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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment he has made of the potential effect of blending hydrogen with natural gas in the gas grid on (a) carbon emissions from domestic heating and (b) consumer prices.

BEIS officials are working with industry to understand the potential for blending hydrogen with natural gas in the grid. This work includes investigating the range of carbon emissions that could be saved in different blending scenarios, depending on the scale of blending and source of hydrogen.

BEIS officials will be working closely with Ofgem and industry to explore the potential for a future billing methodology – that fairly considers hydrogen blends whilst protecting consumers. Any GB-wide changes will depend on hydrogen blending being proven safe and affordable.

We do not expect an impact on consumer bills when trialling hydrogen blending in the gas grid.
