Honeywell announced that ExxonMobil will deploy one of Honeywell’s carbon capture technologies—Honeywell’s CO₂ Fractionation and H₂ Purification System—at its integrated complex in Baytown, Texas. This technology is expected to enable ExxonMobil to capture about 7 MMtpy of CO₂, the equivalent of the emission of 1.5-MM automobiles for one year.

Honeywell UOP’s carbon capture technology will be integrated into the design of ExxonMobil’s low-carbon H₂ production facility and enable it to capture more than 982% of associated CO₂ emissions. The captured CO₂ is expected to be sequestered and permanently stored by ExxonMobil.

ExxonMobil’s Baytown low-carbon H₂, ammonia and carbon capture facility is expected to produce around 1 Bft³d of low-carbon H₂, making this the largest low-carbon H₂ project in the world at planned startup in 2027-2028. ExxonMobil’s Baytown integrated complex is home to the largest olefins plant in the U.S. The site is located on approximately 3,400 acres along the Houston Ship Channel.

“ExxonMobil’s investment in carbon capture technology shows our commitment to supporting customers in their decarbonization efforts and to reducing emissions at our own operations,” said Dan Ammann, president of ExxonMobil Low Carbon Solutions. “The scale of this project is expected to enable up to 30% of Scope 1 and 2 emissions from our Baytown facility by switching from natural gas as a fuel source to low-carbon H₂.”

“The use of Honeywell’s technology enables ExxonMobil to reduce CO₂ emissions at a large scale,” said Barry Glickman, vice president and general manager, Honeywell Sustainable Technology Solutions. “Our ready-now carbon capture technology works to decarbonize production processes and is effective because it can allow for significant emissions reduction that can play a major role in the energy transition.”
