Boston Metal is proud to announce a significant milestone in our work to scale steel decarbonization technology that will drive real impact.
We successfully commissioned a multi-inert anode Molten Oxide Electrolysis (MOE) industrial cell for clean steel production that is operational at our Woburn, Massachusetts facility. This accomplishment de-risks our technology and validates scalability to achieve commercial production.

“I can now say that tonnage steel is flowing from our multi-inert anode MOE cell,” said Tadeu Carneiro, CEO of Boston Metal. “With this milestone, we are taking a major step forward in making green steel a reality and we’re doing it right here in the U.S., demonstrating a critical innovation that can enhance domestic manufacturing.”
As highlighted in our press release and MIT Technology Review, this milestone is the culmination of years of research, innovation and dedication by our talented team. It is not just a technological advancement; it is a key step toward industrial decarbonization with the potential to address the 10% of global carbon emissions that are produced each year by steel manufacturing.
“This achievement is the sum of all the contributions from every member of our exceptional team,” said Guillaume Lambotte, PhD, Chief Scientist. “We have been pushing the boundaries of electrochemistry, materials science and engineering to scale-up Molten Oxide Electrolysis with Boston Metal’s inert anode, enabling the commercialization of this first of its kind technology.”
MOE is an efficient process that transforms all iron ore grades into high-quality liquid metal and the inert anode is the essential element that allows scalable production of pure molten iron without emitting any carbon. The performance of our inert anode, specifically designed to withstand the high temperatures and corrosive environment involved with iron ore electrolysis, has now been proven.
“The power of MOE technology has been unlocked to deliver the most direct and scalable approach to efficient steel decarbonization,” said Adam Rauwerdink, PhD, SVP Business Development. “We have defined a path forward for meeting the challenges of this hard-to-abate industry while creating economic growth throughout the steel value chain.”

This groundbreaking work began in a lab at MIT, and our team at Boston Metal is more committed than ever to driving further innovation and revolutionizing steel production.
