Numerical study on salt cavern behaviors of bedded rock salt for hydrogen storage [PDF]
The underground hydrogen storage (UHS) in bedded rock salt faces three challenges: (1) the stability and usability of cavern related to rock salt creep behavior; (2) the sealing ability of salt cavern related to preventing H2 penetration; (3) the H2 ...
