• Fact sheet Hydrogen (H2)based ironmaking

    chemically reduced from iron ore through the use of fossil resources – natural gas or coal. This process is known as Direct Reduced Ironmaking (DRI). Carbon combines with the oxygen in the iron ore, producing metallic iron and a carbonrich process gas, according to the following simplified chemical reaction: 2Fe 2 O 3 + 3C > 4Fe + 3CO 2 Currently, for every tonne of iron that is produced ...

     · The second way to produce iron is through direct ore reduction using gas. Syngas and natural gas have long been used in these processes, but the focus has now shifted to the use of hydrogen, which offers nearzero Scope 1 emissions. However, at the moment it is a tradeoff with higher Scope 2 emissions from hydrogen produced from natural gas.

  • Direct Reduced Iron (DRI)

    Directreduced iron (DRI), also called sponge iron, is produced from direct reduction of iron ore (in the form of lumps, pellets or fines) by a reducing gas produced from natural gas or coal. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent. This process of directly reducing the iron ore in solid form by reducing gases is called ...
