Electrolyzers for sustainable hydrogen production
On November 8, 2023, the Air Liquide Siemens Energy joint venture launched production at its state-of-the-art gigafactory in Berlin. This highly automated 2,000 m² plant utilizes cutting-edge robotics to produce proton exchange membrane (PEM) electrolysis stacks. With an initial manufacturing capacity of 1 GW per year, the facility aims to ramp-up to at least 3 GW by 2025. The strategic partnership and joint venture supports several of Air Liquide’s hydrogen projects, including the 20 MW Trailblazer project in Oberhausen, Germany, the 200 MW Normand’Hy project in Port-Jérôme, France, and two additional 200 MW projects in the Netherlands.
Autothermal reforming based low-carbon hydrogen and ammonia technology
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™, CO2 cold capture system
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.
The world's largest PEM electrolyzer
Air 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 production
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.
SMR-X™, a zero steam hydrogen plant solution
SMR-X™ enables zero steam hydrogen production, with 4% natural gas fuel savings and 4% reduced CO2 emissions compared to conventional installations.
Highly energy efficient Nitrogen Generator for the electronics market
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.
Development of an ammonia cracking industrial scale pilot plant
Advancing hydrogen as a pivotal energy source, Air Liquide is constructing an industrial-scale ammonia cracking pilot plant in the port of Antwerp, Belgium. This innovative facility, central to our ammonia cracking technology development, will convert ammonia into hydrogen with an optimized carbon footprint.
