Summary
Taking advantage of the disparity in heat consumption between Summer and Winter, a huge facility capable of holding over a million cubic meters of water at 140°C, is being built in the Finnish city of Vantaa.
To borrow from Wikipedia: Thermal energy storage is the storage of thermal energy for later reuse. Employing widely different technologies, it allows surplus thermal energy to be stored for hours, days, or months. Scale both of storage and use vary from small to large – from individual processes to district, town, or region.
The seasonal thermal energy storage facility will be built in Vantaa’s bedrock, 100m below ground. Three caverns will be excavated, creating a space twice the size of Madison Square Gardens. These will be filled with hot water. Pressure will be created within the space, allowing the water to reach temperatures of up to 140 degrees without it boiling or evaporating.
The stored heat will be used to supply the district heating network whenever needed.
