steelTalks is a monthly series on topics of interest to the global steel community. The lectures are presented in a webinar format with a guest lecturer. In this steelTalk, Prof. Valentina Colla, Associate Professor of Metallurgy at Scuola Superiore Sant’Anna (Italy), will present an overview of hydrogen-enriched DR and its associated challenges, while outlining additional technologies that can support decarbonisation efforts in steel production.

Description
Direct Reduction (DR) of iron ore is a widely recognized commercial route to reduce CO₂ emissions in integrated steelmaking. However, it relies heavily on natural gas — a resource that is limited in many regions.
Hydrogen-enriched DR, which increases the share of hydrogen as a reducing agent in the process, offers significant potential to further cut CO₂ emissions and decrease dependence on natural gas markets. Yet, scaling up hydrogen-enriched DR poses substantial techno-economic challenges that require complementary measures to ensure a sustainable transition.
In this steelTalk, Prof. Valentina Colla, Associate Professor of Metallurgy at Scuola Superiore Sant’Anna (Italy), will present an overview of hydrogen-enriched DR and its associated challenges, while outlining additional technologies that can support decarbonisation efforts in steel production.
What you will learn
• Understand the fundamentals of hydrogen-enriched direct reduction.
• Learn about the main challenges in scaling up hydrogen-based DR.
• Explore complementary measures that can support a sustainable transition to hydrogen-based steelmaking.
