Liberty Steel is increasing production capacity at its Whyalla plant by constructing a new electric arc furnace (EAF) to be filled with scrap and other ferrous materials from its subsidiary Simec Mining and local scrap metal suppliers.
EAF is expected to achieve a 90% reduction in direct carbon emissions by 2025 compared to conventional blast furnace production. The construction of the furnace is planned to be completed in 2025, along with the renewal of the existing coke and blast furnaces.
Liberty Steel also plans to build a direct reduction plant (DRP) that can process local magnetite ore to produce direct reduced iron (DRI).
DRP will initially use a mixture of natural gas and green hydrogen, and will then switch entirely to hydrogen as it becomes available at scale.
These developments are part of Whyalla's CN30 plan, which aims to increase magnetite production to 15 million tons per year, to 10 million tons of DRI per year for green steel production and export in the country. Liberty Steel is phasing out coal-based steel production at its Australian plant.
