Project development group Skanska has signed a SEK990m phase-two contract with energy provider Stockholm Exergi for the upcoming bioenergy with carbon capture and storage (BECCS) site in the Swedish capital.
The site, at Energihamnen in Värtan, is set to be one of the world’s largest facilities for capturing and permanently storing biogenic CO2.
The existing agreement between the parties for phase one is now complemented by a contract for the second phase, which includes foundation, ground, and concrete work for the BECCS building as well as a new quay.
Work on the new facility starts immediately and is planned to be completed during 2028, and follows Stockholm Exergi recently announcing final investment decision on the SEK13bn project.
The nearby Värtaverket already produces sustainable heat and electricity from residues from the forest and sawmill industries.
Now the capture and storage of biogenic CO2 is also being added. The facility will annually capture and store approximately 800,000 tonnes of CO2 from flue gases generated by the plant.
BECCS is a technology that captures biogenic CO2 before it reaches the atmosphere to then be permanently stored in bedrock.
The construction of the facility is part of the City of Stockholm’s goal to become a climate-positive area by 2030.
