Thermochemical energy storage (TCS) systems are receiving increasing research interest as a potential alternative to molten salts in concentrating solar power (CSP) plants. In this framework, alkaline-earth metal carbonates very promising candidates since they can rely on wide availability, low cost, high volumetric density (>1 GJ m–3), relatively operating temperatures (>800 °C), nontoxic and noncorrosive chemical nature, no occurrence of any side reactions involving the production undesired byproducts. Therefore, their reversible calcination/carbonation reaction with CO2 be used store/release CSP However, spite these features, TCS field is new, most it still limited lab-scale. great efforts needed bridge gap from fundamental real-scale application implementation TCS-CSP systems. This manuscript reviews state-of-the-art carbonate-based for particular, literature has been analyzed in-depth, paying attention (i) materials development, focus solutions available improve durability (namely, ability withstand repeated carbonation/calcination cycles); (ii) design reactor configuration both solar-driven endothermic calcination exothermic carbonation reaction, focusing optimization concept, based physicochemical properties working reagents.

The Global South comprising economically disadvantaged regions of the world face various challenges such as limited access to electricity, clean water, industrialization, and food security. Solar energy, a sustainable abundant resource, holds great potential address these challenges. Despite its immense potential, encounters hurdles related technology adoption, infrastructure, financial constraints. This review examines history, classifications, global statistics, merits, demerits solar in South. Furthermore, it delves into applications including extreme environments, residential electricity generation, transportation, industrial usage this region. paper concludes by providing new insighths highlighting significant role energy can play shaping future if are adequately addressed, opportunities embraced.

Solar thermochemical hydrogen (STCH) generation is a promising approach for eco-friendly H2 production, but conventional STCH redox compounds cannot easily achieve desirable thermodynamic and kinetic properties phase stability simultaneously due to rather limited compositional space. Expanding from the nascent high-entropy ceramics field, this study explores new class of compositionally complex perovskite oxides (La0.8Sr0.2)(Mn(1–x)/3Fe(1–x)/3CoxAl(1–x)/3)O3 with non-equimolar designs STCH. In situ X-ray photoelectron spectroscopy shows preferential Co. The extent reduction increases, intrinsic kinetics decreases, increasing Co content. Consequently, (La0.8Sr0.2)(Mn0.2Fe0.2Co0.4Al0.2)O3 achieves an optimal balance. combination moderate enthalpy reduction, high entropy preferable surface oxygen exchange enables maximum production 89.97 mmol moloxide–1 in short 1 h duration. Entropy stabilization may contribute during cycling without transformation, which >50 cycles under harsh interrupted conditions. underlying mechanism further elucidated by density functional theory-based parallel Monte Carlo computation approach. This suggests looping.
