July 18, 2024 [Storage Terminals Magazine]- Air Liquide’s innovative large-scale CO₂ liquefaction technology, Cryocap LQ, has been chosen by Stockholm Exergi, Stockholm’s energy company, to support its Bio-Energy Carbon Capture & Storage project. This cutting-edge technology is a significant addition to Air Liquide’s portfolio, advancing the development of large-scale carbon capture & storage value chains. The CO₂ liquefaction solution enables the transportation of CO₂ over long distances to carbon sinks for permanent storage, thereby enhancing the viability of CCS projects and the emergence of a low-carbon industry.
Under the agreement, Air Liquide will provide the CO₂ liquefaction technology and equipment for the BECCS project, which will be installed 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. Once liquefied, the CO₂ will be transported for permanent storage. The BECCS facility aims to liquefy and store around eight million tonnes of biogenic CO₂ over its first ten years of operation. The BECCS project receives support from the European Innovation Fund, one of the world’s largest programmes for promoting innovative low-carbon technologies.
Air Liquide’s Cryocap LQ technology, which leverages the company’s expertise in cryogenics, is distinguished by its chemical-free, non-flammable process and compact design. Additionally, this advanced setup will enable the recovery and reuse of heat generated from the process to supply Stockholm’s district heating network. These features contribute to enhanced sustainability, safety, and best-in-class energy efficiency compared to traditional liquefaction solutions.
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, our 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 decarbonisation goals and forge a sustainable future.”
The selection of Cryocap LQ technology for the BECCS project marks a significant step towards the realisation of a sustainable and low-carbon future, reinforcing Air Liquide’s commitment to innovation and environmental stewardship.
