In my research, I am investigating the strategic planning of transformation pathways toward low-carbon production processes with energy-intensive industries focusing on primary steelmaking. My research aims to provide decision support for companies to identify economically and ecologically beneficial transformation pathways of integrated production sites. Therefore, I use methods of activity analysis-based modeling, investment and cost calculation, life cycle assessment (LCA), and mathematical optimization. I focus on transforming existing production sites and networks of these industries. Besides technical, economic, and ecological factors, I also consider political aspects, such as the European Emissions Trading Scheme (EU-ETS) mechanisms.
If interested, supporting research activities as part of a student thesis is possible.
