POSCO opens Korea's largest electric arc furnace to cut carbon emissions and fight Chinese steel oversupply

POSCO has started up South Korea's largest electric arc furnace, a $400 million facility with 2.5 million tons of annual capacity. The shift from traditional blast furnaces to electric arc steelmaking cuts carbon emissions significantly, especially when paired with clean electricity. The move comes as the K-Steel Act takes effect, offering policy support to steelmakers facing Chinese oversupply and weak domestic demand. Electric arc furnaces can reduce steelmaking emissions by up to 75% compared to blast furnaces if powered by renewable energy. This is a concrete step toward decarbonizing one of the hardest-to-abate industrial sectors. The article is worth reading for anyone tracking industrial decarbonization, carbon border adjustments, or how major steel producers are adapting to tightening carbon rules. For carbon market participants, this signals potential shifts in steel supply chains and demand for green steel premiums. It also raises questions about how South Korea's emissions trading system will treat electric arc furnace output versus traditional methods.

POSCO firing up a 2.5M ton electric arc furnace is a big deal for industrial decarbonization. EAF steelmaking can cut emissions 60-75% versus blast furnaces if the electricity is clean. Curious what their power mix looks like for this facility.

The K-Steel Act timing matters. Policy support for EAF expansion could accelerate scrap-based steel production in Korea. But Chinese oversupply still looms. Need to see if carbon border adjustments make green steel competitive.

2.5M tons of EAF capacity needs a lot of electricity. At roughly 500 kWh per ton, that is around 1.25 TWh annually. Does Korea have the grid capacity and renewable generation to make this actually low carbon? Or is it just shifting emissions to the power sector.

POSCO also has the HyREX hydrogen direct reduction project in the works. This EAF is probably a bridge while they scale hydrogen-based steelmaking. Still, 400 million is real money and 2.5M tons is real capacity.

Worth watching how Korea's ETS treats EAF steel versus blast furnace output. If the carbon price is high enough, the economics shift hard toward scrap-based routes. The K-Steel Act subsidies might distort that signal though.
