Project summary description:
With the growing demand for green hydrogen transportation and the rise in hydrogen-natural gas blending, hydrogen gas pipelines offer a promising outlook through the conversion of existing natural gas pipelines or the manufacturing of new ones.

Both approaches require extensive material design to prevent issues such as leaks and hydrogen embrittlement. This project aims to explore the feasibility of various materials for hydrogen pipelines by studying the effects of transport properties like diffusion and permeability on material structures with the goal of identifying materials and implementation methods that will accommodate hydrogen gas transport under the desired pipeline conditions.

The project will include:

• The design and development of a small-scale hydrogen transport rig to evaluate hydrogen transport properties through various materials,
• Feasibility studies on coating materials and techniques for hydrogen barrier materials and,
• Mathematical modelling of hydrogen transport through thin film coatings.
