SARRALLE has achieved a major milestone in the path toward industrial decarbonisation with the successful completion of a pioneering green hydrogen combustion system at ArcelorMittal’s Olaberria plant.
Designed, manufactured, and installed entirely by SARRALLE, the system enables the reheating furnace in the rolling mill to operate using 100% green hydrogen instead of natural gas — fully eliminating CO₂ emissions from the combustion process.
Developed in close collaboration with Nippon Gases, the system replaces traditional air–natural gas burners with hydrogen-based oxy-fuel burners, significantly improving thermal efficiency and ensuring cleaner, more sustainable steel production. The combustion of hydrogen generates only water vapour, making it a key enabler of zero-emission processes.
This innovation represents a crucial step toward the decarbonisation of the steel sector, which currently accounts for around 9% of global CO₂ emissions.
With this achievement, SARRALLE strengthens its leadership in hydrogen-based industrial solutions, reaffirming its commitment to innovation, energy transition, and the sustainable future of the steel industry.
