ABOUT THE PROJECT

Today, primary steelmaking relies heavily on coal as a chemical agent and energy source, while some greener steelmaking processes are more complex and dependent on particular, expensive materials such as high-grade iron ore. Hertha’s technology harnesses green hydrogen and electric arcs—enabling production from low-grade ores and smelting reduction at costs competitive to today’s primary steelmaking.

Hertha has reimagined the design of existing furnaces—incorporating new methods of both hydrogen injection and iron-ore handling to overcome the obstacles that have thus far prevented successful scaling of hydrogen-electric steelmaking. By leveraging existing steel infrastructure and scientific fundamentals, Hertha presents a scalable solution to decarbonize the integral processes of modern manufacturing.
