Utilization of geothermic heat from thermal water in Straubing - Phase 2E, 3A and 3B

Description: Das Projekt "Utilization of geothermic heat from thermal water in Straubing - Phase 2E, 3A and 3B" wird vom Umweltbundesamt gefördert und von Stadtwerke Straubing GmbH durchgeführt. Objective: Extraction of energy from thermal water and substitution of fossil fuels for the heat supply of business centres, apartments and office buildings, sanatoria and bathing establishments, agriculture and fish-farming. The dimension of the project will be of a novel type. The thermal water of phase II, with 30 m3/h cooled down to 12 degree C, will be mixed with the large geothermal water stream for Phase III. A commercial utilization by extension of the existing local heat system and by inclusion into a demonstration project for efficient energy production and energy utilization, supported by the State of Bavaria, has already been started. The thermal water with a temperature of 35 degree C shall be conducted through future building areas by a new type of single pipe system, monitored by leakage-sensors. the heat is generated by heat pumps and will be used for the heating of business centres, apartment and office buildings, etc. the extensive utilization of geothermic heat has not been attempted until now. General Information: From the location of the production well (800 m deep), the thermal water (36 degree C) is to be conducted through future building areas past various heat consumers such as bathing facilities and sanatoria by means of a single-pipe system. The thermal water should also be conducted along agricultural operations and finally to a fish farm. For technical reasons the re-injection drilling must be located an adequate distance (2 km) from the production drilling so that the thermal water itself does not cool down (doublet method of construction). On its way from the production well to the re-injection well, a part of the thermal water flow will be cooled down in each of the central stations of the heat consumers by means of heat pumps. The water that has been cooled down in this way is then returned to the main pipe. The resulting mixed temperature, which is obviously less than the required 36 degree C, is conveyed to the next heat consumer. This process is repeated until all predetermined heat consumers are provided with geothermal heat. In this way the thermal water is cooled down to ca. 13 degree C and returned to the re-injection well (840 m deep). The heat is withdrawn from the thermal water by cascading. The total available geothermal heat capacity was calculated at 8 MW. A new type of absorption heat pumps will be employed. The pumps can completely do without the ozone-destroying CFC as coolant. This project will be further realized in phase III a and III b. The project will obtain EU-wide significance. Prime Contractor: Stadtwerke Straubing; Straubing; Germany.
