Providing heat from deep energy wells

Heat from deep under the earth’s surface can deliver energy to almost all buildings and facilities – including to prevent icing at airports.

At a glance

  • Geothermal heat for buildings and public spaces
  • Deep wells deliver local and emission-free power
  • Ideal replacement for electricity for providing low-temperature heat

The solution is commercially available, but not necessarily immediately deliverable.

Electricity and gas are widely used to produce heat at low to moderate temperatures, including in outside areas in winter.

Electricity, however, is expensive and a high-quality form of energy. For many purposes, quality of this kind is not necessary, and energy could be better provided from cheaper, local sources.

Stable energy source

Energy wells are local, renewable energy sources with minimum environmental impact. They can replace electric or gas power as a source of heat for a number of applications.

To provide heat, Rock Energy drills deep energy wells to depths of between 800 and 3 000 metres. Clean water is circulated down the well and warmed up by the earth’s natural heat.

Rock Energy is also developing deep energy well systems for depths down to 5–6 000 metres. They will provide energy for larger facilities, such as district heating, industrial parks and airports. The aim is for the concept to be realised within the next three to five years.

During operation of all Rock Energy wells, there are no emissions to air, water or soil – and the plants operate 24/7 with an expected lifetime of 50+ years.

Concrete benefits

Deep energy wells from Rock Energy produce between 0.3 and 20 GWh of energy, ideal for medium-sized energy users. Hospitals, offices, car parks or sports arenas can use these wells to disconnect from the grid and become self-sufficient in energy.

The system can be combined with shallow 250-metre wells to also meet cooling needs for other installations.

All Rock Energy systems are modular and can be designed and expanded to meet the energy requirements of various energy users as they grow.

Market potential

Local, geothermal energy could be a widespread replacement for electricity from the grid for medium to large buildings and public spaces. It offers predictable prices, as well as long and stable operation.

When fully developed, Rock Energy’s deep energy well system could provide up to 150 GWh for users interested in independent energy production.
