研究開始時の研究の概要 |
The main aim of this research is to develop a prototype thermochemical storage (TCS) system that store and release energy by redox reactions at temperatures between 600°C–1000°C for higher thermal efficiency and lower electricity cost.

研究実績の概要 |
In order to buy some essential components from overseas, some delays happened due to COVID pandemic. However, Using the validated model, an optimized receiver-reactor has been designed and constructed. Iron-manganese oxide with the Fe/Mn molar ratio of 2:1 has been developed as a heat storage material for high temperature thermochemical storage. X-ray diffraction (XRD) and thermogravimetric (TGA) analyses were conducted. The synthesized materials have been thermally reduced under a nitrogen atmosphere, and the reduction kinetics have been investigated.

今後の研究の推進方策 |
Sensible/thermochemical heat storage experiments of the receiver will be conducted by solar simulator using promising particles. The reaction rate and efficiency of the receiver will be comprehensively analyzed both experimentally and numerically. Then, using the optimized numerical model and the experimental demonstration results, an upscaled receiver will be designed for solar demonstration by our beam-down solar concentrator. The effect of operating parameters on the thermo-fluid flow and efficiency of the receiver will be studied numerically for various DNIs (summer and winter).
