A newly device was developed for gasification of woody biomass using concentrated solar radiation. A renewable energy is expected against global warming and global energy problems in near future. Gasification method is focused because low molecular gases like H2, CO, CH4, ... are easily produced under high temperature for any biomass. Especially, hydrogen is useful for a gas fuel in any purpose. It is cleared that hydrogen from woody biomass is prodused in the range of temperature 700-1000℃ mainly. On the other hand, this temperature region is readily achived by concentrated solar radiation. So, a newly gasification device for biomass using concentrated solar radiation is developed. In the first step, a new type of fluidized bed gasification device was designed and developed for reduction of tar problem, and flowing gas. Some samples were gasified by this device and generated gases were analyzed by gas chromatography analysis. Additionally, a concentrated solar radiation device is preparing for heating of gasification.
