CarbonFree窶冱 patented SkyCycletechnology 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.

窶廣s we aim to widely introduce and scale our technology to industrial facilities across the globe, we are thrilled for the possibility of bringing our SkyCycle technology窶冱 carbon capture capabilities to ｰﾙﾃﾄｵｼｺｽ窶冱 Gary Works plant, one of the largest integrated steel mills in North America,窶� said Martin Keighley, CEO of CarbonFree. 窶弩e are committed to working closely with ｰﾙﾃﾄｵｼｺｽ to achieve their sustainability goals and to further our mission of helping to enable the world窶冱 transition to net zero carbon emissions.窶�

Located in Gary, Indiana, ｰﾙﾃﾄｵｼｺｽ窶冱 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 ｰﾙﾃﾄｵｼｺｽ 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. The parties may also consider collaborating on more carbon capture, utilization and storage projects in the future.

窶弩e are eager to enter the next phase of discussions with CarbonFree to explore the possibility of meaningful CO₂emission reductions in our operations in a capital efficient manner,窶� said Richard L. Fruehauf, SVP 窶� Chief Strategy & Sustainability Officer at ｰﾙﾃﾄｵｼｺｽ. 窶弩orking 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. These potential collaborations are critical to ｰﾙﾃﾄｵｼｺｽ as we continue our mission of providing profitable steel solutions for people and planet.窶�

SkyCycle technology is modular, scalable and patented and is designed to directly capture CO₂emissions from industrial emitters. The technology produces PCC for sale into the global specialty chemicals market, and calcium carbonate for the sequestration of CO₂. PCC is a high-value product used for a variety of industrial purposes, including in the manufacturing of paper, plastics, ceramics, paints, coating, adhesives, sealants, rubber and cleaning products. Additionally, CO₂ that is converted to calcium carbonate can be permanently stored as an environmentally friendly mineral.
