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 less polluted planet. The tremendous and increasing demands necessitate finding large-scale storage techniques. Underground salt caverns seem to be promising. Nevertheless, fast solicitations (thermal mechanical) of these caverns, reply demands, imply damage ambient rock salt. There general scientific ambiguity about transport mechanisms taking place intact/damaged, particularly for hydrogen. In this paper we provide detailed review while cavern undergoes cycling. This helped us define mathematical approach simulate hydrogen migration around underground caverns. We ended up by presenting patent laboratory setup that are currently using any required model parameters experimentally.
