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

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment his Department has made of the potential to produce and use (a) green hydrogen and (b) blue hydrogen from 2021 to 2024.

The UK is aiming for 5GW of low carbon hydrogen production capacity by 2030 for use across the economy, and we expect this to come from a combination of green and blue hydrogen production methods. The UK currently produces around 10 – 27TWh of hydrogen, most of which is not low carbon (‘grey’) for use in the petrochemical sector.

Production of large-scale blue hydrogen requires the necessary carbon capture and storage infrastructure to be in place, so we do not expect this to come forwards until the mid-2020s. The majority of low carbon hydrogen production during 2021 – 2024 is therefore likely to be green hydrogen, with end use focussed on sectors with existing demand such as transport and industry, with use in heat and power developing over time. To achieve our legally binding net zero commitments we will also need a complete switch to low carbon production, as addressed in our recent Industrial Decarbonisation Strategy.

Further details on how we will scale up production of low carbon hydrogen through the 2020s, as well as decarbonise existing grey hydrogen production, will be set out in the UK Hydrogen Strategy, which will be published in the coming months alongside further detail on the Net Zero Hydrogen Fund and business models to support hydrogen and industrial decarbonisation.
