Summary
The district heating in Copenhagen is already 85 percent CO2-neutral, but sustainable heating will receive an additional boost over the next ten years. HOFOR plans to establish collective electric heat pumps that use green power from wind turbines and harness the temperature of surplus heat, seawater, and wastewater, for example, to create the district heating that Copenhagen residents receive in their radiators.
When heat is electrified in this way, it provides greater flexibility in the entire energy system. We can use the green power when it’s available and turn it off again when it’s too expensive, says Gorm K. Elikofer, Director of Energy at HOFOR.
This comes because HOFOR’s combined heat and power plant generated the city’s heat by burning coal just a few years ago. Still, today, the utility company exclusively uses documented sustainable biomass as fuel at Amagerværket.
