Abstract
A hydrogen gas storage tank includes a body including a steel bulk region and a passivating metal oxide layer adjacent to the steel bulk region, the oxide layer comprising a number of metal oxide molecules, all having a morphology, wherein at least about 51 wt. % of the number of metal oxide molecules are Fe2O3 molecules having morphologies of (012), (001), and/or (110) surface facets such that the oxide layer is configured to lower hydrogen adsorption into the steel bulk region by at least 25% compared to a steel bulk region free from the passivating metal oxide layer.
