Hydrogen, with its exceptional diffusivity and complex interaction with metallic materials, remains a major challenge for fast-changing industrial sectors. Its properties, which offer both opportunities and risks, particularly in terms of embrittlement, assisted corrosion and durability, require a detailed understanding of the mechanisms involved, and constant adaptation of the processes used.
Following on from previous editions, which took stock of damage phenomena and metrology, as well as the challenges of hydrogen production, storage and transport, the A3TS is once again bringing together the scientific and industrial community to explore these crucial issues in greater depth. Recent advances, experience feedback and technological developments will shed light on the choices to be made in the face of an accelerating hydrogen industry.
Held on October 6 and 7, 2026 at the Maison de la Mécanique in Courbevoie, the event will provide a comprehensive overview of current issues: materials behavior in hydrogen environments, process compatibility and safety, developments in characterization methods, and prospects for emerging uses. Thanks to the expertise of the speakers and the diversity of the contributions, this event aims to provide concrete answers to the questions raised by the growing integration of hydrogen into tomorrow's energy and industrial systems.
