Thermal Energy Storage Global Market Insights 2025, Analysis and Forecast to 2030, by Market Participants, Regions, Technology, Application

Thermal Energy Storage Market Summary

Thermal Energy Storage (TES) systems store thermal energy for later use, enabling efficient energy management in heating, cooling, and power generation. The industry is defined by its role in decarbonizing energy systems, leveraging materials like molten salts and water tanks to shift energy loads and integrate renewables. The European Association for Storage of Energy notes that half of European energy consumption goes to heating and cooling, with around 89% supplied by fossil fuels, notably natural gas. Gas consumption shifted significantly since the invasion of Ukraine and the ensuing energy crisis. The International Renewable Energy Agency (IRENA) projects that by 2030, the global TES market could triple, growing from a few gigawatt-hours (GWh) in 2019 to over 800 GWh, with investments in cooling and power applications reaching USD 13 billion to USD 28 billion. Molten salt storage is widely used in the power sector, while water tank thermal energy storage (WTTES) dominates the building sector globally.
