Abstract
In this article, we propose a novel hydrogen storage system which has both lightness and compactness a combination of a lightweight high pressure vessel and hydrogen storage alloy. The system is expected as a promising formation to improve the properties of hydrogen storage techniques in weight and volume other than the conventional techniques using compressed hydrogen or hydrogen storage alloy individually. The novel system requires a hydrogen storage alloy with higher volumetric hydrogen density as well as higher gravimetric density, and with higher equilibrium dissociation pressure than the hydrogen storage alloys which have ever been used for hydrogen storage systems.
