In India, BioEnergy Times reported that steelmaking company ArcelorMittal has successfully started using a system that runs entirely on green hydrogen to heat its rolling mill in Olaberria, Spain.
The mill requires intense heat to prepare steel for shaping. The company has swapped out its previous natural gas furnaces for new units that burn only green hydrogen. This new system was designed and installed by the Spanish engineering firm Sarralle, according to the report.
This project represents a practical step in using hydrogen to clean up industrial processes. However, ArcelorMittal has recently been hesitant to use hydrogen for the larger, more complex job of primary iron production in Germany, citing high costs, the report added.
