US Steel to Capture Emissions From Indiana Plant
United States Steel Corporation signed a non-binding Memorandum of Understanding (MoU) to pursue the capture of CO2 emissions generated from U. S. Steel’s Gary Works manufacturing plant.
The MOU was signed with CarbonFree Chemicals Holdings, LLC using CarbonFree’s SkyCycle™ technology. If a definitive agreement is reached, the project is expected to capture and mineralize up to 50,000 metric tons of CO2 per year.
CarbonFree’s patented SkyCycle technology captures carbon emissions from hard-to-abate industrial sources before entering the atmosphere, converts the CO2 into the specialty chemical precipitated calcium carbonate (PCC), and produces hydrochloric acid (HCl) as a co-product.
Located in Gary, Indiana, U. S. Steel’s Gary Works has annual production capability of 7.5 million net tons of raw steel per year. The MoU establishes a framework for discussions regarding the formation of a commercial venture.
The decision between CarbonFree and U. S. Steel to enter into a definitive agreement is expected to be made prior to the end of 2023, and if a final agreement is executed, the parties are targeting 2025 for commencement of operations.
“We are eager to enter the next phase of discussions with CarbonFree to explore the possibility of meaningful CO2 emission reductions in our operations in a capital efficient manner,” said Richard L. Fruehauf, SVP – Chief Strategy & Sustainability Officer at U. S. Steel in a statement. “Working with CarbonFree could be a meaningful step in our efforts to decarbonize the Gary Works plant while developing technology and knowhow that we could apply to other facilities within our footprint.”
