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. Redox active metal oxide-based 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. This presentation highlights the challenges and progress from multidisciplinary and international efforts that has been progressing down a technical path for systems, novel reactors, and materials design and discovery for making hydrogen, liquid hydrocarbon fuels, and storing thermal energy from concentrated sunlight based on a two-step metal oxide redox cycle motivated to address the dual challenges posed by the strategic and economic importance of petroleum and the increasing concentration of atmospheric carbon dioxide.
