Together with MVV we have built a large-scale heat pump plant in Mannheim. It uses river water as a heat source, helping to reduce the use of coal at the GKM plant. The new heat pump is the first step towards the goal of green district heating. MVV and the City of Mannheim is targeting to become CO2 neutral in the district heating production by 2030.
At the Mannheim site, the heat pump uses 7 MWe of electrical power from renewable sources to produce 20 MWt of thermal energy which is used to reheat the district heating return flow up to 99 °C. From 2023 onwards, the facility is expected to supply heating for 3,500 households and save some 10,000 tonnes of carbon emissions per year.
