Geothermal energy

Geothermal energy - a lucrative source of energy

Geothermal energy is a cheap source of energy that is becoming more and more state of the art. In addition, new developments in drilling technology and heat extracting methods foster the widespread market penetration.

The standard technology to exploit geothermal energy is based on vertically orientated boreholes. This is expensive, presupposes a well trained drilling team and very often causes damage to land and gardens. It’s therefore not surprising that drilling cost regularly represent more than 50 % of the entire investment, hindering potential customers from investing in geothermal heating systems.

The people behind the GRD method had these issues in mind. GRD is a patented, radial bore method where one central drill chamber is used to install borehole heat exchangers radially in all directions and angles of inclination, even under existing buildings. It’s similar to the roots of a tree: all its dimensions are used to provide sustaining and efficient energy supply.
