The interest and possibilities of conducting steam gasification of biomass (SGB) assisted by concentrated solar energy (CSE) at high temperature as external heat source for applications at large scale is studied. First the different options to conduct SGB to produce syngas and hydrogen are analyzed. Thereafter the possibilities of integrating CSE in SGB are investigated, including the ways to transfer the heat to the reactor, as well as methods to increase fuel conversion efficiency and the solar share in the gas produced. Finally, some original ideas to conduct SGB with solid particles as energy carriers heated by CSE are proposed.
