  1. 6. Understanding the potential future capacity of distributing green steel solutions - current knowledge and future challenges

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Heba Alwan; [2023]
    Keywords : Carbon dioxide CO2 ; greenhouse gas GHG emissions; Steelmaking fossil-free; direct hydrogen reduction; Sustainability transitions.;

    Abstract : Transitioning from the conventional steel process to a direct hydrogen reduction process in the steel industry is a significant step towards reducing carbon dioxide emissions and achieving greater sustainability. The process involves using hydrogen gas as a reducing agent instead of carbon to remove oxygen from the iron ore. READ MORE

    Abstract : Steel production is today one of the most CO2-demanding activities and causes 8% of the global emissions of GHG. It is crucial for the industry to reduce its emissions radically in order to be in line with the goals of the Paris Agreement and the Science-Based Target initiative. READ MORE

  5. 9. Influence of coal particle sizes on the mechanical strength of iron-carbon briquettes : With focus on steelmaking applications

    University essay from KTH/Materialvetenskap

    Author : Daniel Zaharije Hodgson; Efe Karadag; Maxime Pierre Jean-Claude Saillen; [2022]
    Keywords : ;

    Abstract : Replacing fossil carbon materials with renewable biocarbon is one way to reduce the net carbon dioxide emissions of the iron and steelmaking industry. Carburization is an important application in the electric arc furnace (EAF), and is mostly achieved by adding fossil-based carbon materials into the melt today. READ MORE

  6. 10. Integrating CO2 Utilisation and Biomass Gasification with Steel-making Electric Arc Furnaces (EAF)

    University essay from KTH/Energiprocesser

    Author : Adel Mokhtari; [2022]
    Keywords : biomass gasification; carbon capture and utilization CCU ; process integration; electric arc furnace EAF ; EAF off-gas;

    Abstract : Without a doubt, there is a consensus around the international community which suggests that our current way of life is unsustainable for a healthy planet, society and economy. One focal point that should be taken deeply into consideration is the steel industry as, globally, it accounts for 8% of global emissions. READ MORE
