Thermal energy storage (TES) is a technology designed to capture and store heat or cold for use at a later time, helping to balance energy supply and demand. It utilizes methods such as sensible heat storage, latent heat storage with phase change materials, and thermochemical storage to absorb excess thermal energy during periods of low demand and release it when needed. TES plays a vital role in enhancing energy efficiency, supporting the integration of renewable energy sources, and lowering operational costs across a range of applications, including building climate control, industrial processes, and large-scale power generation.
Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report's Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.
The primary product types of thermal energy storage include sensible heat storage, latent heat storage, and thermochemical heat storage. Sensible heat storage involves storing and releasing heat by changing the temperature of a material without altering its phase. TES technologies include molten salt systems, electric thermal storage heaters, solar energy storage systems, ice-based technologies, and miscibility gap alloy technology. Common materials used for storage include water, molten salts, phase change materials (PCMs), and other specialized substances. Applications of TES span power generation, heating, and cooling, and it serves various end-user sectors such as utilities, commercial enterprises, and industrial facilities.

This thermal energy storage market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenarios of the industry.
The thermal energy storage market size has grown rapidly in recent years. It will grow from$5.77 billion in 2024 to $6.55 billion in 2025 at a compound annual growth rate (CAGR) of 13.5%. The growth during the historic period can be attributed to the increasing demand for energy efficiency, the rising adoption of renewable energy sources, higher electricity costs, supportive government incentives and policies, and the growing need for effective peak load management.
The thermal energy storage market size is expected to see rapid growth in the next few years. It will grow to$10.80 billion in 2029 at a compound annual growth rate (CAGR) of 13.3%. The growth during the forecast period can be attributed to the increasing demand for energy storage in smart grids, a heightened focus on achieving carbon neutrality, growing investments in sustainable infrastructure, rising adoption of electric vehicles with thermal management requirements, and the need for resilient energy solutions. Key trends anticipated in the forecast period include the development of advanced phase change materials, high-efficiency molten salt storage systems, integration of artificial intelligence for energy optimization, the emergence of hybrid thermal storage solutions, nanotechnology-enhanced storage materials, and the advancement of smart thermal grids.
The rising demand for renewable energy is expected to drive the growth of the thermal energy storage market in the coming years. Renewable energy, derived from natural sources that are consistently replenished, such as sunlight, wind, water, geothermal heat, and biomass, offers an environmentally friendly alternative that helps reduce greenhouse gas emissions. The demand for renewable energy is largely driven by the need to mitigate greenhouse gas emissions, which are major contributors to climate change. This has led governments and industries to prioritize cleaner, more sustainable energy solutions. Thermal Energy Storage (TES) plays a crucial role in improving the reliability and efficiency of renewable energy by storing excess heat generated during peak production periods, making it available when energy demand is high or supply is low. For example, in December 2024, Eurostat, a Luxembourg-based government agency, reported that renewable energy accounted for 24.5% of the energy consumed in the European Union in 2023, up from 23.0% in 2022. As such, the increasing demand for renewable energy is fueling the growth of the thermal energy storage market.
Key players in the thermal energy storage market are focusing on developing cutting-edge solutions, such as next-generation energy storage systems, to improve energy efficiency, reduce carbon emissions, and aid the integration of renewable energy sources into the power grid. Advanced technologies, such as solid-state and flow batteries, are playing a crucial role in thermal energy storage applications by efficiently storing excess heat and releasing it when required, thus enhancing overall energy efficiency. For instance, in February 2025, Brenmiller Energy Ltd., an Israel-based thermal energy storage company, launched the bGen zero thermal oil (ZTO) solution, an innovative thermal energy storage system designed to electrify thermal oil heating in industrial applications. This system utilizes renewable electricity to charge and store thermal energy in crushed rocks, later transferring it to thermal oil at up to 340°C with high efficiency, providing a sustainable, zero-emission alternative for industrial heating.
In October 2024, TEXEL Energy AB, a Sweden-based thermal energy storage company, acquired all Stirling engine-related assets and thermal energy technologies from Azelio AB for an undisclosed amount. This acquisition strengthens TEXEL Energy AB's thermal energy storage capabilities, incorporating Stirling engine technology to enhance renewable energy solutions. Azelio AB, also based in Sweden, specializes in long-duration storage solutions using Stirling engine technology to convert stored thermal energy into electricity.
