There are three types of high pressure gaseous hydrogen storage vessel, namely: stationary, vehicular, and bulk transportation.
First, recent progress toward low-cost, large capacity and light-weight on high pressure gaseous hydrogen storage vessels is reviewed.
High pressure gaseous hydrogen storage offers the simplest solution in terms of infrastructure requirements and has become the most popular and highly developed method.
Other properties, such as metal hydrogen bond strength and maximum gaseous phase storage capacity, are predominately dependent on the alloys' composition, i.e. the Mn/Ni ratio.
This chapter discusses the American Society of Mechanical Engineers (ASME) codes and standards that have been developed for pressure vessels, piping and pipelines for high pressure gaseous hydrogen storage and transport.
Cylindrical pressure vessels are the traditional option for on-board gaseous fuel storage; however they possess domed heads that are prone to over-design and a source of manufacturing difficulties.
Y increased reversibility of gaseous phase hydrogen storage.
Nd increased C14 phase abundance, decreased the plateau pressure, increased gaseous phase hydrogen storage capacities, and increased discharge capacity and bulk hydrogen diffusion.
As the Y-content increased, the gaseous phase hydrogen storage capacity measured at 30 °C decreased in the high-Cr series and increased in the high-Co series.
The influences of rare-earth element additions on the structural, gaseous phase hydrogen storage, and electrochemical properties of Laves phase-related body centered cubic (BCC) metal hydride alloys were studied using a series of alloys with the design composition of Ti14.6Zr2.1V44.1Cr12.2Mn6.9Fe2.7Co1.4Ni14.7Al0.3RE1.0, where RE (rare earth) = Y, La, Ce, Nd.
