The geothermal power plant Braunau-Simbach in the Bavarian town of Simbach am Inn is a hydrothermal geothermal heating power plant . The underground parts of the plant are partly located under the Austrian Braunau am Inn . The operator is E.ON Bayern .
history
In 1996, the German city of Simbach am Inn, the Austrian city of Braunau am Inn and the Rottal-Inn district developed plans for a geothermal district heating plant in cross-border cooperation . To this end, two project companies were founded in 1997. The first wells took place in 1999. Construction of the district heating network and the associated heating center began in 2001. Trial operation began at the beginning of 2001. In autumn 2001, the plant was finally completed and put into operation. The district heating network was only completed in 2005. In 2009, as part of a Europe-wide research project, the system was expanded with a turbine from the Italian manufacturer Turboden , which works according to the Organic Rankine Cycle (ORC) process.
technology
The facility is located in the Bavarian Molasse Basin . In order to make use of the geothermal potential at the site, a production well (1900 m deep) and a reinjection well (1850 m deep) were built into a Malmkarst layer. In order to enable hydraulic and thermal decoupling of the production and re-injection wells, the wells were not carried out parallel to one another: While the holes on the surface of the earth are 15.5 m apart, this distance increases underground to 2050 m. For this purpose, the production well was deflected by 66 degrees. The production well runs under the Inn and the end of the production well is on the Austrian side under the city of Braunau.
Thermal water with a temperature of 80 ° C and a volume flow of 74 l / s (= 266 m³ / h) is pumped through the well. The heat of the thermal water is used, then the water is pumped back into the ground through the re-injection well. The thermal water can provide a geothermal output of 7 megawatts . The district heating network is 35 km long and supplies 750 buildings with a total of around 5,000 to 6,000 households. The connected load of the district heating network is 40 MW.
In addition to providing district heating, this heat is also used to drive the ORC turbine with an electrical output of 200 kW.
environment
According to the project company and the operator, 10,700 to 16,000 tons of carbon dioxide emissions and 7 tons of sulfur dioxide and nitrogen oxide emissions are avoided each year . According to calculations by the Climate Alliance , this corresponds to an annual oil saving of eight million liters of oil.
