Description

This opportunity focuses on, but is not limited to, multi-scale computational modeling of the effects of hydrogen on the fracture and fatigue behavior of structural materials. Of particular interest are the hydrogen-steel interactions that result in changes in the crack initiation, fatigue crack growth, and failure behaviors of pipeline steel. Steel pipelines will be used to transport gaseous hydrogen from production sites to distribution sites to support the use of hydrogen as a clean energy carrier for fuel cell vehicles NIST in Boulder, CO is home to one of only a handful of US facilities with high-pressure gaseous hydrogen testing capabilities focused on collecting the data necessary to support the creation of the physics-based, multi-length scale, hydrogen-to-steel microstructure deformation model needed to implement safe and cost-effective pipeline solutions for hydrogen transport. Researchers applying for this project will have the opportunity to work with researchers from NIST, DOE, DOT, and elsewhere to develop models that incorporates all necessary damage mechanisms and their interactions needed to rapidly realize this promising technology. The multidisciplinary effort will rely not only on the unique hydrogen-test facility, but also the advanced characterization facilities and related expertise available at NIST including as needed, the Boulder Precision Imaging Facility (PIF), the NIST Center for Neutron Research (NCNR), and the National Synchrotron Light Source (NSLS) among others.
