The round was led by Breakthrough Energy Ventures with participation from Prelude Ventures and The Engine. This funding accelerates the first industrial-scale deployments of Boston Metal's molten oxide electrolysis (MOE) technology for the production of ferroalloys. The new funding also supports the continued scale-up of MOE for the production of emissions-free steel.

"We are excited to enter this next phase in Boston Metal's development with investors that share our vision of tackling the globe's most important challenges. Molten oxide electrolysis is a platform technology that can produce a wide array of metals and alloys, but our first industrial deployments will target the ferroalloys on the path to our ultimate goal of steel. Boston Metal's MOE technology will offer the steel industry a modular, low-cost, and zero-emissions solution for the production of high tonnage steel," said Tadeu Carneiro, CEO of Boston Metal. "Steel is and will remain one of the staples of modern society, but the production of steel today produces over two gigatons of CO2. The same fundamental method for producing steel has been used for millennia, but Boston Metal is breaking that paradigm by replacing coal with electrons."

Boston Metal's molten oxide electrolysis process uses electricity to transform metals from their raw oxide form into molten metal products. The MOE process was invented at the lab-scale at MIT and Boston Metal has since scaled the technology over 1,000x. At the heart of the MOE cell is a soup of molten oxides tailored for a specific feedstock and product. Electrons act to melt this soup and selectively reduce the targeted oxide. The resulting metal pools at the bottom of the cell and is tapped by drilling into the cell in a process adapted from the blast furnace. The tap hole is then plugged and the process continues. The inherent modularity of these MOE cells provides the metal industry with a capital-efficient means of adding production capacity.

"Steel manufacturing is one of the largest single industrial emitters of greenhouse gases in the world, contributing roughly eight percent of total GHG emissions. With its unique molten oxide electrolysis technology, Boston Metal has the potential to decarbonize the massive steel manufacturing industry, and economically deliver a set of high-quality products on a global scale," said Carmichael Roberts of Breakthrough Energy Ventures. "The company is poised to create significant value with an unrivaled environmental impact in the metallurgy space. BEV is fully behind Tadeu and the Boston Metal team."

"Boston Metal has developed a platform solution that will have far reaching impacts across the metal industry," said Mark Cupta of Prelude Ventures. "They capitalize on the modularity of that technology solution with a business model that allows them to rapidly expand their impact from the ferroalloys to steel and beyond. We are excited to join BEV and The Engine in supporting the global vision of the Boston Metal team."

"Clean energy is one of the thorniest Tough Tech challenges of the century. A critical piece to achieving a carbon-free world is the decarbonization of steel production," said Katie Rae, managing partner and CEO of The Engine. "Boston Metal has spent years developing its groundbreaking technology and is incredibly close to bringing it to market. We feel privileged to help them take those next meaningful steps in bringing us closer to a zero emission future."

The Boston Metal team operates a fleet of semi-industrial MOE systems at their headquarters outside of Boston and will be commissioning its first industrial systems at this same facility. Boston Metal works closely with customers and partners to tailor the MOE platform for their specific feedstocks and products.

About Boston Metal

Boston Metal is a provider of industrial-scale, metals production solutions utilizing its Molten Oxide Electrolysis (MOE) process. MOE provides the metals industry with a more efficient, lower cost, and greener solution for the production of a wide array of metals and alloys from a wide variety of feedstocks. Boston Metal was spun-out of MIT in 2012 with an investment from Ingo Wender and has since scaled the technology 1,000x and produced thousands of kilograms of metal. Boston Metal's headquarters and industrial development center are located in Woburn, MA.
