Hydrogen 2026: Technological challenges and sustainability of metallic materials
In response to the growth of the hydrogen sector , A3TS is organizing a meeting dedicated to the technological challenges of metallic materials on October 7th and 8th, 2026. Join academic and industrial experts to explore the mechanisms of durability and embrittlement, as well as innovations in heat and surface treatments, to ensure the success of your technological choices.
Why participate in the Hydrogen 2026 event?
You will participate in:
2 days of technical discussions with experts in the field
25 scientific and technological conferences
A poster area
The development of hydrogen as an energy carrier (heavy-duty mobility, industrial decarbonization) places unprecedented demands on materials. This event is the essential hub for:
Understanding hydrogen embrittlement mechanisms (HEM).
Discover new barrier coating and thin film solutions.
Optimize implementation and heat treatment processes in a hydrogen atmosphere.
The program's key themes
We are seeking contributions focusing on the following areas:
➤ Damage and weakening of metals
‧ Behavior of metallic materials in the presence of hydrogen:Steels, nickel alloys, titanium, aluminum.
‧ Risks related to manufacturing processes:Embrittlement during processing, welding, casting, or after surface treatments.
‧ Decision support:Guides for selecting materials, mechanical strength, corrosion, and stress corrosion cracking (SCC).
➤ Infrastructure: Hydrogen storage, transport, and uses
Protective solutions:Barrier coatings, preventive thermal and mechanical treatments.
‧ Compatibility:Analysis of specific constraints on high-pressure transport and storage networks.
‧ Lifecycle management:Predictive maintenance and long-term durability of existing infrastructure.
➤ Electrolyzers/Fuel cells: surface functionalization
‧ Production:Development of materials for electrolyzers (bipolar plates, porous layers).
‧ Specific corrosion:Impact of electrolytes and durability of generation components.
‧ Combustion:Effects of direct hydrogen combustion on walls and test benches.
➤ Metrology and integrity control
‧ Dosage and Localization:Techniques for measuring hydrogen in materials and monitoring under hydrogen atmospheres.
‧ Standardization:Changes in standards and certification issues.
‧ Monitoring:Non-destructive testing (NDT) methods for monitoring equipment in service.
➤ Poster session
Oral presentations will each have a 25-minute slot:
The conferences will primarily be in French, but some may be given in English. To facilitate participation by non-French speakers, we recommend that French speakers use English slides.
A POSTER area will be set up between the conference room and the break area.
