RegEWS - Feasibility study on reducing the space requirements of large geothermal probe fields for thermal networks

The core of the concept is the combination of a large heat pump, geothermal probe field, and waste heat utilization, supplemented by air heat utilization and renewable peak load coverage. Regeneration with waste heat from waste incineration plants up to 70 °C significantly increases the usable storage capacity of the geothermal probe storage compared to conventional regeneration, which means that the storage can be significantly smaller and therefore more cost-effective.

RegEWS thus opens up new possibilities for compact, fully renewable heating networks – especially in densely built-up areas with limited space and a lack of alternatives such as groundwater or biomass. Due to the promising results, the concept is being pursued further in a preliminary project.
