Local features
Rhine-water heat pump for district heating
Duisburg is adding a 60 MW large heat pump to the district heating network, using Rhine water as a heat source. Stadtwerke is investing around 200 million EUR in modernising Energiepark Wanheim. From commissioning in early 2029, the plant is intended to cover the heat demand of around 23.500 households at around 6.000 Vollbenutzungsstunden per year. Owners in the priority area benefit indirectly from increasingly green district heating.
Industrial waste heat potential
As a steel and industrial city, Duisburg has high potential for using waste heat in neighbourhood heating networks.
