Japanese Owner Unveils Decarbonization Plan for Košice Steel Plant with Single Electric Arc Furnace

Nippon Steel, the Japanese owner of Košice steel works, has announced plans to install one new electric arc furnace to replace part of the facility's coal-based production, marking a shift from the previous American owner's more ambitious replacement strategy. The single new furnace will be capable of producing up to 47 percent of the plant's current steel output, while requiring an investment of hundreds of millions of euros. The project aims to reduce carbon dioxide emissions by 56 percent and nitrogen oxide emissions by 25 percent compared to current operations. The decarbonization initiative represents a more measured approach than the previous plan by former American owner U.S. Steel, which had proposed replacing two of the plant's three blast furnaces with electric alternatives. The Košice steel works is one of Slovakia's largest industrial facilities and a major employer in the eastern region, making its environmental modernization significant for both local economic stability and the country's climate commitments.
