Development of unused heat potentials

Since the introduction of the EEG (Renewable Energy Sources Act) and the beginning of the energy turnaround, renewable sources are sought to replace fossil fuels for electricity and heat supply

The concept of agrothermics opened a solution direction. Developed in Brandenburg, Germany, and first implemented to supply heat to a new housing development in Wüstenrot, Baden-Württemberg, Germany, the cold heat network system has proven to be a highly efficient, robust, low-maintenance, and secure supply since operations began in 2012. Jens Kluge from the Doppelacker engineering office in Petershagen, Brandenburg, developed the idea of thermal utilization of farmland and open spaces as an infrastructure for low-temperature supply for neighborhoods, municipalities and industrial sites.

The research project "EnEff:Wärme KollWeb 4.0 Erschließung unutzter Wärmepotentiale" (EnEff:Heat KollWeb 4.0 Exploitation of Unused Heat Potentials), which is based at the Technical University of Dresden, is divided into two main areas: technology development, which the cooperation partner Doppelacker GmbH is working on. And the development of a machine system for collector installation, which was developed in terms of content by the Institute for Natural Materials Technology around Prof. Herlitzius and administratively by the GWT-TUD. The overall objective of the research project is the technically and economically efficient extraction of geothermal energy for grid-connected low-temperature supply. The developed machine system simplifies the installation of collector registers with high area throughput. Minimum area development from sports field size, 5,000 m2 (0.5 ha). Agricultural land and agrothermics allow dual use.
