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 mass of hydrogen that would be produced per running hour by a 1GW blue hydrogen plant.

A 1GW[1] blue hydrogen production plant running for 1 hour at full capacity would produce 1GWh of hydrogen, equivalent to 25.4 tons.

[1] Rated as 1GW on the basis that the hydrogen it produces will be used for combustion and the latent heat of vaporisation of water is recovered
