About us

Ruden Energy

Ruden Energy provides clean, geothermal heating and cooling, and energy storage.

The LEAT concept delivers heating and cooling to buildings and infrastructure in a smarter and more efficient way than traditional well systems. HEAT and iHEAT enable the storage of waste heat or storage of energy from renewable sources.

Ruden Energy is the only supplier that delivers such concepts in Norway, based on their knowledge and experience of hydrogeology and applied technology. We have projects running from the greater Oslo area to Tromsø, and have the ambition to expand outside of Norway.

Innovative hydrogeology

Our energy concepts

Our energy concepts are based on the innovative utilization of hydrogeology. The core of all concepts lies in the circulation of water through enhanced fracture networks in the bedrock. LEAT is generating heating and cooling for buildings and infrastructure, using a heatpump, where HEAT and iHEAT are the natural scaling of this concept.

LEAT

Smarter heating and cooling of buildings and infrastructure

Ruden Energy has developed the Low Enthalpy Aquifer Technology (LEAT) system for heating and cooling large commercial and residential buildings. LEAT is also suitable for infrastructure facilities such as train stations and airports.

HEAT

Creating industrial sized “underground batteries” from waste heat

Ruden Energy created its HEAT concept to store and recover seasonal waste heat from industrial processes, turning bedrock into large-scale natural thermal batteries. The stored heat can be recovered whenever needed.

iHEAT

Underground energy storage for renewables

Ruden Energy is developing the iHEAT system for storing electricity from renewables, converted to heat, directly in the ground. If successful, it could be a game changer for clean energy supply.

'Da brønnparken kollapset, fant ingeniørene en langt bedre energi-løsning for Økern Portal'

This article describes how it was planned to provide the energy needs of the Økern Portal building in Oslo with 21 boreholes to 500m depth. During drilling it appeared to be very difficult to drill to these depths and Ruden Energy assisted in finding an alternative and smarter solution. Read about the collaboration of Ruden at the Økern Portal project in this article of Teknisk Ukeblad here (membership required).
