Fortum joint venture plans carbon negative district heating in Sweden

Fortum joint venture plans carbon negative district heating in Sweden

A joint venture between Finnish company Fortum and the city of Stockholm is planning to develop what could be the world’s first carbon negative district heating network.

Stockholm Exergi is closing its last coal-fired boiler for electricity and heat production at the Värtaverket power plant in Stockholm at the end of spring 2020, two years earlier than planned.

It already replaced most of the coal-based production at the plant with biofuels in 2016 and is now exploring whether a carbon capture system could be used at the plant, which would make it carbon negative.

The captured carbon could be stored permanently in seabed rock formations, utilised in industrial processes or even used in greenhouses.

Stockholm Exergi has more than 880,000 heating customers and its district cooling is used in more than 400 hospitals, data centres and companies.

The joint venture is targeting 100% renewable fuels at its facilities by 2022.

Fortum is also testing carbon capture and storage (CCS) technology in Oslo. Both the Stockholm and Oslo projects are partnering with the Northern Lights initiative, which is studying carbon storage in the bedrock of the North Sea.
