en.Wedoany.com Reported - Boston Metal has completed a $75 million funding round to accelerate the commercial deployment of its Molten Oxide Electrolysis (MOE) platform and expand the production scale of critical metals in the U.S. and globally. Tata Steel Ltd. participated in this round alongside existing investors, bringing the company's total cumulative funding to over $500 million. The company is headquartered in Woburn, Massachusetts.
The company describes its patented MOE technology as an electrified platform capable of processing a variety of metal oxides to produce metals from different feedstocks. MOE's selectivity enables resource extraction from low-grade materials, providing a pathway to strengthen supply chains for critical materials needed for electrification, advanced manufacturing, artificial intelligence, and defense.
This funding will support the company in expanding its business in critical metals such as niobium, tantalum, vanadium, and nickel through additional commercial-scale deployments. Boston Metal stated that in critical metal applications, the electrolysis process can selectively recover strategic metals from low-grade materials in mining and industrial waste streams.
"Recovering critical, high-value metals from mining waste and industrial slags using the MOE electrolyzer is more efficient and cost-effective than existing methods for producing these materials," the company wrote in a fact sheet on its website. "By reducing the need for new extraction and better utilizing existing resources, MOE also supports more sustainable, lower-emission metal production."
The technology can also be used for steelmaking. Boston Metal says MOE uses electricity to convert various grades of iron ore into steel in an energy-efficient, single-step process, offering a pathway to cleaner steel production as the technology advances. Founded in 2013, the company established its Critical Metals subsidiary in Brazil in 2022. Its modular electrolyzers are scalable to meet capacity targets and require no process water, hazardous chemicals, or rare metal catalysts.
Boston Metal is a portfolio company of Climate Investment, which has offices in Houston and London. Rick Cutright, Technology Director at Climate Investment, said Boston Metal's metallurgical platform has proven its ability to produce high-quality metals from complex feedstocks, and this investment allows the company to focus on commercial production. "Critical metals are the optimal first market due to urgent demand and attractive economics, and MOE can expand supply from materials left behind by traditional processes." Climate Investment focuses on investing in underinvested, high-emission sectors with untapped potential for impact and returns.
Boston Metal states that its MOE platform creates new commercialization opportunities for low-grade mineral projects by recovering high-value metals from various metallurgical and industrial material streams, increasing yields and lowering capital costs. "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, supporting industrial reshoring and strengthening the reliable supply of critical materials needed for advanced technology, manufacturing, and artificial intelligence."
"The world needs not only more metals but also smarter, more adaptable ways to produce them," said Mark Cupta, Managing Director at Prelude Ventures. "MOE stands out for its flexibility, operating as a true platform technology with high selectivity across multiple metal systems. The Boston Metal team has developed a differentiated technology and is now leveraging it to unlock a new generation of critical metal assets."
