  • POSCO Holdings joined South Korea’s K-GX signature “Steel GX” project, outlining a plan to shift steelmaking toward decarbonized production.
  • The strategy centers on HyREX hydrogen-based steelmaking, paired with government-backed clean power and clean hydrogen supply to support 24/7 operations.
  • POSCO set a target to build a 300,000-ton-a-year HyREX pilot facility in Pohang by 2028 as the first phase.
  • The company projected KRW 6 trillion in economic impact, 14,000 jobs, and 560,000 tons of annual carbon cuts from the southeast cluster.
  • Expansion is planned from the Pohang-led southeast cluster to a Gwangyang-led southwest hub, contingent on validating the initial model.
