PCM (phase change material) is one of the most popular media in TES (thermal energy storage) system for its high energy storage density and suitable melting temperature. However, its low heat transfer performance leads to low rate of heat stored and released. In this paper, a highly thermal...

The possibility of using magnesium based eutectic metal alloys as phase change material (PCM) for thermal energy storage (TES) in concentrated solar power (CSP) applications is analysed. An extensive thermophysical characterization of the Mg–51%Zn eutectic metal alloy between room temperature...

Phase change materials (PCM) with a transition temperature around 45°C can be used in various applications, e.g. as intermediate storages for heat pumps in space heating systems, for the thermal protection of battery systems or to increase the efficiency of dishwashers by preheating water. At...

High-temperature PCM is a key component for storing latent heat. This is necessary for efficient energy storage in connection with the two-phase heat transfer fluid water/steam. Due to the low thermal conductivity of the nitrate salts used for high-temperature PCM storage, it is necessary to...

The primary objective of this study is to develop encapsulated phase change materials (EPCMs) capable of storing thermal energy at temperatures above 750 °C. EPCM with magnesium chloride as phase change material (PCM) are considered here for application in concentrated solar power (CSP)...

A very common problem in solar power generation plants and various other industrial processes is the existing gap between the period of thermal energy availability and its period of usage. This situation creates the need for an effective method by which excess heat can be stored for later use....

An important option for increasing the efficiency in Concentrated Solarthermal Power (CSP) is the development of systems generating steam directly in the solar field. To produce dispatchable and affordable electrical power, the integration of an efficient and economical thermal energy storage is...
