2024-02-17

Feb. 17, 2024 - South Korean steelmaker POSCO has begun construction of a 2.5 million tonne per annum electric arc furnace (EAF) at its Gwangyang plant.

The EAF is expected to be completed by the end of 2025 and officially operational in 2026.

The total investment in the project is estimated at KRW 600 billion (over $451 million). When the planned production volume is reached, the company will be able to reduce carbon emissions by about 3.5 million tons per year compared to blast furnace production. In addition, the company intends to use the gases generated during the operation of the electric arc furnace to preheat scrap.

POSCO has ordered a Consteel continuous scrap feeding system and a Consterrer electromagnetic stirring system from Tenova in Italy.

POSCO plans to complete the commercialization of its HyREX technology by 2030 and switch its Pohang and Gwangyang steel mills to steel production based entirely on hydrogen reduction technology by 2050. The company is also stepping up its efforts to establish environmentally friendly commercial production systems abroad. The group plans to double its overseas steel production capacity by 2030 (from 5 million tons in 2022).

As GMK Center reported earlier, POSCO has expressed interest in negotiating potential cooperation with Montenegro’s state-owned energy company Elektroprivreda Crne Gore (EPCG). It concerns the steel branch of Zeljezara Niksic.
