“…The utilization of renewable energy, especially solar energy, is considered to be a feasible way to solve the global warming, ecological degradation, and energy crisis. − Concentrated solar power (CSP) coupled with heat storage systems is regarded as one of the most promising technologies for the large-scale and sustainable utilization of solar energy. , Thermochemical heat storage (TCHS) technologies have been considered as the heat storage system for the next-generation CSP plants because of their wide operating temperature range, high heat storage capacities, and low heat loss. , CaCO 3 /CaO TCHS achieves the effective storage and release of solar energy through the calcium looping (CaL) (i.e., the reversible reactions of CaCO 3 calcination and CaO carbonation), as displayed in eq . With the advantages of convenient coupling with supercritical CO 2 power cycles, low feedstock prices, high heat storage density (about 3178 MJ/t theoretically), and high operating temperatures (over 800 °C), CaCO 3 /CaO TCHS is believed to be one of the most prospective TCHS technologies. , CaCO 3 ( s ) ↔ CaO ( s ) + CO 2 ( g ) 0.25em ΔH 29 8k = 178 0.25em kJ / mol …”

CaCO3/CaO thermochemical heat storage is one of the most prospective schemes for large-scale heat storage in the next-generation concentrated solar power plants. MgO and ZnO can cooperatively enhance the heat storage performance of CaO. However, the underlying mechanism for the cooperative promotion of MgO and ZnO on the heat storage performance of CaO remains unidentified. In this work, density functional theory (DFT) calculations were applied to analyze the role of MgO and ZnO in CaCO3/CaO heat storage processes. The thermodynamic properties, structural evolution, and exothermic reactivity of CaO-based materials were studied by DFT. Because of the influence of ZnO on Ca–O bonds, ZnCa3O4 has a lower binding energy than Ca4O4. ZnO enlarges the lattice heat capacity and the phonons average velocity of CaO, thus improving the thermal conductivity. The sintering resistance of M-C is mainly due to the strong interaction of Mgs–Oc, but the interaction of Cac–Os is weak. With the doping of ZnO, the strength of Cac–Os is improved, resulting in a stronger sintering resistance of M-ZC. The exothermic reactivity of CaO is simultaneously affected by the interactions between C and O in CaO and between Ca and O in CO2. MgO–ZnO codoping facilitates the interactions between Ca and O but harms the interactions between C and O. With their combined influence, the Hirshfeld charge transfer of M-ZC for CO2 is −0.5 e, which is 1.39 times that of CaO. Besides, MgO–ZnO-codoped CaO was prepared by the wet-mixing method and had heat storage tests. The experimental results support the result obtained by the DFT calculation. Therefore, the probable mechanism of the cooperative promotion on the CaCO3/CaO heat storage process of CaO resulting from MgO–ZnO codoping was determined.

Ionic liquids and their various analogues are without doubt the scientific sensation of the last few decades, paving the yellow brick road to a worldly version of Oz's green “Emerald city” – a more sustainable society. Their versatile suite of properties, originating from an almost inconceivably large number of possible cation and anion combinations, allows tuning of the structure to serve a desired purpose. Ionic liquids hence offer a myriad of useful applications from solvents to catalysts, through to lubricants, gas absorbers and azeotrope breakers. The purpose of this review is to explore the more unexpected of these applications, particularly in the energy space. It guides the reader through the application of ionic liquids and their analogues as i) phase change materials (PCMs) for thermal energy storage, ii) organic ionic plastic crystals (OIPCs), which have been studied as battery electrolytes and in gas separation, iii) key components in the nitrogen reduction reaction (NRR) for sustainable ammonia generation, iv) as electrolytes in aluminum ion batteries, and v) in other emerging technologies. We conclude that there is tremendous scope for further optimizing and tuning of the ionic liquid in its task, subject to sustainability imperatives in line with current global priorities, assisted by artificial intelligence.This article is protected by copyright.
