由34岁的麻省理工学院机械工程博士劳琳·梅鲁埃赫创办的赫尔塔金属公司推出了一项炼钢技术，通过单步工艺将铁矿石直接转化为精炼液钢，用天然气替代传统煤炭燃料1。该方法声称可将排放量减少至少50%，同时将成本降低25%1。
公司在德州康罗市运营的试验工厂目前日产1吨钢1。根据计划，赫尔塔金属将在2027年底前建成新工厂，年产能达到1万吨1。该公司更宏大的目标是到2030年实现50万吨的年产能1。截至2026年7月，公司已融资约2000万美元1。
Laureen Meroueh, a 34-year-old MIT mechanical engineering doctorate holder, has founded Hertha Metals to commercialize a novel steelmaking process designed to reduce both environmental impact and production costs 1. The company's single-step furnace converts iron ore directly into refined liquid steel while substituting natural gas for coal, achieving at least 50 percent lower emissions and 25 percent cost savings compared to conventional steelmaking methods 1.
Hertha Metals currently operates a pilot facility in Conroe, Texas, producing one ton of steel daily 1. The company has raised approximately $20 million in funding as of July 2026 and plans to construct a new facility capable of producing 10,000 tons annually, with operations beginning by the end of 2027 1. Looking further ahead, Hertha Metals aims to reach annual production capacity of 500,000 tons by 2030 1. Given that the United States produces roughly 80 million tons of steel annually, the company's planned output would represent a meaningful but still modest contribution to domestic steelmaking 1.
