“…Several different sorbent composites were proposed in the literature, varying both porous matrix and salt hydrate [19]. Among them, the most common matrices are silica gel [20], clays [21] and carbonaceous structures [21], while among the salt hydrates LiCl [22], MgSO 4 [23] [22] and SrBr 2 [21] [20], and CaCl 2 [24][25][26] were deeply investigated. The experimental results reported in the literature confirmed that these materials can achieve promising TES capacities, for instance, the composite LiCl/Vermiculite developed by Grekova et al [22] can reach up to 2.3 kJ/g under seasonal storage operating conditions.…”

“…The results indicated that a 30wt% CaCl 2 solution was the most stable and had the highest energy storage capacity: 822MJ/m 3 at a charging temperature of 90 °C. In another work, Jabbari-Hichri et al (171) studied by means of TG/DCS analysis three supporting materials, silica-gel, alumina and bentonite, mixed with a 15%wt of CaCl 2 . Results showed that the CaCl 2 -silica gel composite material had the highest energy storage density, with a value of 746 kJ/kg.…”

Over the last 40 years different thermal energy storage materials have been investigated with the aim of enhancing energy efficiency in buildings, improving systems performance, and increasing the share of renewable energies. However, the main requirements for their efficient implementation are not fully met by most of them. This paper develops a comparative review of thermophysical properties of materials reported in the literature. The results show that the highest volumetric storage capacities for the best available sensible, latent and thermochemical storage materials are 250 MJ/m3, 514 MJ/m3 and 2000 MJ/m3, respectively, corresponding to water, barium hydroxide octahydrate, and magnesium chloride hexahydrate. A group of salt hydrates and inorganic eutectics have been identified as the most promising for the development of competitive thermal storage materials for cooling, heating and comfort applications in the short-term. In the long-term, thermochemical storage materials seem promising. However, additional research efforts are required.

“…En el caso de almacenamiento termoquímico, es teóricamente ilimitada debido a pérdidas térmicas mínimas. La complejidad de la tecnología de acumulación térmica mediante un proceso termoquímico es considerable, frente a los procesos de almacenamiento por calor sensibles y latentes [70]. El primer paso para desarrollar un sistema AET termoquímico es la selección de la reacción y el estudio de sus características químicas y físicas, tales como la reversibilidad, la velocidad de reacción, las condiciones de funcionamiento (presión y temperatura) y las propiedades cinéticas [1].…”

Context: The energy and environmental panorama that our societies confront nowadays, demand for renew-able, clean and abundant sources of energy, not reliant on fossil fuels and detached from the geopolitical pressures the latter represent. In this scenario solar thermal energy arises as a viable and functional option. The main disadvantage of this emerging source of energy lies in the intermittent availability of solar radiation. Because of this difficulty, efficient processes for the storage of thermal solar energy becomes a highly relevant area of research. The aim of this paper is to present a survey on this topic.Method: A bibliographic review was carried out using the Scopus catalog. The search criteria for this purpose was defined using the following terms: solar+thermal+energy+storage+materials. This search pattern was applied to the title, abstracts and keywords of the contributions. Using the bibliometric tools of the citation database, the most cited documents were selected and the survey was developed.Results: A growing interest in the scientific community regarding this energy practice is evident starting from 2010. Characteristics, advances and trends in systems that use thermal energy storage materials are presented for sensible and latent heat, materials compound changeover phase, and finally thermo-chemical thermal storage materials.Conclusions: Improving the thermal conductivity of thermal storage materials is an important trend in current re-search. On the other hand, profitable practices for micro-encapsulated phase change materials and composite materials are analyzed. The optimization of thermo-physical properties as the melting point of thermal storage materials is explored with techniques such as eutectic mixtures and hydro-carbon chain length. Although the thermochemical materials are still in laboratory stage, they have a great potential as thermal storage materials in the future, given their large energy storage capacity per unit volume.
