Our commitment to sustainability
Air Liquide Engineering & Construction is working actively to help achieve the Group's environmental, societal and governance (ESG) objectives. Drawing on our know-how and innovative technology solutions, Air Liquide Engineering & Construction is working with its customers to reduce their carbon emissions, supporting them in their energy transition and supporting the Group and customers to play their part in creating a low-carbon society.
At the heart of innovation
Air Liquide Engineering & Construction innovates across all areas of its activities, nurturing the inclusion and diversity, growth and entrepreneurial spirit of employees and supporting the technical creativity of its teams to develop unique solutions that make a real difference to our customers.
At our Cryogenic Technology Center in Vitry-sur-Seine (France), innovations related to cryogenic technology topics are developed, tested and demonstrated in an accelerated innovation cycle, thus being ready for early industrialization.
Cryocap™, CO2 cold capture systemCryocap™ enables the capture of CO2 released during hydrogen production via a cryogenic process. The first industrial deployment of this technology was made in Port-Jérôme, France, at the largest steam methane reforming hydrogen production unit operated by Air Liquide.
The world's largest PEM electrolyzerAir Liquide Engineering & Construction contributed to the construction of the world's largest PEM (Proton Exchange Membrane) electrolyzer. Supplied with renewable energy, this unit is now producing up to 8.2 tonnes per day of low-carbon hydrogen in Bécancour, Québec. This way, Air Liquide confirms its commitment to the production of low-carbon hydrogen on an industrial scale and its ability to effectively deploy the related technological solutions.
The world’s largest plants for industrial gas productionWe have designed and assembled the largest single train air separation unit ever built. With a total capacity of 5,800 tons of oxygen per day (at mean sea level), the unit will supply industrial gases to the Secunda site for Sasol in South Africa. By 2030, Air Liquide will reduce the CO2 emissions of the plant by 30-40% through the sourcing of 600 MW of renewable energy.
We have also designed and built units for the global-scale hydrogen production site in Yanbu Industrial City in Saudi Arabia with a total capacity of 340,000 Nm3 per hour.
SMR-X™, a zero steam hydrogen plant solutionSMR-X™ enables zero steam hydrogen production, with 4% natural gas fuel savings and 4% reduced CO2 emissions compared to conventional installations.
