ExxonMobil plans a carbon capture project in Southeast Texas, pending state approval, aiming to store CO2 underground across 25,000 acres safely.
JEFFERSON COUNTY, Texas — ExxonMobil is planning a new carbon capture and storage project in Southeast Texas that could begin construction as early as this year, pending state approval.

The company announced plans for the Sunflower Carbon Storage Project, a carbon capture initiative designed to store carbon dioxide underground across approximately 25,000 acres in eastern Liberty County and western Jefferson County.
The project, led by ExxonMobil Low Carbon Solutions, would store captured carbon dioxide between a half-mile and 1.5 miles below the surface in underground reservoirs. Company officials say the storage locations are situated thousands of feet below drinking water aquifers.
Plans also include an 11-mile pipeline extension connecting the storage site to ExxonMobil’s existing pipeline network.
ExxonMobil is seeking a Class VI permit from the Texas Railroad Commission, which regulates underground injection projects and oversees permitting to ensure there is no impact to underground drinking water sources.
Company officials said Southeast Texas and the Gulf Coast were selected for the project due to favorable geology for permanent carbon storage, as well as proximity to industrial customers and existing infrastructure.
If approved, ExxonMobil plans to begin early construction activities in 2026.
