In partnership with ExxonMobil, the facility is a major step forward in carbon capture and storage (CCS) in the U.S. ammonia sector—helping CF Industries produce approximately 1.9 million tons of low-carbon ammonia annually while qualifying for Section 45Q tax credits.
“By starting permanent sequestration now, we reduce our emissions, accelerate the availability of low-carbon ammonia for our customers, and begin generating valuable 45Q tax credits,” said Tony Will, CEO of CF Industries.
From Concept to Execution
The Donaldsonville facility marks a shift in CCS from pilot stage to industrial-scale deployment in the U.S. fertilizer sector.
Ammonia Export Opportunity
Rising global demand—particularly from Japan, South Korea, and the EU—for low-carbon hydrogen carriers positions the U.S. as a blue ammonia exporter.
Tax Credits as Economic Driver
Section 45Q provides up to $85 per ton for CO2 stored in saline formations. If fully utilized, CF Industries could receive approximately $170 million annually, reshaping CCS economics.
Strengthening the Gulf Coast CCS Hub
With ExxonMobil’s Rose project and other Class VI permit applications in progress, the Gulf Coast is emerging as a key region for U.S. CCS development.
Despite its promise, the project raises critical environmental and regulatory concerns.
Enhanced Oil Recovery (EOR) Use
Although ExxonMobil plans to transition to dedicated storage, the current use of EOR—injection of CO2 to extract oil—raises questions about climate benefits. Critics say this undermines net-zero goals.
Environmental Justice in Cancer Alley
Donaldsonville lies within Louisiana’s heavily industrialized “Cancer Alley.” CCS may reduce CO2 but does not address toxic co-pollutants like NOx and particulates. Community advocates warn the project could prolong harmful local emissions.
Long-Term Storage and Leakage Risk
Studies by the IPCC and National Academies highlight the potential for CO2 leakage and stress the need for rigorous, decades-long monitoring. While the EPA’s Class VI well program sets strict standards, implementation has been slow.
Financial Dependence on 45Q Subsidies
The business case hinges on 45Q tax credits, which expire in 2033. If the political environment changes or incentives drop, the facility’s long-term economics could falter.
Green Hydrogen Delay
While blue ammonia is cleaner than conventional ammonia, it still relies on fossil fuel-derived hydrogen. Experts caution that overinvesting in blue hydrogen may delay the infrastructure and scale-up needed for truly green alternatives.
The Donaldsonville CCS facility positions CF Industries at the forefront of blue ammonia production and offers a commercial model for industrial decarbonization. But it also reflects the nuanced reality of the energy transition—where carbon reductions, community impact, and financial structures are tightly intertwined.
As ExxonMobil’s Rose site awaits EPA approval and global markets ramp up demand for clean hydrogen carriers, Donaldsonville stands as a test case for how—and how quickly—carbon capture can scale in high-emissions sectors.
