Implication

Preliminary experiments uncover minor mineral changes in rock salt exposed to hydrogen, suggesting stability in underground hydrogen storage applications.

Key Points

Mineralogical stability of rock salt was observed after hydrogen exposure, indicating potential for UHS.
Laboratory conditions of 10 MPa and 60 °C revealed localized halite recrystallization but no significant changes.
Controlled experiments conducted using samples from Eocene Barbastro Formation enhance understanding of hydrogen–rock interactions.
Findings suggest the effectiveness of salt caverns as a reliable medium for underground hydrogen storage.
