Government and industry back nuclear for green hydrogen future

18 February 2021

Nuclear power could produce one-third of the UK’s clean hydrogen needs by 2050, according to the Hydrogen Roadmap agreed by the Nuclear Industry Council (NIC) last week. The NIC, co-chaired by the Minister for Business, Energy and Clean Growth and the Chairman of the Nuclear Industry Association, sets strategic priorities for government-industry collaboration to promote nuclear power in the UK.

The NIC roadmap outlines how large-scale and small modular reactors (SMRs) can produce both the power and the heat necessary to produce emissions-free hydrogen, or “green hydrogen”. Nuclear stations also provide a constant, reliable supply of power that allows electrolysers to operate more efficiently, cutting production costs. Existing large-scale reactors could produce green hydrogen today at scale through electrolysis, as could the next generation of gigawatt-scale reactors. SMRs, the first unit of which could be deployed within the next ten years, would unlock further possibilities for green hydrogen production near industrial clusters.

Advanced Modular Reactors (AMRs) under development offer one of the most promising innovations for green hydrogen production, since they will create temperatures high enough to split water without diverting electricity. The ability to generate both power and hydrogen would cut costs further, add flexibility, and allow co-location of reactors with industry to aid further decarbonisation. The UK Government has targeted an AMR demonstrator by the early 2030s.

The roadmap estimates that 12-13 GW of nuclear reactors of all types could use electrolysis, steam electrolysis using waste heat and thermochemical water splitting to produce 75 TWh of green hydrogen by 2050.

The Climate Change Committee estimates that the UK could need up to 225 TWh of hydrogen per year to hit its net zero target. Rapid deployment of clean alternatives will be required, as the vast majority of the UK’s hydrogen is currently produced using fossil fuels.

The most common method, steam methane reformation, is low cost, but emits 10 kilograms of carbon dioxide for every one kilogram of hydrogen.

Since the main obstacle to green hydrogen is cost, the report identifies immediate steps to encourage nuclear-hydrogen development:

  • Funding for electrolyser research and grants to zero-carbon generators of all kinds, including nuclear, to install electrolysers.
  • Ambitious carbon pricing to make green hydrogen more competitive.
  • Five-year R&D AMR funding settlements to support the government’s target of a demonstrator by the early 2030s.
  • Inclusion of nuclear-produced hydrogen in the Net Zero Hydrogen Production Fund and the Renewable Fuels Transport Obligation.
  • Agreement of a new financing model to cut the cost of capital, for new nuclear projects, and thus the cost of electricity for hydrogen production.

Commenting on the report launch, Tom Greatrex, Chief Executive of the Nuclear Industry Association, said:

“Nuclear power should be right at the heart of green hydrogen production, alongside renewable technology. Nuclear reactors offer the innovative solutions we need to decarbonise sectors beyond electricity as part of a robust net zero mix, starting today and going into the future. We are pleased the government has recognised that potential, and look forward to working with them and other partners to create a strong framework for green hydrogen production.”

Julia Pyke, Director of Financing for Sizewell C, said:

“Green hydrogen from nuclear is not a distant dream but could happen now. Nuclear can offer continuous low carbon electricity to feed electrolysers alongside renewables. If Sizewell C gets the go-ahead, an electrolyser powered by Sizewell B could allow us to make fuel for H2 vehicles and plant for the construction, and it could kickstart a whole new hydrogen market in the East of England, including supporting Freeport East. In the longer term, Sizewell C could produce large amounts of green hydrogen and bring added flexibility to the energy system.”

Tom Samson, Interim Chief Executive of the UK SMR Consortium, said:

“It is exciting to see both Industry and Government embody climate leadership by acknowledging the important role that nuclear can and must play in generating clean green Hydrogen.  Our SMR technology can produce cost competitive green hydrogen and will play an increasingly important role in the clean energy transition for transport, heat and industrial sectors across the UK as well as creating enormous export opportunities to enable other countries to also benefit from a compelling SMR to Hydrogen solution.”

Boris Schucht, Chief Executive Officer of Urenco, said:

“I strongly feel that nuclear power perfectly complements energy generated from renewables in a net zero world and the uses of hydrogen for the decarbonisation of several sectors. These three technologies belong together and they are the future of energy systems. We are ready to play our part in this using our core competencies and leading technology in uranium enrichment and our investment in next generation technologies and fuels, collaborating with industry partners and Governments to realise nuclear energy’s valuable role in achieving net zero goals.”

Fiona Rayment, Chief Science and Technology Officer of the National Nuclear Laboratory, said:

“The transition to a net zero energy system is an exciting yet significant goal and none of us should underestimate the scale of the challenge. To enable the deep decarbonisation that is required, it is clear that hydrogen will need to play an ever-increasing role.

“Current and emerging nuclear technology has the flexibility to produce clean, reliable and cost-competitive energy to address the needs of our industries and markets, whether that is in electricity, heat or hydrogen. Nuclear generated ‘green’ hydrogen in particular, alongside other clean energy routes, will enable a plentiful supply to fuel our future economy.”

Notes to Editors

  • The Hydrogen Roadmap follows on from Forty by ’50: The Nuclear Roadmap, which set out a high-level ambition for the industry to produce 40% of the UK’s clean power by 2050, as well as make a substantial contribution to hydrogen production and heat decarbonisation.
  • The Nuclear Industry Council includes representatives of all parts of industry and government and was re-formed in 2017. More information on the NIC is available here.
  • Nuclear power has saved over 1 billion tonnes of carbon emissions in the UK over the lifetime of the industry, more than any other electricity source.
