Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he made of the potential merits of the use of hydrogen for seasonal energy storage.

Hydrogen’s ability to store energy for long periods of time and in large quantities is central to its strategic value to a fully decarbonised energy system and the Government envisages hydrogen storage being a key part of future network infrastructure.

Stored hydrogen could cover seasonal lulls in wind or solar generation; offer a flexible fuel source in power generation and provide an alternative to natural gas; heating our homes and workplaces. External analysis showed that long duration energy storage, supplied primarily by hydrogen, could provide between £13 billion and £24 billion in savings to the electricity system between 2030 and 2050.
