Baytown Low Carbon Hydrogen Project

The Baytown Low-Carbon Hydrogen Project is a large-scale blue hydrogen and carbon capture development at ExxonMobil’s Baytown complex near Houston, Texas. The project is designed to integrate hydrogen production with large post-combustion and process CO₂ capture systems capable of capturing up to approximately 7 million metric tons of CO₂ per year, positioning it among the largest planned industrial CCS deployments globally. Captured CO₂ will be transported through ExxonMobil’s Denbury CO₂ pipeline network and injected into ExxonMobil-operated Class VI geological storage projects. ExxonMobil has advanced the project with multiple commercial and technology partners. Air Liquide is providing hydrogen and industrial gas integration infrastructure. Mitsubishi Corporation has signed cooperation agreements supporting project development and commercial structuring. Trammo has executed an agreement to offtake low-carbon ammonia produced from the facility, and ADNOC has partnered with ExxonMobil to jointly advance low-carbon hydrogen and ammonia supply chains. Front-end engineering and design activities were awarded to advance capture system integration, compression, dehydration, and CO₂ export infrastructure. ExxonMobil has since paused development of the Baytown low-carbon hydrogen and CCS project, delaying final investment and construction timelines.
