Energy firm ExxonMobil has announced plans to deploy Honeywell’s carbon capture technology at its integrated complex in Baytown, Texas.

The technology, called CO2 Fractionation and Hydrogen Purification System, is expected to help ExxonMobil capture approximately 7 million tons of carbon dioxide (CO2) per year, which is equivalent to the annual emissions of 1.5 million automobiles.

According to ExxonMobil, it will also integrate a Honeywell UOP carbon capture technology into the design of its low-carbon hydrogen production facility to capture more than 982 percent of associated CO2 emissions. It plans to sequester and permanently store the captured CO2.

“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 hydrogen.”

At its Baytown integrated complex, ExxonMobil says it is planning to launch the world’s largest low-carbon hydrogen project in 2027-2028, with the capacity to produce around one billion cubic feet of low-carbon hydrogen per day. Sited on approximately 3,400 acres along the Houston Ship Channel, the Baytown ammonia and carbon capture facility is said to be home to the largest olefins plant in the U.S.

“The use of Honeywell’s technology enables ExxonMobil to reduce CO2 emissions at a large scale,” said Barry Glickman, Vice President and General Manager of 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.”
