ExxonMobil has begun transporting and storing captured CO2 from the New Generation Gas Gathering (NG3) project in Gillis, Louisiana, marking its second active commercial carbon capture and storage (CCS) operation in the state.
The startup strengthens Louisiana’s growing role as a US hub for CCS deployment across LNG, natural gas processing and other hard-to-abate industrial sectors.
Natural gas produced in East Texas and Louisiana is gathered through the NG3 system and treated at the Gillis facility, where up to 1.2 million tons of CO2 per year is removed from the gas stream before the product is delivered to Gulf Coast markets, including LNG export terminals.
The captured CO2 is transported and injected into geologic formations for long-term storage, with current operations utilising enhanced oil recovery and plans to transition toward dedicated permanent storage.
Real progress in Louisiana’s CCS buildout
The NG3 startup follows ExxonMobil’s July 2025 launch of CO2 transport and storage for the CF Industries Donaldsonville complex, enabling the production of lower-carbon ammonia.
Together, the two active projects represent up to 3.2 million tons per year of contracted CO2 volumes, accounting for roughly one-third of the company’s current committed CCS capacity across the US Gulf Coast.
ExxonMobil says two additional CCS projects are scheduled to start operations in 2026, adding to a growing portfolio spanning ammonia, natural gas processing, steel, methanol, industrial gases and power generation.

The company now holds contracted CO2 volumes across more industrial sectors than any other CCS developer in the region, reflecting rising demand for decarbonisation pathways that preserve industrial competitiveness.
Louisiana’s combination of favorable subsurface geology and dense energy infrastructure positions the state as a strategic CCS hub.
Beyond lowering emissions from LNG and ammonia, access to CCS is also becoming a factor in attracting new industrial developments, including energy-intensive data centers seeking lower-carbon power and fuels. As more projects reach operation, CCS is emerging as a core pillar of Louisiana’s industrial decarbonization strategy, enabling emissions reductions while sustaining regional economic growth.
