And finally, ideally, the last 20% shifts to gas turbines fueled with clean hydrogen.
The UK has about 1000 TWh of hydrogen storage potential in onshore salt deposits that could be solution-mined to make underground hydrogen storage caverns.

Siemens is providing a gas turbine generator that will run on 100% renewable hydrogen as part of the HYFLEXPOWER demonstrator project:

Siemens and General Electric both have roadmaps for gas turbines running on pure hydrogen:

Most current turbine models are already capable of running on a methane-hydrogen blend.
I like to highlight these projects because people sometimes mistakenly think that seasonal-scale storage with hydrogen also requires breakthroughs in scaling fuel cell technology. Evolutionary developments in gas turbine technology will also make it practical.
- cbmuser 6y agoThe UK has opted for nuclear. They are building and planning in Bradwell, Hinkley Point and Sizewell.
- philipkglass 6y agoGiven the high costs of Hinkley Point C, I suspect that the new reactors planned for Sizewell and Bradwell may not actually be built. "Hinkley Point C nuclear plant to run £2.9bn over budget" https://www.bbc.com/news/business-49823305 https://www.bbc.com/news/business-49823305 French power company EDF said the new nuclear plant it is building at Hinkley Point C will cost up to £2.9bn more than thought. It raised its estimate for the project, in Somerset, to between £21.5bn and £22.5bn, blaming "challenging ground conditions". It also said the risk of the project being 15 months late had risen. ... These cost overruns will not hit UK consumers. However, a new way of paying for further nuclear stations, such as Sizewell, is being considered. Under this new model, consumers would see costs of construction added to their bills as the project went along. It means that customers could be exposed to cost overruns. That is why today's announcement is important and why EDF will find it harder to make the argument for building Sizewell.
