Technical Reference for Hydrogen Compatibility of Materials

KIA FCEV SUNRISE MG 7955 6 7.jpg
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.


To support the needs of the hydrogen community, 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<hyperlink> 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 http://www.sandia.gov/matlsTechRef .


Technical Database for Hydrogen Compatibility of Materials

The Technical Database for Hydrogen Compatibility of Materials is intended to be a complement to the Technical Reference for Hydrogen Compatibility of Materials. Although still in the development stage, the Technical Database will provide a repository of technical data measured in hydrogen and is meant to be an engineering tool to aid the selection of materials for use in hydrogen.


The structure of the Technical Database will mirror the Technical Reference, using the same designations and classifications of materials. Below are some examples of the database information that is being compiled in the form of spreadsheets. A single material from a single study is represented in each spreadsheet: the material is indicated by the first four digits; the author and year are represented by the following characters; and the type of data follows (i.e. tensile, fracture and/or fatigue).
