Abstract The pursuit of CO2 reduction targets has increased the need of storage capacities for renewable energy or thermal energy to enhance the efficiency of industrial processes. To combine the benefits of latent and sensible thermal energy storage systems the concept of micro encapsulated phase change material is presented. The microparticles are designed to work in an high temperature thermal energy storage system considering economic and technical points of view. Therefore, particles of sodium nitrate are physio-mechanical coated with polyimide by using spray-drying in a fluidized bed reactor. To evaluate the influence of the process conditions several coating experiments with different process settings are performed. Afterwards the samples are analyzed to determine their properties. Besides a microscopic and a sieving analysis they are tested in the laboratory to define their mechanical and thermal limits. Finally, a rough layout of a thermal energy storage system using the produced particles is presented and compared to a common sensible thermal energy storage.

Thermal energy storage in the form of latent heat of fusion of phase change material gained considerable attention in solar energy applications since it significantly increases the energy density and reduces the storage tank size compared to the sensible heat storage system. Several numerical and experimental studies have been conducted to enhance the performance of the system. In this study, 2-D continuous solid phase and effective packed bed models are developed to study the behavior and performance of a thermal energy storage system for high temperature applications, which is composed of spherical capsules encapsulated by phase change material (Sodium nitrate) and high temperature synthetic oil (Therminol 66) as heat transfer fluid. Temperature distribution, fluid flow, melting, solidification and thermocline behavior of the system are predicted and the influence of capsule size on the performance of the system is studied.
