“…They developed a model which estimated the heat flow of the system and performed limited parametric studies. Their results, as well as results more recently from Nithyanandam and co‐workers show clearly that the least cost containment vessel designs still cost more than the salt . Thus, the optimization of the containment design is an important part of selecting the correct PCM.…”

“…[10] This solution optimizes the geometry of the design vessel for minimal cost based on the properties of the salt mixture, the HTF, and the target performance characteristics. As this can be a very computationally involved procedure for the number of mixtures tested, an analytic solution was developed.…”

“…Each PCM consists of several tubes which are finned or not as the configuration demands, with the geometry as shown. [10] w f is the fin thickness, w s is the length of the PCM layer in contact with outer wall of tube, r is the inner diameter of tube, R is the outer diameter of the tube, L is the length of the tube. Fluoride mixtures have been demonstrated to be effective for long lifespans, [37] but they must be of extremely high purity to do so.…”

“…The domination of the cost of the containment vessel, and the understanding that selection of salts requires this cost estimate, is a well understood phenomenon . Esen et al first articulated that PCM selection is a coupled problem involving the PCM properties and an optimized storage design .…”

For solar thermal power to be cost effective as a baseload generation paradigm, the cost and efficiency of every subsystem must be improved. To reduce the cost of thermal storage and increase the working temperature of the subsystems for greater efficiency, appropriate storage materials must be identified for study. Unfortunately, there is an enormous search space of salt mixtures that are suitable candidates for thermal storage and must be analyzed for cost effectiveness to determine which candidates are the best. To lessen the experimental burden, this article combines previously validated theories for estimating the properties of salt mixtures with an analytic design optimization method to better estimate the true cost of each candidate. Five hundred and sixty three binary, ternary, and quaternary mixtures are analyzed. Five mixtures are identified as the prime candidates for a cascaded latent heat thermal energy storage system for a supercritical CO2 Brayton cycle generator. This system is cheaper than the Sunshot Initiative cost targets, bringing the solar thermal paradigm into cost competition with fossil fuels.

“…Raud et al developed an analytical method for optimizing the design of tube and shell or tube and fin containment vessels for the least cost, subject to geometric and performance constraints. The optimization was used to investigate the relationship between optimal vessel geometry and configuration, fin properties, PCM properties, and cost.…”

This article reports detailed investigation of using different Phase Change Materials (PCM) in various designs of Thermal Energy Storage (TES) Devices: specifically, heat exchanger. The focus is on the performance analysis of different types of heat exchangers acting as TES having various PCMs which are substantially reviewed in this paper. The study highlights the difference in their geometry and performance output. Further, the importance of different performance enhancement methods with parametric study of different heat exchangers using PCM is described. From the detailed investigation, finally, it is realised that the different factors such as no. of outer tubes, no. of inner tubes, tube material selected, type of PCM, provision of an extended surface, use of different metal foams and nanoparticles, various types of composites, charging and discharging characteristics and packed and cascaded units are different heat transfer enhancement methods to improve the heat transfer. A novel kind of heat exchanger known as Webbed tube heat exchanger using PCM is discussed for an efficient TES unit. Further, a review of quantitative analysis of melting time, solidification time, charging and discharging time is discussed.
