2. The properties of solar thermal energy storage materials Applications like house space heating require low temperature TES below 50 °C, while applications like electrical power generation require high temperature TES systems above 175 °C .
The performances of solar thermal energy storage systems A TES system consists of three parts: storage medium, heat exchanger and storage tank. Storage medium can be sensible, latent heat or thermochemical storage material . The purpose of the heat exchanger is to supply or extract heat from the storage medium.
In high temperature side, inorganic materials like nitrate salts are the most used thermal energy storage materials, while on the lower and medium side organic materials like commercial paraffin are most used. Improving thermal conductivity of thermal energy storage materials is a major focus area.
