Global industrial gases and engineering company Linde has signed a new long-term agreement to supply oxygen and nitrogen to Blue Point’s low-carbon ammonia plant in Ascension Parish, Louisiana.

Linde will invest more than $400 million build, own, and operate a world-scale air separation unit (ASU) to supply Blue Point, which is expected to be one of the largest low-carbon ammonia projects in the world. The on-site plant, which is expected to start up in 2029, will be Linde’s third state-of-the-art ASU supplying a major autothermal reforming plant. It’s also the latest in a series of investments by Linde in the U.S. Gulf Coast.

Blue Point is a joint venture between CF Industries, JERA and Mitsui & Co.

In a press statement, Linde Executive Vice President North America Sean Durbin said the company’s newest investment in the U.S. Gulf Coast industrial gases corridor would increase network density in a region “where demand for industrial gases is continuously growing.”
