ExxonMobil announced the next step in the development of the world’s largest low-carbon hydrogen production facility with a contract award for front-end engineering and design (FEED) to Technip Energies. A final investment decision for the project is expected by 2024, subject to stakeholder support, regulatory permitting, and market conditions.
- Project targets 1 billion cubic feet of low-carbon hydrogen per day, while capturing more than 98% of associated CO2 emissions
- Offtake agreements under discussion with third party customers
- Up to 30% reduction in Scope 1 and 2 emissions at Baytown integrated complex
ExxonMobil’s Baytown low-carbon hydrogen, ammonia and carbon capture facility is expected to produce one billion cubic feet of low-carbon hydrogen per day, making it the largest low-carbon hydrogen project in the world at planned startup in 2027-2028.
More than 98% of the associated CO2 produced by the facility, or around 7 million metric tons per year, is expected to be captured and permanently stored. The carbon capture and storage network being developed for the project will be made available for use by third-party CO2 emitters in the area in support of their decarbonization efforts.
“This project allows us to offer significant volumes of low-carbon hydrogen and ammonia to third party customers in support of their decarbonization efforts,” said Dan Ammann, president of ExxonMobil Low Carbon Solutions. “In addition, the project is expected to enable up to a 30% reduction in Scope 1 and 2 emissions from our Baytown integrated complex, by switching from natural gas as a fuel source to low-carbon hydrogen.”
ExxonMobil will pair the world’s largest low-carbon hydrogen facility with the largest olefins plant in the United States to deliver more sustainable, lower-emissions products for customers and society.
In 2021, ExxonMobil announced Scope 1 and 2 greenhouse gas emission-reduction plans for 2030 for operated assets, compared to 2016 levels. The plans are to achieve a 20-30% reduction in corporate-wide greenhouse gas intensity; a 40-50% reduction in greenhouse gas intensity of upstream operations; a 70-80% reduction in corporate-wide methane intensity; and a 60-70% reduction in corporate-wide flaring intensity.
With advancements in technology and the support of clear and consistent government policies, ExxonMobil aims to achieve net-zero Scope 1 and 2 greenhouse gas emissions from its operated assets by 2050.To learn more, visit exxonmobil.com, the Energy Factor, and ExxonMobil’s Advancing Climate Solutions.
