POSCO Pohang steel plant

From Global Energy Monitor

POSCO Pohang steel plant, also known as Pohang Iron & Steel, is a 17400 thousand tonnes per annum (TTPA) blast furnace (BF) and basic oxygen furnace (BOF) steel plant operating in Pohang, North Gyeongsang, South Korea.


The map below shows the location of the steel plant in Pohang, North Gyeongsang, South Korea.

  • Location: 6262, Donghaean-ro, Nam-gu, Pohang-si, Gyeongsangbuk-do, Republic of Korea[1]
  • Coordinates (WGS 84): 36.009310, 129.394508 (exact)


Construction of the Pohang plant began on 01 April, 1970 and became operational on 03 July, 1973 with a capacity of 1.03 mtpa. After four phases of expansions, the crude steel capacity increased to 9.1 mtpa by 1983.[2] On 29 December, 2021, the blast furnace 1 was permanently shut down. The company announced its plan to turn the furnace into a museum. The plant continues to operate with the remaining three blast furnaces.[3]

POSCO has formulated a 2050 Carbon Neutrality Roadmap, outlining strategies in three core areas: Green process, Green product, and Green Partnership. The goal is to reduce carbon emissions 30% by 2035, 50% by 2040 from average emissions benchmark of 78.8 million tons between 2017-19, and to achieve carbon neutrality by 2050.[4]

On 06 September, 2022, various facilities at the plant was affected during Typhoon Hinnamnor, leading to shutting down of the plant temporarily.[5] The plant resumed operations 135 days after the flood.[6][7]

2050 Carbon Neutrality Roadmap

POSCO is building a first of its kind pilot plant that use fluidized bed reduction reactors (HyREX), developed in collaboration with Primetals Technologies. The construction of the pilot plant with a capacity of 300 ttpa was expected to begin in June 2023.[8]The facility is scheduled for completion in 2026 or early 2027. With HyREX, hydrogen-based direct reduced iron produced will be melted in an electric smelting furnace to produce steel.[9][10] POSCO intends to break ground with a full-scale hydrogen-based steelmaking plants by 2031.[11] POSCO Pohang Works plans to replace its existing production methods with HyREX in 2033.[12][13]

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. Operations were scheduled to start from 2025.[14]

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.[15][16] 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.[17]

POSCO is expanding the highly polluting blast furnace technology overseas to India and Indonesia.[16] Until 2050, POSCO plans on adopting blast furnace-based bridge technologies.[18]
