As part of the research project at the Lichtwiese campus of the Technical University of Darmstadt four 750 m deep borehole heat exchangers will be drilled within a distance of 5 m to build the world's first medium-deep borehole energy storage. The storage system will undergo a 1.5-year test cycle to simulate a seasonal heat supply via mobile heaters and mobile cooling devices. The project’s goal is to demonstrate the buildability and operability of such systems and to verify the operation and design routines. An enlargement of the plant for an economic operation is already in the planning.
A continuous thermal and hydrochemical monitoring will be carried out via three nearby wells during the building and operating phase to quantify the systems impact on the near surface aquifer. The operating and monitoring results will be used to improve and validate existing numeric simulation tools.
