The reduction of carbon emissions from the process of making steel is known as steel decarbonization. Also, by focusing on changing the toxic gas emission process, the steel decarbonization has gained major industry attention in recent years. Moreover, the steel makers have seen using cleaner methods by using electricity, hydrogen fuel, and recycled steel in recent years.
The industry is heavily moving from a single dominant method to multiple flexible methods. Earlier, most steel came from one main process based on coal. Now, the industry is exploring different paths like electric-based production, hydrogen-based methods, and high recycling systems. This shift is important because there is no one perfect solution for all regions.
