Toward the realization of hydrogen storage and transportation systems with lower cost

In preparation for the forthcoming commercialization and subsequent world-wide adoption of fuel-cell vehicles and hydrogen stations, a specialized set of components (e.g., vessels, valves, regulators and metering devices) is being developed for the handling of high-pressure hydrogen gas. It is well known that hydrogen easily penetrates into the materials and causes so-called “hydrogen embrittlement (HE)”. The degree of susceptibility of materials to HE greatly influences their possible selection and qualification for use with high-pressure hydrogen gas. We are tackling the deeper understanding of HE mechanism of various metallic materials to be used for the high-pressure hydrogen systems. The research results will contribute to the establishment of novel design guidance and reasonable regulation review, realizing the adoption of lower cost materials without sacrificing safety.
