Hydrogen-Based DRI EAF Steelmaking - Fact or Fiction?

摘要

This paper will present a provocative rumination of the challenges to be considered and overcome before hydrogen-based direct reduced iron (DRI) steelmaking becomes a reality, or not. Considerations such as technology needs (H2 generation, DRI carbon content, electric arc furnace needs and overall carbon balance) and economic viability (as understood currently) will be posed and discussed, along with the impact of carbon taxes.
