Redox cycles with doped calcium manganites for thermochemical energy storage to 1000 °C
Abstract
Redox cycles of doped calcium manganite perovskites (CaMnO3–δ) are studied for cost-effective thermochemical energy storage at temperatures up to 1000 °C for concentrating solar power and other applications. Furthermore, if the thermodynamics and kinetics for heat-driven reduction can be tailored for high temperatures and industrially accessible low O2 partial pressures (PO2 ≥ 10–4 bar), perovskite redox cycles can offer high specific energy storage at temperatures much higher than state-of-the-art molten-salt subsystems.
