Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what her Department's latest estimate is of the capital expenditure cost of a new 1GW hydrogen-fired power plant commissioning by 2030.

Figures published by the Department for Energy Security and Net Zero in the Electricity generation costs 2023 report estimate that a 1.2 GW Combined Cycle Hydrogen Turbine (CCHTs) would cost £830million in 2025 to construct, falling to £740million by 2040.

Hydrogen to Power is an emerging technology and as such all figures are subject to change. We will continue to monitor and update cost estimates based on new evidence as it becomes available.
