What Is Covered Under Molten Salt Thermal Energy Storage Market?

Molten salt thermal energy storage (TES) is a system that uses molten salts to store thermal energy at high temperatures, typically for use in concentrated solar power (CSP) plants. Molten salts are heated by solar energy and can retain heat for long periods, allowing the stored energy to be converted into electricity even when sunlight is not available. This technology improves the efficiency and reliability of renewable energy systems by enabling energy supply during peak demand periods or after sunset. The main types of molten salt thermal energy storage are sensible heat storage, latent heat storage, and thermochemical heat storage. Sensible heat storage involves storing thermal energy by raising the temperature of a material. The technology includes parabolic troughs, power towers, and fresnel reflectors, and the different applications are heating, ventilation, and air conditioning (HVAC) systems, heat transfer fluid systems, combined heat and power generators, and others. It is used by various end-user industries such as energy generation, residential, commercial, and industrial.

What Is The Driver Of The Molten Salt Thermal Energy Storage Market?

Growing demand for renewable energy is expected to propel the growth of the molten salt thermal energy storage market going forward. Renewable energy is energy derived from natural sources that are continuously replenished. The demand for renewable energy is driven by the need to reduce greenhouse gas emissions, combat climate change, and transition to sustainable energy sources that are cleaner, more efficient, and less harmful to the environment than fossil fuels. Renewable energy uses molten salt thermal energy storage to store excess thermal energy generated from sources such as concentrated solar power, enabling continuous energy supply even when the sun isn’t shining, thus enhancing efficiency and reliability. For instance, in September 2024, according to the Energy Information Administration (EIA)), a US-based government agency, renewable energy accounted for approximately 9% (8.2 quadrillion BTUs) of total U.S. energy consumption in 2023. The electric power sector consumed about 39% of this renewable energy, with renewables contributing around 21% to the nation’s electricity generation. Therefore, the growing demand for renewable energy is driving growth in the molten salt thermal energy storage industry.
