Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what recent estimate she has made of the mass of hydrogen required to be burned in a hydrogen-fired power plant to generate 1GWh of electricity.

Figures published by the Department for Business, Energy and Industrial Strategy in the June 2022 Hydrogen Readiness Report suggest that an 800MWh hydrogen-fired power plant would require 50 tonnes of hydrogen fuel per hour. Therefore, a 1GWh plant could be expected to require 62.5 tonnes of hydrogen.
