How does fossil-free steel work ? [Green Steel in a Nutshell | Hydrogen Steelmaking]

The steel industry is undergoing significant changes. Given my work experience and PhD in the field, you asked for more detail in the last video on fossil-free steel. There you go!
Imagine a world without steel. Jokes aside, why can’t we replace steel with another more sustainable material?
In this video we’ll dig deep into what makes steel unique from the bottom up building the foundation for the urgency of the steel sector’s decarbonization. And show what's possible with the low-carbon technologies that are being deployed in steelmaking.
