An Underground Energy Bank
TES stores energy in a carefully engineered underground structure consisting of tunnels, boreholes, water and bedrock.
Using natural thermal stratification, the system stores different temperature levels efficiently and makes them available when required.
The result is a highly efficient and scalable storage solution for cities and regions.
A Simple Comparison
An ordinary thermos keeps warm for a few hours.
TES can store thermal energy for years.
