Edgar Thomson CCS

GTI Energy will partner with U.S. Steel Corporation to advance the ROTA-CAP™ carbon dioxide (CO2) capture system to pilot scale (3 tonnes of CO2 captured/day). The project objectives are to design, build and operate an engineering-scale plant at U.S. Steel’s Edgar Thomson industrial iron and steel production facility in Braddock, Allegheny County, Pennsylvania. The project will be supported by Holcim US Inc., Enbridge Gas Inc., and Low Emission Technology Australia (LETA), with a goal to demonstrate that the capture system captures 95% of the CO2 from the industrial gas slipstream and produces a 95% pure CO2 stream. GTI Energy has completed more than 1,600 hours of testing with their skid-scale (1-tonne CO2/day) ROTA-CAP system at the National Carbon Capture Center (NCCC), with feed gas varying from 4% to 22% CO2, exhibiting up to 95% capture efficiency.
