Abstract
First of all, hydrogen energy related government budgets in Japan, USA and EU were summarized. Among a number of required technology to introduce hydrogen society, the hydrogen storage technique was focused in this article. The technique is classified in three ways, such as pressurized hydrogen, liquid hydrogen and hydrogen storage medium tank. In each technique, the high pressure science and technology is important to materialize applications of hydrogen storage systems. In addition, the recent research of new hydrides prepared by autoclave synthesis and high-pressure work in solid-state was also mentioned.
