Research Collaboration | Hydrogen-Material Interactions & Surface ChemistryPEPR H2-HYPERSTOCK Project collaboration with:• CEA (French Alternative Energies and Atomic Energy Commission)• LaSIE (Laboratoire des Sciences de l’Ingénieur pour l’Environnement), La Rochelle University – CNRS 7356• Mines de Saint-Etienne – Institut Mines Telecom, Laboratoire Georges Friedel (UMR CNRS 5307)Project Focus: Investigating hydrogen and surface oxide interactions to bridge understanding between electrochemical and gaseous hydrogen charging mechanisms.Key Contributions:• Material Performance Testing: Assessed hydrogen embrittlement risk in industrial-grade steels and alloys (e.g, L485 pipeline steel, martensitic steels, Aramco-grade iron), relevant for storage and transport applications.• Barrier Layer Evaluation: Investigated the role of surface oxides in reducing hydrogen uptake during cathodic charging, with implications for corrosion prevention and system integrity.• Advanced Surface Analysis: Utilized cutting-edge techniques to characterize hydrogen interactions and failure mechanisms- Scanning Electron Microscopy (SEM)- Scanning Kelvin Probe Force Microscopy (SKPFM)- Glow Discharge Optical Emission Spectroscopy (GDOES)- Raman Spectroscopy - X-ray Photoelectron Spectroscopy (XPS)This work supports the development of predictive models for material behavior in hydrogen environments, contributing to safer and more efficient hydrogen energy technologies.
