This study day, organized by the Cercle d'Etudes des Métaux in partnership with Tenerrdis, is aimed at engineers and technicians preparing to use hydrogen in an industrial environment where it is not yet widely used.

This gas reacts with the materials with which it comes into contact, hence the need for a judicious choice of materials. While precautions need to be taken in its use, it also offers a unique opportunity to contribute to the decarbonization of production, particularly where public authorities are creating the infrastructures that make it available.
