possible to meet emissions regulations in the mid-2020s. Ford’s Daniel Kok said the business case for 48V was a challenge and may well not bother with it.

Compared to Europe with 25% of new sales, stop-start cars are relatively small phenomenon in the US. But if there is one projection on which you may wish to bet your house, it is the adoption of good old lead-acid 12V stop-start in the US will soar.

Unlike hybrids there are common standards for stop-start for almost all processes, and it is cheap, low-hanging fruit for emissions reductions. The question is: will 12V lead-acid stop-start be enough in the US?

Probably not; Ford, for example, needs to reduce emissions by 4% a year. Chrysler, meanwhile, was sweating cups about its gas-guzzling pick-up trucks ruining their future average fleet emissions.

Besides, lead-acid stop-start doesn’t always work as it should and this makes customers uncomfortable; Ford says 30% of its customers deselect stop-start. So, Ford is looking at 12V lithium-ion stop-start not only as a fix to the increased energy demands of cars, whose cabins are rapidly becoming entertainment centres, but also to harness regen power.

Kok says 12V lithium-ion is a very feasible option but the costs need to drop 30-50% to get there. LG Chem agreed, seeing 12V lithium coming down the track before 48V.

Jeff Kessen of A123 Systems says the 11.5kg weight reduction and 3-5% fuel economy saving due to increased charge acceptance puts the value of a 12V li-ion battery system at the $200 mark compared to $78 for 70Ah AGM lead-acid system.

In cash terms, the pack costs of a VRLA lead-acid battery are roughly $115 versus $600 for an equivalent lithium iron phosphate pack. This $500 cost premium could drop to $300 by the end of the decade. Although even then it will still be more than twice as expensive as VRLA, this does seem as a relatively cheap way to meet emissions reduction targets.

A123 says there is a positive business case for 12V lithium now, but where are the sales? The cost of lithium remains the biggest hurdle, while there is also the ‘hot button’ issue of cold cranking temperatures.

12V lithium-ion could potentially offer 4 kW compared to 10-15 kW for 48V. In effect this would be a micro-mini hybrid; not quite up to 48V levels, but offering significant fuel economy and emissions reductions on existing 12V stop-start. 

Bright lights, big city

The final day was a little PR heavy and only 90 brave soldiers managed to stay the course for the full five days of AABC. Yet one of the most interesting sessions was saved for last – on charging infrastructure.

The key messages was using the public purse won’t be enough to pay for chargers – it needs capitalism – and, like the Kevin Costner movie ‘Field of Dreams’, build it and they will come.

For Chargepoint, which is doing a roaring trade in installing EV equipment for private parking lots in the US, capitalism is working. So much so, in fact, that the wife of Chargepoint’s CEO Richard Lowenthal has a housekeeping allowance which stretches to buying him a Tesla S for Christmas.

Lowenthal explained how free electricity for EV charging is worth $550 per employee per year to Google as a tool to retain employees. In contrast, Microsoft makes a profit from employee charging.

The ‘build it and they will come’ model may well work in the US, where many businesses have their own parking lots in which to offer subsidized charging. In countries where there is not a mall on every corner and citizens make use of their legs to get around, however, public charging may be needed for EVs to take off as hoped.

This remains a very tough nut to crack. EVs are being sold as city cars, but many city dwellers live in apartments without practical access to charging. Furthermore, with space in cities at a premium, installing charging infrastructure may mean retrofits.

Mark Duvall of EPRI put the cost of retrofitting car parks at $100,000 for a DC charger. Who is going to pay for that? In this case, capitalism won’t be enough; it’ll need grants, subsidies, mandates etc.

An elephant in the room 

One of the main takeaways of the 14th Advanced Automotive Battery Conference was the future cost of electric vehicles versus their ever more efficient internal combustion engine rivals over the coming decades.

Next-generation ICEs, which may feature turbo-charged dedicated EGR (exhaust gas recirculation) engines, will match or even exceed the fuel economy of hybrid cars. For a Toyota Camry, the engine efficiency rise from 36.3% to 38.4% in 2030 and 42% in 2050 will translate into a fuel economy rate of 32.2 mpg today rising to 65.6 mpg to 88.5 mpg respectively.

The message is that one of the strongest arguments to go electric – fuel savings – may not always be so.

Yet for most of the advanced powertrain technologies there is a single point in the future where the costs start to get very similar. John German of the International Council for Clean Transportation had a number of interesting slides that showed the manufacturing costs of ICE, plug-in hybrids, pure EV, and fuel cell cars would converge in the 2040s.

When the manufacturing costs of ICE cars will exceed battery EVs, hybrid EVs, fuel cell cars (if not plug-in hybrids), and the cost of ownership issue will likely disappear. But this may not be for decades.

At the moment the industry is at 80 real-world miles range for a mass-market vehicle, but what happens when we get to 120 miles? The greater range will simplify charging infrastructure.

A lot of the need for convenience charging goes away and the need for public charging infrastructure comes from PHEVs, and they’ll be lots of them. Domestic charging will be sufficient for metropolitan day-to-day charging. Fast charging will take care of the rest.

Dr A sees 120-150 miles real-world range needed for mass-market appeal of EVs. This is someway off at a realistic price point with lithium. Or will Tesla prove everyone wrong?

Utility customer psychology is bad for you

iu cover crop

This article was first published in the March/April 2014 edition of Intelligent Utility magazine

You may think Europeans are more sophisticated than you Americans, meeting our beautiful partners with cheese-slicer cheekbones to sip cappuccinos in an elegant cafe before jumping on a Vespa back to our Georgian townhouses.

Well, it turns out that when it comes to utility customer psychology, we are pretty much the same as our root beer swilling, cowboy boot wearing, deep-fried-bacon-with-everything eating cousins in the US of A.

There are some pertinent universal truths for the utility industry. Customers don’t like you. It’s true. They feel powerless against the mighty utility which almost always holds the whip hand: they decide the price and customers have to stump up. They feel they have no real choice about this; it’s certainly true this is an industry whose participants offer, at base, undifferentiated products. There are no premium electrons or value-range CH4 molecules.

In simple terms, customer behavior in different nations boils down to the level of energy liberalization/deregulation, market mechanisms and how smart are the utilities. In those countries with state-run command and control energy systems, customer behavior simply doesn’t matter as long as supply meets demand.

In sub-Saharan Africa or South Asia, rolling blackouts are often part of everyday life. Most customers in Europe, however, do not even think about energy because it is omnipotent and because it is not expensive enough to really worry about.

In many cases, the command-and-control way of thinking refuses to die, even in nations quite far down the smart track. In North America, utilities are able to create an entire framework for smart grid because they more or less control the entire chain. This means customers are pulled into smart grid on their terms.

In Europe, there is much more potential for an open market, as utilities are more fragmented and they are innovating to compete to have the most attractive offering. This innovation is leading to a change in consumer psychology.

Established thinking says that customers want predictable, flat prices. According to Dr Philip Lewis, who has directly researched over 1 million customers worldwide as CEO of VaasaETT, this remains the case, but is becoming increasingly nuanced.

The question is what the customer means by predictability?

“Price rises, and volatility, make customers want predictability,” said Lewis. “Australia has had several price rises in recent years and as a result it is the most active market in the world. Customers are looking for a way out.”

Often that means fixed-term price contracts, but smart grid means more innovative, variable contracts are increasingly popular. “The old wisdom that customers want predictable pricing is changing,” said Lewis. “What they actually want is a predictably good deal, even if that means volatility. It’s rather like mortgages, you have fixed-rate or variable-rate, and you pick and choose depending on which way the wind is blowing.

“We’re starting to see more and more countries in Europe customers preferring to have more volatile prices in order that they have more transparency. In Norway, 55 percent of customers have spot-tied contracts, in which the supplier charges a commission on a rate tied to the Nordic spot market.”

Conventional wisdom that customers save money through competition, i.e. switching supplier, is also changing. Despite also experiencing sustained, inflation-busting energy price rises, no market has experienced a more dramatic decline in customer activity than Britain, once the most active market in the world.

VaasaETT figures show Britain has fallen from first to twelfth in eight years and from a rate of 21 percent switching per annum to just 11.5 percent in seven years. Shoddy practice, such as mis-sold tariffs and (now outlawed) aggressive door-stop sales, as well as the deliberate complexity and variety of tariffs has bewildered and alienated consumers.

Ultimately, said Lewis, customers want to feel on equal terms with their energy supplier. This is easier said than done, but smart grid technology offers utilities to change customer psychology away from distrust and dislike.

Fundamental to any behavior change is education of the customer. Automation alone is not enough. Customers who participate in automation without education are actually less likely to save energy at off-peak times than if they had no automation at all because they believe automation is doing it all more them, says Lewis. Reduction at peak hours is 40 percent more effective when participants are provided with feedback.

Customers want to feel in control and they have to feel rewards through their own direct experimentation. Feedback is vital, but it need not be complex. Devices like the simple rate clock fridge magnets trialed in Ireland are good for time-of-use tariffs.

If a smart meter display unit shows the change in tariff and the current cost of consumption, there is an immediate feedback loop.

In the longer term, utilities will need to show some ankle if customer psychology is to be transformed from borderline hate to love.

Ben van Gils, Ernst & Young’s global leader for power and utilities, said it’s not about products, it’s about the relationship. “In our experience, utilities tend to think they are not successful because they haven’t introduced the right product. In reality, the negative perceptions that consumers have of energy providers has resulted in limited permission for energy providers to stretch into new products and services.

