Danish multi-utility company, Aalborg Forsyning, has placed a follow-up order with MAN Energy Solutions for an additional heat pump unit, increasing the overall heating capacity to 177 MW with four units. This follows the initial order submitted in 2023, significantly expanding the scope of the project. Each heat pump has a capacity of around 44 MW, making them the largest heat pump units ever to be installed in district heating plant worldwide. Collectively, the plant will supply up to 700,000 MWh of heat annually, or equivalent to one-third of Aalborg’s heat production.
Situated on the northern bank of the Limfjord strait, the district heating plant will use seawater as a heat source. The heat pumps will utilize electricity from Aalborg Forsyning’s renewable sources to elevate the water temperature from 1-15° Celsius up to 98°, which is the temperature used in the district heating network. This project will reduce CO2 emissions by up to 210,000 tons annually compared to the city’s coal-fired power plant, scheduled for closure in 2028.
