ArcelorMittal

ArcelorMittal is the world’s largest steel producer and a key actor in the decarbonization of Europe’s steel sector. The company is investing in hydrogen-based direct reduced iron, electric arc furnaces, and carbon capture to cut emissions from coal-based blast furnaces. While it benefits from substantial EU and national public funding, large-scale deployment remains constrained by high operating costs, electricity prices, and uncertainty over the availability of green hydrogen at scale. ArcelorMittal’s transition pathway is widely viewed as a benchmark for assessing whether low-carbon steel production can be scaled competitively in a global market.
