Thermal Energy Storage Market Segmentation:

End-user Segment Analysis

The global thermal energy storage market is segmented and analyzed for demand and supply by end user into residential, commercial & industrial, and utilities. Out of these, three end user of thermal energy storage, the commercial & industrial segment is estimated to gain the largest market share in the year 2035. The growth of the segment can be attributed to the increasing demand for energy for both industrial and commercial purposes. The global industrial sector's demand for power has grown by 3% since 2000. In addition, in 2021, retail power sales to businesses climbed by roughly 3%. Moreover, 0.14 trillion kWh, or nearly 3% of the total amount of energy, were used by the industrial and commercial sectors, worldwide.

Application Segment Analysis

The global thermal energy storage market is also segmented and analyzed for demand and supply by application into heating & cooling, and power generation. Amongst these two segments, the heating and cooling segment is expected to garner a significant share in the year 2035. The rejected heat from air conditioning units can be recovered using latent heat thermal energy storage devices, which can then be used to produce low-temperature hot water. Owing to the heat rejection from air conditioning systems, it reduces not only the amount of primary energy needed to heat residential hot water and also the damage to the environment. The growth of the segment is primarily attributed to rising demand for air conditioner. Almost 20% of the electricity consumed in buildings worldwide today is used by air conditioners and electric fans to stay cool. In addition to increasing emissions, the growing demand for space cooling is placing a tremendous amount of stress on the energy infrastructure of many nations. Moreover, over two-thirds of homes worldwide may have air conditioners by 2050. Together, China, India, and Indonesia will make up half of the total.
