Mitsubishi, ExxonMobil team up for world’s largest low-carbon hydrogen project

In Japan, Mitsubishi Corporation and ExxonMobil signed a Project Framework Agreement to collaborate on building the world’s largest low-carbon hydrogen facility at ExxonMobil’s Baytown, Texas site, to produce hydrogen with 98% of its carbon dioxide captured.

The facility is expected to produce up to 1 billion cubic feet of hydrogen per day, advancing the companies’ commitments to reducing global emissions. This ambitious project, which is contingent on regulatory approval and supportive government policies, aims to begin operations in 2029. The facility will also produce over 1 million tons of low-carbon ammonia annually, set to be exported to Japan.

The agreement outlines Mitsubishi’s potential equity participation in the project and offtake of low-carbon ammonia, which will be used in Japan’s power generation, process heating, and other industrial activities. The ammonia will be delivered primarily to Mitsubishi’s Namikata terminal, where it will help decarbonize industries in Japan’s Shikoku and Chugoku regions.

Mitsubishi is also partnering with Idemitsu Kosan Co., Ltd. to further develop ammonia supply chains, underscoring both companies’ roles in the growing low-carbon energy market. A final investment decision is expected by 2025.
