Redox-active oxide materials for thermal energy storage
| DWPI Title: Thermochemical system used for storing heat energy, comprises concentrated solar receiver, and thermochemical composition comprising perovskite material provided to concentrated solar receiver |
| Abstract: Thermochemical storage materials having the general formula AxA′1-xByB′1-yO3-δ, where A=La, Sr, K, Ca, Ba, Y and B=Mn, Fe, Co, Ti, Ni, Cu, Zr, Al, Y, Cr, V, Nb, Mo, are disclosed. These materials have improved thermal storage energy density and reaction kinetics compared to previous materials. Concentrating solar power thermochemical systems and methods capable of storing heat energy by using these thermochemical storage materials are also disclosed. |
| Use: Thermochemical system used for storing heat energy (claimed). |
| Advantage: The thermochemical system has increased storage density. The perovskite material has improved thermal storage energy density and reaction kinetics. |
| Novelty: A thermochemical system comprises a concentrated solar receiver, and a thermochemical composition provided to the concentrated solar receiver. The thermochemical composition comprises a perovskite material (I). |
