Modelling & simulation is increasingly used as a key enabler to the effective development and delivery of hydrogen-ready material/system solutions. Leveraging the widespread availability of high-performance computing resources and emerging data-driven tools, predictive models have reached a high maturity level covering the full product lifecycle - from early design stages and material selection, through digital optimisation of the manufacturing process, to digital certification and testing and, ultimately, simulating the product performance in hydrogen service and managing its integrity in real operations.

This NAFEMS seminar aims to bring together modelling & simulation experts from academia, industry, and research & technology organisations (RTOs) to share know-how and best practices on modelling the effects of hydrogen on the structural properties and behaviour of materials and demonstrate the value of numerical modelling on practical use cases. This is a unique opportunity for experts from different sectors (e.g., metals vs. composites) to come together and discuss their industry-specific challenges and discover possible technology transfer opportunities.

Among other topics, there will be a particular focus on the areas below:

• R&D trends in modelling hydrogen transport/permeation through metals and composites.
• Advances in modelling hydrogen-material interactions and related degradation mechanisms (e.g., embrittlement and subcritical crack growth in metals, swelling and blistering in polymer composites).
• Recent developments in manufacturing process simulation of parts for hydrogen service, including (but not limited to) additive manufacturing.
• Trends in digital certification and multiscale modelling-based qualification of products for hydrogen applications.
• Developments in predictive models for lifetime prediction and fitness-for-service of assets in hydrogen service.

The shared determination by key stakeholders in the energy value chain for a clean and sustainable energy transition has never been stronger, nor has the need for cross industry working.
