Air Liquide invests 350M USD in Louisiana to support low-carbon steel production and strengthen industrial infrastructure growth.
Air Liquide has announced a major investment of more than 350 million USD to strengthen its operations in Louisiana while supporting the growing demand for low-carbon steel production in the United States. The company has signed a long-term agreement with HYUNDAI-POSCO Louisiana LLC (HPLS) to supply essential industrial gases such as oxygen, nitrogen, and argon for HPLS’s new environmentally advanced steel manufacturing facility in Louisiana. This project represents a significant step toward localized and sustainable production of critical industrial materials for the U.S. market.
The new HPLS steel plant is designed to focus on low-carbon emissions steel production, helping reduce the environmental impact traditionally associated with steel manufacturing. Through this collaboration, Air Liquide will play an important role in supporting cleaner industrial practices by providing reliable and efficient gas supply systems required for the facility’s operations. The agreement highlights Air Liquide’s capability to support customers not only in local projects but also in their broader international expansion plans.
To fulfill this partnership, Air Liquide will establish an additional Air Separation Unit (ASU) in St. James Parish, located at the existing Koch Methanol facility. This new unit will increase the company’s production capacity and ensure a stable supply of industrial gases for HPLS. In addition to the ASU, Air Liquide will also expand its pipeline and network infrastructure along the Mississippi River corridor. This development will further strengthen the company’s industrial presence in Louisiana and reinforce its leadership position in one of the most important industrial regions in the country.
This agreement is especially important because it marks Air Liquide’s first major partnership with HPLS in the United States. It also reflects the growing trend of reshoring industrial production back to America, where companies are investing in domestic manufacturing to improve supply chain security and reduce dependency on overseas production. By supporting HPLS’s low-carbon steel facility, Air Liquide is contributing to the return of advanced industrial manufacturing to the U.S. while helping industries meet sustainability goals.
The project will also create additional benefits for Koch Methanol’s St. James facility. Air Liquide’s investment and infrastructure expansion will support increased methanol production under Koch Methanol’s ongoing Optimization Project. This means the initiative not only benefits steel manufacturing but also strengthens the broader industrial ecosystem in the region.
Air Liquide’s supply model is specifically designed for high efficiency, scalability, and easy integration with advanced sustainable technologies. Its strong pipeline network ensures flexibility and operational reliability, which are critical for next-generation manufacturing plants like the HPLS facility. The supply of gases for the steel plant is expected to begin in 2028, marking a long-term commitment to industrial decarbonization and regional growth.
Matthieu Giard, a member of Air Liquide’s Group Executive Committee responsible for operations in the Americas, emphasized that this partnership reflects the company’s dedication to supporting industrial decarbonization across the United States. He stated that by using Air Liquide’s extensive Mississippi River infrastructure and advanced technologies, the company can deliver both reliability and flexibility needed for HPLS’s innovative green steel production.
Louisiana Governor Jeff Landry also praised the investment, stating that Air Liquide’s continued expansion proves Louisiana is a strong destination for industrial growth and global competitiveness. He highlighted the company’s long-standing presence in the state and expressed confidence that such investments create jobs, encourage faster business growth, and provide meaningful economic opportunities for Louisiana residents.
