The Energy Technologies Institute (ETI) has launched a new project into examining the potential for storing hydrogen (H2) and its gas mixtures in salt caverns.
The ‘Salt Cavern Appraisal for Hydrogen and Gas Storage’ project builds on earlier ETI work, which demonstrated that storing H2 in salt caverns could provide a significant contribution to decarbonising the UK’s future electricity grid.
The previous ETI report, written last year, showed how a single H2 cavern could cater for the peak energy demands and fluctuations of an entire UK city. It also detailed how using these already-existing caves could reduce the investment needed for a new clean power station capacity.
This project will provide more detail on the suitability of individual caverns and the costs associated with using them, increasing the evidence base needed if they are to be developed further
The latest ETI project will examine the potential of three existing salt caverns in Cheshire, Teesside and East Yorkshire, which could be used to store H2 for power generation.
