Previous models based on thermodynamic considerations have identified the properties desired for reactive oxides that can be used as oxygen storage materials in thermochemical cycles to produce fuel from sunlight. However, there are several important assumptions made in such models, such as the neglect of the energy required to preheat unreacted species and the assumption of constant vacuum pump efficiency...
A new reactor concept for two-step partial redox cycles is presented and evaluated by transient simulation that considers heat and mass transfer along with reaction kinetics. The major difference between the reactor described herein and previous designs is that the conversion from solar to chemical energy is divided into two steps: sunlight-to-thermal energy conversion accomplished with a liquid metal...
