As the global energy transition to realize a carbon-neutral society is accelerating, hydrogen has come under the spotlight as a fuel, as well as the energy or feedstock for chemical synthesis and other industrial applications. Mitsubishi Heavy Industries, Ltd. is also working to develop various types of hydrogen production equipment. We are developing high-temperature steam electrolysis, which is the most efficient method to produce green hydrogen by electrolysis of water and steam using green electric power, aiming at commercialization in the latter half of 2020s.This report presents the current development status of key technologies, focusing on the results of cell stack test.
