Question to the Department for Business, Energy and Industrial Strategy:

To ask Her Majesty's Government what assessment they have made of the possible use of hydrogen alongside existing gas boilers; and whether the use of hydrogen could remove the need for gas boilers entirely.

The Government is monitoring progress on trials that use blends of hydrogen in existing gas boilers to inform decisions in 2023 on whether to enable blending up to 20% hydrogen by volume into Great Britain gas networks. The Government is also supporting research, development and testing projects that will generate evidence on the costs, feasibility and impacts of using boilers that run entirely on hydrogen.
