Sarralle, a Spanish industrial engineering company, has completed a green hydrogen combustion system installation project at ArcelorMittal's Olaberria steel plant in Spain.

Developed in collaboration with Japanese company Nippon Gases, the system replaces traditional air-to-natural gas burners with hydrogen-fueled oxygen burners. Combining pure oxygen and recycled hydrogen as fuel, this system improves thermal efficiency and produces cleaner exhaust gases, with water vapor being the only byproduct.

In the steelmaking process, Sarralle uses green hydrogen to replace traditional fossil fuels, which can significantly reduce carbon emissions from steel production.

This project not only proves that hydrogen-based combustion technology is feasible for industrial applications but also represents a key milestone towards decarbonization.
