supported by | | Deepest CO2 borehole heat exchanger in the world under testingFeb. 04, 2008 - On 22 January 2008 the German electric utility EnBW Energie Baden-Württemberg AG started officially operation of a 250 meters deep CO2 borehole heat exchanger in Triberg, Germany. This is the worldwide deepest CO2 borehole heat exchanger of this kind (heat pipe). An advantage of CO2 borehole heat exchanger is that they do not need a pump to force the circulation of the working fluid. Furthermore they are well suited for application in areas with sensible water management. The research project is to clarify if the concept "one house - one borehole heat exchanger " is technically feasible for private homes. It is coordinated by the European Institute for Energy Research, a joint venture of EDF and University of Karlsruhe. | |
