Project summary description:
With the growing need for green hydrogen transportation and the increase in hydrogen natural gas blending, hydrogen gas pipelines provide an outlook by converting existing natural gas pipelines or manufacturing new pipelines. Both solutions 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 effect of transport properties like diffusion and permeability on material structures, identifying materials and implementation methods that will accommodate hydrogen gas transport for the desired pipeline conditions.
To achieve the objectives of these research, the project will focus on measuring hydrogen permeability through a variety of materials at conditions relevant to pure hydrogen transport (at ambient temperature and high pressure < 120 bar). The performance of these materials will be then correlated with the hydrogen absorption properties and distribution by microstructural analysis of tested materials.
