Market Trends

Major market trends in the thermal energy storage industry include the development of cost-effective phase change materials, integrated cooling and power technologies, and adoption of thermo-chemical energy storage. Additionally, the proliferation of waste heat recovery projects leveraging thermal storage is anticipated. Sustainable building codes focusing on energy efficiency will further drive residential and commercial installations.

Market Drivers

Two key drivers of the thermal energy storage market include increasing adoption of renewable energy and rising demand for efficient energy storage solutions. Renewable energy sources like solar and wind have intermittent capabilities which creates a need for energy storage technologies that can store excess energy and dispatch it when renewable energy is not available. Thermal energy storage provides an efficient way to store energy from renewable sources in a usable hot or cold form. Additionally, growing demand for improved grid reliability and energy security is also influencing more investment in thermal energy storage systems that can help balance energy supply and demand effectively.


One of the major opportunities for growth in the thermal energy storage market is its increasing role in district heating and cooling applications. As urbanization increases worldwide, more buildings and industrial facilities will need efficient heating and cooling solutions. Thermal energy storage when coupled with central heating and cooling plants can help reduce peak demand, utilize off-peak energy, and improve overall energy efficiency of district energy networks. This represents a huge potential market for companies to provide integrated thermal storage and district energy solutions to cities.

Key Takeaways

The thermal energy storage market is poised for strong growth over the next decade led by growing demand for renewable energy integration and efficient grid management solutions.

The market size is estimated to reach $5.67 billion by 2024 and global companies are expanding their operations across regions to tap the opportunities. Leading providers are also investing in new product innovations combining thermal storage with areas like solar thermal power plants, waste heat recovery, and district energy systems.

Technological advances aim to further increase storage capacities and discharge durations. Overall, thermal storage is expected to play a vital role in transitioning to a more sustainable, reliable and cost effective future energy system worldwide.
