The company tested the use of hydrogen instead of natural gas in the ladle heating process, one of the critical stages in the steel production chain.
At Sidenor’s steel plant in Basauri, the conventional burner system was replaced with a hydrogen-fueled oxy-combustion burner. The trials confirmed that the system was able to reach the required high operating temperatures, allowing the ladle heating cycle to be completed in full.
These tests are considered a significant milestone, as they demonstrate the feasibility of green hydrogen in thermal processes that are difficult to electrify due to high temperature requirements. Conducted within the framework of the IS2H4C project, the trials technically proved that natural gas can be substituted with hydrogen at this stage.
Sidenor emphasized that it continues to pursue research and investments aimed at decarbonizing its production processes in line with its sustainability objectives and reducing environmental impact. The company plans to further advance its efforts to enable the broader use of green hydrogen in steel production in the future.
