Market Overview:


According to a new report by IMIR Market Research on Global Thermal Energy Storage Market was valued at approximately USD 5.7 Billion in 2023. Over the course of the forecast period (2024–2031), the market is expected to develop at a compound annual growth rate (CAGR) of 9.45%, reaching a value of USD 9.74 Billion by 2031.

The market is growing due to a number of factors, including a shift in consumer preferences toward renewable energy sources like concentrated solar power and an increase in the need for thermal energy storage (TES) devices in HVAC systems. The market for thermal energy storage will be positively impacted by the ongoing attempts to maximize energy consumption and the growing need for improved energy efficiency. For example, the Canadian government amended its "Commercial Energy Conservation and Efficiency Program" in September 2020, offering cash incentives up to $15,000 for energy renovations in the commercial sector.

Thermal energy storage systems are assessed by the U.S. Department of Energy (DoE) based on their cost-effectiveness, safety, and compliance with industry and environmental standards. Additionally, it was mentioned that compared to North America, Europe & the Asia Pacific region had higher percentages of grid energy storage. Governments everywhere are working to create cutting-edge energy storage technologies as the need for renewable energy in the future grows.

Energy storage at a reasonable cost is the main issue facing the thermal energy storage industry. The application of lithium-ion batteries has been a significant development in this field. These batteries are known for their high energy density and long lifespans—500 deep cycles, or how many full charges from 20% to 100% can be made of them before performance starts to decline. They can also be used in power generating, district heating and cooling, and electric cars.

The COVID-19 pandemic lockdown led to a temporary prohibition on import and export, as well as manufacturing and processing activities across a range of businesses and electrical utilities. This reduced consumer demand for power. Furthermore, it is anticipated that the pandemic will hinder market growth due to a halt in the installation and construction of fresh electric utility infrastructures, energy-efficient power plants, grid networks, and other power plants due to a shortage of labor and an increase in the demand-supply gap. The market growth for thermal energy storage decreased as a result in 2020's second, third, and fourth quarters. The worldwide economy is anticipated to strengthen with the start of COVID-19 immunization in several economies, which led to a rebound in the thermal energy storage market after the second quarter of 2021.

Adoption of Innovative Storage Technologies

  • The growing usage of cutting-edge storage methods, such as phase change materials (PCMs), molten saltwater, and thermochemical storage, is propelling the market in thermal energy storage. Higher energy density, better thermal performance, and longer-lasting storage capacities are just a few of the advantages that these cutting-edge storage technologies have over conventional sensible heat storage systems. Phase change substances, for instance, can store energy well with little temperature swings because they can shift from a solid to a liquid or vice versa while absorbing or exchanging latent heat. In contrast, systems that store thermal energy at excessive temperatures for lengthy periods of time make use of the large thermal conductivity of molten salts. Thermochemical storage systems have a high energy density and are scalable because they store and release heat energy through chemical reactions.  The adoption of these technologies is anticipated to increase as research and development activities continue to advance them and bring down costs, hence influencing the market conditions in the Thermal Energy Storage Market.
Market Restraining Factors-

Technologies for storing thermal energy require complex infrastructure and machinery, such as control systems, heat exchangers, insulation, and storage tanks. When it comes to large-scale thermal energy storage projects that serve commercial or industrial enterprises, the initial expenses of designing, engineering, acquiring, and installing these components can be high. The precise specifications of every project, such as site parameters, system capacity, and connection with preexisting infrastructure, might further raise the required investment amount. High initial investment costs, particularly in areas with limited access to government incentives or finance, may discourage prospective investors and project developers into pursuing thermal energy storage projects. The adoption of thermal energy storage technologies must be accelerated by addressing cost obstacles through technological breakthroughs, economies of scale, and financial incentives.
