Engineering & Technologies

The Air Liquide and Siemens Energy joint venture state-of-the-art gigafactory in Berlin, is a highly automated 2,000 m² plant utilizing cutting-edge robotics to produce proton exchange membrane (PEM) electrolysis stacks. The joint venture has already supported Air Liquide’s 20 MW Trailblazer project in Oberhausen, Germany and now, several of Air Liquide’s hydrogen projects, including the 200 MW Normand’Hy project in France, 200MW Elygator Project and 250MW Air Liquide / TotalEnergies Joint Venture project in the Netherlands.

Drawing on seven decades of expertise, Air Liquide's proprietary Autothermal Reforming Technology (ATR), combined with carbon capture, facilitates industrial-scale low-carbon hydrogen and ammonia production with a carbon capture rate of up to 99%. In 2023, this advanced technology was chosen for Japan’s inaugural ATR demonstration project by INPEX, aimed at efficiently producing large-scale low-carbon hydrogen and ammonia.

Cryocap™ technology captures CO₂ released during hydrogen production through a cryogenic process. The first industrial deployment occurred at the largest steam methane reforming hydrogen production unit operated by Air Liquide in Port-Jérôme, France, showcasing the potential of Cryocap™ to significantly reduce CO₂ emissions.

Air Liquide has engineered the largest single train air separation unit ever constructed. With a capacity of 5,800 tons of oxygen per day at mean sea level, this unit supplies industrial gases to Sasol’s Secunda site in South Africa. By 2030, Air Liquide plans to reduce the plant's CO₂ emissions by 30-40% through the integration of 600 MW of renewable energy.

The Group has 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.

The electronics market is rapidly evolving, driven by the key trend in digital transformation and the subsequent market demand and global growth. To support this growth, Air Liquide is scaling up investments in major semiconductor Fabs, enhancing customer’s presence in key markets such as smart mobile devices, automotive, IoT and data centers. Air Liquide’s Nitrogen Generator for the electronics market enable the production of large quantities of ultra-pure nitrogen and other molecules with optimized best-in class efficiency.

We design and manufacture biomethane production units that purify biogas from agricultural, household, or industrial waste. Biomethane has many applications, notably clean mobility (as natural gas for trucks, buses, ferries etc.), electrical networks, and heating. We master its entire value chain, from production to distribution.

This innovative solution is particularly acclaimed by the maritime transport industry as it effectively addresses the challenges of onboard boil-off gas reliquefaction. This continued commercial and industrial success illustrates the capacity of the Group to develop innovative and efficient technological solutions toward full industrialization to best meet a critical market need. In 2024, Air Liquide reached a new milestone with its Turbo-Brayton cryogenic equipment, with nearly 70 units ordered during the year.
