“…Let us now demonstrate how the results and approaches described above can be employed to evaluate the performance of complex oxides in some real-life thermochemical applications related to solar energy conversion and storage. Thermal energy input, in this specific case produced by concentrated solar power, is stored in oxides in accordance with the following equation: where Δ H sens ◦ = ∫ T 0 T 1 C p d T , so-called “sensible” energy, ,,, denotes the specific heat storage capacity, which is a purely thermal contribution to Δ H total ◦ , excluding any heat effects resulting from the changes in the oxide composition. In turn, Δ H red ◦ in eq is the “chemical”, oxygen exchange-related energy storage capacity .…”

“…The overall efficiency of a temperature and pressure swing adsorption device based on eq will depend to a great extent on the efficiency of the other parts of the system such as pumps and heat exchangers . As for the material performance, while neither SrFeO 3−δ nor RBaCo 2 O 6−δ (R = Pr, Eu, Sm, or Gd) demonstrates a record equilibrium OSC, especially at lower temperatures (below ∼773 K), their OSC is nevertheless comparable with that of many other oxides, including those with perovskite-like ,, and non-perovskite structure . Among the latter, a much higher equilibrium OSC and a much higher energy storage capacity characterize primarily stoichiometric oxides that undergo phase changes with abrupt O 2 loss or gain, such as Co 3 O 4 or CoO, respectively.…”

“…Then, the ab initio calculations precisely examine this subset of the candidates. These virtual screenings have been increasingly employed for materials discoveries in catalysis 10,11 , organic light-emitting diodes 7 , thermoelectric compounds 12 , photovoltaic materials 13 , and Li-ion cathodes 3,14,15 .…”
