ExxonMobil and Air Liquide announced an agreement to support the production of low-carbon H₂ and low-carbon ammonia at ExxonMobil’s Baytown, Texas facility. The agreement will enable transportation of low-carbon H₂ through Air Liquide’s existing pipeline network. Additionally, Air Liquide will build and operate four large modular air separation units (LMAs) to supply 9,000 metric t of oxygen and up to 6,500 metric t of nitrogen daily to the facility. The LMAs will primarily use low-carbon electricity to reduce the project’s carbon footprint.

“Momentum continues to build for the world’s largest low-carbon H₂ project and the emerging H₂ market,” said Dan Ammann, President of ExxonMobil Low Carbon Solutions. “This partnership with Air Liquide further strengthens our Baytown project by enabling H₂ distribution through existing networks and securing key feedstocks.”

ExxonMobil's planned H₂ production facility will be the world’s largest. It is expected to produce 1 billion cubic feet of low-carbon H₂ daily, and more than 1 MMtpy of ammonia while capturing more than 98% of the associated CO₂ emissions.

Partnering with Air Liquide, ExxonMobil aims to enable the growth of a low-carbon H₂ market along the U.S. Gulf Coast to help industrial customers decarbonize their operations.
