| Research Abstract |
It was revealed that the reversible H_2 storage and release could be performed by H_2 pressure swing without destroying hydrate-cages. H_2 absorption process contains the following two steps : H_2 adsorption and diffusion for hydrate. In both steps, the difference of H_2 fugacity between inside and outside of hydrate may play a role as the driving force. In the present study, the storage amount and absorption period of H_2 are about 1.0 mass% and 3 hours, respectively.
