A discussion on hydrogen migration in rock salt for tight underground storage with an insight into a laboratory setup

Hydrogen is being regarded as a primary vector in the energy transition process towards a less polluted planet. The tremendous and increasing energy demands necessitate finding large-scale storage techniques. Underground salt caverns seem to be promising. Nevertheless, the fast solicitations (thermal and mechanical) of these caverns, to reply to the fast demands, imply damage to the ambient rock salt. There is a general scientific ambiguity...
