Geothermie

Our geothermal power station

The only geothermal power station in Europe is located in the east of Bad Blumau- here, energy in the form of heat and natural CO2 is extracted from the earth's mantle through a drilling process.

Vulkania® curative spring - with the power of the earth

The water of the Vulkania® curative spring completes a true circle - first the 107°C hot water of the Vulkania® curative spring is used to generate energy, then it flows back to the heat exchangers of Rogner Bad Blumau before it finally returns to the first borehole where it is injected back into the earth.

Natural carbon dioxide (CO2)

Over the past thousand years the Vulkania® water has been enriched with natural carbon dioxide. Today, the geothermal power station generates 1.1 tons of CO2 per hour and is used to regulate the pH-value of the water at Rogner Bad Blumau. The rest of the energy that is not being used is sold to various other industries.

Green Energy

Since August 10th 2001 Rogner Bad Blumau has been self-sufficient in generating its own power. The hot Vulkania® water creates steam that drives the turbine and the generator - that way, 190kW energy (on an annual average) can be produced.

Emission-free heating

Geothermal energy has been used to heat Rogner Bad Blumau since December 31st 2000. After generating power, the Vulkania® water still has a temperature of 85°C. This is sufficient to heat the facilities of Rogner Bad Blumau even at an outside temperature of 20°C. By using geothermal energy, 6,800l of heating oil can be saved per day in the cold season and it spares the environment 4,500 tons of greenhouse-gas. This has the same benefit for our climate as 2,700 cars less per year. The geothermal energy system of Rogner Bad Blumau is a showcase project not only for Europe, but the entire world. With this sensible and environmentally friendly way of using energy, Rogner Bad Blumau has a leading role in environmental awareness and protection.
