United States Steel Corporation (U.S. Steel) and CarbonFree are partnering to capture carbon emissions generated from U. S. Steel’s Gary Works Blast Furnaces. Utilizing CarbonFree’s SkyCycle technology, the project is expected to capture and mineralize up to 50,000 metric tons of carbon dioxide per year, with the opportunity for expansion in subsequent years. This initiative is part of U.S. Steel’s goals to reduce greenhouse gas emissions by 20% by 2030 and achieve net-zero emissions by 2050. Work on the project will begin this year, with operations beginning in 2026. The agreement signed by both companies has a term of 20 years following its in-service date.   

The SkyCycle solution works by capturing carbon emissions before they enter the atmosphere. The emissions are then converted into a carbon-neutral version of calcium carbonate, which can be stored in an environmentally conscious way without the need for pipelines or disposal wells. 

What people are saying

In a recent quote, Scott Buckiso, Senior Vice President & Chief Manufacturing Officer, U. S. Steel, said, “Innovating to capture carbon at an integrated mill is the latest example of how steel is enabling a more sustainable future. Moreover, U. S. Steel has a history of ‘firsts’ that we’re confidently building on. Using SkyCycle technology for the first project of its kind in North America should benefit the community for generations to come.” 

Martin Keighley, CEO of CarbonFree, added, “U. S. Steel is setting a precedent for how manufacturers can and must proactively manage their carbon emissions, and CarbonFree is honored to play a role in this legacy. At CarbonFree, we are pioneering profitable carbon capture utilization through disruptive specialty chemical manufacturing using waste carbon dioxide as a primary feedstock. As carbon capture continues to be recognized as an indispensable solution on the path to carbon neutrality for carbon-intensive industries, we look forward to helping U. S. Steel achieve its decarbonization goals while providing economic and environmental benefits to the city of Gary and state of Indiana.”
