Background

POSCO Gwangyang plant was constructed in four phases between 1982 and 1992.[1] POSCO Gwangyang houses five out the fourteen blast furnaces larger than 5500 m3 in the world.[2][3] Blast furnace #3 was restarted in July 2020 after being rebuilt for the third time.[4] Blast furnace #3 added 4.6 mtpa crude steel capacity to POSCO Gwangyang steel plant, bringing the plant's crude steel capacity up from 18 mtpa to 23 mtpa to become the largest steel plant in the world in 2016.[4][5] A steel mill in China (Zhangjiagang Hongchang Steel Co., Ltd.) has since exceeded the capacity of the POSCO Gwangyang steel plant.[6]

In November 2020, three workers were killed in an explosion at POSCO Gwangyang.[7]

2050 Carbon Neutrality Roadmap

POSCO is also planning to invest in an electric furnace (EAF) each for its Pohang and Gwangyang steelworks. The expansion project is expected to produce 2.5 million tonnes of hot metal annually with the aim of achieving carbon neutrality. The news article from May 2023, mentioned that it was unlikely that annual crude steel production will increase from the two facilities.[8] Operations were scheduled to start from 2025.[8]

In June 2023, POSCO Gwangyang placed an order with Tenova for an Electric Arc Furnace equipped with Consteel and Electromagnetic Stirrer Consteerrer, as part of it decarbonisation pursuit. The EAF with capacity of 2500 ttpa is expected to enter service by the end of 2025.[9][10][11]

Under the company's 2050 carbon neutrality roadmap POSCO plans to phase-out traditional blast furnace technology by 2050 and adopt renewable and green hydrogen-based steelmaking technology in its plants in South Korea.[12][13] POSCO plans to develop the hydrogen reduction steel plant by reclaiming land from sea which is expected to be completed by 2041 and begin full operation of hydrogen reduction steel facility by 2050.[14][15]
