To mitigate the significant carbon footprint of traditional ironmaking, this study evaluates four advanced direct reduced iron (DRI) systems powered primarily by biomass. These innovative systems employ chemical looping technology and CO2 capture techniques to produce carbon-negative iron. Detailed system modeling, optimization, and thermodynamic evaluations have been performed to analyze exergy flows, energy consumption composition and carbon emissions.
