The global thermal energy storage (TES) market was valued at USD 4.1 billion in 2019 and is projected to grow at a compound annual growth rate (CAGR) of 9.45% from 2020 to 2027. The growing shift towards renewable energy generation, particularly in concentrated solar power, and rising demand for TES systems in HVAC (heating, ventilation, and air conditioning) are among the key factors driving the growth of the market. Additionally, the increasing need for energy efficiency, coupled with the ongoing global efforts to improve energy utilization, is expected to positively influence the demand for TES systems.

For example, in September 2018, the Canadian government updated its Commercial Energy Conservation and Efficiency Program, offering USD 15,000 worth rebates for energy upgrades in the commercial sector, encouraging the adoption of more energy-efficient systems like TES.

The U.S. is expected to see substantial growth in TES installations, owing to the growing number of thermal energy storage projects across the country. As of 2018, the U.S. accounted for 33% of the 18 under-construction TES projects globally and 41% of the total 1,361 operational projects, highlighting its significant role in the global TES market. The presence of key industry players in the U.S. is also expected to further boost the growth of the TES market.

The U.S. Department of Energy (DoE) evaluates TES systems based on criteria like safety, reliability, and cost-effectiveness, ensuring they adhere to strict environmental regulations and industry standards. The increasing emphasis on clean energy is prompting governments worldwide to invest in innovative energy storage systems to drive the transition towards renewable energy.