“This lack of permission creates a huge obstacle for utilities, and minimizes the chances that any product, regardless of how good it is, will be taken up by customers. The quality of consumers’ experience with utilities must be improved before the relationship can stretch any further. Essentially, consumers want a voice; they want to be listened to and treated as an individual. Brands and companies that can offer this are the ones that earn their trust and loyalty,” he added.

So there you have it: Customers need to feel the love wherever they may be.

Energy from waste generates cash

anaerobic_digestion_002_2

Harnessing energy from waste enables companies to cut costs as well as carbon emissions, but there is potential for greater progress, as Tim Probert discovers. This article first appeared in the special report, ‘Managing Waste’, published in The Times on 5 March 2014.

Every year the average person in the UK generates 500kg of waste. Of this, half usually ends up in landfill. Driven by the EU directives on waste, for which the UK must reduce landfilling to 35 per cent of biodegradable municipal waste on 1995 levels by 2020, Britain is making strides to turn waste into energy and wealth.

Energy from waste (EfW) is not particularly new. Landfill gas has been used for decades and generates more than 5,000GWh a year of electricity from over 1GW of installed capacity.

Similarly, the large, typically 250,000 tonnes a year waste-to-energy plants burning unsorted, municipal solid waste (MSW), popularly known as incinerators, generate around 2,300GWh a year from approximately 600MW of installed capacity.

The landfill tax introduced in 1996, which saw councils charge a tax of £8 a tonne of material disposed in landfill, is perhaps the single most effective piece of legislation to incentivise efficient waste management practice. It has transformed the perception of waste to that of being a resource. A landfill tax escalator has seen the level steadily rise to £80 a tonne, with Chancellor George Osborne putting a floor under this figure until 2020.

Moreover, almost all EfW projects are eligible for three main revenue streams. These are the gate fee paid for processing waste instead of paying the landfill tax; the sale of the produced electricity; and one of two incentive regimes – renewable obligation certificates and feed-in tariffs.

Although so far not widely deployed, the Renewable Heat Incentive offers an additional inducement primarily for CHP (combined heat and power) anaerobic digestion (AD) plants. Non-CHP incinerators do not qualify for support.

Local opposition to thermal treatment technologies or incinerators can be fierce. Concerns are often raised about the health implications and the wider environmental impacts of burning waste. However, government and the industry argue the evidence shows the thermal treatment of waste is safe, while plants using cleaner technologies, such as advanced gasification and pyrolysis systems, which create synthetic gas and reduce air pollution, are increasingly common.

But there are fears market saturation has created overcapacity and undersupply of energy feedstock, with some councils locked into punitive contracts to provide waste to incinerators instead of recycling. Indeed, fears about potential white elephants have forced the Department for Environment, Food & Rural Affairs to withdraw hundreds of millions in funding to build new incinerators.

According to Nigel Aitchison, partner and co-head of environmental at investment management firm Foresight Group, talk about overcapacity is misplaced. He says: “When people talk about overcapacity they tend to talk about municipal waste, not the full waste market including commercial and industrial (C&I) waste produced by manufacturers, industry, hotels, restaurants and so on. In dry recyclables, there may be overcapacity and a number of facilities have closed, but there haven’t been any closures of EfW plants.”

The trouble is nobody is quite sure how much waste there is available or will be in future. It is widely accepted that the waste datasets are not fit for purpose.

Waste management consultancy Ricardo-ASA assumes that by 2020, there will be 53 million tonnes of MSW, C&I, and construction and demolition waste in need of treatment at thermal, organic and sorting facilities. On current capacity projections, however, this is 15 million tonnes more than both the operational facilities and known infrastructure likely to be delivered by 2020.

The absence of reliable waste data is a major hindrance to investors; this applies to both the quantity of waste and the detailed information about its composition. The lack of sound data using a common methodology makes putting a business case together challenging and one of the core reasons for limited financing for new infrastructure.

“What we’ve seen is a number of EfW projects that haven’t gone forward, not because they haven’t got the land or planning permission, but because they didn’t adequately structure the project in a way which meant it was investable,” says Mr Aitchison. To this end, the role of the Green Investment Bank (GIB) as a cornerstone investor is increasingly important, particularly for larger EfW projects.

Foresight Group recently forged a consortium with the GIB to construct a £47.8-million 10.3MW recovered wood gasification project in Birmingham. The GIB also invested £20 million in a 49MW waste-to-energy plant on Teesside in a consortium of SITA UK, Sembcorp Utilities UK and Japan’s Itochu.

Mr Aitchison sees AD as a significant area for growth. This uses natural bacteria, which breaks down waste to produce biogas for power and heat generation, and slurry which can be used for fertiliser.

AD accounts for more than 500GWh a year of electricity generation from 122MW of installed capacity, a tenfold increase in only five years. There are two main segments of AD – source-generated food waste (SSFW) and on-farm AD. SSFW units tend to be the larger of the two, typically 1 to 1.5MW with approximately 30,000 tonnes a year capacity. On-farm AD typically comprises sub-500kW units.

The planning process for AD is considerably less controversial than larger waste management incinerators because they are smaller, less intrusive facilities and are usually designed to manage locally sourced waste. Mr Aitchison has an eye on a possible move to ban food to landfill, as proposed by the Labour Party should they be successful at the 2015 general election, as giving a big boost to the AD sector.

Figures from the Waste & Resources Action Programme estimate 7.3 million tonnes of food waste is produced by UK households each year. “There is a progression to incentivising this,” says Mr Aitchison. “A landfill ban on food waste, which some people have said would be difficult to police, would undoubtedly be a benefit.”

There are some caveats. The UK as a whole is poor at collecting waste material, with more than 100 different ways used to collect waste, be it bag, box or bin. Indeed, most local authorities do not collect food waste separately.

Furthermore, the Department of Energy & Climate Change (DECC) last month confirmed feed-in tariffs for AD would be cut by 20 per cent, which the Renewable Energy Association fears will make some sub-500kW projects uneconomic.

If the Labour Party gets in in 2015 and keeps its pledge to ban food waste from landfill, however, AD is likely to be back in vogue.

2020 vision: A look at the European electricity market

europe light pollutionThis article was first published in the January/February 2014 edition of Intelligent Utility magazine

Europe’s electricity market is a mess. The clash between the European Commission’s desire for a single European market and national considerations of renewables targets, carbon emission reductions, price regulation and “keeping the lights on” is profound and getting harsher.

In effect, Europe has two power generation markets—one that is subsidized and does not react to market signals, and one that is not subsidized and driven by market forces. The growing surplus of intermittent wind and solar is a nightmare for utility companies for many reasons, and the problem is only going to get worse for Europe’s transmission and distribution system operators.

With 230 GW of wind and 120 GW of solar expected to be installed in the European Union by 2020, things have got to change. Utilities say the only solution is the complete integration of renewables into the market, and this must be done urgently.

This is easier said than done. Unlike the U.S. and FERC, the European Union has 28 member states with 28 governments, electricity regulators and national grid companies, not to mention collectively thousands of distribution network operators (DNOs). Each country works to its own interest and so harmonizing electricity policy is almost impossible.

While the Commission seeks to turn Europe’s 28 national power grids into effectively a single grid with power traded freely across it, plans by Member States such as Germany and the UK to introduce capacity markets risk the viability of such a unified system. Yet the world where European generators could calculate their business case by being certain of 6,000/7,000/8,000 hours of operation has gone.

Capacity markets are arguably justified in countries where there is too much renewable generation, insufficient conventional generation and where the grid is inadequate, and so the Commission has a battle on its hands to keep the single European market project on track, despite a growing surplus of 100 GW above peak demand in normal periods. The battle may already be lost.

Klaas Hommes of Dutch TSO TenneT BV sees great upheaval in the European energy market. “Feed-in tariffs are disturbing the market across Europe. An excess of solar power in Germany suppresses power prices in the Netherlands, meaning gas-fired and even coal-fired power plants are increasingly out of the money.

This is symbolized by the transfer in 2013 of a generator from the Enecogen combined-cycle gas turbine plant in Rotterdam, which had been operational for little more than a year, to Israel Electric Corporation’s Gezer gas plant near Tel Aviv, located some 2000 miles away,” said Hommes.

“We see the strengthening of the energy-only market and complete European market integration of renewables as the only answer,” added Hommes. “However, we are really concerned at the speed of progress.”

Hommes sees the need for more flexibility due to the greater challenges in balancing from one hour to the next. Furthermore, the increased flow from northern Europe to southern Europe and from Central Europe to Northwestern Europe will increase pressure on grids not designed to do so.

“The European market is no longer a day-ahead market, it is increasingly shifting to a near real-time market,” said Hommes. “This will require more cross-border co-operation and ownership of TSOs, more co-ordination between grid and generation and more system support services to be delivered by DNO/DSOs and third-parties.”

Hommes sees a greater role for ancillary services, with even a role for wind and solar power to provide active power, if not reactive power for voltage control.

Meanwhile, the need for grid investment continues apace. The European Network of Transmission, System Operators for Electricity (ENTSO-E) expects 100 bottlenecks on the European transmission system by 2020, requiring a 17 percent increase in grid investment worth 104 billion euros, equivalent to 52,300 kilometers of wire. Whether this investment will actually be forthcoming in an “austerity era Europe” is another matter.

Longer term, ENTSO-E’s eHighway2050 project is actively exploring the development of ‘electricity highways’, or transmission lines with significantly more capacity to transport more power than existing high-voltage lines in the AC grid.

If there can be any certainty about Europe’s electricity sector thru 2020, it is that the role of DNOs will become something akin to a DSO (distribution system operator). This is seen as crucial if Europe is to successfully integrate the ever-increasing growth of distributed generation, said David Trebolle, manager of Spanish DNO Gas Natural Fenosa’s active networks and control systems and chairman of Eurelectric’s DSO network codes technical group.

