Structural durability in the Net Zero age: Effect of degradation

Project summary

Achieving Net Zero in transport and off-road applications demands innovative solutions – and hydrogen and low-carbon intensity (LCI) fuels are at the forefront of this transition. However, these fuels introduce new challenges for material performance and structural reliability.

This project investigates how hydrogen and LCI fuels affect the degradation of surfaces and, ultimately, the structural integrity and durability of components operating in harsh environments. A key focus is understanding the critical transition from slow, progressive degradation to rapid deterioration caused by the formation of macroscopic defects.

When exposed to hydrogen and LCI fuels, metallic components experience unique chemical reactions. Combined with elevated temperatures, these interactions can alter surface and subsurface layers, transform microstructures, and introduce defects that compromise reliability.

To address these challenges, the project will combine microstructural analysis and mechanical testing with advanced techniques such as Acoustic Emission for non-destructive monitoring and Machine Learning for predictive modelling. These tools will enable the development of design strategies that prevent defect initiation and propagation, ensuring safer and more durable systems.

The outcome will be a set of insights and predictive tools that support the design and optimisation of next-generation engineering solutions for hydrogen and LCI fuel applications.

The project is based at the Caterpillar Innovation & Research Centre at Loughborough University.
