Everllence has been chosen by EPC contractor Saipem to provide core compressor and expander technology for Stockholm Exergi’s Bioenergy with Carbon Capture and Storage (BECCS) project — one of the world’s largest bioenergy-based carbon removal initiatives.

The facility, located at the Värtaverket biomass power plant in Stockholm, will capture and permanently store biogenic carbon dioxide released during the combustion of sustainably sourced forest residues. Once operational, it is expected to remove up to 800,000 tons of CO₂ annually — more than the yearly emissions from all road traffic in Sweden’s capital.

Technology at the core

Everllence will supply its electrically driven MAX1 compressor train, including the AG110 axial compressor and EN080 axial expander, to manage the plant’s high-volume flue gas. The technology is designed for high-efficiency performance in continuous large-scale operation, ensuring reliability while maximizing energy recovery.

“This project marks a major step toward industrial-scale carbon removals,” said Dr. Uwe Lauber, CEO of Everllence. “By enabling the permanent storage of biogenic CO₂, the facility supports Sweden’s ambition to become climate-positive by 2030 — and serves as a scalable model for urban carbon removal worldwide. We are proud to contribute to this pioneering initiative with our high-efficiency axial compressor and expander train.”

The captured CO₂ will be transported for permanent storage beneath the North Sea through the Northern Lights infrastructure.

Government backing and corporate support

The BECCS project is supported by the Swedish government and EU funding and has already secured long-term carbon removal agreements with global corporations, including Microsoft. Stockholm Exergi’s biomass power plant currently provides heat and electricity to more than 800,000 residents in the city.

“Stockholm is the first BECCS facility to implement this configuration — and it sets a new benchmark for efficiency and scalability in the carbon capture sector,” said Uwe Emmerich, head of sales petrochemicals and energy storage at Everllence. “Our proven axial turbomachinery is ideally suited for high-volume flue gas applications like this one, ensuring stable operation under demanding conditions.”

Scaling carbon removals

The project is viewed as a landmark in advancing bioenergy-based carbon capture. By combining biomass combustion with permanent CO₂ storage, it not only delivers negative emissions but also demonstrates a replicable pathway for other urban utilities worldwide.

For Everllence, formerly known as MAN Energy Solutions, the contract represents a continuation of its strategy to position advanced turbomachinery at the center of low-carbon energy infrastructure.
