Update from Darmstadt’s BTES project

At the Lichtwiese Campus of Technische Universität Darmstadt, the Borehole Thermal Energy Storage (BTES) installation is now entering its final phase of completion! During this phase, our team in Darmstadt will be install coaxial composite inner pipes, which are constructed using a powerful combination of steel and polymer materials. Coaxial pipes are designed with one pipe inserted inside another, like a telescope, providing efficient heat transfer and storage. This solution enhances the system’s efficiency and durability.

Back in November 2022, a major milestone was achieved with the successful construction of three boreholes and three monitor wells. Once the current completion phase is finished in a few months, we will be start up with the 1.5-year testing phase of the system.

Stay tuned for more updates as we embark on this exciting journey towards decarbonising heating!
