Overview
Hertha Metals is a Texas-based industrial technology company developing the Hertha Chalyx electric-smelting process for producing high-purity iron and steel from varied ore and reductant inputs. It is scaling from a 360-tonne-per-year demonstration unit toward a planned 10,000-tonne-per-year commercial plant.
Why Hertha Metals is interesting
Hertha pairs a first-of-a-kind industrial decarbonization process with an unusually large Series A that includes a $65 million U.S. government equity investment, creating both strategic validation and meaningful execution risk.
