The greenhouse gas emissions associated with different hydrogen production methods depend on a wide range of factors such as the feedstock energy, the efficiency of the hydrogen production plant and the CO2 capture rate for carbon capture utilisation and storage (CCUS) enabled blue hydrogen production.

BEIS is working with industry, academia and regulators on understanding and comparing options for an emissions standard that will define low carbon hydrogen. As part of this work, we have been assessing emissions associated with a range of hydrogen production methods, including CCUS enabled blue hydrogen and electrolytic green hydrogen.

We will be releasing further detail on this work in the coming months and intend to consult on a UK Low Carbon Hydrogen Standard alongside the UK Hydrogen Strategy.
