Air Liquide's innovative large scale CO₂ liquefaction technology, Cryocap LQ, has been selected by Stockholm Exergi, Stockholm’s energy company, to contribute to its Bio-Energy Carbon Capture & Storage (BECCS) project.

This new technology is an important additional brick in Air Liquide’s portfolio of proprietary technologies that paves the way to developing large-scale Carbon Capture & Storage (CCS) value chains. The CO₂ liquefaction solution allows to transport CO₂ over long distances to carbon sinks for permanent storage, contributing to the viability of CCS projects and emergence of a low-carbon industry.

Under the framework of the agreement, Air Liquide will provide the CO₂ liquefaction technology and equipment for the BECCS project to be built at an existing heat and power biomass (bio-cogeneration) plant in Stockholm.

The Cryocap LQ CO2 liquefaction unit supplied by Air Liquide will be one of the largest in the world with a capacity of 3,500 tonnes per day. After liquefaction, the CO₂ will be transported for permanent storage. The BECCS facility aims to liquefy and store around eight million tonnes of biogenic CO₂ over the first 10 years of operation. The BECCS project is supported by the European Innovation Fund, one of the world’s largest programs for promoting innovative low-carbon technologies.

Philippe Merino, Group Vice President supervising Engineering & Construction at Air Liquide stated: We are pleased that Air Liquide’s technology has been selected for the Stockholm Exergi innovative CCS project. Cryocap™ LQ CO₂ liquefaction technology is a new addition to Air Liquide’s portfolio of low-carbon technologies, and is particularly suited to large scale CCS projects. In line with Air Liquide’s strategic plan ADVANCE, Air Liquide’s ambition is to contribute actively to the emergence of a low-carbon society. Drawing on our innovative capabilities and expertise we are able to help our customers achieve their decarbonization goals and forge a sustainable future.
