Boston Metals raises $75 million to scale Molten Oxide Electrolysis platform
Boston Metal says it has raised $75 million to accelerate the deployment of its Molten Oxide Electrolysis (MOE) platform and scale production of critical metals in the US and globally. The new capital brings the company’s total funding raised to over $500 million.
The funding will enable Boston Metal to expand its critical metals business through additional commercial-scale deployments for metals such as niobium, tantalum, vanadium and nickel. MOE’s selectivity it says unlocks resources from low-grade materials, offering a new pathway to strengthen supply chains for materials essential to electrification, advanced manufacturing, AI, and defence.
Tata Steel Ltd joined the round, along with existing investors, Boston Metal says “signalling strong industrial and investor demand for novel approaches to critical metals production.”
It argues that demand for critical metals is surging across electrification, advanced electronics, infrastructure development and defence, while supply remains constrained by geopolitics and environmentally intensive extraction. Boston Metal believes that its MOE platform directly addresses this market demand by enabling efficient recovery of high-value metals from a wide range of metallurgical and industrial waste streams; and boosting yields and lowering capital costs to create new commercialisation opportunities for low-grade mineral projects.
“Critical metals are the new strategic commodities,” said Tadeu Carneiro, CEO of Boston Metal. “MOE is creating a scalable and cost-effective pathway to recover critical, high-value metals, support industrial onshoring and strengthen the secure supply of critical materials needed for advanced technologies, manufacturing and AI.”
