The city of Hamburg is to boast a fossil fuel free sewage treatment system from 2025. That is thanks to a heat pump project coordinated by Hamburg’s water and energy companies.
The new system, which will have four heat pumps provided by Johnson Controls, will avoid around 66,000 tonnes of CO2 per year.
The 15 MW heat pumps will extract heat from the treated wastewater that leaves the sewage treatment plant every day and feed it into the central district heating network. This will help heat around 39,000 homes with clean heat.
Christian Heine, spokesman for the management of Hamburger Energiewerke says:
“The Hamburg wastewater heat project is an example of how the heat transition can succeed if we consistently use local energy sources and the latest technologies.”
