The current technologies for solar chemical fuel productions using concentrated solar radiation as an energy source and carbonaceous resources as a chemical source such as coal cokes and natural gas were mainly reviewed in this paper. These energy conversion technologies enable productions of long term storable clean energy carrier from solar energy and solar energy transportation from sunbelt to remote countries, such as Japan. Concentrated solar radiation has some specific properties such as high density, heterogeneous distribution of thermal flux, and frequent thermal transients due to the fluctuating insolation. Thus, some solarspecific reactors/reformers have been developed to convert the high temperature solar heat into hydrogen and synthetic gas of carbon monoxide and hydrogen via solar thermochemical processes of water-splitting, natural gas reforming and coal gasification. In this paper, research activities in Niigata University are mainly introduced in this paper.
