European Direct Reduced Iron and Alternative Ironmaking Conference - IRONMASTERS 2022

The steel industry contributes with around 6% to the worldwide anthropogenic emissions of CO2. Therefore, it is clear that new ways of steel production need to be investigated. One promising technology is the so-called Hydrogen Plasma Smelting Reduction (HPSR), which not only produces steel without the usage of fossil fuels but also is a one-step process from iron ore towards steel. In this, study the circumstances of steel production in Europe and the current state of development of the HPSR process are shown. Aside also, the basic concept and the thermodynamics and kinetics are shortly explained. Furthermore, some detailed information about the field of upscaling research in connection to the arc geometry of the plasma is presented.
