Electra’s Innovative Approach to Revolutionizing Ironmaking
Have you ever wondered about the environmental impact of the ironmaking industry? Well, Electra is taking significant strides to address this issue, having recently raised $76.3 million to transform this traditionally polluting sector. By harnessing electricity, Electra has developed a groundbreaking method to extract pure iron from low-grade ores, paving the way for cleaner steel production.
This newly disclosed funding round aims to gather a total of $256.7 million, as noted in a regulatory filing. The importance of such innovations cannot be overstated—iron production is a major culprit behind the high emissions associated with steelmaking, which contributes to 7% of global carbon emissions. The conventional method involving blast furnaces fueled by fossil fuels has remained largely unchanged for centuries.
A Shift Towards Cleaner Practices
As industries strive for sustainability, alternatives are being actively sought. Electra’s solution lies in electrowinning, a technique already used for metals like copper and nickel. This process utilizes an electric current to draw metal from a liquid solution, with the metal plating onto an electrode and impurities settling at the tank’s bottom.
- Electrowinning is now being adapted for iron.
- This innovation uses lower-grade ores, making it cost-competitive.
- The process operates at around 60 degrees C, more efficient than traditional methods.
“With electrowinning and electric-arc furnaces, we could potentially eliminate most carbon emissions from steelmaking,” an expert noted.

Electra’s unique acid-based process can handle lower-grade ores efficiently by heating the solution just below water’s boiling point and passing a current through it. The resulting iron plates serve as ideal feedstock for electric-arc furnaces that can also operate on renewable energy sources.
The Road Ahead
When combined, electrowinning and electric-arc furnaces present a promising path towards significantly reducing carbon emissions in steelmaking. Electra previously secured $85 million in 2022 from notable investors such as Amazon and Breakthrough Energy Ventures. While the company hasn’t commented on this latest development yet, it’s clear that they’re on a mission to revolutionize an industry ripe for change.
