Sandia National Laboratories is conducting an extensive review of reports and journal publications to gather existing materials data for inclusion in the Technical Reference for Hydrogen Compatibility of Materials. Additionally, Sandia is working internationally with collaborators to acquire newly generated data for inclusion in the Technical Reference. SAND2012-7321 is an archival report issued by Sandia National Laboratories representing the reference information compiled as of September 2012. Updates and additions of individual sections of this report are available at the "Technical Reference for Hydrogen Compatibility of Materials" website linked below. The Technical Database for Hydrogen Compatibility of Materials is intended to be a complement to the Technical Reference for Hydrogen Compatibility of Materials. The database is formulated in the Granta MI framework and available at the "Hydrogen Materials Technical Database" link below and includes curated data on strength, fatigue and fracture measured in gaseous hydrogen environments. Guidance on 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. Materials property measurement is needed on deformation, fracture and fatigue of metals in environments relevant to this hydrogen economy infrastructure. The identification of hydrogen-affected material properties such as strength, fracture resistance and fatigue resistance are high priorities to ensure the safe design of load-bearing structures.
