Key Industry Development:

In April 2024, ArcelorMittal, one of the world’s leading steelmakers, developed a new type of steel that showed potential for reducing corrosion in offshore applications. This innovative steel was presented in an award-winning poster at Wind Europe 2024 in Bilbao, Spain, in April 2024. ArcelorMittal’s senior project engineer, Krista Van den Bergh, highlighted the unique challenges faced by steel structures in offshore environments, including the aggressive conditions caused by seawater and atmospheric chlorides. The new steel aimed to address these issues by minimizing corrosion, which could enhance the longevity and reliability of offshore wind turbine foundations and other related structures.

In December 2023, U.S. Steel, the storied Pittsburgh steel producer that had played a pivotal role in the nation's industrialization, was acquired by Nippon Steel in an all-cash deal valued at approximately $14.1 billion. Including the assumption of debt, the transaction amounted to about $14.9 billion. This acquisition positioned the combined company among the top three steel producers globally, based on 2022 figures from the World Steel Association. The price for U.S. Steel was nearly double the amount previously offered by Cleveland Cliffs just four months earlier, an offer U.S. Steel had rejected.
