Low-Carbon Production of Iron & Steel: Technology Options

 · Direct Reduced Iron (DRI): This iron production process directly reduces iron ore in solid-state with the reaction temperature below the melting point of iron. Reducing gases are produced from natural gas (gas-based DRI) or coal (coal-based DRI) called syngas, a mixture of H2 and CO. Although DRI production is more energy efficient than pig iron production from
