Outline of Final Research Achievements

It is highly required to replace fossil fuels by sustainable, renewable, and clean energy resources such as hydrogen (H2). In spite of the availability and usefulness of H2, storage and transportation of H2 are seriously difficult, because H2 gas is explosive and its volumetric energy density is quite low. In high-pressure H2 tank systems, energy-consuming cryogenically-cooling equipment is required to store pressurized hydrogen in a liquid form. Hence, low-cost and energy-efficient storage of hydrogen is definitely needed for stationary and portable applications in the hydrogen-delivery infrastructure in a small-scale micro-grid for the electric power supply in the near future. In this context, catalytic dehydrogenation and hydrogenation reactions of organic and inorganic molecules, especially naturally-derived　compounds, in a reversible way have been studied and made possible from the viewpoint of a hydrogen donor as sustainable and renewable energy resources.
