Product Type Insights

Sensible heat storage accounted for the largest revenue share of 50% in 2021. This can be attributed to rising demand for solar thermal systems, along with applicability across large scale HVAC systems. Provision of reversible charging and discharging facility for an infinite number of cycles is a key feature of the technology that will further enhance the product penetration.

The thermochemical heat storage segment is anticipated to exhibit the fastest CAGR of 17.8% over the forecast period. In this storage, the heat stored by different mediums is released when a reverse reaction takes place between them. Thermochemical storage systems provide high energy density as compared to latent or sensible heat storage systems. This form of heat storage is preferable for long-term storage as losses do not occur overtime, but only during charging and discharging phases.

Technology Insights

Molten salt technology occupied the largest revenue share of 84.8% in 2021 and is expected to witness significant growth over the forecast period. The growth of the segment can be attributed to its high technological efficiency, along with its usage in several solar energy projects. Molten salt is used to store the heat collected by means of solar troughs and solar towers. The heat collected by means of this technology is used to enable steam turbines by converting it to superheat steam.

Ice-based technology is anticipated to grow at a significant rate over the forecast period. Ice is used in ice storage air conditioning for the storage of thermal energy. The process is highly feasible as the heat of fusion of water is sufficiently high and can contain approximately 317,000 BTU or 334 mega joules (MJ) of energy in one metric ton of water. This energy is equivalent to approximately 26.5 ton-hours or 93 kWh. This application can be utilized to provide chilled water and air conditioning to a large number of commercial and residential buildings.

End-user Insights

The industrial segment accounted for the largest revenue share of 40% in 2021 and is projected to maintain its lead over the forecast period. Rising spending on infrastructure development and establishment will propel the demand for HVAC systems, which, in turn, will drive the industrial segment. Furthermore, growing adoption of these systems across several industries using large quantities of hot water for economic purposes will boost the segment growth.

The utilities segment is expected to witness the fastest growth over the forecast period. The segment comprises public services, such as broadband internet, transportation, telephone, sewage, water, natural gas, and electricity. Thermal energy is utilized to provide these public services at an extremely low cost. Cogeneration plants are employed to derive thermal energy and then convert it to the required form of energy.

The residential and commercial segment held a significant market share in 2019. Thermal energy plants are utilized to generate electrical energy to suffice the energy demand of the residential and commercial sectors. Electrical storage heaters and home storage units are also employed to store thermal energy in order to provide residential and commercial buildings with heating and cooling capacity as required.

Storage Material Insights

Molten salt accounted for the largest revenue share of 55.0% in 2021 owing to its usage as a thermal energy storage medium across several applications, including concentrated solar power plants. The molten salt stores solar energy for longer durations, thereby overcoming the short energy cycle restraint of thermal energy storage. Growing demand for concentrated solar power technology is expected to positively influence the TES market growth.

Water is the most commonly utilized material to store heat energy as it has a heat capacity of 4.2 J/(cms.K), which is considered to be one of the highest. It is often utilized in systems such as heat storage tanks, pebbles, concrete, and hot rocks. The steam generated is then utilized to power the turbines, which eventually generate low cost and efficient electricity.

Application Insights

The district heating and cooling segment accounted for the largest revenue share of 60% in 2021. The application of district cooling and heating is utilized to distribute the generated power in order to suffice commercial and residential requirements. This distributed energy is utilized for water heating, space heating, and air conditioning. The stored power is derived in cogeneration plants by burning biomass and fossil fuels. Various systems utilized for the generation of energy for district heating and cooling applications include central solar power and boiler stations.

The power generation segment is anticipated to witness the highest growth over the forecast period. Rising demand for uninterrupted and cost-efficient power supply from off grid and remote areas will drive the segment. Introduction of several government schemes regarding electricity generation from solar power plants will boost the power generation segment growth. The renewable power generation supplier receives retail electricity price for each unit generated and the extra power sold back to the grid under the feed-in tariff scheme.

Thermal energy is utilized for process heating and cooling application in order to change the chemical and physical properties of the desired material. Heat treatment is utilized for metalworking, industrial, and manufacturing processes. These processes require extreme cooling and heating in order to harden or soften the desired material. Various types of process include quenching, normalizing, tempering, strengthening, precipitation, case hardening, and annealing.

Regional Insights

Europe accounted for the largest revenue share of 37.6% in 2021 and is projected to maintain its lead over the forecast period. The region is characterized by a large number of thermal energy storage systems, which are utilized for space heating, water heating, district heating and cooling, and power generation.
