U.S. Steel Signed Agreement with CarbonFree to Cut Emissions at Gary Steel Mill

This plant will test the scalability of the technology so that it could be implemented on a wider scale across U.S. Steel facilities.

SEATTLE (Scrap Monster): Pittsburgh-based integrated steel maker United States Steel Corporation (U.S. Steel) has signed a definitive agreement with CarbonFree- a leader in carbon capture technology, towards capturing carbon emissions generated from U. S. Steel’s Gary Works Blast Furnaces.

According to company news release, the project will make use of CarbonFree’s SkyCycle technology to capture and mineralize up to 50,000 metric tons of carbon dioxide per year. This is equivalent to annual emissions generated by approximately 12,000 passenger cars. The two companies plan to expand the project over the next few years.

The construction works on the proposed SkyCycle plant in the U. S. Steel Gary Works facility is expected to commence this summer, with operations expected to begin in 2026. This plant will test the scalability of the technology so that it could be implemented on a wider scale across U.S. Steel facilities.

The definitive agreement is part of U.S. Steel’s previously stated goal of reducing greenhouse gas emissions intensity by as much as 20% by 2030 and achieving net-zero emissions by 2050.

The patented SkyCycle technology captures carbon emissions from hard-to-abate industrial sources and converts them into a carbon-neutral version of calcium carbonate, which in turn will be used to create various products.
