| Abstract | After two successful drillings at Unterhaching a power ? heat coupling station is in construction. The aim is to convert the energy of the thermal water into electrical energy with a Kalina cycle power station and to use parallel the geothermal energy for district heating. The temperatures and flow rates in the two wells for production and injection are tested. The tests show temperatures of more than 122? C and a productivity as well as injectivity index of more than 200 [m?/h/MPa] respectively 300 [m?/h/MPa]. These results enable to operate an electrical power station of 3.35 [MWel] and to use about 40 [MWth] for district heating. With an optimal controlled operation of the power ? heat coupling system a reduction of 40,000 metric tons of the CO2 emission per year can be reached. |
