4. Applications in energy carrier production
Solar furnaces are technological research and development tools in the fields of electricity and hydrogen production. They are used to qualify components such as solar receivers or reactors, and to validate reaction schemes for hydrogen production using thermochemical cycles.
For these two applications, a simplified exergy analysis (ideal concentrator, black body) shows that there is an optimum operating temperature range corresponding to a given concentration factor. Indeed, if we consider that radiation is the sole source of energy losses in the solar absorber (receiver or reactor), losses increase in T 4 and absorption efficiency varies in the opposite direction. Conversely, the transformation efficiency of energy, absorbed by a thermodynamic machine or by a chemical reaction,...
