“…The LSS provides a higher energy density, reducing the specific tank size and storing a higher quantity of heat energy [13]. The LSS system for water and air heater generally uses low-temperature PCM, which mainly comes from fatty acid [14], hydrocarbon wax [15], and natural wax [16]. The low thermal response for the LSS tank is overcome by using solid additives [17], a high surface area heat exchanger [18], and nano-enhanced working fluid [19].…”

The present study assesses the heat characteristic of the nitrate-salt mixture as a phase change material (PCM) for a medium-temperature latent storage system (LSS). Two binary and ternary mixtures are evaluated, which demonstrate different thermal behaviour. The highest melting and latent heat capacity is obtained by KNO3(0.4)/NaNO3(0.6) at 223.8 °C and 161.5 J/g. However, it has a higher supercooling degree with a partial phase transition between 217.6 °C and 251.5 °C, making it unfeasible for a medium-temperature LSS tank. The ternary mixture (TM) with NaNO2(0.4)/KNO2(0.53)/NaNO3(0.7) demonstrates a stable phase transition with minimum partial phase transition (22.1 °C) and suitable heat of fusion (98.1 J/g). Further evaluation through static thermal profiling demonstrates that the TM has a notable performance during solid-sensible charge with a charge level indicator (CLI) around 45.3 %–49.1 %. The TM can be charged up to 85.7 % until the end stage of the phase transition. It promotes a better storage capacity with suitable performance since the system can be charged effectively at a suitable temperature range (< 160 °C) for various applications. The micrograph observation indicates some dispersed particles and local agglomeration, which makes phase stabilization as an advantageous method to promote a stable phase change process. The TM can be considered a suitable PCM for a medium-temperature LSS tank that allows for a better solar thermal renewable system operation.

Phase change materials (PCMs) have drawn considerable attention in recent years due to their capability of storing and releasing thermal energy during phase transformation. However, traditional PCMs face challenges like limited thermal conductivity, leakage while phase transformation from solid to liquid, thermal degradation, and durability. Researchers have concentrated on creating shape‐stabilized PCMs (SSPCMs) employing polymers as the supporting matrix to overcome these difficulties and incorporating highly thermally conductive additives to improve thermal conductivity. Compared to conventional PCMs, polymer‐based SSPCMs are often more flexible, lightweight, and durable and may be easily customized according to specific applications. Various factors like PCM loading, thermal cyclability, cost‐effectiveness and environmental concerns must be considered while constructing polymer‐based SSPCMs. This review paper comprehensively explored various polymers, including polyurethane, polyacrylates, polyolefin, and so on, as promising supporting materials for SSPCMs due to their relatively high mechanical strength, compatibility with PCM, excellent thermal stability, and chemical resistance. Natural polymers like chitosan, cellulose, and starch are also considered for eco‐friendly solutions. We have also discussed about specific properties of each polymer, their cost‐effectiveness, and the environmental impact while developing such SSPCMs to guide researchers in material selection. Applications of polymer‐based SSPCMs in solar energy storage, medical devices, building materials, electronics, transportation industry, and waste heat recovery are briefly discussed. Finally, some future development areas have been discussed to attract the attention of new researchers in this field. The information provided in this review will assist readers in understanding polymer‐based SSPCM and selecting their desired polymer for support material with diverse application methods.
