The spray pipe includes a contraction section, an expansion section, and an acceleration section.

An apparatus, system, and method for temporary fluid commodity transfer stations. A fluid commodity transfer structure can include a base member, a casing, and a fluid commodity transfer system. The fluid commodity transfer system can be configured to dispense a commodity for transloading from opposite sides of the fluid commodity transfer structure. A modular fueling station system can include one or more receptacles operably coupled to a fluid commodity transfer structure to allow a fluid commodity transfer system to utilize each receptacle as a fuel reservoir. The fluid commodity transfer structure can be loaded onto an intermodal transport vehicle, unloaded at a location, deposited at the location, and be operably coupled with one or more receptacles and/or other fluid commodity transfer structures to provide fueling infrastructure for fleet vehicles or allow for the commercial transfer of fluid from one receptable to another as a mobile fluid transfer system.

The present disclosure provides mounting plates having a mounting portion adjacent to a plurality of fastening regions and a flexing portion adjacent to a mounting feature. The fastening regions can be connected to a frame system. The mounting feature can be connected to an end of a pressurized tank. The end of the pressurized tank can move relative to the frame system and the mounting plate can flex such that the flexing portion moves out of the plane of the fastening region to accommodate the motion of the end of the pressurized tank. Connection to the end of the pressurized tank can be provided at a tank collar than can be bonded or threadably connected to the mounting plate via a connection mechanism. The connection mechanism can be an expandable plug or a sleeve that connects to the tank collar.

A cryogenic nitrogen sourced gas-driven pneumatic device that is configured to provide a pressurized gas to end devices is described herein. In some instances, the a cryogenic nitrogen sourced gas-driven pneumatic device may include a cryogenic storage tank that stores liquid nitrogen under pressure, a pressure build circuit configured to build and hold pressure in the cryogenic storage tank, an economizer circuit configured to draw gas that forms in the cryogenic storage tank for an end device, and a vaporizer is configured to convert the liquid nitrogen into a gas as it is drawn through the vaporizer.

The present disclosure provides systems and methods for producing a hydrogen storage vessel that is lightweight. The hydrogen storage vessel may comprise an inner body and an outer body structured as concentric rings with a conic interface. The vessel may have four material layers, including a barrier layer, an insulation layer, a fiber knit, and an abrasion layer. The fiber knit may be braided to trap the hydrogen, as the barrier layer may not be completely impermeable. Additionally, the fiber braid may be clamped to the outer body, enabling pressure pushing on the inner body to wedge and seal the storage vessel.

The invention relates to a MEGC trailer for transportation and temporary storage of a pressurized gaseous fluid, the MEGC trailer comprising: two gas banks each comprising one or more gas sections and a fluid conduit system. The fluid conduit system comprises a first and a second bank valve between which an additional gas section is connected to the fluid conduit system. Wherein the first and second bank valves are controllable so that the volume of at least one of the two gas banks can be changed with the volume of the additional gas section.

The present disclosure provides systems and methods for storing, transporting, and using hydrogen. In some embodiments, the method may comprise (a) storing hydrogen fuel in one or more fuel storage modules; (b) transporting the one or more fuel storage modules to a vehicle fueling site, wherein one or more hydrogen fuel compatible vehicles are located at or near the vehicle fueling site; (c) loading the one or more fuel storage modules into the one or more hydrogen fuel compatible vehicles, wherein the one or more fuel storage modules are configured to be releasably coupled to the one or more hydrogen fuel compatible vehicles; and (d) decoupling the one or more fuel storage modules from the one or more hydrogen fuel compatible vehicles after the one or more fuel storage modules are depleted or partially depleted.
