Question to the Department for Energy Security & Net Zero:
To ask His Majesty's Government what technical assessment they have made of the potential level of hydrogen blending with natural gas in the National Transmission System.
The GB transmission system operator (National Gas) has conducted trials on the safety of hydrogen blends of up to 2%, 5% and 20% by volume in the National Transmission System. The Department is working with the Health and Safety Executive to ensure that this evidence is assessed as efficiently as possible.
We intend to publish a consultation on blending hydrogen into the GB gas transmission network in the near future.
