There is no single solution to CO2 -free steelmaking, and a broad portfolio of technological options is required, to be deployed alone, or in combination as local circumstances permit. This series of fact sheets describes and explores the status of a number of key technologies.

At the end of this microlearning you will be able to:
- Describe the fundamental process of electrolysis in ironmaking, including the roles of iron oxide, electricity, and the products generated.
- Identify the environmental benefits of using electrolysis in ironmaking compared to traditional methods.
- Summarize the economic considerations and current challenges associated with the commercialization of electrolysis in ironmaking.
