Hydrogen has been considered as an alternative for the future energy source. However, though a lot of efforts to explore high efficiency storage materials at feasible conditions were done, it seems to be at a stand-still unless there appears a novel breakthrough. Most of the tries on the hydrogen storage works were based on the design-synthesis-measurement(specific surface area and c(P,T)). Less tries on the measurements of the structure and/or the dynamics of the hydrogen and sorbing materials during the sorption and desorption processes have been reported. Understanding of the sorption/desorption mechanism is an essential factor prior to the design of a new material. To investigate the mechanism for the hydrogen storage we have recently established an in-situ neutron diffraction sample environment which enable us to obtain the neutron diffraction patterns and the adsorption capacity of the state (P and T). And we are now trying to construct a new and powerful experimental platform, ' In-situ Combined Scattering (neutron diffraction + Raman + c(P,T)) Apparatus', which may give us more insightful information on the hydrogen storage and it is expected to be operational in this year. Some results from the in-situ neutron diffraction experiment will be introcuded and discussed.
