“…Liu et al [12] reviewed the storage materials and thermal performance enhancement techniques for high temperature thermal storage systems. Suitable phase change materials for high temperature processes have been investigated since the LTES system with PCM has been identified as a promising low-cost system for CSP plants; molten salt has been found as promising material to be used as the PCM for high temperature storage systems, range from 100°C to above 600°C.…”

Abstract. Solar energy has been considered as one of the promising solutions to replace the fossil fuels. To generate electricity beyond normal daylight hours, thermal energy storage systems (TES) play a vital role in concentrated solar power (CSP) plants. Thus, a significant focus has been given on the improvement of TES systems from the past few decades. In this study, a numerical model is developed to obtain the detailed heat transfer characteristics of lab-scale latent thermal energy storage system, which consists of molten salt encapsulated spherical capsules and air. The melting process and the corresponding temperature and velocity distributions in every capsule of the system are predicted. The enthalpy-porosity approach is used to model the phase change region. The model is validated with the reported experimental results. Influence of initial condition on the thermal performance of the TES system is predicted.

“…Current mature concentrating solar power (CSP) technologies have operating temperatures of 290-390C and 290-565C for parabolic trough and solar tower power plants, respectively [1]. In order to achieve higher conversion efficiency from the power block and to increase the exergy efficiency of a CSP system, a higher operating temperature is required.…”

“…Commercial deployment of CSP systems have been achieved in recent years with the two-tank sensible storage system using molten salt as the storage medium. Compared to sensible heat storage, latent heat storage using phase change materials (PCMs) can provide a smaller storage system, potentially reducing the capital and construction costs of thermal storage for CSP plants [1,3,4].…”

“…PCM is capable of storing or releasing large amounts of latent heat of fusion [2]. When solar radiation is available, the heat energy obtained from the solar receiver can be stored in the PCM by changing the phase of the PCM from solid to liquid, which is called the charging process [1]. Later on, during cloudy periods or over the night, the stored heat can be recovered and used for increasing thermal comfort.…”

Phase change materials (PCMs) selection and prioritization for comfort application in buildings have a significant contribution to the improvement of latent heat storage systems. PCMs have a relatively large thermal energy storage capacity in a temperature range close to their switch point. PCMs absorb energy during the heating process as phase change takes place and release energy to the environment in the phase change range during a reverse cooling process. Thermal energy storage systems using PCMs as storage medium offer advantages such as: high heat storage capacity and store/release thermal energy at a nearly constant temperature, relative low weight, small unit size and isothermal behaviour during charging and discharging when compared to the sensible thermal energy storage. PCMs are valuable only in the range of temperature close to their phase change point, since their main thermal energy storage capacity depend on their mass and on their latent heat of fusion. Selection of the proper PCMs is a challenging task because there are lots of different materials with different characteristics. In this research paper the principles and techniques of the Analytic Hierarchy Process (AHP) are presented, discussed and applied in order to prioritize and select the proper PCMs for comfort application in buildings. The AHP method is used for solving complex decisional problems and allows the decision maker to take the most suitable decisions for the problem studied. The results obtained reveal that the AHP method can be successfully applied when we want to choose a PCM for comfort application in buildings.
