From: Characterization and assessment of hydrogen leakage mechanisms in salt caverns
H2 storage in the base model over 5 years of cyclic storage: (a) pressure in the salt cavern, (b) pressure in the surrounding formation 25 m away from the salt cavern wall, and (c) H2 flow rate between the salt cavern and formation (positive values indicate flow of H2 from the salt cavern into the formation, and negative values indicate the flowback).
