A MOLTEN SALT COMPOSITION FOR HIGH TEMPERATURE THERMAL ENERGY STORAGE

摘要

The present invention relates to a novel thermal storage material for use in thermal energy storage systems and process of preparation thereof. More particularly, the present invention provides a ternary salt composition for storage/transfer of thermal energy particularly as sensible heat having a melting point in the range of 138°C to 147 °C and thermal stability upto 700 °C. The present invention provides a salt composition for thermal energy storage which works on wider temperature range. The present invention provides a novel molten inorganic salt composite directed at improving the melting temperature range, cost and higher thermal stability upto 700 ºC, in order to compete more effectively with available molten salts for use in concentrated solar power plants.
