Air Liquide announced that its large-scale CO2 liquefication technology, Cryocap LQ, has been chosen by Stockholm’s energy company, Stockholm Exergi, to contribute to its Bio-Energy Carbon Capture and Storage (BECCS) project.
This new technology represents a significant addition to Air Liquide’s lineup of proprietary technologies, facilitating the development of extensive Carbon Capture & Storage (CCS) networks.
The liquefaction solution enables the transportation of CO₂ across significant distances to carbon sinks where it can be permanently stored, thereby supporting the feasibility of CCS initiatives and the growth of a low-carbon economy.
As per the agreement, Air Liquide will provide the CO2 liquefaction technology and equipment for the BECCS project, which will be constructed at an existing heat and power biomass 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 nearly 8 million tonnes of biogenic CO2 over the first 10 years of the plant’s functioning.
The BECCS project is financially backed 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, said, “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.”
He added, “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.”
Air Liquide’s advanced Cryocap LQ technology, built on its expertise in cryogenics, distinguishes itself with a chemical-free, non-flammable process and a compact design.
It also facilitates the recovery and reuse of process-generated heat to support Stockholm’s district heating network. These innovations boost sustainability, safety, and energy efficiency, surpassing conventional liquefaction solutions.
