According to the oil and gas major, the project planned for its Baytown plant, originally announced in 2022, will be the ‘largest’ low-carbon hydrogen project in the world, with start-up expected in 2027-2028.

More than 98% of the associated carbon dioxide produced by the facility – around seven million tonnes per year – is expected to be captured and permanently stored, ExxonMobil has said.

The company added, the carbon capture and storage (CCS) network being develop for the project will be made available for use by third-party carbon emitters in the area to support their decarbonisation efforts.

Dan Ammann, President of ExxonMobil Low Carbon Solutions said the project is hoped to enable a 30% reduction in Scope 1 and 2 emissions from the company’s Baytown complex by switching from natural gas as a fuel source to low-carbon hydrogen.

H2 View understands ExxonMobil will pair the low-carbon hydrogen facility with the ‘largest’ olefins plant in the US to deliver more sustainable, lower-emissions products for customers.

Additionally, Ammann explained, “This project allows us to offer significant volumes of low-carbon hydrogen and ammonia to third party customers to support their decarbonisation efforts.”
