Market Dynamics


The decarbonization process of the energy sector and depletion of carbon production with a view to cap the global climate alterations are some of the top goals for the governments, energy authorities, and industries worldwide. Accelerated utilization of renewables, clubbed with electrification and rising energy efficiency of electric grid, can be estimated to achieve over 90% of the energy-related carbon dioxide (CO2) emission reductions required. Due to a recovery in the hydropower sector, generation growth resumed to its long-term trend. Solar generation aims to grow strongly; in 2018, solar overpowered bioenergy to come out as the third largest source of renewable electricity generation. Thermal energy storage stocks solar thermal energy by heating or cooling a storage medium like rocks, water, sand and molten salt, with a view to use the stocked energy at a later stage for cooling and heating applications and power generation. Thermal energy storage is an integral part for electricity storage in concentrating solar power plants in which solar heat is stored for producing electricity when sunlight is missing. This promotes continuous operations of concentrated solar power plants. Some of the advanced CSP thermal energy storage technologies include two-tank indirect system, two-tank direct system and single-tank thermocline system. The benefits of thermal energy storage in CSP plants involve increase in overall efficiency, reductions in investment, better reliability, running costs, and economical operations. It decreases the emission of carbon dioxide. Thus, combining of thermal energy storage in CSP plants is foreseen to drive the market growth.


Competition between battery storage and pumped-storage proves to be a restraining factor for the market growth.

From two of the solutions available, being able to differentiate between the costs of battery and thermal energy storage, is vital for industries and power plant operators as far as deployment in the near future is considered. Choosing of the most suitable technology guarantees that the installation supports a commercial facility to utilise electricity in as cost-effective manner as possible. Batteries are used for supplying backup power for elevators, lighting and computers, on the other hand thermal energy storage is the easiest way of decreasing electric demand. Air conditioning market stands upto a third of energy costs in summer season and it can be very inefficient and costly to store energy in a battery just to have it converted yet again to generate instant cooling. On the other hand, the entire building load cannot be supported with only thermal storage.

Maximum battery storage projects that system operators (ISOs/RTOs) develop provide short-term energy storage and are not fit to replace the traditional grid. Lithium-ion batteries, which supply enough energy to shoot up the local grid for around 4 hours or less. These applications are used to provide relief to the energy grid in peak hours, for reliability and to integrate renewables.

Battery storage and pumped-hydro storage are considered over thermal energy storage due to their lower efficiency on the basis of economy. Thus, these alternatives act as obstacles to the growth of the thermal energy storage market.


Decentralization of renewable energy sector proves to be an opportunity. The deployment of decentralized renewable energy is encouraging a disrupting shift of the energy sector. The speedy development of decentralized renewable energy technologies is estimated to change the design of the energy sector in the direction of a multi-operator set-up where large utilities interact as far as captive consumers and mini-utilities are concerned. Power has been provided to 30% of the people who have gained access to electricity since 2000 through renewable energy which is distributed through the grid, mini-grids and off-grid installations. To gain 100% electrification by 2030, the contribution of decentralized renewable energy share will require to grow significantly.

Self-consumption, application of distributed storage and industrial bulk consumption will yield profits for both end users and the power system in a broader picture. Hence, thermal energy storage technology is estimated to gain opportunities in the forecast period.


Costly initial set-up rates varying with technology proves to be a challenge for the market growth.

The total cost of thermal energy storage technologies lies on size, application and thermal insulation technology. Costs of thermo-chemical storage-based thermal storage systems and phase change material are commonly higher in comparison to the cost of storage capacity they supply. The cost of storage systems includes approximately 30% to 40% of the total system cost. Subsequent research into energy storage technologies to calm down the upfront economical requirement is estimated to make thermal energy storage technologies more competitive in the forecast period.
