In this study, we offer a perspective on the current state of material research in a part of the solar fuels community that exploits process heat derived from concentrated solar energy to power simple thermochemical gas-splitting cycles. The working fluid in this process is a nonstoichiometric oxide subject to extreme conditions that repeatedly distorts the lattice by forcing oxygen atoms to move in and out of the crystal. This technology is currently challenged by a need to discover optimal materials and derive robust processes to increase cycle efficiency. In the realm of emerging technologies for converting solar insulation to portable and storable energy carriers, this approach has already proven to be scalable with demonstrations that approach 100 kW. Innovations in materials and methods are required to increase solar utilization and process efficiency in order to achieve commercial viability.
