Using solar energy to drive high-temperature thermochemical process has the potential to produce hydrogen or synthesis gas. Both solar energy and fossil resources (including water or biomass) are upgraded through this integrated process. Recently,research interests have been focused on this process. The solar high-temperature reactor (SHTR) is one of the keys to this process. The shortcomings of traditional SHTRs,such as large temperature gradient in reaction areas,low thermo-chemical conversion efficiency and inactivation of reactants due to sintering,are the main barriers to its commercialization. Principles of solar thermochemical conversion are briefly introduced. The solar high-temperature thermochemical conversion process was originally hydrogen production by direct thermal dissociation of water,and evolved to modification or upgrading of fossil resources. SHTRs were derived from solar collectors (also known as solar absorbers or receivers) commonly used in solar tower or dish concentrating power generation. The feasibility and limitation of this transplantation are discussed. Directly and indirectly irradiated SHTRs are classified and reviewed. The distinct advantages of high heat transfer performance and uniform temperature are summarized for novel heat pipe/plate based SHTRs. Also,typical demonstrations of indirectly irradiated SHTRs in thermochemical conversion process are presented. At last,the future main research areas and potential applications of advanced indirectly irradiated heat pipe/plate based SHTRs,are presented.
