LSB Industries' Arkansas CCS Well Puts Blue Ammonia Within Reach

A well drilled deep into the Arkansas earth could be the starting point for a cleaner chapter in U.S. ammonia production. LSB Industries has completed a stratigraphic injection well at its El Dorado ammonia facility, a concrete step toward sequestering hundreds of thousands of metric tons of CO2 annually. It's the first project of its kind in Arkansas, and it shows the state is serious about industrial decarbonization.

The well was completed in June 2025 by CCS partner Lapis Carbon Solutions, which is covering 100% of the capital investment for the capture infrastructure, pipeline, and injection well. Lapis resubmitted the pre-construction Class VI permit application to the U.S. EPA in December 2025, with approval expected in Q4 2026.

Once operational, the project would give the growing blue ammonia market yet another real, production-scale proof point.

A Partnership Built for Scale

LSB Industries is one of the largest ammonia and derivatives producers in the United States, with roughly 900,000 tons of annual production across facilities in Arkansas, Alabama, and Oklahoma. Its El Dorado plant sits on 1,400 acres above deep saline reservoirs capable of storing decades of CO2. The captured gas will be compressed into liquid form and injected into the Hosston and Cotton Valley geological formations, roughly 3,500 to 6,500 feet below surface, below a 1,000-foot-thick impermeable shale barrier.

Lapis entered a project development agreement with LSB in 2022 and handles the full CCS stack. The El Dorado well provides the geological data the EPA needs to finalize its Class VI review, and is designed to serve double duty as the operational injection well once permits are secured.

IRA Incentives Sharpen the Business Case

The timing aligns with strong policy tailwinds. The Section 45Q tax credit, preserved under the One Big Beautiful Bill Act signed July 4, 2025, offers up to $85 per metric ton for CO2 permanently stored at point-source industrial facilities. For a project sequestering up to 500,000 metric tons annually, that adds up fast.

LSB already has a commercial anchor, too. A five-year offtake agreement with Freeport Minerals Corporation covers up to 150,000 short tons of low-carbon ammonium nitrate solution per year for use as a blasting agent in copper mining. That deal puts blue ammonia demand squarely in the industrial sector, proving it's not just an agriculture story.

One Well, Many Implications

Arkansas isn't typically associated with the energy transition, but El Dorado is quietly putting it on the map. Being first in the state, and only third nationally from ammonia production, gives LSB and Lapis a real head start in a space where early movers build lasting advantages.

The carbon capture sector has been searching for retrofit success stories at commercial scale. With the well drilled, the permit resubmitted, and a paying customer already locked in, El Dorado is shaping up to be exactly that. It's proof that decarbonizing hard-to-abate industry doesn't always require new technology. Sometimes the answer is right beneath the existing facility.
