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 impact of the production of hydrogen on CO2 levels.

The Government's Net Zero Strategy sets out how low carbon hydrogen will be an essential part of our future energy mix. We are currently consulting on a new UK standard for low carbon hydrogen, which will ensure any hydrogen production we support provides genuine carbon savings. As part of this we have published a comprehensive assessment on the lifecycle greenhouse gas emissions of different production methods.

The UK Hydrogen Strategy indicates that use of 5 GW low carbon hydrogen could deliver total emissions savings of 41 MtCO2e between 2023 and 2032, the equivalent of the carbon captured by 700 million trees over the same period.
