Storing Hydrogen In… Caves?

A newly-launched £300,000 project is evaluating how hydrogen can shape the future of energy storage for the UK.

The Energy Technologies Institute (ETI) is partnering with engineering and construction company Foster Wheeler and the British Geological Survey to look into appropriate sites for storing hydrogen. Several salt caverns up to 25 miles off the coast are already being targeted.

“ETI modelling shows that flexible power generation systems comprising hydrogen generation with Carbon Capture and Storage (CCS), intermediate hydrogen storage – particularly using salt caverns – and flexible turbines are potentially attractive components in any future UK energy system,” said Andrew Green, programme manager of the ETI CCS.
