Terrific piece of cutting edge chemistry from “oil country”, which looks beyond proof of concept to using solar-generated heat and full spectrum light to drive a single-step, clean, commercial process producing fuel-value hydrocarbons + oxygen from carbon dioxide + water. Key to the future commercial model of what they’re calling “reverse combustion” appears to be improved catalysis and increased temperature/pressure to shift product distribution towards higher-carbon hydrocarbons. The group at University of Texas, Arlington deserved to get this out-of-the box development in PNAS.
