Air Liquide to Invest $350M in Louisiana

Air Liquide has entered into a long-term agreement to supply oxygen, nitrogen and argon to Hyundai-POSCO Louisiana LLC (HPLS) for its new low-carbon emissions steel facility in Louisiana. This investment supports the development of localized, low-carbon production of critical materials for the U.S. market, and contributes to reshoring efforts.

Air Liquide will invest over $350 million USD to expand its production with an additional air separation unit (ASU) in St. James Parish at the exhisting Koch methanol facility, as well as network infrastructures along the Mississippi River. 

This strategic partnership marks Air Liquide’s first major agreement with HPLS in the U.S., supporting its global expansion. By building and integrating high-efficiency gas supply solutions, Air Liquide ensures the industrial gases volumes essential for HPLS’s low-carbon steel production goals are met. This project will also support additional methanol production at the Koch Methanol St. James facility under its Optimization Project, which is already underway.

Air Liquide’s extensive pipeline infrastructure ensures the operational flexibility required for this next-generation facility, with supply expected to commence in 2028.
