Phase Change Materials (PCM) became one of the most interesting research directions toward improving the efficiency of concentrated solar power plants. Different methods were proposed to increase storage capacity as a result of the encapsulation protection and efficient thermal energy storage for high operating temperatures. Here, we present a soft chemical process to encapsulate inorganic KNO 3 as PCM system using nanostructured ZnO shell material, based on hydrothermal synthesis followed by spray drying and their thermal conductivity measurements are discussed. A unique micro-pilot equipment for the functional characterization of microencapsulated PCMs was designed and built for real time monitoring of thermal properties of these materials.
