Finnish Giant Metso Launches Frankfurt Pilot Plant for Low-Carbon Steel
Finnish engineering giant Metso has inaugurated a pioneering pilot plant in Frankfurt. The Circored plant focuses on hydrogen-based pre-reduction of iron ore, aiming to support the transition to low-carbon steel production.
The plant, launched by Metso, uses hydrogen as a reducing agent for continuous pre-reduction of iron ore. This method enables nearly CO2-neutral operation, thanks to electric heaters. The system integrates preheating, reduction, gas cleaning, and recycling systems for hydrogen and dust, allowing for validation of process parameters.
Metso is developing several concrete projects with customers and partners for various applications, including steel production and ilmenite processing. One key partner is Saudi Arabian Mining Company (Ma'aden). The resulting process data will be used in the design and planning of future commercial-scale plants. The Frankfurt plant can test various iron ore qualities, making it an ideal testing ground for diverse ore types.
Metso's Circored pilot plant in Frankfurt marks a significant step towards low-carbon steel production. By defining operating windows for different ore qualities and validating process parameters, the plant supports customers in their transition to greener steelmaking. The Finnish company continues to develop projects with partners like Ma'aden, paving the way for future commercial-scale plants.
