Air Liquide has achieved a significant milestone in 2024 with its Turbo-Brayton cryogenic equipment, securing close to 70 orders throughout the year. This innovative solution has been widely adopted by the maritime transport industry, offering an effective response to the challenges of onboard boil-off gas reliquefaction. The continued commercial and industrial success of this technology underscores Air Liquide’s ability to develop cutting-edge, efficient solutions that meet critical market demands while advancing full industrialisation.
From Space to Maritime Applications
Initially developed for the space industry, the Turbo-Brayton technology was originally used to cryogenically preserve biological samples on the International Space Station (ISS). The system was later adapted and scaled up for the maritime transport industry, where its key features—plug-and-play installation, preventive maintenance-free operation, low electrical consumption, and high reliability—have positioned it as the preferred solution. The technology enables compliance with regulations on boil-off gases while also meeting the industry’s requirements for safety, environmental protection, and operational efficiency.
Enhancing LNG Transport Efficiency
During transportation, Liquid Natural Gas naturally reheats, causing partial evaporation. Air Liquide’s Turbo-Brayton subcooler cryogenic equipment reliquefies the evaporated gas, ensuring that it remains in liquid form within storage tanks. The system is specifically designed for LNG carriers and bunker vessels and can be installed on both newly built ships and retrofitted existing vessels.
Strengthening Market Position
Over the past six years, orders for this solution have exceeded one billion euros, with more than 250 units sold. This sustained growth reinforces Air Liquide’s position as a reliable and trusted partner for the maritime sector, further solidifying its leadership in cryogenic gas management technologies.