“Passive distribution networks will evolve to active distribution systems,” he said. “System services like congestion management, voltage control, information exchange, connection and planning are fundamental tools to maintain security of supply and quality of service at the distribution level. We will have new grid codes and ancillary services along the way.

“Real-time and near real-time networks are becoming more of a challenge. This will mean more opex spending as opposed to capex spending, and this will need a change in the regulatory regime. For this change to happen, better co-ordination between TSOs and DSOs are a must.”

Peter Styles, chairman of the European Federation of Energy Traders’ electricity committee, says an inevitable change to the way renewables are supported—from feed-in tariffs to quotas or certificate schemes—will open up new market opportunities. “With market-based mechanisms, there will be exposure to negative prices for renewables producers, meaning they will be subject to re-dispatch, possibly easing the path towards a new type of interruptible contract,” he said.

“National renewable schemes will require cross-border validity and thus reform of existing national renewable schemes will be necessary; cases currently before the European Court of Justice may accelerate this change,” he added. “For the future benefit of renewables, the Commission will revisit whether it will have grid priority access and dispatch, and whether renewable generators are immune to grid congestion management mechanisms.

“Exposure to balancing responsibility for renewables generators will open up the possibility for virtual power plants operated by owners of a mixture of types of plant and better return on investment for storage and demand response.”

Scottish Enterprise opens tidal cable competition

Why will Hinkley Point C cost £16bn?

Hinkley-Point-C-6134662The reported costs of the proposed Hinkley Point C nuclear power plant rose from an expensive £10bn in 2012 to an eye-watering £16bn within the space of a year. Why so much?

During a 21 October investor conference call, the CEO of the French state-owned utility EDF, Henri Proglio, estimated the construction cost of the 3260 MW, twin EPR reactor project at £14bn, “in line with the amounts committed to the EPR at Flamanville,” i.e. £7bn each.

EDF estimates a further £2bn will be necessary due to the specifics of the UK regulatory regime and site specifics of Hinkley Point C. The total estimated project cost, therefore, is £16bn.

Thomas Piquemal, EDF’s group finance senior vice-president, confirmed the additional £2bn did not include construction costs. “The investment cost is estimated to be £16bn, consisting of £14bn of construction costs and £2bn of other costs such as the acquisition of the sites, preparatory work for the various regulatory authorizations and the training of the 900 future employees of the nuclear station,” he said.

Later in the conference call, Proglio spoke of a “series effect”, i.e. a reduction in construction costs arising from experience learned the hard way from the long delayed and over-budget Flamanville 3 EPR project in Normandy, initially estimated to cost €3.3bn (£2.7bn).

Proglio said: “There is a series effect since we took lessons from our experience in Flamanville 3 and in Taishan [China] and compared to the cost of Flamanville 3 we are able to reduce significantly the cost of an EPR if we were to build a new Flamanville 3.”

Proglio went further, saying, “If we had to build a new Flamanville 3 it would cost £2bn less”.

That would put the cost of a new EPR reactor in France at £5bn, rather than £7bn for Flamanville 3, and suggests the overall construction cost of Hinkley Point C could be £12bn (£10bn for two EPRs + £2bn for “specificities”) rather than £16bn.

Yet the construction cost of EPRs at Hinkley Point C remains at £7bn each, exactly the same as the delayed, hugely over-budget Flamanville 3.

Pressed on this by a curious journalist from French newspaper Les Echos, who was clearly wondering how the “series effect” seemed to have no effect on the construction cost of EPRs built across la Manche, Proglio gave this contradictory response:

“The lessons learned…are offset by the site specificities for Hinkley Point, the regulatory environment in the UK and all specificities for HPC. The significant decrease offsets the additional incremental work that we have to perform and to carry out at Hinkley Point.”

But didn’t Monsieur Piquemal say that site specificities were accounted for by the £2bn on top of the £14bn construction costs? Confused?

Proglio tried to explain. “We have to have many ancillary buildings at Hinkley Point C that we don’t need for Flamanville. The site has a geologically different nature, softer ground and we have to do more earthworks and to put more concrete underground as a consequence.

“We have to take into account the fact that the Severn estuary is the large tidal flow location and there are many issues of that nature which leads to a more expensive cooling system when you are going to get the water in the sea to cool the power station.”

Although EDF says a new EPR in France would now cost £5bn, in Britain it is, in effect, £8bn. As Hinkley Point C is a twin reactor project, the difference between a ‘new’ twin-reactor Flamanville 3 and Hinkley Point C would be effectively £6bn.

Even allowing for the additional regulatory/site specifics plus land, training costs etc., does it really cost £6bn more to build two reactors of the same design in Britain than in France? Evidently so.

This matters because the British government wants consumers to pay for Hinkley Point C via an index-linked feed-in tariff at £92.50/MWh for 35 years (which during the conference call even EDF Energy CEO Vincent de Rivaz calls a “high price”). This, remember, is for a 3260 MW power plant that EDF expects will have an availability factor of 91%.

In his ‘flabbergasted’ note published on 30 October, utility analyst Peter Atherton of Liberum Capital estimated that Hinkley Point C would earn EDF and its investment partners up to £80bn over the 35-year lifetime of the deal. If EDF had overpriced Hinkley Point C by 25% it could cost British bill-payers up to £20bn in additional subsidies.

Proglio concluded the British government had examined the figures and were satisfied with the £14bn+£2bn cost, whichever way it had been calculated.

“[This is] fully understood by the government because all those costs have been scrutinized, analyzed, challenged by government, by the consultants and they have been convinced that these costs are justified and they are in the strike price,” he said.

The full transcript is well worth a read. It contains information about the nature of the Hinkley contract, especially its financing, which is not disclosed in either the 21 October DECC press release or EDF press release.

This includes EDF Energy CEO Vincent de Rivaz saying decommissioning costs had been factored into the strike price at between “£2-2.50/MWh with a cap at £3/MWh and any difference will be passed through to consumers”.

De Rivaz also states the Hinkley Point C contract would contain “protection mechanism against adverse changes in expected operating costs such as uranium price or labour cost, and changes in other costs which are out of NNB controls such as transmission charges and business rates.”

The death spiral – Australia’s changing grid

This article first appeared in the November/December 2013 issue of Intelligent Utility magazine

BIGCSIROb_edit_crop_smallBy now most will be aware of the dreaded utility “declining demand death spiral”: As solar PV grows, utilities’ demand drops. Utilities respond by raising prices and/or network charges—either for solar or non-solar customers—further incentivizing solar (and battery storage), thus further reducing demand.

Few places are more likely to experience the death spiral than Australia—a vast, sun-drenched nation with huge distances between urban and rural populations.

The highly-populated East Coast National Energy Network—connecting Queensland, New South Wales, ACT (Australian Capital Territory), Victoria, South Australia and Tasmania—currently has 3 GW of solar PV out of 35 GW peak demand. Yet, this relatively small proportion is having a material impact on utilities.

Queensland regulated utility Ergon Electricity, which operates 160,000 km of power lines in a territory of 1.7 million square kilometres with only 700,000 customers, is shedding hundreds of jobs in an effort to stay competitive with solar suppliers who do not have a distribution grid to support.  Utilities are fighting back with an increasing rejection of rooftop applications due to network constraints, but the rising tide of solar will only get harder to stem as solar costs fall.

Distribution network service providers (NSPs) are keen to introduce a residential capacity charge for solar power, effectively a tax on the sun, to mitigate the death spiral. But this, of course, may also have the opposite effect. In Australian states where rooftop solar PV power generation in winter is adequate (such as Victoria, South Australia and Tasmania), consumers may begin to desert the grid.

It is with this in mind that CSIRO (Commonwealth Scientific and Industrial Research Organisation) is studying the likely impact of a potential death spiral. CSIRO is leading a report by the Future Grid Forum (FGF) —due to be published by the end of 2013—with input from input from virtually every Australian generator, transmission and distribution network operator, plus regulators, consumer groups and regional/national government.

“By 2030 we fully expect to have more solar power generation during the daytime than the grid can deal with,” said Dr. John Ward, CSIRO research leader. “Australian peak demand occurs during the middle of the day. But if the take-up of solar increases as expected, this will shift to early evening, and the need for load management during the early evening becomes considerably more important.

“The nature of the ‘death spiral’ is that it leaves those not in a position to go off-grid in a very bad place. Furthermore, we may have to run a 100 percent redundancy system with large amounts of spinning reserve, as well as paying to deal with voltage control problems at the distribution end.”

The FGF has been discussing in detail how the industry can move to a more cost-effective solution. “The high penetration of solar power will require either balancing prices to rise significantly or a fundamental change in the market and we have been discussing this at length,” said Ward.

One way could be battery storage. Australia’s solar feed-in tariff is roughly equivalent to the wholesale price, and consumers can already start thinking about using storage to manage the price differential between peak (A$0.525/KWh) and off-peak (A$0.137/KWh) regulated prices.

Ward added, “Power suppliers are certainly thinking about selling systems rather than merely electrons, but it’s murky territory having a generator or NSP having involvement with equipment on the customer-side of the meter. It’s not quite clear how this will play out, but the NSPs in particular are looking at this from the perspective of network upgrade costs. Is there a more cost-effective solution which involves storage on the customer’s site and how they make that work from a regulatory point of view?”

NSPs have been exploring exactly this in trials. The Smart Grid Smart City project by Ausgrid, which operates the distribution network in the Sydney, Central Coast, Hunter Region and Newcastle areas of New South Wales, deployed both battery storage systems and fuel cells outside of the usual regulatory environment to answer questions about social acceptance of the technology.

