Final Report Summary - SUNFUELS (SOLAR THERMOCHEMICAL PRODUCTION OF FUELS)

Sustainable utilization of liquid hydrocarbon fuels for transportation, especially for the aviation sector, can be realized with the help of technologies that convert H2O and CO2 into fuels using solar energy. Solar thermochemical approaches for splitting H2O and CO2 using concentrated solar radiation inherently operate at high temperatures and utilize the entire solar spectrum, and as such provide a favorable thermodynamic path to solar fuels production at high rates and with high efficiency. This project developed the science and technology for producing solar syngas from H2O and CO2 via two-step thermochemical redox cycles. The research work comprised the design, testing, modeling, and optimization of fully integrated solar fuel production technologies. Specifically, novel materials and structures were developed and incorporated in optimized solar reactors for achieving volumetric absorption of concentrated solar radiation, enhanced heat and mass transport, fast redox kinetics, high reaction selectivity, high specific fuel yield, long-term stability, scalability, and robustness.
The theoretical and experimental findings provide compelling evidence of the viability of the solar thermochemical redox technology for converting H2O and CO2 to fuels. They further elucidated the efforts required for the large-scale industrial implementation of the solar fuel technology, which can make use of the solar concentrating infrastructure already established for commercial solar thermal power plants.
