Abstract

Solar thermochemical reactors to split carbon dioxide or water via the non-stoichiometric reduction and oxidation of cerium dioxide (ceria) offer the potential for efficient production of synthetic fuel and storage of sunlight in chemical form. A 3kWth reactor prototype with a cylindrical receiver cavity lined with six tubular reactive elements integrated with a high-temperature gas phase heat recovery system has been developed to implement an isothermal ceria redox cycle at 1773 K. A transient computational model of the reactor couples radiative transfer, fluid flow, heat and mass transfer, and the reaction kinetics to predict fuel production rates. The model predicts continuous fuel production at 3.4 × 10−4 mol s−1 for carbon dioxide splitting.
