Project description:

By means of a numerical model for simulating the complex geothermal storage system, the components building and storage unit are to interact with each other. The research cooperation is intended to gain initial virtual operating experience in terms of the design of the building services and sustainable storage management.

Old FiF project - current topic

This FiF project has created an important scientific basis for evaluating the systems through the numerical modelling of the integration of a medium-depth borehole heat exchanger into an existing building and local heating network. The results were crucial for the approval of the other research projects SKEWs (seasonal crystalline borehole heat exchanger, BMWK) and Push-It (Piloting Underground Storage of Heat In geoThermal reservoirs).

Within the SKEWs project, a medium-depth research geothermal probe storage facility consisting of three 750 metre-deep geothermal probes was installed and tested on the Lichtwiese campus. The follow-up project Push-It includes the integration of the borehole heat exchanger into the local heating network of TU Lichtwiese.

The current co-operation partners of the project and corresponding publications are listed on the linked pages.
