Nuclear Energy (Financing) Bill — House of Lords, 2022-02-21
Topic: Energy
Daniel Mosley (Crossbench, Unknown): My Lords, I first declare my interests as an engineer and project director in the nuclear industry, working for Atkins. I welcome the Bill, and given that finance and costs dominated the £92.50 per megawatt hour strike price agreed for Hinkley C—approximately two-thirds of that price—it is clear that the proven RAB mechanism will be transformative in reducing the costs of new nuclear. It will reduce the weighted average cost of capital in new nuclear and, as the Minister said, bring a new range of investors, including pension funds and other institutional investors It is worth reiterating why we need new nuclear. I have taken part in many debates in my time in Parliament on the need for nuclear in our energy system. I have always been struck by how often the argument is reduced to nuclear versus renewables, so I would like to say a few words on the economic case for new nuclear, to counter what the noble Lord, Lord Teverson, said I started my career a long time ago, as a systems engineer, using systems thinking to design, integrate and manage complex systems. Applying that thinking to the energy system shows that we cannot consider elements of the system in isolation. For example, renewables are achieving competitive costs of power at the generator, in levelised cost of electricity—or LCOE—terms. But as the percentage of renewables on the system increases, so, too, does the cost of system modification and back-up to cover those periods of low renewable outputs. At high penetration, when there are high percentages of renewables on the system, the marginal cost of renewables, measured on a whole-system basis, will be far higher than the reported LCOE. We should therefore be comparing costs on a whole-system basis, rather than on a simplistic comparison of levelised costs of electricity between technologies, and investigating the system architecture that minimises the costs of electricity to the consumer. A multitude of studies confirms that having reliable firm power on the grid, such as that provided by nuclear, working together with renewables—that is the important point—makes the system cheaper. With the further cost reductions provided by the RAB model, not to mention fleet build, which, it must be emphasised, led to the great cost reductions that we have talked about in renewables, nuclear will be a vital part of the 2050 energy system The Bill is critical for the future of the energy system, helping to ensure that it is low carbon, secure and cost effective. But I suggest to the Minister an opportunity that could be taken with the Bill, involving another aspect of the net-zero system—hydrogen production, to build on what the noble Lord, Lord Whitty, mentioned. The Minister may recall that in July last year I asked him to consider whether hydrogen produced from nuclear energy should be eligible for the renewable transport fuel obligation, or RTFO, alongside other low-carbon sources. He replied that the Government’s aim was to remain technology neutral but that energy change to RTFO sources would require primary legislation. Now we have an ideal vehicle, in the shape of the Bill, to undertake this change. Now that we have left the EU, we are free to determine our own definitions for clean, non-emitting sources of energy. I am sure that the Minister would agree that the Government’s strategy should be technology-neutral across all sectors, and that opening policies such as the RTFO to a wider range of eligible solutions would create more resilience and cost-effective outcomes I know that there are ambitious plans to use the construction of Sizewell C as a world-leading example of UK hydrogen-powered construction, using hydrogen buses, diggers and other construction equipment. The early large-scale use of these vehicles will help drive down manufacturing costs and increase hydrogen demand, helping UK companies to get ahead and invest in long-term job creation. A simple change, adding nuclear-derived hydrogen to the list of zero-emissions sources defined by the Energy Act 2004, could unlock millions of pounds of private investment into hydrogen production in the UK and accelerate the Government’s hydrogen production targets, while also supporting the nuclear industry. I would welcome the Minister’s thoughts on this and look forward to discussing further with him and his officials Finally, I support what the noble Lord, Lord Rooker, said—although maybe without wishing for the return of the Central Electricity Generating Board. However, I mentioned the system architect. Who defines the overall system architecture? It is not clear at the moment who that is. I agree with the noble Lord that that is something to which the Government need to give serious thought.
