C Stokel-Walker, The challenge of storing hydrogen in salt caverns, Professional Engineering, Issue 1 2026, p 3

In UK, hydrogen is recognised as a potential alternative fuel, with  an international usage approaching 100 million tonnes annually, but with challenges of storage and handling.   One viable solution to the former is the adaptation of spent salt caverns.  Cavern-storage of hydrogen started in UK in the 1980s, and projects are appearing in Cheshire, South Dorset and East Yorkshire.   Two of the challenges to be overcome are the tendency of hydrogen to react with natural rock material in the cavern walls, and the steels used in borehole casings and compressors.
