Predictable, cost-effective geothermal for heating, cooling and storage
Technology
Patented coaxial deep geothermal
QHeat’s technology enables industrial-scale heating, cooling, and thermal storage. By combining deep geothermal wells with heat pumps, the system delivers two advantages at once: predictable, efficient thermal energy and seasonal underground storage capacity.
At the core of the system is a purpose-engineered insulated inner pipe installed within the borehole. Each well field is designed to match the client’s thermal energy demand by optimising the number of wells, their depth and configuration. Standard implementations typically range from 1 to 2 kilometres in depth.
System capabilities
Heating, cooling, and seasonal storage - all in one well
Deep coaxial heat well
In heat extraction mode, cooled water is pumped down through the annulus of the well. As it descends, it absorbs heat from the surrounding rock, all the way to the bottom of the well.
The heated water rises through the thermally insulated collector pipe, minimizing heat loss. Coaxial design enables high flow rate, which improves efficiency. Heat pump then lifts the temperature to the needed end use.
Combined with a heat pump, a single 2 km deep QHeat well can deliver approximartely 1,5 GWh of heat annually. This is enough for 15,000 square meters of commercial or residential space.
Deep coaxial cooling and seasonal storage
During warmer months, the system provides cooling while dissipating heat from buildings and storing it underground.
Excess heat can be stored by pumping heated water through the thermally insulated collector pipe to the lower section of the well. As the water circulates, heat is transferred to the surrounding rock, allowing the well to function as seasonal thermal storage.
When heating demand rises, the flow direction is reversed and the stored heat is recovered at the surface.

Applications
Built for real-world energy systems
Waste heat recovery and reuse
Capture surplus heat from industrial processes, waste-to-energy plants or data centres, and store it underground for winter use.
Ideal for
- District heating networks
- Industrial parks
- Modular data centres
Benefits
- Reduced fossil-based peak production
- Higher overall system efficiency
- Support for district heating electrification
How it works
- Excess industrial heat is pumped into deep wells for seasonal storage
- Stored heat is extracted during colder winter months
- Heat pumps with high COP enhance the temperatures
Heating and cooling a block of buildings
Provide heating and cooling through a local low-temperature network. Geothermal wells and heat pumps supply energy, while data centres contribute surplus heat. A bi-directional network enables buildings to exchange and store thermal energy underground.
Ideal for
- Residential area developers
- Urban planners and property developers
- Energy companies
Benefits
- Highly efficient low-temperature distribution
- Lower emissions through electrified heating
- Enables scalable, future-proof urban energy systems
How it works
- Buildings exchange heating and cooling through a shared low-temperature network
- Excess heat is stored in deep geothermal wells and can recovered seasonally as needed
Heating and cooling industrial parks
Reuse surplus process energy within a shared local low-temperature network, transforming waste heat into a valuable resource.
Ideal for
- Industrial parks
- Industrial manufacturing companies
- District heating operators
Benefits
- Maximum reuse of industrial process energy within the local energy system
- Reduced emissions through decarbonised heating
- Greater efficiency, flexibility and energy resilience
How it works
- Excess process heat is captured and redistributed
- Energy is redistributed between facilities or stored in deep geothermal wells
- Stored heat is recovered when process or space heating demand increases
