... Natural, bedded salt formations can be considered as host rocks for cavern storage of hydrogen produced by the conversion of excess energy to hydrogen via electrolysis. There are three active facilities in the US and one facility in the UK stores hydrogen in salt caverns (Zivar et al., 2021). Thick salt...
