Hertha Metals Unveils Low-Cost, Low-Emission Steel Technology; Texas Plant Groundbreaking Set for July

Unlike traditional methods, it can utilize iron ore of any grade without requiring sintering or pelletizing, significantly improving resource efficiency.

SEATTLE (Scrap Monster): Hertha Metals, a U.S.-based sustainable steel startup, has unveiled a breakthrough technology aimed at replacing conventional coal-based steelmaking, as momentum builds for expanding domestic steel capacity. The company is preparing to break ground in July on a 10,000 metric ton-per-year facility adjacent to its pilot plant in Texas, with operations expected by late next year.

The company’s proprietary process enables single-step production of steel or high-purity iron within a continuously charged furnace. Unlike traditional methods, it can utilize iron ore of any grade without requiring sintering or pelletizing, significantly improving resource efficiency.

According to Meroueh, the technology delivers steel at over 20% lower cost while reducing emissions by 50%, offering a compelling alternative in an industry under pressure to decarbonize. She emphasized that cost competitiveness is critical for market adoption, noting that Hertha aims to achieve a “negative green premium.”

Speaking at the CERAWeek by S&P Global conference in Houston, Meroueh highlighted the role of tariffs in safeguarding domestic producers from below-cost imports, particularly from China. She also stressed the need for stronger policy support, including funding and financing mechanisms, to scale innovative steelmaking technologies.
