Metal Oxide Electrolysis

We transform dirt to metal very efficiently

Molten Oxide Electrolysis (MOE)

Better quality, easier process, no hazardous waste, pure metal output.


Reducing Agent Electrons
Feedstock Concentrates or pure oxides
Electrolyte Molten oxides (CaO, MgO, etc.)
Containment Refractory or frozen ledge
Temperature Up to 2,000˚C
Product Pure metals or alloys

Why electrolysis for steel now?

Historically there was no major driver to revolutionize a millennia old process, but today global macrotrends enable and incentivize a better approach:
  • Techno-economics of Molten Oxide Electrolysis are now cost effective
  • Clean electrification of everything
  • Decarbonization of everything
  • Society calling for cleaner solutions
The discovery

Molten Oxide Electrolysis pairs innovations developed at the Massachusetts Institute of Technology with decades of best practice from the aluminum and steel industries.

The story of Boston Metal began at MIT. With support from NASA, the American Iron and Steel Institute, and the Deshpande Center at MIT, Professor Donald R. Sadoway’s laboratory demonstrated that molten oxide electrolysis (MOE) could reliably and efficiently produce a broad platform of metals at the laboratory-scale. To commercialize these innovations, Professor Antoine Allanore, Dr. Jim Yurko and Donald R. Sadoway founded Boston Electrometallurgical Corporation in 2012.

2013 was a seminal year for the company. In the journal Nature, Antoine Allanore, Lan Yin, and Donald R. Sadoway demonstrated that MOE could produce emissions-free steel with the publication of laboratory results using a cost-effective inert anode. In that same year, Ingo Wender was the first investor to fund the company and operations moved into offices in Woburn, Massachusetts. The first semi-industrial MOE cell was commissioned shortly thereafter in 2014.

With additional funding from the DoD Defense Logistics Agency, Department of Energy, and National Science Foundation the company, now known as Boston Metal, has continued to innovate and is now bringing the MOE technology to market for ferro-alloys, steel, and a variety of other metals.
