On board hydrogen storage is still under discussion because a suitable method has not been found. Major methods for on board application are introduced. Especially, hydrogen absorbing alloys attract attention because of large volume capacity. A technical development, a hybrid tank of compressed gas and hydrogen absorbing alloys, seems to be an ideal target in a short-medium term. Novel materials should be developed as a long term target.
