Assessing Opportunities to Reduce Carbon Dioxide Emissions from Electric Arc Furnace Steelmaking in the United States
Steel is energy- and CO₂ emissions-intensive to produce, but it is also a crucial material for infrastructure, defense, and the energy transition. This thesis focuses on Electric Arc Furnace (EAF) steelmaking, which accounts for roughly 70% of steel production in the United States. Decarbonization …
