If at all possible, RDG foresees the reuse of reservoirs as sources of renewable geothermal energy after the production of conventional energy sources has ceased. Geothermal energy is stored below the earth’s crust in the form of heat, and is also known as geothermal heat. Modern systems can convert this heat into usable energy. In comparison with other renewable energy sources, the advantage of geothermal energy is that it is permanently available; no matter what the weather conditions or the time of day or year. This makes it possible to guarantee reliable and cost-effective energy supplies.
The deeper we penetrate below the earth’s surface, the hotter it gets. In our latitudes, the temperature increases at a rate of around 3°C for each additional hundred metres from the surface. The actual source of the heat is the earth’s core, where, according to latest estimates, the temperature is predominantly around 6.000°C. By human standards, this energy source is inexhaustible. We develop geothermal projects in close collaboration with the company RAG Austria AG, and thus contribute our experience as well as our ability to secure funding for turnkey geothermal projects.

Geothermal district heating has many advantages – for example, it not only reduces CO2 emissions, but is also efficient and is not affected by price fluctuations on the global energy market. Environmentally friendly geothermal energy is fully independent from the fluctuations that affect wind power and solar energy, is locally produced and used, and is transported invisibly underground. This keeps logistics to a minimum and thus minimises environmental impact.
