Cogne, located in Aosta, has entered a new period in steel production with a green hydrogen facility.

Stainless steel producer Cogne Acciai Speciali has taken a significant step toward more sustainable steel production. As part of the “Green Hydrogen in Cogne” project, the company has commissioned a hydrogen plant in Aosta, Northern Italy.

Cogne, located in Aosta, has entered a new period in steel production with a green hydrogen facility.

With the new facility, Cogne will replace fossil natural gas with green hydrogen for the first time in its central industrial heat treatment process. This transformation is considered a critical step toward making energy-intensive industrial processes climate-neutral. According to the company’s estimates, the use of green hydrogen—produced via electrolysis from renewable sources—could prevent up to 27,300 pounds of CO₂ emissions per ton of hydrogen used.

Steel for hydrogen, hydrogen for steel
Cogne Acciai Speciali is playing a role not only in its own production but also as a material partner in the hydrogen value chain. The company’s high-performance stainless steel portfolio offers specialized solutions for valves, sensors, pipelines, and other components used to transport hydrogen.

According to Cogne, these steels have been developed to meet the highest demands in terms of corrosion and wear resistance, as well as resistance to hydrogen embrittlement. In this way, the company aims to contribute to the technological implementation of the energy transition both in Italy and internationally.
