U of I Leading Carbon Capture Study at Gary Works

By on

The University of Illinois has received a $3.5 million grant from the Department of Energy to complete an advance air capture and storage study at U.S. Steel’s Gary Works facility. The school will conduct research and development to support a front-end engineering design (study on carbon dioxide removal technologies).

The study will focus on the advancement of a direct air capture and utilization system, which can remove 5,000 metric tons per year of CO2 from ambient air and then permanently mineralize it in concrete products. If built, the designed system would be larger than any existing direct air capture system.

“We’re excited to bring together a strong team of academic and industry collaborators to accelerate effective, economical carbon capture and use,” said Dr. Kevin O’Brien, the project’s principal investigator and leader of PRI’s Illinois Sustainable Technology Center. The study will launch at U. S. Steel’s Gary Works in Gary, Ind., using a DAC technology developed by CarbonCapture Inc. The technology will use the plant’s waste heat, energy and location, so energy and transportation costs can be minimized.

“U.S. Steel is committed to progressing our efforts described in our Climate Strategy Report to decarbonize and accelerate towards a lower carbon future, but we know that one company’s actions are not enough,” said Rich Fruehauf, senior vice president – chief strategy and sustainability officer at U.S. Steel. “Achieving our goal of net-zero emissions by 2050 is going to take unprecedented innovation and collaboration.”

Once CO2 emissions are captured from the atmosphere, the liquified gas will be transported to Ozinga ready mix concrete plants utilizing CarbonCure’s CO2 removal and utilization technologies, which inject the CO2 directly into the concrete as it is being mixed. When injected, the CO2 immediately mineralizes and is locked away in the concrete, never to return to the atmosphere.
