How does it work?
The system stores thermal energy in a combination of water and surrounding rock formations. Heat is transferred into the storage facility during charging periods and later extracted through a network of tunnels and boreholes when needed.
Is the technology proven?
The design is based on established engineering principles and extensive thermal modelling. The heat transfer mechanisms in rock and water have been validated through comparable large-scale projects and independent technical reviews.
What can the energy be used for?
A typical TES facility can store between 50 and 500 GWh of thermal energy, depending on site-specific requirements and geological conditions. In practical terms, a TES facility of this size could supply a medium-sized city with renewable heat throughout the winter season, using energy that was captured and stored during periods of surplus production.
