CO₂-neutrality in new district in Aarhus Ø

District heating and cooling Solutions

Aarhus Municipality aims to be CO2-neutral by 2030, which means that the production of electricity and heat needs to be converted so it no longer uses fossil fuels like oil, coal and natural gas.

Aarhus Ø is an example of innovative thinking in district heat supplies, to address both increased pressure on the district heating network and a growing desire among local residents for sustainable urban development.

The project contributes to this green vision by testing the potential of seawater heat pumps. It involves a new heat supply plant in the Port of Aarhus to serve a new district called Aarhus Ø (East), comprising seawater heat pumps and heat exchangers.

It means that Aarhus Ø will be supplied with district heat obtained from seawater in Aarhus Bay, where an electric heat pump will extract heat from the seawater. The building will also contain a central vacuum waste disposal system which will collect waste from the whole of Aarhus Ø.
