R & D on hydrogen storage materials have been carried out since 1974 when so-called “oil crisis” occurred. Recently, after the Japanese government announced “Carbon neural achieving in 2050”, hydrogen energy has attracted much more attention than before. The New Strategic Energy Plan that decided by the cabinet in October 2021 mentions hydrogen is utilized in all the energy sectors. Hydrogen storage materials are applied to large scale hydrogen transport, storage of fluctuated renewable energy in the form of hydrogen, storage of hydrogen nearby building and residential houses and so on. Large scale and long-term national projects for commercialization of large-scale hydrogen transport are starting. However, promotion of fundamental scientific research and basic technology development are also strongly desired.
