Abstract.
Accounting for 6–7% of global greenhouse gas (GHG) emissions, the steel industry and its supply chain emit more CO2e (CO2 equivalent) than any other metal produced. Steel is a “hard-to-abate” industry due to its reliance on carbon to reduce iron ore to iron. Steel demand will grow due to population growth, implementation of renewable energy systems, and a need for resilient infrastructure. The steel industry must reduce GHG emissions while increasing output by more than 30% by 2050. This paper describes the expected technology changes and related challenges that face the steel industry on its journey to net zero GHG emissions.
