A mobile hydrogen delivery system for delivering a compressed stream of hydrogen at pressures up to 15000 psig. The mobile hydrogen delivery system includes a hydrogen compression system, a gaseous hydrogen storage system, and a delivery system for supplying hydrogen to end users. A mobile platform supports the hydrogen compression system, the gaseous hydrogen storage system, and the dispensing system. The mobile platform may be any platform, such as a trailer, capable of being pulled, pushed, or supported by any type of vehicle, such a truck, train, boat, tractor, etc.

Mobile hydrogen delivery system

A hydrogen gas cooled hydrogen storage element which includes a hydrogen storage alloy material in which hydrogen flow channels are provided. The flow channels provide pathways through the hydrogen storage material to allow for high speed hydrogen gas flow. A portion of the high speed hydrogen flow is stored within the storage material which releases its heat of hydride formation. The remainder of the hydrogen flows through the hydrogen storage material at a sufficient mass flow rate to remove the heat of hydride formation. The unit also includes an encapsulant to prevent any loose particles of the storage material from becoming entrained in the high flow rate hydrogen.

Hydrogen cooled hydride storage unit incorporating porous encapsulant material to prevent alloy entrainment

A magnesium hydrogen storage alloy that has been hydrided and compacted into highly dense pellets for shipment and use, a method for making said magnesium alloy and a method for the safe, economical shipment of said hydrided magnesium hydrogen storage material.

Safe, ecomomical transport of hydrogen in pelletized form

A hydrogen storage unit which uses hydrogen storage alloys to store hydrogen, and more particularly a heat transfer management/compartmentalization system for use in such system. The hydrogen storage alloy may be divided into compartments, separated by discs, further divided into sub-compartments by a flapper wheel. The discs and flapper wheel provide for optimal heat transfer throughout the system. The compartmentalization of the vessel may prevent compaction of the hydrogen storage alloys, which could lead to excessive strain on the vessel causing damage, deformation, or rupture of the vessel.

A hydrogen gas cooled hydrogen storage element which includes a hydrogen storage alloy material in which hydrogen flow channels are provided. The flow channels provide pathways through the hydrogen storage material to allow for high speed hydrogen gas flow. A portion of the high speed hydrogen flow is stored within the storage material which releases its heat of hydride formation. The remainder of the hydrogen flows through the hydrogen storage material at a sufficient mass flow rate to remove the heat of hydride formation.

Hydrogen cooled hydride storage unit

A mechanically alloyed hydrogen storage material having 75-95 atomic percent Mg, 5-15 atomic percent Ni, 0.5-6 atomic percent Mo, and at least one additional element selected from the group consisting of Al, C, Ca, Ce, Co, Cr, Cu, Dy, Fe, La, Mn, Nd, Si, Ti, V, and Zr, preferably between 1-15 atomic %. The mechanically alloyed hydrogen storage preferably contains from 3-15 atomic % C and at least one other element selected from the group consisting of Al, Ca, Ce, Cu, Dy, Fe, La, Mn, and Nd. The hydrogen storage materials are created by mechanical alloying in a milling apparatus under an inert atmosphere, such as argon, or a mixed atmosphere, such as argon and hydrogen. The speed and length of the milling are varied.

A self-heating metal-hydride hydrogen storage system comprising: a primary metal-hydride storage container housing a metal-hydride hydrogen storage material, the primary storage container having a hydrogen outlet port; a hydrogen combustor housed within the primary metal-hydride storage container and surrounded by the high-temperature storage material, the combustor having a hydrogen inlet port gaseously connected to the hydrogen outlet port of the primary storage container; and means for supplying hydrogen gaseously connected to the hydrogen inlet port of the combustor.

Self-heating metal-hydride hydrogen storage system

A metal hydride hydrogen storage system comprising: at least a first metal hydride storage module directly coupled to an identical second metal hydride storage module, where each of the storage modules comprises: a metal hydride pressure vessel having a first and a second valved port; and a metal hydride material disposed within the pressure vessel; where the second valved port of the first module is directly coupled to the first valved port of said second module. The first and second valved ports of each of the storage modules may be adapted so that they are normally closed and so that said second valved port of the first module and the first valved port of the second module are urged open upon direct coupling.
