Voestalpine Texas Carbon Capture Project

The ArcelorMittal Texas HBI Carbon Capture Project is a Front-End Engineering and Design study evaluating large-scale post-combustion CO₂ capture at the ArcelorMittal Texas hot briquetted iron facility near Corpus Christi, Texas. The project targets capture of approximately 95 percent of the plant’s main CO₂ emissions, equivalent to roughly 1 million tonnes of CO₂ per year, using Air Liquide’s Cryocap™ FG technology combined with pressure swing adsorption pre-concentration. The capture system is designed to treat flue gas streams from the MIDREX® HBI production process and deliver compressed CO₂ at pipeline-ready pressures of 2,100 to 2,200 psig with product purity exceeding 95 percent CO₂ by volume. The FEED study is funded under a U.S. Department of Energy NETL award with a total project budget of $4.95 million, including a 20 percent non-federal cost share, and is scheduled to run from April 2023 through mid-2025. Engineering scope includes full capture plant integration, compression and dehydration systems, heat recovery optimization, water sourcing design, and balance-of-plant infrastructure to support long-term operation. The site’s proximity to multiple developing CO₂ storage hubs in the Port of Corpus Christi region positions the project for future connection to permanent geological sequestration networks, enabling large-scale industrial decarbonization of direct reduced iron production