CSIRO is also working on a number of research projects to better understand the relationship between solar power, storage and the grid.  The projects are concentrated in remote communities, where power prices are highest and power quality is lowest. One such project, called Plug and Play (PnP), is motivated by improving understanding of solar generation forecasts in order to reduce spinning reserve, i.e. diesel generators, or replace it with energy storage.

CSIRO is undertaking the A$2.9m ($2.8m) project with ABB Australia and the U.S. National Renewable Energy Laboratory (NREL). The first phase of the project will involve the development of the technology; the second phase will see pilot systems set up in both the United States and Australia.

Users will be able to “plug” in the generation sources and the system will “play,” i.e. work out which source to use based on programmable parameters, such as maximising power availability, minimising diesel usage or lowering maintenance costs. In essence, PnP will make the decision when to schedule the diesel generator, when to use solar energy and when to charge the batteries.

Dr. Ward says forecasting is crucial to the process. “The better we can improve load and  generation forecasts the better we can improve the energy management system, i.e. the batteries,” he said.

Ward adds PnP will be a useful tool for microgrid project developers who want an out-of-the-box solution rather than custom-made hardware and software for each installation.

“As the electricity grid evolves to have more interplay beteen consumer demand and resource availability, there’ll be a role for PnP-type systems to become mainstream in every part of the electricity grid,” he noted.

‘Blackout’ Britain? Waking up to demand-side response

Photography for EnerNoc Web site and publications of new NOC facility.From National Grid to Distribution Network Operators and energy suppliers, demand-side response is seen as having great potential for tackling the Britain’s growing problem of how to keep the lights on. Tim Probert surveys the scene. This article was first published in the November 2013 issue of Energy World.

As surely everybody will now have realized, the state of the UK energy market is far from ideal. Having sweated its power generation assets for the best part of a quarter of a century post-privatization, the country finds itself in a panic about ‘keeping the lights on’, as an increasing volume of decrepit coal, oil and gas-fired generation is decommissioned.

While Parliament debates the Energy Bill to incentivize new generation under Electricity Market Reform, transmission system operator (TSO) National Grid has taken more immediate action by proposing rewarding larger power users to reduce consumption between 16:00 and 20:00 on weekdays in winter, as well as increasing the use of Short Term Operating Reserve (STOR) and other balancing mechanisms. The subsequent sturm und drang in the tabloid press about ‘power rationing’ and ‘Blackout Britain’ belatedly brought demand-side response (DSR) to the fore.

Very much under the radar there has been a quiet revolution in National Grid’s Short Term Operating Reserve (STOR) balancing product. Introduced in 2007, STOR is designed to ensure sufficient operating reserve to replace sudden generation losses, or unpredictable changes in demand.

National Grid procures around 3 GW a year of STOR, a large proportion of which must be available within 20 minutes. Driven by National Grid’s decision to offer 15-year contracts in June 2009, there was a brief boom in large STOR new-build projects. Green Frog Power, for example, supplies 214 MW from fourteen diesel-fired generator power plants rated between 6 and 20 MW in Yorkshire and South Wales.

There are two forms of STOR contract, firstly the committed service, which applies to all providers who wish to make themselves available for all required windows nominated by National Grid.  Balancing Mechanism (BM) units, typically sub-50 MW plant such as open-cycle gas turbines, and non–BM units, such as smaller diesel generators, can tender for this service.

The second form, which applies only to non-BM units, is the flexible service, which allows the provider to make the unit unavailable for particular windows on a week-ahead basis. Participants can reduce their load and/or use back-up generators to make up the shortfall (peak lopping) or export power from on-site generators to the grid during agreed times.

Only 10-15% of flexible STOR, however, is actual demand reduction, or ‘turndown’. While an effective measure, heavy use of diesel is not the most economically efficient or environmentally friendly and there is a growing trend towards genuine demand reduction measures to save costs and, of course, save the planet.

To be awarded a STOR contract, participants must guarantee a minimum of 3 MW capacity. Larger participants often contract directly with National Grid, but not all willing participants are able to supply this amount of reserve. However, commercial aggregation service providers, which now comprise around half of the non-BM unit STOR capacity, create a basket of participants who together comprise 3 MW or more.

Aggregators agree a strategy with the participants, typically data centres, offices, hospitals and factories, and bid the collective capacity into the balancing market. In return for offering bidding services and sometimes ‘free’ metering and IT equipment, aggregators take a cut from National Grid’s availability and utilization payments.

One such aggregator is KiWi Power. The London-based firm manages just under 100 sites in total, including Hilton hotels, Gwynedd Hospital in Wales, East Midlands Airport and J Sainsbury’s distribution depot Hams Hall, taking a 30-50% margin of DSR payments from National Grid. Like with financial services, KiWi Power packages 3 MW portfolios of sites in close proximity which statistically sit well together in terms of load profile; typically a hospital, a shopping centre and a hotel, to ensure one site can pick up the slack if another is unable to reduce consumption.

Increasing role for DNOs

While National Grid is responsible for STOR, Ofgem is offering distribution network operators (DNO) demand-side response incentives under its 2015-2023 price control regime price control, RIIO-ED1 (Revenue = Incentives + Innovation + Outputs). As a forerunner, DNOs are currently conducting trials as part of the £500m Low Carbon Networks Fund.

This summer, UK Power Networks (UKPN), which operates London’s distribution network, worked with KiWi Power to conduct a series of DSR trials. Over the course of the summer, UKPN called on KiWi Power’s customers to deliver a total of 45 times across its portfolio, delivering a total of 47 MWh of DSR.

Whereas National Grid pays on an undifferentiated rate, the trial was part of UKPN’s £23.8 million Low Carbon London scheme and thus paid differently. The ‘greener’ the DSR, the better it pays; a hotel reducing air conditioning load is, therefore, more lucrative than a hospital firing up a generator.

When this writer visited the offices of KiWi Power on a summer evening during a rare heatwave, we were interrupted by a phone call from UKPN requiring an immediate drop in load.  KiWi Power responded by cutting the air conditioning load from four hotels, as well as ordering a hospital to start a diesel genset. Over the next hour, consoles display the sites steadily reducing consumption.

John Conlan, Director of Facilities & Project Management at Mariott International Europe, decided to participate in the trial after being convinced by US utility Constellation Energy’s DSR performance at its Las Vegas hotels, investing £4000 per site on metering and related equipment. Conlan believes the flaw in the DSR plan – reducing load when it is needed most – is not a major problem.

“At the moment it doesn’t get any more sweaty than this,” he said. “No amount of payment from DSR is going to be of value if it has a negative impact on our guests, particularly in Central London. We’ve had a number of [DSR] calls, but had no negative comments from our guests.”

UKPN says the trials have given it confidence in using DSR as an alternative to network reinforcement as part of RIIO-ED1. Martin Wilcox, UKPN’s Head of Future Networks, said its RIIO investment plan identifies £38m of savings from using DSR, not only from working with aggregators like KiWi Power, but also by cutting out the middleman and providing DSR directly to customers.

“The 2015-2023 plan has a different flavour from previous DNO price control periods. The UK faces supply challenges over the next decade and we are being incentivized to reduce demand.

“As a DNO, we have natural advantages given our already strong relationships with larger customers. At the time of new connections to our network, there’s a great opportunity to discuss how to make new buildings ‘demand-side ready’.”

Electricity North West, the DNO which serves Greater Manchester, is one step ahead of UK Power Networks. Its ‘Capacity to Consumers’ (C2C) project aims to release redundant assets in its high voltage network and offer customers to provide DSR in a post-fault scenario.

The firm likens its network to having three hard shoulder motorway lanes which could be released as capacity to customers as demand increases. C2C seeks to offer customers connecting directly to its high voltage network (132kV and 33 kV) the opportunity to reduce distribution charges in return for agreeing to a delayed restoration of power following an outage. Typically, power is restored within an hour but C2C-managed customers can be delayed up to a pre-agreed period, usually eight hours.

Electricity North West is trialling C2C with both new and existing customers. The latter are rewarded with payments for entering into post-fault DSR, new customers have an additional incentive: avoidance of high voltage network reinforcement charges and reduced connection asset costs.

Electricity North West mitigates the need for network reinforcements by changing the electrical configuration of the primary substation, i.e. closing the normal open point and taking control of the network within its management system. This is achieved by fitting remote control equipment to a customer’s incoming circuit breaker connected to the primary substation.

C2C is being trialled until September 2014 to better understand network performance with altered configurations. Electricity North West expects a small increase in overall fault levels; it also faces issues with 6.6kV switchgear, which will require changing.

Due to the nature of this programme, customers must make themselves available 24/7 and the inherent risk to participants has not led to a surge in C2C; just three companies have participated, equivalent to 1.5 MW.  Simon Brooke, Low Carbon Networks Manager, says most interest has come from small manufacturers, with large manufacturers preferring, so far, to be in charge of their own destiny.

“We need to understand better how price points change for different customers and draw up attractive contracts to persuade customers to provide post-fault DSR,” he says. “It’s not merely placing a value on reduced connection and reinforcement charges, but also on how customers are providing security of supply to other customers on the network.”

DNOs to DSOs?

For the time being, however, the role of DSR for DNOs is expected to be limited. DNOs are by nature relatively passive and non-innovative, doing little more than owning wires and printing money. But with increasing volume of intermittent generation, what goes on between the half-hourly balancing periods becomes more important and the UK is arriving at a point where DNOs have to become more involved.

Craig Dyke, National Grid’s Strategy Development Manager, says over the next decade the role of DNOs is changing to one of running largely passive networks to a more active distribution system operator (DSO). “National Grid needs to work much more closely with DNOs to understand what’s happening on networks and how it impacts on transmission,” he says.

