Technology
Mountain Battery™ is a thermal geostructure designed for crystalline bedrock. Through guided directional drilling and the creation of heat fins, a large underground thermal reservoir is formed — capable of storing heat at temperatures up to 250°C. This makes the solution ideal for:
Industrial waste heat
Solar thermal and wind power
Energy parks and industrial clusters
District heating systems — with or without heat pumps
Seasonal storage in Nordic climates
Powering cities municipalites and industries with sustainable thermal energy
Why Mountain Battery™ matters
Transition to thermal heating – reducing grid load
Mountain Battery™ enables large-scale thermal storage directly in crystalline bedrock, relieving pressure on the electricity grid and supporting the shift from electric to thermal heating.
Reduced nature impact
No land use, no excavation, no critical minerals. Just boreholes in the bedrock — providing energy storage with minimal environmental footprint.
Better use of surplus heat and solar thermal energy
Compared to other heat storage system, the system is more cost-effective, provides significantly higher
performance, and can be operated without heat pumps.
