Important results from the project
The project met its objectives by generating new knowledge into how metals behave in pressurized hydrogen and by developing and applying test methods for materials in direct hydrogen contact. It produced six technical reports and a material‑selection guideline. The project also delivered added value, including deeper understanding of hydrogen embrittlement, broad dissemination through publications and conferences, and the launch of several new research and innovation initiatives.
Expected long term effects
The project is expected to create long‑term effects by improving material selection and safety in hydrogen applications, strengthening understanding of hydrogen embrittlement, and advancing standardized test methods. Its results will accelerate the adoption of hydrogen technologies, enhance industrial competence, and stimulate new research and innovation initiatives.
Approach and implementation
The project was carried out as planned through seven work packages covering material delivery, sample preparation, hydrogen testing with the hollow specimen method, post‑analysis and reporting. Activities were appropriate and aligned with objectives, and the work progressed as intended. Collaboration within the consortium functioned well, and the timeline was followed without major deviations.