In October 2012 National Grid created a working group with the DNOs to understand the future role of demand-side response, the DSR Shared Service Framework, including the role of suppliers and aggregators.  National Grid, of course, does not think demand reduction is always necessarily a good thing.

“With increasing volumes of wind on the system,” says Dyke, “We are seeing excess supply at night, and we want to be able to increase demand at these times, perhaps from electric vehicles and heating, to reduce curtailment. DSR is all about peak demand – 4 PM to 8 PM on weekday evenings, particularly in winter.”

DECC knows this all too well. Its Electricity Market Reform (EMR) package tackles this problem head-on, including as it does a capacity mechanism to boost generation capacity to ensure the lights stay on at these peak times.

Capacity Mechanism role for DSR

As part of the capacity mechanism, DECC is grappling with how to introduce incentives for DSR. The department has wisely ruled out a ‘negawatts’ feed-in tariff, rewarding commercial investment in energy efficiency according to the level of energy that would otherwise have been consumed.

Instead, DECC will incorporate a DSR element of the capacity mechanism with different rules from those for generation capacity. DECC estimates there will be at least 1 GW of DSR purchased in capacity market auctions but as yet the market is insufficiently designed to tell if it will work, says Lisa Waters of the Waters Wye Associates consultancy.

“DECC has said DSR participants will be able to bid at higher prices than under the capacity mechanism, recognising that participants may need to invest in new infrastructure to fulfil the requirements, but it’s having trouble determining how the DSR is measured,” she says. “For example a 50 MW steelworks would be ‘derated’ by DECC to 40 MW, and the baseline for judging whether it has delivered DSR will be based on recent historical consumption data.

“I think they may struggle with that. If the steelworks has committed to DSR and suddenly the global economy picks up boosting demand for steel, it will be very difficult for boardrooms to be persuaded about the benefits of DSR, particularly as DECC said it will impose penalties for lost load of greater than £3000/MWh.”

The capacity mechanism, however, has one key feature which may ultimately lead to a radical approach to DSR, much to the benefit of the ‘Big Six’ vertically integrated utilities. Cost recovery in the capacity mechanism will depend on the level of peak load, i.e. punished for high load at the system stress peak. Suppliers will therefore be incentivised to contract for more demand-side response, or seek customers which have very flat load profile and ditch those with peak load, or at least charge them accordingly.

Chris Harris, Npower’s Head of Retail Regulation, cites research by Redpoint that predicts energy unserved could rise from almost zero in 2013 to 6 GWh by 2020. In other words there is a 20% chance of a brownout by the end of the decade.

“We are staring at lost hours in the face, but unused [generation] capacity is expensive,” he says. “There needs to be a paradigm shift away from inelastic demand and flexible generation to demand-side management. We must turn the existing model on its head and have a consumer-driven, rather than production-driven, system.”

For Harris, this means effectively shifting the suppliers’ burden of having spare generation capacity on to consumers by making them pay a premium for using electricity at peak times.

“We need to deliver full price signals. Our regulatory solution has always been to back off from this but it’s simply not efficient. Consumers will pay more but if you keep driving the price signal high enough they will change their behaviour to reduce their bills so that they’re better off than they were before.”

Npower ultimately wants to be able to directly communicate with devices via smart meters to directly reduce demand rather than have consumers running around switching off the heating. “It’s about moving heat load to a cheaper time of day,” says Harris. “In a smart world we will be able to manage the [heating] device remotely to automatically respond to price signals.”

Keith MacLean, Head of Policy & Public Affairs at SSE, thinks effectively doubling Granny Smith’s energy bill overnight would not be tolerated by politicians. “I don’t think we’re politically brave enough to vary electricity prices enough to make changes.

“The real opportunity to make a difference in our domestic energy consumption is in heat rather than power. Keeping the lights from going out by telling people to turn off the lights is not a good way of doing it, but we need to be prepared to legislate and regulate if aggregating and automating DSR is the right solution.”

Aerial shot of Sellafield

Tim Probert examines a dilemma for the Government: what to do with the plutonium stockpile at Sellafield, as well as the long-running saga of developing an underground depository for nuclear waste. This article first appeared in the October 2013 issue of Energy World.

What was once thought to be a valuable asset is now a costly liability. Britain has accumulated the biggest pile of civil plutonium in the world and it is now struggling to decide what to with it.

The plutonium stockpile at Sellafield is primarily an accumulation of Britain’s atomic weapons programme, the Magnox reactors, as well as the failed fast breeder reactor programme, which sought to use reprocessed spent fuel in anticipation of a global shortage of uranium, a shortage that never materialized.

In total, the stockpile currently stands at approximately 120 tonnes and growing. The Nuclear Decommissioning Authority’s (NDA) Thermal Oxide Reprocessing Plant (THORP), which takes in spent fuel from both home and abroad, separating the uranium and plutonium for the former to be reused in reactors, generates an additional four to six tonnes per year.

The plutonium is currently safely stored in concrete bunkers in around 14,000, 7kg, stainless steel containers approximately 12 inches long. However, the volume of plutonium at Sellafield is said to be enough to produce 10,000 nuclear weapons and the Government estimates the annual cost of at approximately £80 million for the next 100 years.

Officially, the plutonium is not classified as a waste but as a zero-value asset. So the Government faces a dilemma; should it continue to treat the plutonium as a potential source of energy or simply write it off? Should it turn it into nuclear fuel for reactors, leave it in storage above ground at Sellafield or area deep underground in a geological formation in an as yet undesignated location?

In 2008 the Government asked the NDA to identify solutions for the long-term management of the stockpile. In response, the NDA published a ‘Credible Options Paper’ in 2011. After consultation, DECC set out three options for long-term plutonium management.

Firstly, re-use. The Government’s preferred option is to re-use the material, which it says contains enough energy to generate national electricity demand for 500 years, by using it in Mixed Oxide (MOX) Fuel. This would require the construction of a new MOX fuel fabrication plant.

Secondly, immobilise plutonium and treat it as waste. The plutonium stockpile could be immobilised so as to be ‘proliferation-resistant’ in several ways: through vitrification or using ceramics or cement-based grouts.

Thirdly, indefinite storage. This is the current default setting; plutonium will be stored at Sellafield until 2120 if no alternative is pursued.

Government’s preferred option

DECC’s preferred option of the MOX route is highly controversial. From start to finish, the original Sellafield MOX Plant (SMP) was a disaster.

The business case for SMP was predicated on British Nuclear Fuels Limited (BNFL) acquiring Siemens, including its MOX expertise. When the Siemens acquisition was abandoned, BNFL nevertheless proceeded with SMP, relying on its limited in-house expertise.

In an internal report released under a Freedom of Information Act request, the Government remarked, “As a result, SMP had significant gaps both in its design and operating capability. This meant that the plant was not fit for purpose and struggled from the start with a wide range of operational problems.”

Scheduled to open in 1997 at a cost of £265 million, SMP finally opened in 2001 at a cost of £473 million.  Yet it was not until 2005 that the first MOX fuel assembly was manufactured, forcing BNFL to subcontract their first orders to arch-rivals Areva in France. Remedial work was required, bringing the total cost to £490 million.

Designed to produce 120 tonnes of MOX fuel a year over a ten-year period, the SMP could only churn out 13.8 tonnes over its entire lifetime. The accident at the Fukushima Daiichi nuclear plant in Japan was the final nail in the coffin as it was left with no new potential orders for the MOX fuel.

In August 2011 the Government announced the plant was to close as soon as practically possible. The final cost to the taxpayer is estimated at £2.2 billion once decommissioned. US government cables released by WikiLeaks stated the plant to be “one of the most embarrassing failures in British industrial history.”

Yet despite this dismal failure, the government’s current policy is to construct a second MOX facility, estimated to cost between £5-6 billion. This is a particularly baffling policy decision given the total lack of customers for such fuel at home or abroad; there is only one power plant capable of using MOX fuel, Sizewell B in Suffolk, but owner EDF has not sought the necessary license.

EDF has also currently ruled out the use of MOX at Hinkley Point C in Somerset, should it be constructed. Horizon, the joint venture between E.ON and RWE subsequently acquired by Hitachi, which plans to construct new nuclear power stations at Wylfa in Anglesey and Oldbury in Gloucestershire has no plans to use MOX either.

Furthermore, the clear front-runner to win a contract to build another SMP is Areva, which is currently experiencing costly over-runs with its US project at Savannah River, South Carolina. The US General Accountability Office says the plant is more than three years behind its 2016 completion deadline and is now expected to cost $3 billion more than planned, ballooning to $7.7 billion in total.

The Obama administration says the high costs “may make the project unaffordable” and is looking for different ways to dispose of plutonium, such as immobilisation.

Other MOX technology options

MOX-2 is not the only technology option being reviewed for the Government’s preferred re-use route. Coming somewhat out of leftfield in 2011, the NDA announced it was exploring two other options: GE-Hitachi’s PRISM reactor and the Canadian Enhanced CANDU-6 reactors.

The PRISM reactor is a Generation IV sodium-cooled fast breeder reactor, also known as an integral fast reactor. The proposed solution would comprise two modular reactors generating a combined 622 MW employing metallic fuel, a mixture of the plutonium and uranium oxide, which would be produced at an adjacent fuel-fabrication facility.

Candu Energy proposes building four 700 MW Enhanced CANDU-6 heavy-water reactors to burn its own version of MOX fuel, which would require the construction of its own version of a MOX fuel-fabrication plant. Both options would be first-of-a-kind projects and this is inevitably likely to make the Government apprehensive.

