“…Thermal energy storage (TES) is a key component in the optimization of industrial processes, in applications with intermittent thermal energy generation, such as solar thermal systems or waste heat recovery, for which a suitable thermal storage system is essential [1]. TES systems have been developed as useful engineering solutions to reduce the gap between energy supply and demand in cooling or heating applications by storing extra energy generated during peak collection hours and dispatching it during off-peak hours [2,3]. Large-scale applications such as power plants, geothermal power units, nuclear power plants, smart textiles, buildings, the food industry and solar energy capture and storage are ideal candidates for TES systems [4].…”

Thermal energy storage (TES) plays an important role in industrial applications with intermittent generation of thermal energy. In particular, the implementation of latent heat thermal energy storage (LHTES) technology in industrial thermal processes has shown promising results, significantly reducing sensible heat losses. However, in order to implement this technology, a proper selection of materials is important. In this study, a new multi-criteria phase change material (PCM) selection methodology is presented, which considers relevant factors from an application and material handling point of view, such as hygroscopicity, metal compatibility (corrosion), level hazard, cost, and thermal and atmospheric stability. The methodology starts after setting up the system requirements where the PCM will be used, then a material screening is able to find all possible candidates that are listed with all available properties as listed before. Then, a color map is produced, with a qualitative assessment of material properties drawbacks, hazard level, melting enthalpy, and price. The experimentation starts with a preliminary set of tests on hygroscopicity and one-week corrosion test, which allows disregarding PCMs and selecting a short list of potential PCMs that would need further characterization before the final selection.
