The steel industry contributes 7-9% of global CO₂ emissions, driving innovation in eco-friendly production. Hydrogen-based steelmaking and carbon capture technologies are revolutionizing traditional methods. Sweden's HYBRIT project successfully produced fossil-free steel in 2021, while recycled scrap steel now accounts for 30% of global production. These advancements align with global climate goals while maintaining steel's crucial role in renewable energy infrastructure like wind turbines and solar panel supports.
