The growth of the thermal energy storage system's market is driving due to decreasing complexity in construction of thermal energy storage systems , increasing gas and electricity prices in major market such as Germany, France, UK, the USA and others are driving the TES market

Drivers:

• Increasing demand for heating, ventilation, and air conditioning (HVAC) technology in industries, commercial, and utilities.
• Increasing demand for district heating systems in educational institutions, group houses, hotels and others are driving the market.
• Growing demand for waste heat processing systems in various markets such as mining, chemical, petroleum and power plants.

Thermal energy storage (TES) systems are temporary storage of energy by cooling or heating a storage medium so that the stored energy can be used later for power generation, heating, and cooling applications.

Thermal Energy Storage in district cooling and heating systems serves as a reserve of thermal energy, which can supply cool or heating loads in times of peak demand or high electricity prices. Thermal energy storage (TES) is a technology that can solve the existing mismatch by recovering the industrial waste heat and storing it for later use.

Concentrated solar power plants (CSP) help stock up solar energy by using a storage material, such as water, molten salt, and rock, increasingly combined with thermal energy storage (TES) systems to offset the required cooling/heating demand.

The advantages of CSP thermal energy storage technology include reliability, efficiency, reductions in investment and running costs, reduced carbon dioxide emissions, and economic operations. 

Some of the Supportive Policies:

• European heat mandates to adopt full or partial bans on fossil fuels to heat buildings.
• California (United States) was the only jurisdiction to introduce a new technology mandate for renewable energy in buildings in 2019. However, policies prohibiting fossil fuel use for building heat can encourage the adoption of renewables and are the main factor driving the electrification of building heating.
• France, Mexico, the USA, and Japan announced financial support for solar thermal energy for dedicated water heating for commercial and industrial buildings.
• Austria, Norway, Germany, California banned the installation of liquid or solid fossil fuel boilers in new buildings from 2020.

Thermal energy storage (TES) can help balance energy demand and supply it on a daily, weekly or seasonal basis. As a result, it helps to increase power generation from renewable energy sources. It can also reduce peak demand, energy consumption, CO2 emissions and increase energy systems' overall efficiency.

Value Proposition:

• The essential flexibility to integrate high shares of wind and solar power.
• It can reduce the carbon footprint in industries and commercial buildings by heating and cooling.

Operational necessities of a Thermal Energy Storage (TES) System: 

• A pump is a mechanical machine used to raise or transfer fluids using suction or pressure.
• A temperature sensor is a sensor used to measure the system's temperature.
• Pipes to transfer hot water and electrolyte.
• Tanks to store the electrolyte and water
• A valve controls and regulates the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening and closing.
• Heat exchangers transfer heat from one medium to another.

Thermal Energy Storage Market Challenges:

• High capital cost compared to solar PV

Thermal Energy Storage Market Opportunities: 

• Defer T&D system
• Increasing demand for cold transportation, cold storage for agricultural products, Vaccines, etc.
• Growing demand thermal energy storage systems in electric vehicles
• Markets with growth potential are Brazil, Cyprus, Denmark, Greece, South Africa, Oman, China, USA, Australia, Austria, India, Germany, Israel, Italy, Poland, and Switzerland.

Thermal Energy Storage Market Restraints:

• Lack of Policy for decarbonization of heat/cool.
• High Initial Cost
• Skilled labour
• Accidents during construction.
• Competition from batteries and pumped hydro.

Molten salts are the most commonly used thermal storage material for large scale thermal energy as these have higher boiling points, high volumetric heat capacities, and low cost. When energy is needed, the molten salt is pumped into a steam generator that boils water, spins a turbine, and generates electricity.

Utilities are expected to hold the largest growth rate of the global thermal energy storage market during the forecast period. Thermal energy storage systems are integrated with electric utility plants, IPP, industries as a viable demand-side management option. These systems use heat, ice, or chilled water technologies for storing thermal energy in tanks during off-peak hours. This helps meet the peak demand with storage by shifting consumers' power demand to off-peak hours. In addition, many utilities currently offer timely pricing to their customers and sell power at a lower price during off-peak hours. 

Some of the Recent Developments :

• In Mar 2019, Climate Change Technologies had manufactured a modular thermal energy storage unit that accepts any electricity- solar, wind, etc. and uses it to heat up and melt silicon in a heavily insulated chamber.
• In May 2019, Vattenfall, a leading European energy company, and a Swedish company SaltX Technology commissioned an industrial scale pilot to test nano-coated salt-based energy storage technology, which enables thermal energy to be stored chemically and provides a long term solution. 
• In May 2019, Azelio unveiled its storage technology, which features a Stirling engine for dispatchable electricity production. Electricity from a wider range of renewable sources can be received and stored as thermal energy.   
• In 2019, Abengoa installed a 100MW CSP plant with a thermal storage capacity of 17.5 hours.
• In 2020, Abengoa commissioned a desalination plant in Rabingh to produce desalination water by using thermal energy storage.