In August the NDA sent its appraisal of the three technology options to DECC. The Government is not expected to make an announcement until after the political conference season has ended, but sources familiar with the consultation process suggest it is highly unlikely that DECC will give the go-ahead to ‘MOX-2’ of any variety for the foreseeable future.

“The government is under considerable pressure because of the large plutonium stockpile at Sellafield, but it has a history of delay,” the source said. “There is no immediate pressure to put shovels in the ground tomorrow because although you can burn MOX fuel in some of the new reactors, you first have to get those reactors built.  With the delayed new build programme, we are probably two decades away from being able to use MOX fuel in new reactors.”

That another MOX fuel-fabrication plant is even on the table is a triumph of public relations, according to Dr. David Lowry, an independent nuclear research consultant. “The nuclear industry is extremely successful in lobbying to convince the Government that it should build new projects,” he says.

“But no minister is going to come before Parliament between now and the General Election in austerity Britain and say they’re going to invest up to £5 billion in a new MOX plant knowing the last one was a complete disaster. They’ll kick it into the long grass.”

Going underground

Another Cumbrian nuclear legacy policy option in danger of derailing is the long-running geological disposal facility (GDF) saga. The on-off affair has rumbled on since the 1976 Royal Commission on Environmental Pollution report, popularly known as the Flowers Report, which recommended the foundation of a ‘Nuclear Waste Disposal Corporation’ to store High Level Waste and Intermediate Level Waste.

37 years later, Britain is barely any closer to finding a long-term solution to its nuclear waste. In January, Cumbria County Council voted against Government plans to undertake preliminary work on an underground waste repository, despite district councils Allerdale and Copeland having previously voted in favour.

Under current legislation, this would appear to rule Cumbria out of the equation: if a part of that community has said no then, strictly speaking, it should eliminate Cumbria from the process for good. However, DECC is consulting on the next steps.

It is thought unlikely that the Government will walk away from its current approach of encouraging a community to host the GDF voluntarily, but it could explore a revised process which would enable Cumbria to go forward with a GDF based on a decision taken below the County Council level.

Politicians have hinted that the veto of the GDF plans by Cumbria County Council could ultimately result in a merger of Copeland and Allerdale district councils to create a new unitary authority. Ultimately, however, Cumbria County Council is also the nuclear waste planning authority and would have to give permission to junior planning authorities for any exploratory drilling for a GDF.

Again, says Dr. Lowry, expect the Government to boot it into the long grass. “It may be that the Government keeps asking questions until it receives the ‘correct’ answer,” he says, “But I don’t think this will wash politically.

“The government will have to go ahead with interim storage at new nuclear sites. In the long-term there may be a version of a GDF, but I don’t think it will be deep underground, but shallow burial.”

 Low level waste headaches

The Government has another painful headache with the on-going problem of storing Low Level Waste (LLW). Past policy on the disposal of LLW and Very Low Level Waste (VLLW) has been for it to be stored in situ before being consigned to the UK’s only dedicated disposal facility: the LLW Repository (LLWR) at Drigg, in Cumbria.

Here, waste is placed into metal containers which are then placed into engineered landfill cells and then covered with concrete for long-term storage. However, this facility is expected to run out of capacity in the next ten years, and alternative options are being sought.

A number of conventional landfill sites – two in Cumbria, one in Lancashire and another in Peterborough – are seeking the necessary authorisations to receive LLW and for landfill disposal. However, problems with obtaining planning permission look likely to stall these developments, with only Waste Recycling Group (WRG) at Lillyhall in Workington and Sita in Preston being set to proceed because their sites have long had the necessary planning consents.

In May 2012, Cumbria County Council refused planning permission to use the Keekle Head former open cast coal mine in West Cumbria as a site to store up to a 1 million cubic metres of LLW for the next 50 years. Endecom, which aims to operate the facility, is hopeful Westminster will overturn Cumbria County Council’s decision following a public inquiry in June 2013.

Also in June, Sellafield Ltd was fined £700,000 and ordered to pay more than £72,000 costs for sending bags of LLW to a conventional landfill site. The five bags, which contained plastic, tissues and clothing, should have gone to Drigg, but were sent to the WRG Lillyhall site in Workington.

Sellafield said a faulty scanner used to monitor radioactivity levels allegedly allowed the bags of waste from a restricted area of the site to be passed for conventional landfill disposal.  The Environment Agency has managed to recover at least one bag of waste from Lillyhall, but the incident has cast doubt on the robustness of the controls needed to ensure that only VLLW and LLW are disposed of in conventional landfill.

Asset or liability?

Yet the most serious problem remains what to do with the plutonium stockpile. There are growing calls from environmentalists for it to be simply written off as waste and immobilised so as to be ‘proliferation-resistant’.

Using existing technologies, the only way to store the plutonium waste in the GDF would be to deposit small concentrations in cement. To deposit all the plutonium in this way would require around 200,000 tonnes of cemented waste at a cost of around £8 billion.

While vitrification has been successfully deployed for liquid HLW at Sellafield, the process of vitrifying plutonium is not yet technically proven and would still require long-term storage underground at an estimated cost of £5–7 billion. The NDA is assessing this option through studies at the National Nuclear Laboratory.

Independent nuclear consultant Steve Kidd, who recently left his post as Deputy Director General of the World Nuclear Association, says the Government would be unwise to write off the plutonium stockpile as waste.

“It is an economic asset rather than a liability,” he says, “It would better to keep it stored where it is for the next 30-40 years to be used by Generation IV reactors.

“People get very excited by plutonium but it’s not in a Pu-239 form which could be directly used in a bomb without further reprocessing. It would have to be a very clever terrorist organization who somehow managed to walk off it.”

Although it requires relatively expensive active management, the plutonium is safely stored at Sellafield and there is no reason it cannot be for the foreseeable future.

Whether for plutonium, high, intermediate or low level waste, none of the proposed solutions need rushing.  It is much more important to get it right than to get it quick because past attempts at a speedy solution have not been successful.

No prizes for policy wars

Tim Yeo’s decarbonisation amendment speech to Commons in full

I draw attention to my entry in the Register, especially my interests in energy industry.

In doing so I emphasise, as I have done before, that my views on climate change, on the need for Britain to move more swiftly to a low carbon economy and to cut its dependence on fossil fuels, were formed two decades ago when I had ministerial responsibility for this area of policy.

I’ve not changed these views at any time since then. I’ve repeated them publicly and privately on many occasions throughout the last 20 years. My views have never been influenced at any time or in any way by my financial interests.

All those interests were acquired after I left the Shadow Cabinet in 2005. That was 12 years after I accepted the overwhelming scientific consensus on this subject and began campaigning for a more urgent response to the challenge of climate change.

Various bloggers, columnists and others, including one or two Honourable Friends, who insinuate otherwise, and who ignore this scientific consensus, invariably overlook my strong and consistent support for nuclear power, a low carbon technology which should be part of Britain’s energy mix.

I’m grateful for this opportunity to debate the amendment in the name of honourable members from all parties and myself.

The amendment is based on a unanimous recommendation made in July last year in the Report of the Energy and Climate Change Committee on the draft Energy Bill.

The Govt accepted many of the Committee’s recommendations, and by doing so materially improved the Bill.

I congratulate my RHF the Secretary of State and his team on their response to our Report and on the outcome of their negotiations with the Treasury on a range of issues, including the LCF.

However for a variety of reasons the need for the amendment we are debating is even greater now than it was when my Committee’s Report was published.

Firstly, despite some positive signs about the Govt’s support for low carbon electricity generation, the publication on the day of the Autumn Statement of the Gas Strategy confused many investors.

The possibility that the Govt might sanction 37 GW of new gas fired generation capacity rests uneasily with its acceptance two years ago of the 4th Carbon Budget which covers the period 2023 to 2027. It suggests that the purpose of next year’s review of the 4th Carbon Budget is to water it down and weaken incentives for low carbon investment.

The understandably envious glances cast across the Atlantic by the Treasury at the transformation of the US gas market in the wake of the exploitation of shale gas have not passed unnoticed.

Not surprisingly there are now doubts in the minds of many prospective investors about the depth of the Govt’s commitment to decarbonising electricity generation.

On the issue of shale gas incidentally the ECC Committee was one of the first bodies to urge the Government, more than two years ago, to approve more exploration and testing to establish the scale of Britain’s shale gas reserves.

If our dependence on imported gas can be cut and if consumers can be protected against the fluctuations in international gas prices which have been the main cause of the rise in domestic energy prices in the last few years then that is wholly to be welcomed.

However my Committee also warned in our more recent Report on Shale Gas that it would be rash to base energy policy on the assumption that Britain will soon be a major shale gas producer.

The opposition to exploring for shale gas in Sussex which is already emerging is a foretaste of the battle for public opinion which must be won before domestic production of shale gas on even a modest scale can occur.

The case for a diversified energy mix is therefore as strong as ever.

Secondly, although we hear regular warnings about a looming capacity crisis in electricity generation, and the consequent risk of power cuts, there is a curious complacency about the Government’s attitude.

Investment in new generating capacity is now at a low level.

The nuclear talks between Government and EDF remain unfinished. Even if, as I now expect, they are brought to a successful though belated conclusion it will be 2020 at the earliest before a single KW of electricity is generated by a new nuclear power station in Britain.

New investment in coal is unlikely to occur until an economically viable form of Carbon Capture and Storage is available. Despite the huge potential market for CCS there is no sign anywhere in the world of this happening.

I am an enormous fan of CCS. It is the single technology the world most urgently needs to address Climate Change but we may have to wait another decade or even longer for a breakthrough on this front.

Meanwhile coal can currently be imported cheaply from America so our remaining coal fired power stations are running flat out.

