“…High-temperature solar energy plants (temperature above 300°C), in particular have attracted the attention of researchers world-wide. Inorganic salts as PCMs can effectively store the energy at high temperatures due to their capacity to produce large amount of latent heat with minimal change in density during phase change form solid to liquid [45].…”

The research on phase change materials (PCMs) for thermal energy storage systems has been gaining momentum in a quest to identify better materials with low-cost, ease of availability, improved thermal and chemical stabilities and eco-friendly nature. The present article comprehensively reviews the novel PCMs and their synthesis and characterization techniques for improving the properties and long-term storage capabilities. They include eco-friendly PCMs based on wood and tree fruit oils, microPCMs, nanoconfinement of organic PCMs, metal organic PCMs, bio-based PCMs, metal organic framework (MOF) PCMs and form-stable PCMs with gelators. The novel approaches such as cryogenically treated microencapsulated PCMs and treating them with photo-switching dopants to improve the properties are also presented. This review provides the useful insights about recent advances in the field of PCMs. The phase change slurries can effectively improve the thermal performance of photovoltaic/thermal systems. The thermal conductivity of PCMs can be enhanced significantly by PCM slurries, MOFs, exfoliated graphite nanoplatelets and composite PCMs. Optical control of PCMs by doping them with azobenzene dopants is found to be the most promising technique to improve the thermal stability and long-term storage capacity of PCMs. Cyclic cryogenic treatment by liquid nitrogen followed by heat treatment of PCMs can improve the latent heat, thermal and chemical stabilities significantly. The insightful information presented in this article can serve as an important tool for the researchers in the field of PCMs research to further innovate the technology in different applications such as thermal management of buildings, solar energy storage and cryogenic storage etc.

“…PCMs are classified based on the phase change temperature (lower, higher, and intermediate temperature). Mao et al 4 have classified PCMs, according to melting temperature, into three categories which are low‐temperature materials, medium temperature materials, and high temperature materials, see Figure 2.…”

Phase change materials (PCMs) are used as latent heat thermal energy storage materials. The fields of application for PCMs are broad and diverse. Among these areas are thermal control of electronic components and thermal building regulations. These areas are used as heat and cold storage materials. The low thermal conductivity of PCMs is one of the significant and severe technological problems of PCMs. This paper presents a review of the latest works using PCMs in the thermal management of electronic components, buildings, and heat exchangers. Besides, it provides concise pieces of information on the classification of PCMs, their advantages, disadvantages, and thermal storage systems.

Demand for domestic hot water and heating is rarely perfectly concurrent with solar irradiation, which means that collectors can overheat in periods of high incident radiation and low demand. Phase change materials have been used as energy storage in space heating applications to absorbs excess heat during low demand periods for use in peak demand periods. This paper reviews the current state of research on the possibility of application of such materials as energy storage for solar collectors, in order to avoid collector overheating. Finally, various materials were evaluated and ranked for this application based on required properties and price. An example model of such materials being applied in a typical family house domestic hot water solar system is also provided.
