Solar thermochemical splitting cycles (TSCs) are a promising technology for producing renewable hydrogen, or hydrocarbon fuels, from a feedstock of H 2 O, or H 2 O and CO 2 , and solar energy. At present, perovskites materials have been only investigated in isolation for potential use in high‐temperature two‐step TSC. Their ability in isolation to gain or lose oxygen at different temperatures and their heating duties for CO 2 or H 2 O are not satisfactory arguments in favor of or against the specific use. The design, prototyping, and testing of a specific solar receiver/reactor for the production of CO or H 2 are necessary to prove the technology.