Gas generation, the great white hope of many people, is currently so unprofitable that, far from large scale new investment taking place, some plant is currently mothballed.

Critically, potential investors in gas generation are holding back until the details of the Government’s proposed capacity mechanism are known. I urge my Right Honourable Friend to publish these details as soon as possible.

With a decision on nuclear still awaited and fossil fuel generating investment at a standstill it might be thought that money would pour into low carbon renewables. Even here the picture is unclear. For example, according to new figures from Bloomberg, the flow of funds is actually slowing down.

Doubts about whether a future Govt will stay committed to supporting low carbon technologies after 2020, fears that instead it will bet the farm on another dash for gas, and a lack of clarity about the level of strike prices to be proposed for the new Contracts for Difference regime have all unsettled investors.

The only certain consequence of this is that investment will be slower and the risk of a capacity crisis greater.

The element of perceived political risk will lead investors to seek higher returns for investment in the UK energy market.

Higher returns to investors mean higher prices for consumers.

My amendment directly addresses these issues.

By itself it will not immediately alter the low carbon pathway on which the Govt has already embarked, most notably by its acceptance of the 4th Carbon Budget.

But the prospect of the 4th Carbon Budget being watered down in next year’s review is simply another unwelcome uncertainty.

The amendment removes that uncertainty. It requires the Secretary of State to set, no later than 1April 2014, a decarbonisation target for 2030 for electricity generation.

As currently drafted the Bill merely gives the Secretary of State a power to set such a target without compelling him to do so. It also prevents him from exercising this power before 2016.

Suggestions that this amendment would force him to set the target at 50 grams per Kwh in 2030 are mistaken. The amendment requires him to set the target in accordance with advice from the Committee on Climate Change. If he does not follow the advice of the Committee on Climate Change he would have to explain why.

The CCC would not have a free hand in advising the Government. It would still have to take account of all the matters already referred to in the Bill in Clause 2 section 2. These include READ OUT (a) to (e).

http://www.publications.parliament.uk/pa/bills/cbill/2013-2014/0004/2014004.pdf

In truth therefore this amendment is not very revolutionary. It seeks to bring forward by a couple of years something which the Government is contemplating doing anyway.

If it is indeed true, as the Secretary of State asserted yesterday, that we are heading for substantial decarbonisation of electricity anyway, what objection to this amendment can there possibly be?

There is now very widespread support for it. Only two weeks ago the CCC published a report recommending that a target for reducing carbon emissions from electricity generation by 2030 to 50 grams per Kwh should be set in legislation, with flexibility to adjust this in the light of new information as the amendment provides.

A wide range of businesses and trade bodies have backed it. The Aldersgate Group for example, whose members include Microsoft, Marks & Spencer, Aviva, Sky, PepsiCo, British American Tobacco and others, are strong supporters.

Many companies with interests in the supply chain and with potential to create jobs in Britain want to see it passed.

A wide range of voluntary bodies are campaigning for it, including the Women’s Institutes,

Even among HMs there are signs of enthusiasm. At the Lib Dem Party Conference last September the Chief Secretary to the Treasury proposed a motion to establish, and I quote, “a target range of 50-100g of CO2 per Kwh for the decarbonisation of power sector in addition to existing carbon reductions.”

If every Lib Dem MP who supported the Chief Secretary that day joins me in the Aye Lobby at 4 o’clock the amendment will be carried. I am sure that all my Honourable Friends on the Lib Dem benches are keen to take this opportunity to strengthen their well known reputation for consistency.

Even the Government itself seeks powers in the Bill as it stands to introduce such a target. But for some reason they don’t want to do so until 2016 at the earliest.

The problem with this St Augustinian coyness, this promise of possible future chastity in the matter of greenhouse gas emissions but please God, not just yet, is that by 2016 many investment decisions will have been made.

If these lock Britain into a high greenhouse gas emission future they will either prevent us from meeting our climate change commitments or else will lead to the construction of fossil fuelled generating capacity which has to be subsequently scrapped.

2016 is also after the next General Election. Delaying a decision until then creates another needless but harmful element of doubt about the Government’s true intentions.

I therefore urge HMs on all sides to support this amendment. Doing so will remove an element of uncertainty whose presence hampers investment, increases the risk of a capacity crisis and raises electricity prices unnecessarily.

This amendment will not impose on the Government today any commitments it does not already claim to embrace.

Furthermore it will not remove the need for even greater priority to be given to demand side measures and to energy efficiency, issues which I wholly support.

By itself it will not raise electricity prices in the next seven years by a single penny because the total sums spent on subsidising low carbon electricity in the period up to 2020 has already been capped by the LCF.

By contrast the Treasury’s own cherished floor price for carbon does raise prices and add to consumer and business bills making British industry less competitive relative to the rest of the EU but does so in a way which does not cut emissions by a single kg.

Without the amendment this Bill, whose early passage through Parliament is desperately needed for economic and security reasons as much as for environmental ones, will be needlessly weakened.

I commend the amendment to the House.

Thorium nuclear power: Forever the bridesmaid?

Alvin Weinberg celebrates 6,000 operating hours of Oak Ridge National Laboratory's Molten Salt Reactor Experiment, a 7.4 MW thorium-based demonstration reactor

To the great surprise of the established nuclear industry, thorium and molten salt reactors could be on the verge of making a comeback. Tim Probert cuts through the growing hype to explore whether good ideas can ever become good business. This article was first published in the May 2013 edition of Energy World.

Thorium has enjoyed a remarkably high profile of late given its chequered history. Despite the fact most development programmes by commercial entities (though not research institutes) were canned in the 1970s and 1980s, an increasing amount of hyperbolic articles are being published in serious and not-so-serious outlets extolling the virtues of thorium.

In reading these articles, the reader may be led to believe thorium is something of an energy panacea. Thorium is a ‘green’ source of nuclear energy, they say, abundant, cheap, safe, without the drawbacks of core meltdowns and copious amounts of radioactive waste.

The truth, of course, is far more complex. While thorium does offer highly attractive potential advantages as a source of atomic power, there are also several considerable barriers to the development of thorium-based nuclear reactors.

Uranium’s head start

Some view thorium as the Wankel rotary versus four-stroke piston engine or Betamax versus VHS battles of the energy industry: despite its significant technical advantages over its rivals, the ‘lesser’ product won. There is a great deal of truth in this, and a short history lesson is required to explain why.

It is essential to point out Thorium-232 (T232), like Uranium-238 (U238), is a fertile isotope, not a fissile isotope. Both these isotopes have to be first irradiated in a reactor to produce their derivative respective fissile isotopes U233 and Plutonium-239 (Pu239) resulting from neutron capture decay chains, neither of which exist in nature.

To begin its nuclear weapons programmes in the 1940s, the United States decided to produce both enriched uranium in U235, the only naturally occurring fissile isotope in nature, and Pu239, produced from neutron irradiation of fertile U238 in a reactor.

The United States recognised but declined the third option to produce U233 from irradiation of Th232 in U235-enriched reactors for two main reasons. Firstly, it was known that U233 was a hard gamma emitter which would be both difficult to reprocess and to machine and handle from a personnel protection standpoint.

Secondly, and more importantly, it was demonstrated that the 0.7% level of fissile U235 in natural uranium was sufficient to be the basis for a nuclear reactor system, with the 99.3% U238 content in natural uranium hence being partially converted to produce around 0.8% of the new fissile element plutonium – unknown in nature – which could then be chemically separated through reprocessing.

Had the United States gone down the thorium route, there would have been a significant weapons programme delay in producing sufficient quantities of the required enriched uranium driver. Unlike uranium, thorium cannot be driven by a natural uranium reactor (since neutrons are absorbed by the U 238), only by an enriched uranium reactor.

Uranium, therefore, got a head start for civil nuclear power from which thorium has never recovered. Thorium research became a side show as a means to an end to produce U-233, the only other fissionable feed isotope.

The light water nuclear reactors (LWR) deployed in nuclear power stations developed simply as scaled-up versions of nuclear submarine reactors, again driven by military impetus. As a result, virtually the entire nuclear energy industry has been optimised around the uranium and, to a lesser extent, plutonium fuel cycles.

While thorium is three to four times more abundant than natural uranium, there is no shortage of the latter. At current usage of 68,000 tonnes/year, global proven resources of 5.3 million tonnes mean there is enough natural uranium for at least 80 years, notwithstanding spent fuel.

While there are many good arguments in favour of thorium, energy security is one of the weaker ones and governments may only turn to thorium if uranium economics or its geopolitical abundance becomes problematic, says P.K. Doshi, Director of International Business Development at nuclear consultancy Excel in Maryland, USA.

Doshi, who has 45 years of nuclear industry experience and also thorium fuel manager when Westinghouse Electric operated the world’s first pressurized water reactor with thorium cores (at Shippingport, near Pittsburgh) in the 1970s, is highly sceptical about thorium’s chances.

“The infrastructure is in place to support LWRs on the uranium cycle,” says the Indian. “It’s expensive to compete with an established infrastructure, particularly when the timeframe to develop an alternate is so long.  In this sense, thorium is kept down by ‘the system’.  But I don’t see it as a conspiracy, rather as an economic fact of life.”

Molten salt reactors: The next big thing?

It is the job of the Weinberg Foundation to challenge ‘the system’. Founded in 2011 to promote thorium energy, the Foundation is named after thorium advocate Alvin Weinberg, research director of Oak Ridge National Laboratory (ORNL), which produced plutonium for the Manhattan Project.

Weinberg Foundation’s headquarters are at Somerset House on London’s Strand. In keeping with thorium’s image as a ‘green’ nuclear energy source, its patron is Baroness Bryony Worthington, founder of emissions trading lobby group Sandbag and a key architect of the 2008 Climate Change Act.

