Cryogenic technologies

Capturing, cooling and storing to save energy

Used initially in the space industry, Air Liquide’s Turbo-Brayton technology has found a promising market in the maritime transport of liquefied natural gas (LNG). Onboard LNG tankers, it prevents boil-off, contributing to the reduction of economic loss and CO2 emissions. This technology is also used to liquefy biomethane that can then be easily transported to its point of use, such as bio-NGV (natural gas for vehicles) stations or industrial customers. This promising fuel alternative is a sustainable source of energy, of which Air Liquide will produce 1.8 TWh annually on a global scale by the end of 2022.
