波士顿金属押注熔融氧化物电解规模化：1吨反应堆运行，巴西工厂

做的是什么生意

Boston Metal commercializes molten oxide electrolysis (MOE), an electric process that converts iron ore into molten iron and recovers metals like niobium from mining waste, emitting oxygen instead of CO2.

启动资金：US$262M Series C total (initial round led by ArcelorMittal, closed September 2023) plus a US$51M convertible note announced 2025-07-15.

起因

MOE was developed at MIT, and Boston Metal was founded in 2013 to commercialize it. For a decade the company moved from lab-scale reactors roughly the size of a coffee cup toward industrial scale, working on the hardest problem: inert anodes that degrade under the wrong conditions. A $262M Series C closed in September 2023 funded first-of-a-kind facilities in Boston and southeastern Brazil.

经过

In January 2025 Boston Metal started up its industrial steelmaking reactor for the first time, and on February 17 it tapped out roughly a ton of material — a milestone MIT Technology Review called proof the process can scale. In July 2025 the company raised $51M more and pushed its first commercial plant in Minas Gerais, Brazil toward full scale, using MOE to recover niobium from mining waste while steel reactors keep scaling.

结果

Live and scaling: the first commercial MOE plant in Brazil is coming online, the industrial steel reactor milestone is passed, and a larger steel demonstration plant is planned to come online in late 2026 with operations beginning in 2027.
