4 - Underground and pipeline hydrogen storage

Abstract

The development of renewable wind and solar energy, which is by nature intermittent, has lead to solutions being developed for the storage of excess electricity. One technical solution is the possibility of producing hydrogen through the electrolysis of water. In such a scheme, storing the hydrogen is equivalent to storing electricity, which could be used for fuel cells. In the main cycle of hydrogen production–storage–use, geological storage is a fundamental element.
