Nowadays, the idea of using hydrogen as a renewable energy source is growing. Among its different origins, green hydrogen, obtained from surplus energy from renewable sources, stands out. To make efficient use of the energy transformed into hydrogen, it must be stored in some way. Underground storage of hydrogen is becoming a feasible option compared to the use of above-ground metal tanks, due to the permeability problems of metal structures in relation to hydrogen. One of the possible alternatives is the conditioning and creation of salt caverns since the low permeability of halite (salt rock) allows hydrogen to be efficiently confined without leaks. This study attempts to test the feasibility of this type of storage, focusing on short-term operating cycles, 30 years of useful life.
