Molten salt is a mixture of 60% sodium nitrate and 40% potassium nitrate; it stores energy at 566oC in a hot molten salt storage tank for use any time until electricity is needed, i.e. day or night, in the presence or absence of sunlight, during off-peak/normal operation hours or peak hours. Storage of energy in molten salt increases the overall reliability of solar plants and enables them to operate 24/7, providing base load power for both on-grid and off-grid applications. Molten salt increases the net annual output of a solar energy plant, helps avoid high fuel costs, and facilitates continuous power generation.

Increased adoption of renewable energy sources for power generation and growing demand for efficient, reliable, and price-competitive electricity are some of the factors boosting the growth of the market. Molten salt thermal energy storage allows solar plants to be designed in such a way that they optimize the electricity load profile according to the market fluctuations in terms of electricity demand. Some of the characteristics of molten salt are high energy density, low melting point, and low power generation costs as compared to those of oils, rocks, and concrete.

Molten salt has low vapor pressure and acts as a storage medium with large storage temperatures of up to 500oC. Molten salts are environment-friendly and cheaper than the synthetic oils that are currently used in power generation applications. However, heat sources such as electric heating or fossil fuels are required to maintain the high temperature of molten salt when solar power is unavailable due to poor weather conditions.
