Hydrogen Direct Reduction: History and Pathways for Cost Reduction
cScience, Volume 1, Issue 1, December 2025.ABSTRACT The steel industry, a critical pillar of global economic development, is highly energy‐intensive, accounting for approximately 7%–9% of global energy‐related CO2 emissions. The transition from traditional carbon‐intensive metallurgy to hydrogen‐based metallurgy represents a pivotal pathway for the green and sustainable development of the steel

Results of Hydrogen Reduction of Iron Ore Pellets at Different Temperatures
steel research international, Volume 96, Issue 5, May 2025.Using hydrogen as a reductant in DRI units is the steelmaking industry's future, significantly reducing CO2 emissions. Hydrogen‐based reduction depends on the temperature. High temperature can lead to a high reduction degree; however, this may also bring some change in the porosity and microstructures of pellets.
