ADNOC will acquire a 35% equity stake in Exxon Mobil Corporation’s proposed low-carbon hydrogen and ammonia production facility in Baytown, Texas.

The agreement represents a significant investment in the United States’ energy production and the global energy transition. It will help reduce greenhouse gas emissions across hard-to-decarbonize sectors, including industry, energy and transportation, meet rising demand for lower-carbon fuels, and accelerate a net-zero future.

Contingent on supportive government policy and necessary regulatory permits, the facility is expected to be the world’s largest of its kind upon startup, capable of producing up to 1 billion cubic feet (bcf) daily of low-carbon hydrogen, which is virtually carbon-free with approximately 98% of CO₂ removed and more than 1 million tons of low-carbon ammonia per year. A final investment decision (FID) is expected in 2025 with anticipated startup in 2029.

The facility will leverage advanced carbon capture and The project’s construction will also bring substantial economic benefits to Baytown, the Houston area and Texas.

Following FID for the project, ADNOC intends to support ongoing community initiatives in the Baytown area, in line with the company’s commitment to sustainability and education in the locations where it operates.
