Who We Are

From a small group of visionary researchers, engineers, and metallurgists, we’ve grown to a team of over 90 professionals – and counting. The endorsement of our innovative technology and business model by a world-class investor syndicate fuels our passion to decarbonize one of the world’s largest sources of CO2 emissions. We’re transforming how metals are made.
