The industrial process currently used to produce hydrogen, because of its reducing power, is intended for the oil refining industry, the chemical industry and the production of certain materials.

This is the first priority of the "national strategy for the development of decarbonized hydrogen in France", now the "national low-carbon strategy", decided by the government in 2020
