As we saw in the last post plans for a new nuclear power station at Hinkley Point C, Somerset have been beset by troubles. This next post aims to detail further problems with a nuclear strategy for the UK, and highlight the alternatives to achieve a genuine low-carbon energy sector.
Hinkley Point C (henceforth just Hinkley) is simply another example of the current UK government engaging with projects not for economic or environmental concerns, but for ideological reasons. For example, “taxpayers could end up paying more than £30bn through a range of subsidies” in order to support the new power station because it is not profitable by itself (Business Leader, 2016). Advisors in DECC (when it existed) also had links to EDF, which could explain the preferential treatment given to nuclear energy (Clarke, 2016) despite the fact that the current set price for electricity generated from the power station offered by the UK government is double average wholesale electricity prices (Elmes, 2016), representing another loss for the average UK citizen. As if that wasn’t enough,
“The predicted cost of Hinkley Point C has steadily risen from £14bn to £24.5bn and has steadily risen from earlier estimates of £16bn. The complexity of the project is enormous, due to what is believed to be by many to be an over-engineered design. There are also reported issues regarding the manufacture of the reactor pressure vessel for the EPR [European Pressurised Reactor] associated with anomalies in the composition of the steel.” (Freer, 2015)
These defects – enormously dangerous in a nuclear power station – are down to the French nuclear firm Areva, responsible for leading the construction of Hinkley, misreporting or failing to report key information in their quality control documents. As a result Hinkley – and other nuclear power plants around the world – may be using components that would be unable to “withstand sudden breakdown in certain conditions” (Boren, 2016).
On the bright side, we won’t have to worry about these manufacturing errors causing problems in the immediate future. Due to ongoing delays “Hinkley C is unlikely to produce electricity much before 2030” (Carrington, 2016a). By the time it is online it is likely to face ongoing problems due to extreme weather events caused by climate change (if global warming hasn’t been mitigated appropriately by then). Nuclear power stations are particularly vulnerable to extreme weather as these events
“could disrupt the functioning of critical equipment and processes that are indispensable to safe operation including reactor vessels, cooling equipment, control instruments and back-up generators.” (World Energy Council, 2014)
So at the moment we are looking forward to a nuclear power station billions over budget, not scaled to be completed until 2025 (Farrell, 2016), and subsequently vulnerable to storm damage and rising sea levels.
On top of this the justification that Hinkley will provide the UK with “baseload”power that is “vital to the UK” (EDF, 2016) is a myth. The importance of the new power station “has been repeatedly overplayed” (Gosden, 2016) and “the idea of large power stations [nuclear or not] for baseload is outdated” (Beckman, 2015). Practical experience, such as the German states of Mecklenburg-Vorpommern and Schleswig-Holstein running on 100% renewable energy, and a host of studies and computer simulations of electricity markets and supply-demand systems prove that monolithic power stations providing baseload power are not required (Diesendorf, 2016). Other studies have shown that closing down nuclear power stations and transitioning to renewable energy provides a host of environmental and economic benefits without jeopardising energy security (Phys.org, 2012; Gawel & Strunz, 2014).
Additionally, any employment supported by the construction of Hinkley will be temporary and filled by overseas workers, and less than a thousand jobs will be “created” for day-to-day operations (Fairlie, 2016). Jobs in the renewable energy sector far outweigh nuclear jobs. It is no surprise then that public support for Hinkley is very low (Chrisafis, 2016; Pagnamenta, 2016). There are even internal disputes within the board of EDF, with worker representatives filing “a challenge to overturn the company’s controversial decision to build the nuclear reactors” due to essential information about the power station not being shared with all board members (Chrisafis, 2016).
So we have seen that nuclear energy would be problematic for UK, and if Hinkley Point C were allowed to develop it would be a tacit endorsement for further nuclear development regardless of its practicality. So what are the alternatives?
The current situation seems dire. At the moment “the percentage of energy Britain now has to import has returned to the levels last seen in the early 1970s, before North Sea oil came on stream” (Elliott, 2016). This is a fear that the nuclear industry has exploited in order to appear as a solution. But as Elliott continues, “the cost of renewables are coming down all the time”. To develop a practical, secure energy supply requires the UK “to move away from large Hinkley-type projects” (Business Leader, 2016). This is not only an environmentally safer option but more economically secure – the thinktank Intergenerational Foundation found that “Britain would pay up to £40bn less for renewable alternatives that would generate the equivalent power to Hinkley over the plant’s planned lifetime” (Vaughan, 2016a). For the UK to pursue nuclear energy when “the world is finally producing renewable energy at an industrial scale” and with global installations of renewable energy projects surpassing “100,000 megawatts of capacity” in 2014 seems ludicrous (Steiner, 2015). As The Economist (2016) reports,
“Since Hinkley became a serious proposal less than a decade ago, the cost of nuclear power has increased, that of renewables has fallen and the price of battery storage—which could one day disrupt the entire power system—has plummeted. What is more, EDF’s nuclear technology has failed to get off the ground in the two projects in Finland and France that have sought to use it.”
