Abstract: Before almost all demand for liquid hydrogen had been limited in space development use. But recently, market share of liquid hydrogen in sales volume has become up to 14% in Japan, because a large-scale liquid hydrogen production plant has been operated since 2006 and then, instead of hydrogen gas delivery, liquid hydrogen delivery has been increasing steadily in industrial use such as electronic and metal industries. One of the reasons for increase in the liquid hydrogen delivery is its high storage density and high delivery efficiency compared with the hydrogen gas delivery. Because of these characteristics, liquid hydrogen is also expected to be one of a promising energy carrier in the future. In addition, because of its features such as high purity and cryogenic temperature, liquid hydrogen is expected to be available for hydrogen stations for fuel cell vehicles and superconducting magnetic energy storage systems (SMES).
