Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, what plans she has to amend the Gas Safety Management Regulations to allow hydrogen blending within the main grid to levels higher than 0.1 per cent by volume; and if she will make a statement.

The Health and Safety Executive’s (HSE's) review of the Gas Safety (Management) Regulations 1996 (GSMR) is ongoing. The review is considering potential changes in gas quality, and policy options to enable future changes to the gas quality specification (currently set out in Schedule 3 of GSMR) to be made in an efficient way. This will enable safe hydrogen blending and wider safe use of hydrogen in place of natural gas. Following completion of the review, any proposals for change and associated policy options HSE puts forward will be considered.
