Green steel plant glugs out first ton of molten metal | With clean electricity, the process could make steel with zero CO2 emissions.


MIT spinout Boston Metal has powered up its electricity driven steel production reactor and made over a ton of metal in a crucial step toward commercializing its process. With clean electricity, the process could make steel with zero CO2 emissions.

“We are the only company with a direct and scalable approach to more efficient and clean steelmaking, and 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 US, demonstrating the critical innovation that can enhance domestic manufacturing.” Because the current reactor can only make about a ton or two of material per month, the company plans to build an even larger demonstration plant set to come online in 2026 and begin operations a year later.
