Abstract

Converting carbon dioxide and water to hydrocarbons is an attractive option for storing solar energy and, coupled with appropriate CO2 capture technology, for recycling carbon and impacting atmospheric CO2 concentrations. For any process, high solar-to-fuel efficiency is necessary for large scale viability and favorable economics. Thermochemical approaches for solar-to-fuel conversion are potentially highly efficient as they avoid the inherent limitations of photosynthesis and also sidestep the solar-to-electric conversion necessary to drive electrolytic reactions. Solar-driven two-step metal-oxide-based thermochemical cycles for producing the components of syngas, CO and H2 from CO2 and H2 0 are the basis of the "Sunshine to Petrol" project. Multi-cycle production of both H2 and CO has been demonstrated over several iron- and cerium-based compositions fabricated into monolithic pieces both in the laboratory and at the National Solar Thermal Test Facility. These compositions are being developed for deployment in a unique and continuous solar-driven reactor prototype, the counter-rotating-ring receiver reactor recuperator or CR5.
