Reversing combustion and recycling carbon dioxide and water back to liquid hydrocarbons is an attractive option for storing solar energy and mitigating the growth of atmospheric CO2 concentrations. For any such process, high solar-to-fuel efficiency and material availability is critical for large scale viability and favorable economics. Thermochemical approaches for solar-to-fuel have the potential to be highly efficient as they avoid inherent limitations of photosynthesis and 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 H2O are the foundation of the Sunshine to Petrol project.
