Technological Support for Evaluation of Hydrogen Compatibility of Materials in Laboratory Conditions

Materials selection for hydrogen service is needed to support the deployment of hydrogen as a fuel as well as the development of codes and standards for stationary hydrogen use, hydrogen vehicles, refueling stations, and hydrogen transportation. Hydrogen energy infrastructure is currently in the process of development and in preparation for mass transportation of hydrogen gas and methane-hydrogen media involves significant use of the existing network of gas pipelines and formation of a network of hydrogen pipelines. Materials property measurement is needed on deformation, fracture and fatigue in hydrogen-containing media. Determination of steel properties such as strength, crack and fatigue resistance are priority to ensure safe design of pipelines transporting hydrogen gas or methane-hydrogen mixture. At the same time, there is a problem in technological support for evaluation of hydrogen compatibility of materials in laboratory conditions for evaluation of hydrogen embrittlement, depending on hydrogen concentration, methods and modes of loading, temperature, pressure and actual properties of materials.
