The association of concentrated solar energy and biomass gasification has often been suggested as an interesting alternative to conventional autothermal processes where a significant portion of the biomass has to be used for heat generation to drive endothermic reactions. It is a clean process able to produce high quality synthesis gas with a higher output per unit of feedstock and that allows for the chemical storage of solar energy in the form of a readily transportable fuel, among other advantages. The present paper describes the latest advances in solar thermochemical reactors for gasification of carbonaceous feedstocks.
