Solar thermochemistry is a novel and very promising route for the production of valuable fuels and chemicals, in which solar energy is collected and concentrated in order to supply the high temperature process heat necessary to drive highly endothermic chemical reactions. These processes produce not only a highly useful and transportable end product, but also results in the storage of a significant fraction of solar energy in the chemical bonds of the fuel molecules. This report is restricted to reviewing the current status of projects and R&D in the areas of using concentrated solar thermal energy to produce hydrogen in Spain. Some high temperature endothermic reactions for converting solar energy to chemical fuels are been investigated by CIEMAT-PSA through a range of indirect water-splitting techniques, as well as hybrid systems involving solar-driven fossil fuels transformation to hydrogen. Most of these projects are running at the solar facilities of the Plataforma Solar de Almeria. This paper summarizes the major accomplishments and challenges fulfilled in the last few years in solar thermochemical hydrogen production. Nowadays, testing evaluation of different prototypes within the most important international initiatives on thermochemical hydrogen production is underway in CIEMAT: HYDROSOL-II (100kW) and SYNPET (500kW) projects.
