As part of a new milestone in the Stockholm Exergy Bioenergy Carbon Capture and Storage (BECCS) project, the company has selected Air Liquide’s groundbreaking CO2 liquefaction technology.
This cutting-edge technology, named Cryocap™ LQ, is a significant addition to Air Liquide’s proprietary technology portfolio and will facilitate the development of an extended Carbon Capture and Storage (CCS) value chain. CO₂ liquefaction solutions enable liquid CO2 to be transported long distances to permanent carbon storage sites, making CCS projects more feasible.
Philippe Merino, Group Vice President, Engineering and Construction at Air Liquide, said: “Cryocap™ LQ CO₂ liquefaction technology is a new addition to Air Liquide’s low-carbon technology portfolio, particularly suited for large-scale CCS projects. In line with Air Liquide’s ADVANCE strategic plan, Air Liquide aims to actively contribute to the realization of a low-carbon society.”
According to the contract, Air Liquide will supply its CO2 liquefaction technology and equipment to the BECCS project at Stockholm’s existing biomass heat and power combined heat and power plant (bio-cogeneration). The Cryocap™ LQ CO2 liquefaction unit to be supplied by Air Liquide will be one of the largest in the world, with a processing capacity of 3,500 tonnes per day.
“If you can manage your waste, you can manage your CO2,” says Claude Letourneau, CEO of Svante.
The BECCS facility aims to liquefy and store around eight million tonnes of biogenic CO2 over the first 10 years of operation. The project is supported by the European Innovation Fund, one of the world’s largest programs supporting innovative low-carbon technologies.
Air Liquide’s Cryocap™ LQ technology demonstrates the company’s expertise in cryogenics, featuring a chemical-free, non-flammable process and a compact design. The advanced system also allows heat generated during the process to be captured and reused to feed Stockholm’s district heating network. These features improve sustainability, safety and provide greater energy efficiency compared to traditional liquefaction methods.
