Who We Are

From a small group of visionary researchers, engineers, and metallurgists, we’ve grown to a team of over 170 professionals, and still counting. We’re backed by top investors and led by a world-class team of scientists and metals industry veterans as we scaleup our innovative technology to decarbonize one of the world’s largest sources of CO2 emissions — steelmaking. In 2022 we opened a subsidiary in Brazil to use our Molten Oxide Electrolysis platform to build a high-value metals business that will help miners recover value from mining waste.

  • MIT professors Donald Sadoway and Antoine Allanore demonstrated lab-scale performance of a metallic inert anode for MOE

In the early 1980s, Prof. Donald Sadoway’s MIT laboratory began research on an inert anode for aluminum manufacturing. In the late 1980s, he conceived of an electrolytic cell for the production of iron, and molten oxide electrolysis was born. Throughout the 1990s and 2000s, MOE research was extended to other metals before returning to electrolytic steelmaking and again focusing on inert anode technology.
