IN SITU XAS OF CERIA MATERIALS FOR THE THERMOCHEMICAL CONVERSION AND STORAGE OF CONCENTRATED SOLAR THERMAL ENERGY

摘要

Thermochemical redox cycles present a viable pathway to the efficient conversion and storage of solar energy in chemical bonds by producing syngas1,2. Using well established routes, syngas can further be processed to solar hydrocarbon fuels. The production of H2 from H2O and/or CO from CO2 can be carried out in a two-step redox cycle driven by high temperature heat provided by concentrated solar radiation.
