The Sunshine to Petrol effort at Sandia aims to convert carbon dioxide and water to precursors for liquid hydrocarbon fuels using concentrated solar power. Significant advances have been made in the field of solar thermochemical CO2-splitting technologies utilizing yttria-stabilized zirconia (YSZ)-supported ferrite composites. Conceptually, such materials work via the basic redox reactions: Fe3O4→ 3FeO + 0.5O2 (Thermal reduction, >1350°C) and 3FeO + CO2→ Fe3O4 + CO (CO2-splitting oxidation,
