摘要

Being a major contributor to industrial CO2 emissions, the iron and steel industry needs to transition towards CO2-lean processes to achieve the carbon neutrality goal of the European Green Deal for 2050. Process simulation serves as a powerful tool for modelling and evaluating decarbonization strategies in this transition. This contribution explores a potential stepwise decarbonization pathway for the Austrian steel industry using the flowsheet simulation software gPROMS (General PROcess Modeling System). The transition from the carbon-intensive blast furnace (BF)-basic oxygen furnace (BOF) route to electric arc furnace (EAF)-based steelmaking is modelled, integrating hydrogen-based direct reduction (DR) and carbon capture and utilization (CCU) technologies. The analysis evaluates the CO2 reduction potential and the changes in external energy demand for each scenario, including natural gas, electricity, and hydrogen. The findings of this study provide a strong basis for evaluating the European steel industry’s energy demands during its transition towards sustainable steel production.
