About Symposium 2026

RISE, the French Corrosion Institute, SINTEF, KTH Royal Institute of Technology, and the University of Galway are organizing the European Symposium on Durability Issues in Low-Temperature Water Electrolysis (a Marcus Wallenberg Symposium), to be held in Stockholm, Sweden, on October 13–15, 2026.

The symposium aims to provide a dedicated forum for exchange and discussion among academia, research institutes, and industry active in the field of water electrolysis.

Scope - Abstract

Contributions are welcome in the form of oral presentations and poster sessions. Early-career researchers (PhD candidates and postdoctoral researchers) are strongly encouraged to participate.

The scientific program will cover, but is not limited to, the following topics:

  • Technologies: alkaline, PEM, AEM, membrane-less, seawater, low-grade water electrolysis as well as photo-electrochemical water splitting.
  • Degradation and durability of components: catalysts, electrolyte membranes, porous transport layers, bipolar plates, water feed pipes, and other balance-of-plant and stack components…
  • Degradation modes affecting electrolysis performance: corrosion, hydrogen embrittlement, electrolyte membrane thinning, catalyst coarsening or dissolution, and impurities in the water feed…
  • Durability solutions: anti-corrosion coatings, surface treatments, catalyst dissolution mitigation…
  • Fundamental aspects of degradation mechanisms: electrochemical degradation mechanisms and kinetics, multiscale numerical modeling…
  • Methods to investigate degradation and durability: in operando, in situ, and ex situ techniques, as well as accelerated stress tests…
  • Durability of materials for next-generation water electrolysis: PFAS-free electrolyte membranes, non-critical raw materials, and non-platinum group materials…
  • Life-cycle and techno-economic analyses: benefits of reducing critical raw materials and the potential for recycling…

The abstract can be submitted via symposium2026@ri.se.
The deadline for submission is April 30.
You will receive an acceptance notification by May 20 at the latest.
