“…The latent TES (LTES) system is considered as an efficient way of storing thermal energy. A latent heat TES (LHTES) system stores the energy when the material changes a phase from one form to another form such as a solid form to solid form, solid form to liquid form, and liquid form to gas form with constant temperature . Solid‐to‐liquid phase transition is the most widely used technology in thermal applications.…”

Summary Because of the unstable and intermittent nature of solar energy availability, a thermal energy storage system is required to integrate with the collectors to store thermal energy and retrieve it whenever it is required. Thermal energy storage not only eliminates the discrepancy between energy supply and demand but also increases the performance and reliability of energy systems and plays a crucial role in energy conservation. Under this paper, different thermal energy storage methods, heat transfer enhancement techniques, storage materials, heat transfer fluids, and geometrical configurations are discussed. A comparative assessment of various thermal energy storage methods is also presented. Sensible heat storage involves storing thermal energy within the storage medium by increasing temperature without undergoing any phase transformation, whereas latent heat storage involves storing thermal energy within the material during the transition phase. Combined thermal energy storage is the novel approach to store thermal energy by combining both sensible and latent storage. Based on the literature review, it was found that most of the researchers carried out their work on sensible and latent storage systems with the different storage media and heat transfer fluids. Limited work on a combined sensible‐latent heat thermal energy storage system with different storage materials and heat transfer fluids was carried out so far. Further, combined sensible and latent heat storage systems are reported to have a promising approach, as it reduces the cost and increases the energy storage with a stabilized outflow of temperature from the system. The studies discussed and presented in this paper may be helpful to carry out further research in this area.

“…Thermophysical, kinetic and chemical properties of such salt hydrates, which can possibly meet the requirements, are presented in Table 1. The most representative salt hydrates are sodium sulfate decahydrate, calcium chloride hexahydrate, sodium phosphate, dodecahydrate and magnesium chloride hexahydrate [5,11]. However, the phase transition temperature range of single salt hydrate cannot always meet the requirements of practical application.…”

Using phase change materials (PCMs) for thermal energy storage has always been a hot topic within the research community due to their excellent performance on energy conservation such as energy efficiency in buildings, solar domestic hot water systems, textile industry, biomedical and food agroindustry. Several literatures have reported phase change materials concerning various aspects. Among these materials, salt hydrates are worthy of exploring due to their high-energy storage density, rational price, multiple sources and relatively good thermal conductivity. This paper reviews the present state of salt hydrates PCMs targeting classification, properties, defects, possible solutions as well as their idiographic features which are suitable for applications. In addition, new trends of future research are also indicated.

“…Season-dependent sources of excess heat are solar thermal energy systems for domestic heating. Phase-change materials (PCMs) [1][2][3] can absorb and release excess heat through reversible changes in their solid state structures. For such processes, the term latent heat thermal energy storage was coined.…”

New Polymorphs of the Phase-Change Material Sodium Acetate

et al. 2018

Abstract:Two new polymorphs of the phase-change material sodium acetate were characterized by single-crystal X-ray diffraction. A tetragonal form was found first. It converted to a orthorhombic form after measurement of a single crystal of the tetragonal form at 100 K and subsequent warming to ambient temperature. Hirshfeld surface fingerprint plots show the different packing environments of the two new compared to the two known orthorhombic polymorphs Forms I and II. The accuracy and precision of the structures were improved compared to conventional independent atom model refinement through the use of aspherical scattering factors of the invariom database. We think that the layered nature of all sodium acetate forms, and the thereby limited ("quantized") availability of vibrational modes, is related to the phenomenon of supersaturation, which is connected to its phase-change properties.