The Foundation’s CEO Laurence O’Hagan is under no illusions about the scale of the challenge of taking on a uranium fuel cycle industry worth an estimated £200bn a year. “The argument is it will take too long,” he says. “That the established nuclear industry doesn’t want to change. But if we don’t start now, we’ll never get there. The potential advantages are so significant that we believe they are worth pursuing.”

O’Hagan sees considerable promise in molten salt reactors (MSR). Indeed, one of Alvin Weinberg’s major projects at Oak Ridge was the Molten Salt Reactor Experiment of 1965-1969, a 7.4 MW thorium-based demonstration reactor using U-233 as the main fissile driver.

Unlike conventional nuclear reactors which use solid fuel, usually rods or pellets, MSRs use a mixture of fluoride salts in a molten state. The salt mixture includes fissile material, i.e. fissile isotopes of uranium and/or plutonium, together with fertile material, such as T232 or U238.

The front-running thorium-based MSR is the liquid fluoride thorium reactor (LFSR). In this design, the molten salt also serves as the primary coolant, carrying heat away from the reactor, and delivering it to a secondary cooling circuit and ultimately to the steam turbines that generate electricity.

One of the main advantages is the reactor and its cooling circuits operate at near atmospheric pressure, reducing the chance of any explosion. As fuel in a LFTR is already in liquid form, it cannot melt down, as can solid fuel rods in a LWR.

Furthermore, the LFTR’s large negative temperature coefficient means that regulation of the reactor’s temperature is passive, so there is no need for control rods. The molten salt expands as a result of the heat generated by fission, which slows the rate of fission.

The reduction in fission heat cools the salt, which in turn leads to an increase in the rate of fission. In other words, as the reactor temperature rises, the reactivity decreases. The reactor thus automatically reduces its activity if it overheats.

In the event of a reactor overheating, the fuel and salt drains into a holding tank, where the fuel spreads out enough for the reactions to stop. The salt then cools and solidifies, encapsulating the radioactive materials.

Another major advantage over uranium is fuel efficiency. Due to the degrading effect of neutron bombardment on solid fuel rod metal cladding in LWRs, between only 2-4% of the energy contained within can be used before they have to be removed.  An LFTR reactor, however, would continuously recirculate nuclear fuel, thus greatly improving efficiency and radically diminishing the produced volume of nuclear waste and proliferation risk.

Corrosion: The killer blow?

On paper at least, LFTRs are highly attractive and it is easy to see why they have a growing number of proponents. In practice, however, there are major drawbacks yet to be overcome.

While Weinberg’s work at Oak Ridge’s relatively short-lived Molten Salt Reactor Experiment successfully demonstrated the potential for thorium molten salt reactors, a number of serious problems were highlighted, particularly pertinent for power generation reactors with an operational lifetime of several decades.

Researchers at Oak Ridge found that the Hastelloy-N metal used for the containing molten salts cracked and corroded under intense radiation.  The development of corrosion-resistant materials capable of surviving exposure to neutron bombardment and fluoride salts at high temperatures for decades is essential if LFTRs are ever to be a commercial proposition.

“Corrosion was one of the problems at Oak Ridge but since then material science has considerably progressed,” says O’Hagan. “We are now two generations beyond Hastelloy.

“MIT is researching using salt as a coolant and they are about to patent a corrosion-resistant material. We are not claiming all the engineering problems have been solved and there has to be work done to resolve them, but all the signs are pointing in the right direction.”

The main stumbling block, though, is economics. “LFTRs are theoretically beautiful but making it work in practice is a different matter,” says Johann Lindner, who heads up Excel’s European division. “In the end, they will not get off the ground because building a full-size unit will prove to be economically unviable,” he says.

“Building an LFTR requires more than just a reactor design. It requires a new fuel cycle with fuel fabrication facilities, remote handling equipment, and new back-end spent fuel management methods and technologies.

“It’s a non-starter; Darwinian selection has chosen LWRs. There may be some prototypes built but you’ll never convince utilities to buy them for commercial power generation. The first 50-100 will be too expensive compared to LWRs.”

Thorium fuel has so far been used in about 30 operational reactors. Most of these were located in the USA, Germany, Netherlands and India. A single example operated in the UK, from 1965 to 1976: the Dragon Reactor at Winfrith, a helium-cooled test reactor.

Aside from Oak Ridge, perhaps the most significant use of thorium was the German THTR-300 (Thorium High Temperature Reactor), a 300 MW pebble bed modular reactor, which used a mixture of thorium and highly enriched uranium, between 1983 and 1989. The plant, constructed in the North Rhine Westphalia town of Hamm-Uentrop by Hochtemperatur-Kernkraftwerk, was not a success.

On 4 May 1986, within just six months of generating grid-connected power and days after the Chernobyl accident, the THTR-300, which had no containment building, was found to have released radioactive dust into the environment due to an erroneously open valve. It was later found that pebble friction had generated so much dust that several pebbles became jammed, and the attempts to unclog the blockage merely aggravated the release.

Thorium in the UK

Keith Perron, a former nuclear submarine reactor specialist at Rolls-Royce, believes the only viable usage of thorium in the UK is its use in existing LWRs rectors or to incinerate plutonium as a final disposal route as an alternative to the type of MOX reprocessing plants as developed at Sellafield.

“Uranium MOX fuel designs, whereby plutonium is mixed with uranium oxide, do not remove plutonium, they just recycle it,” he says. “Such fuel actually produces more plutonium than it started with. Judged as a means to incinerate separated plutonium and to rid it from the world, MOX is a dismal failure.”

The traditional problem with uranium MOX is chemical changes within the fuel rod result in a positive feedback coefficient, i.e. radioactivity increases over time. By mixing thorium with plutonium oxide, so-called ‘THROX’ would not react that way, it stays negative, which means in theory you could continuously recycle and reprocess the fuel rods until the actinides have been burnt up, says Perron.

Again, however, the medium-term prospect for thorium usage in conventional reactors is extremely poor, although a company called Thor Energy, a division of Scatec, has made an experimental thorium fuel rod to be loaded into a test reactor in Norway this year.

Current development of molten salt reactors

The only operational reactors using thorium currently are in India, which possesses abundant thorium reserves but little uranium. These are conventional, solid fuel LWR reactors.

It is expected China will be the first nation to develop a new MSR. The China Academy of Sciences in January 2011 launched a $350 million R&D programme on LFTR, known locally as the thorium-breeding molten-salt reactor (TMSR).

The 2 MW test unit, developed by the Shanghai Institute of Nuclear Applied Physics, is currently expected to be operational by 2020. However, the programme has been delayed by two years as it is taking longer than expected to train the 700 scientists required, says O’Hagan.

India is also slowly developing a thorium programme at its Bhabha Atomic Research Centre in Mumbai, although primarily for usage in an advanced heavy water reactor rather than MSRs. Meanwhile, Russia is believed to be developing thorium as part of a generic nuclear research programme.

Reborn in the USA?

The USA does not have a concerted thorium programme at present, although there are interesting developments in Cambridge, Massachusetts, home to Transatomic Power. An offshoot of MIT, Transatomic Power is developing the WAMSR (Waste-Annihilating Molten Salt Reactor) designed to run not on thorium, but on the United States’ considerable stockpile of radioactive waste.

The company’s ultimate aim is to produce a 500 MW unit. It estimates that it can build such a plant for $1.7 billion, roughly half the cost per megawatt of current LWRs.

Transatomic Power, backed by the founder of E Ink, Russ Wilcox, appears to be serious. It has recruited highly experienced nuclear engineers from Westinghouse and MIT scientists and it recently scooped the top award at the Department of Energy’s 2013 Energy Innovation Summit.

So far, it has raised a fraction of the $200 million needed to build a small prototype. Aside from materials science, the lack of funding – from both the private and public sectors – is likely to continue to thwart ambition for thorium.

Steve Kidd, Deputy Director General of the World Nuclear Association, cannot foresee a bright future for thorium. “It’s only when the likes of Westinghouse, GE Hitachi and Areva come into the frame will thorium get going,” he says.

“Most of the current development is by physicists and other scientists at government research centres and they are not too fussed about commercial development. It may be so that the thorium cycle is superior to uranium and using thorium in reactors is perfectly technically feasible but nobody is going to commercialise it because in the 1950s we decided to go down the uranium route.”

The Weinberg Foundation refuses to be downhearted in the face of cynics in the conventional nuclear industry. “In my opinion, a commercial MSR is quite likely within 20 years,” says researcher David Martin. “There are many reasons for this, firstly the economics of the current nuclear industry. They don’t have a product they can build on time and to budget.

An MSR is basically a chemical set with some surrounding concrete, and it operates at atmospheric pressure so there’s no need for multiple redundant safety systems and high-pressure vessels.  In theory, the key components of MSRs could be constructed in a modular fashion, rather than built in situ on a bespoke basis.

“Furthermore, fuel fabrication is more chemistry than physics. It’s far easier to manufacture the few cubic metres of fluoride or chloride salts than fabricate fuel rods. Given the safety of operation I just can’t see how it could be more expensive than light water reactors.”

Martin thinks it is high time the Government put its hand in its pocket to fund more research. “There should be a vigorous programme in order to recapture some of the optimism that characterised the first wave of nuclear reactors. In the UK, nuclear R&D is a mess. The fragmentation of the industry was an act of vandalism which has left us without a nuclear research base.”

Had there been 60 years of development of molten salt reactors, the nuclear industry may have been in a very different position. Given the prevalence of the uranium fuel cycle, however, only an optimist could believe that the world will give thorium a second chance.
