Low temperature electrolysis (<110°C)


Technology Description

The electrolytic steelmaking process uses renewable electricity to transform iron oxides into pure metals. Low temperature electrolysis (<110°C) is one of the two main types of such electrolysis, generally involving extraction from an aqueous solution.

Relevance for Net Zero

The use of renewable electricity would open a fully CO2 free production route for steel, and a reduction of about 30% of energy use compared to standard steel making. It can be designed to respond to electricity grid load balancing to integrate further variable renewables for power generation. However, it is at much earlier stages of development compared to other low emission steel-making technologies.
