Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what steps they are taking to promote the use of green hydrogen as an energy source.

Hydrogen Allocation Rounds (HARs) remains our primary mechanism for allocating revenue support through the Hydrogen Production Business Model to low carbon, non-CCUS enabled hydrogen production facilities across the UK.

In the Autumn 2024 Budget, we confirmed support for 11 green hydrogen projects from the first Hydrogen Allocation Round (HAR1), and on 7 April 2025 we announced a shortlist of 27 projects that were invited to the next stage of the Second Hydrogen Allocation Round (HAR2) process.

This announcement reinforces the Government’s recognition of the key role low carbon hydrogen will play in delivering our Clean Energy Superpower and Growth Missions.
