Hertha Metals

Hertha Metals is a Conroe, Texas-based steel company working to reshore American iron and steel production. Its Flex-HER single-step process converts any grade of iron ore directly into crude steel or high-purity iron in one continuous reactor, using natural gas or hydrogen as the reductant instead of coal-dependent blast furnaces, which the company says yields production costs about 25% lower and emissions reductions of 50% with natural gas and up to 98% with hydrogen. It operates a 360-ton-per-year demonstration plant in Conroe, supplies high-purity iron to rare-earth magnet manufacturers, and is in supplier qualification with major U.S. magnet producers
