International Conference on Metals and Hydrogen

We are pleased to announce that OCAS and Ghent University are joining forces for the fifth edition of the International Conference on Metals and Hydrogen. SteelyHydrogen 2025 provides a unique environment to share and exchange experiences on the link between metals and the various aspects of hydrogen: hydrogen-microstructure interactions, hydrogen embrittlement, hydrogen detection, etc.

Since its first edition, the spirit of the conference has been in keeping a balance between fundamental and industrial aspects. Whereas early editions focussed mainly on steel substrates, the scope has been broadened to other metals such as Al, Ni and Ti, with revealing scientific contributions and new applications being addressed.

Given today’s interest in hydrogen as energetic vector, and the maturity of some technologies becoming reality, the SteelyHydrogen forum in 2025 will again pay specific attention to the role of hydrogen in the global energy transition. Particular focus will be on material challenges.

As such, the scientific scope of the conference can be summarised by the following topic categories:

  • Hydrogen embrittlement: effect of hydrogen on mechanical properties

    • Aqueous environment
    • Gas environment
    • HIC & Stress Sulphide Cracking (SSC)
    • Metallurgical influences
    • Mitigation actions (microstructural design, coatings, etc.)
    • Mechanisms
  • Modelling the hydrogen-metal interactions and/or the hydrogen embrittlement from atomic to meso-scale

  • Advanced methods to characterise hydrogen

  • Hydrogen-metal interactions: hydrogen activity, diffusion, trapping, etc.

  • Surfaces and coatings for metallic substrates in hydrogen environment

  • Industrial hydrogen challenges

  • Future material challenges for hydrogen applications

  • Other
