In New York, Chemical Engineering reported that Sarralle announced the completion of a green hydrogen combustion system at ArcelorMittal’s Olaberria plant in Spain, one of Europe’s most advanced steel production facilities.
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 vapor, making it a key enabler of zero-emission processes, according to the report.
“This project is a key step toward the future of the steel industry. It proves that green hydrogen combustion technology is already a reality and that decarbonizing industrial processes is possible,” said Itsaso Auzmendi-Murua, Head of the Hydrogen Business Line at Sarralle.
