Abstract
In order to improve the dispatchability of next-generation concentrated solar power (CSP) plants, Ca(Fe0.1M0.9)O3 has been proposed as high temperature (>800 °C) thermochemical energy storage (TES) materials. Only recently, the thermodynamics of Ca(Fe0.1M0.9)O3 oxide has been measured through Van't Hoff approach via thermogravimetric (TG) analysis, thus allowing access to the oxygen non-stoichiometry profiles (δ(T, pO2)) under different temperature and oxygen partial pressure pO2. The material TES performance is here investigated through laboratory scale reactor tests carried out under conditions considered representative of future CSP plants. Remarkably, the material exhibits the same δ(T, pO2) profile as the one computed from the thermodynamics at a significantly larger scale (~40g). According to the obtained results, Ca(Fe0.1M0.9)O3 oxide appears ideally suited for thermal energy storage applications with a large total (thermochemical and sensible) heat storage capacity (~916 kJ/kgABO3) and good scalability.
