Air Liquide will build, own, and operate four large modular air separation units (ASUs) as part of an $850m investment that will double its oxygen production capacity in Texas to support ExxonMobil’s proposed low-carbon hydrogen project in Baytown.
The four ASUs will primarily supply ExxonMobil with low-carbon oxygen and nitrogen. Specifically, it will generate a “record volume” of 9,000 metric tonnes of oxygen daily and 6,500 metric tonnes per day of nitrogen to support the production of low-carbon hydrogen and ammonia.
Additionally, the plants will also supply large volumes of argon and rare gases, such as krypton and xenon, for other US-based customers.
In conjunction with the plant announcement, the duo has also agreed that hydrogen produced at the Baytown facility will be transported through Air Liquide’s existing pipeline network along the US Gulf Coast in Texas and Louisiana.
