Stockholm Exergi has announced plans to build one of the world’s largest facilities for capturing and permanently storing biogenic carbon dioxide. The SEK 13 billion (€1.2 billion) investment marks a significant milestone in advancing permanent carbon removals, supporting Sweden and the EU’s long-term climate goals.
Construction will commence immediately, with the facility expected to be operational by 2028. The project is made possible through a combination of public funding and private-sector purchases of negative emission certificates from companies committed to ambitious climate targets.
The new facility will be located in Stockholm’s energy port near Värtaverket and will capture and store 800,000 tonnes of CO₂ annually—equivalent to offsetting the emissions from Stockholm’s entire road traffic over the same period.
Stockholm Exergi has been operating a test facility since 2019, utilizing CO₂ capture technology that has been in use since the 1970s. The captured CO₂ will be permanently stored in bedrock beneath the seabed, where it mineralizes over time.
“This is a historic moment for Stockholm Exergi and for the green transition. We have worked purposefully for many years to make bio-CCS a reality, and today’s decision means that we are moving from plans to action. With this, we assume global leadership in the industry for permanent removals,” said Anders Egelrud, CEO of Stockholm Exergi.
