The global thermal energy storage market size was evaluated at USD 23.48 billion in 2023 and is expected to attain around USD 50.57 billion by 2032, growing at a CAGR of 8.90% from 2023 to 2032. The increasing demand for heating and cooling applications for smart infrastructure is anticipated to drive the growth of the thermal energy storage market.
The thermal energy storage market deals with the storage of heat energy or energy from cold air, water, or ice. This method is built into advanced technologies that enhance energy solutions like hydro and solar. The increasing commercialization of CSP plants, increasing demand for electricity during peak hours, rising demand for thermal energy storage systems in HVAC, growing need for energy efficiency, and shifting preference towards renewable energy generation such as concentrated solar power is anticipated to drive the growth of the market.
The increasing desire for improved energy efficiency coupled with ongoing energy usage efforts are driving the enhancement of market growth. In addition, increasing environmental concerns, together with the rising integration of thermal energy storage for power generation, especially in green buildings, are further expected to drive the growth of the thermal energy storage market during the forecast period.
Potential construction cost savings fuel market growth
A properly designed and planned thermal storage system often offers lower costs in addition to lower energy costs and lower energy use. This is due to the smaller related infrastructure and smaller equipment requirements, which is possible with the extra costs of the thermal storage tank. The cooling production equipment cost is much less, and the building and electrical infrastructure supporting the cooling equipment is also lower, potentially more than balancing the country cost of the thermal storage system, therefore producing a non-storage system vs. net capital cost savings. In addition, lower maintenance costs, reduced energy costs, and reduced on-peak energy demand are further anticipated to drive the growth of the thermal energy storage market.
However, thermal energy is almost impossible to store in any transferred form or form in any other form that may restrain market growth. The very high amount of thermal energy storage is very unsafe and dangerous for humans. The high quantity of thermal energy in power plants needs a slow supply of combustibles. These create several environmental concerns because of the other dangerous gases and the production of greenhouse gases. The heated water utilized in thermal energy storage power plants can disturb the ecology and hurt the lives in the water. These major restraining factors may hinder the growth of the market.
