Demo site for Borehole Thermal Energy Storage (BTES).
In Darmstadt, we will integrate a medium-depth Borehole Thermal Energy Storage (BTES) into the surface district heating grid at the Lichtwiese Campus of TU Darmstadt. The BTES consists of three 750-meter-deep geothermal borehole heat exchangers and is the world’s first demonstration of this heat storage technology. We aim to do the following:
We aim to integrate the three medium-deep borehole heat exchangers into the district heating grid of the campus. This district heating grid is independent of the city grid and is decomposed into sub-networks.
Several scenarios are investigated in cooperation with construction management services of TU Darmstadt to implement the most useful integration.
A first scenario investigated would be to connect the three boreholes with two new buildings and their district heating grids constructed close to the storage site. The heat storage system can supply heat during peak heat demand of the two buildings.
Another scenario considered is to investigate the possibility of extending the BTES field and connect it to a larger sub-grid, which would then contain the two new buildings plus the Engineering department building.
