Multicriteria Analysis of Primary Steelmaking Technologies

Enhancing emission efficiency

  • Publications 20.01.2016

To reduce product demand and therefore mitigate the climate impact of the iron and steel industry, four fields of efficiency should be tackled: energy efficiency, emission efficiency, material efficiency and product use efficiency. The paper "Multicriteria Analysis of Primary Steelmaking Technologies" by Max Weigel and Manfred Fischedick (both Wuppertal Institute), Joachim Marzinkowski and Petra Winzer (both Wuppertal University) focuses on one of those four key measures: emission efficiency via innovative primary steelmaking technologies. Four technologies (the blast furnace route, the blast furnace with carbon capture and storage, hydrogen direct reduction, and iron ore electrolysis) are assessed systematically and holistically in Germany, as one possible location. The results aim to provide decision makers in industry and government with a long-term guidance on technological choices.

The paper has been published in the "Journal of Cleaner Production" and is available via ScienceDirect online. Its final draft version can be downloaded from the WI Publication Server.
