In Bergamo, Italy, a significant trial has been initiated to utilize hydrogen in steel processing operations. This project, hosted at Tenaris' Dalmine mill in collaboration with Snam and Tenova, aims to implement hydrogen produced on-site to power burners in a reheating furnace for hot rolling seamless pipes. Snam will establish an alkaline electrolyser system to generate hydrogen, while Tenaris will introduce a 100% hydrogen-ready burner with the support of Tenova. The primary objectives of this six-month trial include developing safety guidelines, management protocols, and expertise for integrating hydrogen into industrial processes. By doing so, Tenaris strives to achieve a 30% reduction in its carbon footprint by 2030. This initiative builds upon previous plans announced in 2021 to decarbonize the Dalmine mill using green hydrogen. The broader context showcases the increasing significance of hydrogen in driving the decarbonization of steel production worldwide.
