Development research on Metal Hydrides was actively conducted in Japan from the 1970s as a dream new material that hydrogen storage density is comparable to liquid hydrogen. However, people other than limited researchers also got metal hydrides in the 1980s, and now they can actually use them. In the early 1980’s, it became a big opportunity that aluminum Canister filled with Metal Hydride called AHT 5 of Billings became available in Japan as well. I think the Metal Hydride Canister is the simplest and clearest one as a usage form of the Metal Hydride. However, when trying to put Metal Hydride Canister into practical use in Japan, it is necessary to overcome various obstacles such as laws and regulations. I would like to explain the situation around here in this paper.
