Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment she has made of the potential merits of increased geological hydrogen production in the UK.

DESNZ commissioned research from the British Geological Survey to understand the potential for natural hydrogen reserves in the UK. This research was published in 2025 and provides a high level, national scale geological map-based assessment of the UK, identifying areas more and less likely to contain natural hydrogen resources. We are considering further research to build our understanding.

The department is also actively monitoring developments in other countries via our membership of the IEA’s Hydrogen Technology Collaboration Programme. Our teams liaise regularly with academics and experts to make sure the government is well-sighted on emerging technologies, evidence and activities in the UK and internationally.
