What is Thermal Energy Storage?
Thermal Energy Storage (TES) is a large-scale underground system designed to store thermal energy for long periods of time. The concept enables excess heat generated during periods of low demand to be stored and later supplied when energy demand increases, such as during winter months.
Why is large-scale energy storage needed?
As renewable energy production increases, energy systems face growing challenges related to balancing supply and demand. Thermal energy storage helps bridge seasonal gaps, improve energy efficiency, reduce waste heat, and support the transition to a low-carbon energy system.
Who are the typical customers?
Potential customers include:
- District heating companies
- Energy utilities
- Municipalities
- Property developers
- Industrial facilities with surplus heat
- Large energy consumers seeking long-term decarbonization solutions
