Hydrogen storage alloys can store large amounts of hydrogen safely. The rapid spread of renewable energy sources has led to the development of hydrogen energy systems. The tanks using these hydrogen storage alloys have been developed since the 1970s, and are suitable for use in these hydrogen energy systems. In this paper, the status of the development of hydrogen storage alloy tanks and the future prospects are presented by focusing on the projects of their installation in Japan.
