Practical utilization of solar energy is highiy expected as an energy resource in the future. However, the low, intermittent and fluctuating energy density of the solar energy is an essential problem in the utilization. The energy storage and conversion are most prominent solutions. This paper reports of the research and development of solar-hydrogen hybridized vehicle (SHHV) in which solar energy and hydrogen energy are combined. We hope the active participation of private and public sections in this work.