So what are our options? Let us assess the evidence.
The world’s largest offshore windfarm was recently approved by the UK government, set to be constructed 100km off the Yorkshire coast (Anthony, 2016). It will provide power to almost two million homes when completed. As more of these windfarms are constructed (there are currently thirty offshore windfarms in UK territory) the energy generated will steadily become more reliable – as den Rooijen (2016) explains, “if the wind doesn’t blow in one [area], the wind blows in another, and the net effect is that the combined power output is less variable”. He continues
“At present, we have 2,200 wind turbines in operation and under construction, taking up less than 1% of our total seabed. National Grid estimates that nearly half of all power could be generated from our seabed by 2030 through offshore wind, combined with tidal power lagoons and strong electrical connections to our neighbouring countries.”
With 5GW (gigawatts) of offshore wind energy and 9GW of onshore wind currently online with new projects constantly in the pipeline (e.g. Hornsea Projects 1, 2, and 3) the 3.2GW that Hinkley will provide seems insignificant by comparison (Macalister, 2016a).
At the moment offshore windfarms are already being built at cheaper prices than Hinkley, and will meet 10% of the UK’s electricity demand by 2020 (Sauven, 2016; Macalister, 2016b) while Hinkley will only produce 7% when it is finally built in 2025 (ignoring delays common with the reactor design – see Stacey & Burgis, 2016). Looking to land, the UK government’s own calculations predict that “onshore wind power and large-scale solar [will] cost less per megawatt hour than new nuclear by 2025” (Vaughan, 2016b). Renewables will also be cheaper to build – the Intergenerational Foundation found that onshore wind power would be £31.2 billion cheaper than Hinkley whilst producing the same amount of energy over a thirty-five year period (Simms, 2016).
In reality the UK has exploited less than 1% of its offshore wind energy potential – a total of 675GW is economically feasible, which is more than six times the UK’s current electricity demand (Cavazzi & Dutton, 2016). The potential for wind energy alone dwarfs UK nuclear power.
Solar power is similar to wind power – it is cheap, efficient, and a far better alternative to nuclear projects like Hinkley. By 2025, large-scale solar is expected to cost between £50 and £75 per megawatt hour, according to the UK government’s energy department, whereas nuclear power is expected to cost “around £85-125/MWh, in line with the guaranteed price of £92.50/MWh that the government has offered Hinkley’s developer, EDF” (Vaughan, 2016b). The Intergenerational Foundation’s report consolidates the cheapness of solar compared to nuclear, citing evidence that solar power in the UK would be £40 billion cheaper compared to Hinkley over the thirty-five year contract period (Simms, 2016).
Solar power is now 50% cheaper than it was in 2011, and “more than 800,000 homes now have rooftop solar” (Sauven, 2016) proving its effectiveness. Solar power recently beat coal power in the UK for the first time some months ago, generating “1,273 gigawatt hours of power” in May, beating the 778 gigawatt hours generated by coal (Evans, 2016), showcasing its ability to outclass fossil fuels in power generation.
Looking past simple economic comparisons, solar power arrays can also enhance biodiversity as they take up only a small percentage of the land and often allow insect species “to thrive” compared to arable land (Solarcentury, 2014). A more recent study found that “solar farms can lead to an increase in the diversity and abundance of broad leaved plants, grasses, butterflies, bumblebees and birds” (Montag et al., 2016). Solar power on agricultural land is also a possibility – a 2013 study published in Agricultural and Forest Meteorology found that crops under a “half-density” array of solar panels “were just as productive as the ones in the unshaded control plots; in a few cases, they were even more productive”and that “shading irrigated vegetable crops with PVPs [photovoltaic panels] allowed a saving of 14 percent to 29 percent of evapotranspired water, depending on the level of shade created and the crop grown” (Marrou et al., 2013). Solar power is thus an effective energy delivery strategy without having to sacrifice grassland or arable land, compared to the large footprint required of nuclear power stations like Hinkley.
Solar and wind power are not the only alternatives to Hinkley available to us – there is a miscellany of other technologies available. Wave energy devices, for example, placed in the “most economic areas” around the UK’s coast could generate up to 10GW, which equates to “11% of the UK’s current power generation” (Carbon Trust, 2012).
