Transforming Metal Production

Steel has been made essentially the same way for thousands of years, by using carbon as a chemical reductant. Today, that process is responsible for about 8% of global CO2 emissions. There’s a better way.

We cracked the code to electrifying steel manufacturing

Boston Metal has developed a game-changing electrolysis process for making steel. Electrolysis is an electro-chemical process that uses direct electric current to separate chemical compounds into their constituent parts.

Our Molten Oxide Electrolysis (MOE) technology is simpler, smarter, and greener than conventional steelmaking.

In our MOE cell, an inert metallic anode is immersed in an electrolyte containing iron ore.

The result is a clean, high purity liquid metal that can be sent directly to ladle metallurgy — no reheating required.

Our MOE cell converts iron ore into liquid metal and oxygen

We’ve been building on the best practices of the aluminum and steel industries with innovations from MIT. We know our ground-breaking technology works, and now we’re scaling up at our test facility.

The Path Forward

We’re working towards the commercialization of our technology platform that will produce carbon emissions-free steel


Semi-industrial validation of MOE cell – steel production


Commercial plant deployments – ferroalloy production


Pilot plant deployment – steel production

Second half of the decade

Commercial plant deployments – steel production
