Nuclear is a great way of producing hydrogen as it generates huge amounts of reliable, low-carbon energy. Nuclear and hydrogen are also two clean technologies that can help us make big reductions in carbon emissions. While both technologies are vital on their own, at Sizewell C we have an exciting vision to bring them together.
Nuclear generates always-on, low-carbon power and for years has provided around 20% of the UK’s electricity. Hydrogen only produces water when it burns and has great potential as a clean fuel for transport, industry, and home heating.
Nuclear and hydrogen are both big priorities for the Government. They were included in the Ten Point Plan for a Green Industrial Revolution and the 2020 Energy White Paper.
One of the best ways of producing hydrogen is by splitting water molecules using an electrolyser. Using low-carbon nuclear energy to power the electrolyser means we can produce hydrogen which has no carbon emissions.
At Sizewell C, we are exploring how we can produce and use hydrogen in several ways.
Firstly, it could help lower emissions during construction of the power station. Secondly, once Sizewell C is operational, we hope to use some of the heat it generates (alongside electricity) to make hydrogen more efficiently.
Sizewell C is already set to be one of the biggest Net Zero projects in the UK. Linking it to other low-carbon technologies can bring even more flexibility and value to the energy system. Our plans could support the local economy and stimulate a low-carbon hydrogen and direct air capture market in the East of England.
Once operational, Sizewell C could produce hydrogen for a variety of uses including:
