Thermal energy storage refers to a power storage system that is used for transferring and storing energy obtained from ice, cold air or water for later usage. It includes sensible, latent and thermochemical heat storage that is based on molten salt, ice and miscibility gap alloy technology (MGA). Some of these solutions are used for storing hot or cold energy for powering electrical systems in commercial and residential complexes, while others are used for storing solar energy in the summers, which is further utilized in the winters. This aids in preventing the overutilization of conventional energy from the grid systems. 

Increasing emphasis on the utilization of renewable energy resources across the globe is one of the key factors driving the growth of the market. The growing demand for thermal energy storage systems in heating, ventilation and air conditioning (HVAC) technology for large-scale heating and cooling is also providing a boost to the market growth. Furthermore, concentrated solar power (CSP) is increasingly being integrated with the thermal energy storage systems to offer grid flexibility and minimize efficiency losses by generating electricity through dry cooling during lower ambient temperatures. Additionally, increasing environmental consciousness, coupled with the growing adoption of thermal energy storage for power generation in green buildings, is acting as another growth-inducing factor. Other factors, including the implementation of favorable government policies to promote sustainable infrastructural development, along with extensive research and development (R&D) activities, are projected to drive the market further.
