Phase changematerials (PCMs) can absorb/release heat during the phase change. They are frequently used in thermal storage systems due to their large latent heat und isothermal nature. This paper provides an overview of the various inorganic and organic PCMs. Techniques for improving their thermophysical properties and the corrosion of metallic construction materials by inorganic PCMs are discussed. Finally, typical applications for latent-heat storage systems are presented

“…Therefore, development of an LHS system using a molten salt PCM with T m up to 1000°C is expected. In fact, studies that focus on the molten salt PCM candidates with T m > 500°C such as chloride [39,40], sulfate [1], and carbonate [41,42] have been recently reconsidered.…”

Summary Latent heat storage (LHS) using phase change materials is quite attractive for utilization of the exergy of solar energy and industrial exhaust heat because of its high‐heat storage capacity, heat storage and supply at constant temperature, and repeatable utilization without degradation. In this article, general LHS technology is outlined, and then recent advances in the uses of LHS for high‐temperature applications (over 100 °C) are discussed, with respect to each type of phase change material (e.g., sugar alcohol, molten salt, and alloy). The prospects of future LHS systems are discussed from a principle of exergy recuperation. In addition, the technologies to minimize exergy loss in the future LHS system are discussed on the basis of the thermodynamic analysis by ‘thermodynamic compass’.
