ExxonMobil announced that it has begun transporting and storing captured CO2 from the New Generation Gas Gathering (NG3) project in Gillis, Louisiana.
NG3 is the company’s second active commercial carbon capture and storage (CCS) operation in Louisiana.
Natural gas produced from East Texas and Louisiana is gathered through the NG3 gathering system for treatment at the NG3 Gillis facility, where up to 1.2 million mtpa of CO2 is expected to be removed from the natural gas stream before the product is redelivered to Gulf Coast markets, including liquefied natural gas (LNG) facilities.
This startup is Exxon’s second active commercial CCS operation in Louisiana. In July 2025, the company began transporting and storing CO2 from CF Industries’ Donaldsonville Complex, enabling the production of low-carbon ammonia.
Exxon said it has two more CCS projects set to start in 2026. The CO2 contracted for the two active projects, the company said, accounts for up to 3.2 mtpa, approximately one-third of its committed CCS volumes. Exxon is currently storing the CO2 from both projects in permanent geologic sites through enhanced oil recovery and said it has plans to transition to dedicated permanent storage.
Louisiana’s geology and industrial and energy infrastructure, Exxon said, make it well-positioned for CCS, which is already being integrated into key industries such as ammonia, gas, and LNG through the CF and NG3 projects.
The ability to produce low-carbon products through CCS is also attracting large-scale industrial projects such as data centers. Louisiana has already seen about $61 billion invested into emissions-reduction projects.
