Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, how much hydrogen is produced in the UK each year by type; and what is the (a) CO2 footprint and (b) total tonnes of CO2 generated by the production of that Hydrogen in each year.

Current UK hydrogen production is mostly high carbon ‘grey’ hydrogen, including that produced as a by-product of another industrial process, with an estimated annual production of 21TWh. In these cases, emissions data held by Government is based on overall site emissions, so it is not possible to estimate the direct contribution of hydrogen production. Government is supporting industrial decarbonisation and new low carbon hydrogen production as part of the Net Zero Growth Plan, with around 4-5MW of electrolytic hydrogen already in operation. The UK’s Low Carbon Hydrogen Standard will ensure any production supported by Government meets strict emission thresholds.
