Big Spring Refinery

The Delek US Big Spring Refinery carbon capture project is a DOE-supported commercial-scale deployment of Svante Technologies’ solid sorbent carbon capture system at Delek’s Big Spring, Texas refinery. The project will capture approximately 145,000 metric tonnes of CO₂ per year from post-combustion flue gas produced by the refinery’s fluidized catalytic cracking unit, one of the facility’s largest emission sources. The U.S. Department of Energy selected the project under the Carbon Capture Large-Scale Pilot Program and will provide up to 70 percent cost share funding, capped at $95 million, to support engineering, permitting, and early project development. Svante will supply its second-generation structured sorbent capture technology and modular capture equipment, while Delek will serve as the host site operator and integrate the system into existing refinery operations. Captured CO₂ will be conditioned to pipeline specifications and prepared for transport using existing regional CO₂ infrastructure for permanent geologic storage or utilization. The project is scheduled to advance through detailed engineering and construction phases with initial operations targeted in the 2027–2028 timeframe, positioning Big Spring as one of the first refinery FCC units in the United States to deploy commercial-scale carbon capture technology.
