Boston Metal
Boston Metal is an Advanced Metals & Metallurgy company founded in 2013 and based in Woburn, United States. It has raised $500M in total funding, most recently a Growth (critical metals) in 2026.
Boston Metal grew out of MIT research by professors Donald Sadoway and Antoine Allanore and was incorporated in 2013 (originally Boston Electrometallurgical Corporation) in Woburn, Massachusetts. Its molten oxide electrolysis (MOE) process uses electricity instead of coal to convert iron ore directly into liquid metal, eliminating CO2 from steelmaking, while a parallel MOE platform recovers critical metals such as vanadium, nickel and chromium from diverse feedstocks. The company has raised over $500 million from investors including ArcelorMittal, BHP, Microsoft's Climate Innovation Fund and Tata Steel, and operates a wholly owned subsidiary in Brazil.
MOE is one of the most advanced electrochemical routes to fossil-free steel and onshored critical metals, two pillars of industrial decarbonization and supply-chain security.
