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 green hydrogen plant commissioning by 2030.

‘Hydrogen Production Costs 2021’, published by the Department for Business, Energy and Industrial Strategy in August 2021, sets out the levelised cost, based on commissioning year, of various hydrogen production technologies. The information requested can be found in the table ‘Technical and cost assumptions (2020 real prices) within the annex to the report. The capital expenditure associated with a 1GW electrolytic plant commissioning in 2030 ranges from £433 million to £1,708 million depending on the technology. Please see:

We will continue to monitor and update cost estimates based on new evidence as it becomes available.
