Hydrogen-Induced Damage to Polymers at High Pressure: Understanding Interaction and Failure Mechanisms - HYPOLFAIL

Project summary

Green hydrogen (gH2) is essential for a sustainable energy future, but it has inherent challenges for safe storage and transport, especially with traditional materials that are prone to hydrogen embrittlement and permeability issues. This calls for advanced materials capable of withstanding extreme pressure and temperature conditions without degradation. HYPOLFAIL aims to develop optimized polymeric materials with enhanced H2 compatibility and durability, specifically focusing on elastomers and thermoplastics for sealing and high-pressure gas storage applications. Using AI-driven multiscale modeling and in-situ/ex-situ experimental testing, the project will create polymers with improved permeation resistance (10%) and extended service life (20%), pioneering a “design THE materials” approach for sustainable economy applications. The project supports a more reliable, cost-effective H2 economy, which, aligns with EU climate goals, and strengthens Europe’s position in the global H2 market.
