The technology, developed by Air Liquide and based on the Turbo-Brayton principle, reliquefies LNG boil-off on vessels transporting that product, thereby significantly reducing greenhouse gas emissions during transportation. Combined, the approximately 50 Turbo-Brayton cryogenic units sold have the potential to avoid more than 240 000 tpy of CO2 equivalent emissions. This equipment is specially designed for LNG carriers, both on newly built ships and for retrofitting existing vessels.
According to the statement, this technology was first used in the space industry to cryogenically preserve biological samples on the International Space Station (ISS), before being adapted for the maritime transport industry. It can also be applied to biomethane. For example, it is used to liquefy biomethane generated through the anaerobic digestion of household and agricultural waste. In liquid form, the biomethane can be transported easily to its point of use as a fuel in natural gas vehicle (NGV) stations or ferry terminals. Air Liquide has reportedly sold two such units in the Nordics.
Emilie Mouren-Renouard, Member of Air Liquide’s Executive Committee in charge of Innovation, Digital & IT, Intellectual Property and the Global Markets & Technologies WBU, said: “This commercial success illustrates the group’s capacity to support its customers by developing efficient solutions that help them lower the environmental impact of their activities. Air Liquide has long been innovating for a low-carbon society. Our climate objectives are now the most ambitious in our sector and these new technologies, which are acclaimed by our customers, contribute to reducing CO2 emissions.”
