The world’s largest heat pumps will be used for climate-friendly district heating generation in Aalborg, Denmark, in the successor to the Esbjerg heat pump project.
MAN ES is currently installing a heat pump system with a capacity of 60 MW in the Danish seaport town of Esbjerg. It will be supplied with electricity from offshore wind farms and use the Wadden Sea as an energy source. The new co-generation plant will replace the town’s existing coal-fired power plant and supply around 25,000 households with approximately 280,000 MWh of climate-friendly heat a year.
MAN supports Aalborg on its way to net zero
The location of Aalborg Forsyning’s district heating plant in Norbis Park on the north bank of the Limfjord makes it possible to use seawater as a heat source. Heat pump units will use renewable electricity to raise the temperature of the seawater (from 1-15 °C) to a maximum of 98 °C, the temperature required by the district heating network. Compared with the existing coal-fired power plant, which is to be decommissioned in 2028, the heat pump solution will reduce carbon emissions by 160,000 metric tons a year. At the heart of the Aalborg system are three oil-free, hermetically sealed HOFIM® motor compressor units, all built and tested in Zurich. CO2 will be used in a closed circuit as a natural coolant. Construction work on the project is scheduled to start in August 2024. It is anticipated that the heat pump system will be handed over to Aalborg Forsyning in 2027 following testing and commissioning.
