Rhine Supplies Thermal Energy via New Large-Scale Heat Pump

18 metres long, around five metres high, and highly efficient: Mannheim-based energy company MVV is building a river water source heat pump along the bank of the Rhine by the GKM power station in Mannheim. The heat pump extracts thermal energy from the river and uses it to produce heating water. Around 90 stakeholders from industry, politics, and science were present to witness the official start of construction.

New: Large-Scale Heat Pumps in Germany’s District Heating Networks


A large proportion of Germany’s CO2 emissions can be attributed to the supply of heat. Large-scale heat pumps powered by greenhouse gas-free electricity could help the country to reduce its CO2 emissions. In the living lab for the energy transition focused on the installation, operation, monitoring, and system integration of large-scale heat pumps (LHPs) in district heating networks, these systems will now be connected to district heating networks at various types of location.