Instead of producing additional power, increased energy efficiency measures in the UK would make projects like Hinkley obsolete. Improving efficiency could, according to various authors, reduce electricity demand by the equivalent of four to six Hinkley power stations (DECC, 2012; Blackman, 2016) and save billions of pounds a year. As Damian Carrington (2016b) writes,
“Energy efficiency could deliver six Hinkley’s worth of electricity by 2030, interconnector cables to Norway, Denmark and France could add another two or three Hinkleys to the grid by 2025 and four Hinkleys’ worth of electricity could be saved by 2030 by increasing the ability to store electricity and making the grid smarter, with the latter alone saving bill payers £8bn a year.”
These trends in efficiency, smart grids, and better energy storage won’t go away – “the National Grid predicts that in some scenarios by 2020, small-scale and distributed generation will represent a third of total capacity in the UK” (Sauven, 2016). This is simply proof that the age of megaprojects like Hinkley is over – the UK needs to focus on connecting “consumption as well as supply and think more decentralised than central” (Elmes, 2016).
Is it Possible?
These technics are far from implausible – many of them rely on technology that exists today and trends that are already occurring. If Hinkley Point C is cancelled (and it should be) additional renewable energy projects can “plug significant gaps in capacity very quickly – much more quickly than long lead time and significantly delayed new nuclear” (Caldecott, 2016). The recent analysis from the Energy and Climate Intelligence Unit using “ultra-conservative” estimates and considering “only mature technologies” succinctly surmised that “Hinkley is not essential” (ECIU, 2016), contrary to the assertions of the EDF chief executive (de Rivaz, 2016).
As Gawel and Strunz (2014) wrote in their case study of Germany’s nuclear phase-out, it is less about technology and more about providing a “a long-term transition perspective and a stable political consensus” that will encourage the development of renewable energy and not so-called “low-carbon” energy sources like nuclear or gas. This social and political shift will readily yield “measurable economic and environmental benefits” (Phys.org, 2012).
Many studies and analyses looking at the possibility of a long-term, global shift to renewable energy have found that it is plausible and easily achievable. EDF’s claim that we shouldn’t “hope that a new technology will meet all our needs” is unfounded and false – we don’t need “new” technologies because existing ones are more than enough (de Rivaz, 2016). Such claims muddy the waters when it comes to discussing a sustainable future and betray the wants of large energy corporations like EDF who are threatened by the coming wave of renewable and decentralised energy technologies. In fact, pursuing the idea of nuclear power as part of the UK’s energy strategy would be harmful to genuine renewable energy uptake – a study by the University of Sussex found that countries like the UK who are “nuclear-committed” and plan to replace old nuclear power plants with newer models are slower to adopt renewable energy and reduce the carbon intensity of energy generation (Lawrence et al., 2016; Cuff, 2016). The study identified that
“progress in both carbon emissions reduction and in adoption of renewables appears to be inversely related to the strength of continuing nuclear commitments.”
Thus any and all assertions that nuclear power should be a component of the UK’s energy strategy are detrimental in the long-term.
Jacobson and Delucchi (2010) in a peer-reviewed study found that instituting a global infrastructure based on wind, water, and solar energy could not only meet the world’s energy needs but reduce “world power demand by 30%”. In a growing trend, they emphasise that “barriers to the plan are primarily social and political, not technological or economic”. Schwartzman and Schwartzman’s (2011) similar study, published via the Institute for Policy Research & Development, found that a global transition to (only) wind and solar power could
“occur in two or three decades and requires very little fossil fuel (on the order of one half of a year’s present global consumption) and no revolutionary technological innovations.”
As far back as 2004 one peer-reviewed study identified that “humanity already possesses the fundamental scientific, technical, and industrial know-how to solve the carbon and climate problem for the next half-century” (Pacala and Socolow, 2004).
Importantly though, we cannot wait for these energy trends to unfold by themselves. Many political and economic actors will work and lobby to ensure that energy systems in the UK remain centralised and based on scarce supplies of fossil fuels, the better to control energy distribution in a country gripped by the worst inequality in decades (Williams-Grut, 2015; Reuben, 2015). But as Podobnik (2010) warned
“The historical record shows very clearly that deep, enduring changes in energy industries require the mobilization of mass social movements. We cannot simply wait for visionary politicians to forge the way.”
A mass social movement in the UK calling for fair, equitable, renewable energy generation (e.g. plasmatelly, 2014) is thus required to not only break the trend of monolithic, centralised energy projects being built, but also to protect and defend the environment from the biocrisis (Institute for Experimental Freedom, 2009). Projects like Hinkley Point C must be opposed whenever they emerge. Any form of society that hopes to survive in the coming decades can and must be powered by renewable energy.
