The present disclosure provides a vehicle having a storage assembly for storing and dispensing a pressurized gas. The storage assembly includes a first storage cylinder section and a second storage cylinder section that each have multiple storage cylinders arranged longitudinally parallel to one another in a first layer and at least in a second layer. The storage cylinders are fluidically connected to one another in a meandering manner by a plurality storage cylinder loops. Each of the storage cylinder loops is connected to an axial end of a storage cylinder disposed in the first layer and an axial end of a storage cylinder disposed in the second layer. The storage assembly includes a cross member frictionally connected to the body of the vehicle and arranged in an interstice defined between the first and second storage cylinder sections.

A load-decoupling attachment system is configured to secure to a primary structure. The load-decoupling attachment system includes one or more baffle tiers. One or more beams are coupled to the one or more baffle tiers. The one or more beams include a fore end and an aft end. A fore end coupling joint is configured to secure the fore end to a first portion of the primary structure. The fore end coupling joint includes a spherical bearing that allows the fore end to rotate in relation to the first portion of the primary structure. An aft end coupling joint is configured to secure the aft end to a second portion of the primary structure. The aft end coupling joint includes a slot that allows the aft end to linearly translate in relation to the second portion of the primary structure.

The invention relates to a tank for storing hydrogen by absorption into a hydrogen-storage material. The tank contains a chamber, a hydrogen feed inlet, a hydrogen discharge outlet, and an inner structure for storing the hydrogen-storage material. The inner structure contains a stack along a longitudinal axis of at least two levels for containing the storage material. Each level includes a distributor cup, a receiver cup for the storage material, and a collector cup. The distributor cups, receiver cups and collector cups are stacked one on top of the other and rigidly and sealingly connected to one another. The invention also relates to a distribution pipe distributing in parallel hydrogen in the distributor cups such that, for each level, hydrogen flows from each distributor cup to the collector cup by passing through the storage material.

A method of continuously conveying compressed gas to a plurality of vehicles, where the plurality of vehicles includes at least a first vehicle having a higher tank pressure and a second vehicle having a lower tank pressure that are simultaneously seeking compressed gas from the same delivery conduit. The method includes compressing gas using at least one compressor, conveying the compressed gas from the at least one compressor to a backpressure apparatus, conveying a non-bypass fill portion through the backpressure apparatus, diverting a bypass fill portion through a bypass conduit to at least one distributor, conveying the bypass fill portion through the at least one distributor to at least one of the one or more delivery conduits and subsequently to at least the first vehicle, and conveying the non-bypass fill portion through at least one of the one or more the delivery conduits to at least the second vehicle.

A high-pressure composite container having a gastight nozzle structure includes a metal nozzle formed at a side of an inlet of a plastic liner layer that defines an inner layer of the high-pressure composite container; a nozzle insert which is inserted into and attached to the metal nozzle in a direction from an inner side of the plastic liner layer to an outer side of the plastic liner layer; and a nut member fixed to an upper end portion of the nozzle insert.

A high-pressure compressor having a hydraulic system and a gas chamber, where the hydraulic system includes a reservoir, connected to a hydraulic fluid chamber by a hydraulic flow path and a pump assembly positioned in the hydraulic flow path, and the compressor furthermore includes a control element controlling the flow of hydraulic fluid in the hydraulic flow path and thereby the pressure in the hydraulic fluid chamber, where the control element and the pump assembly is configured for controlling the pressure of hydraulic fluid in the hydraulic fluid chamber when the compressor is not in operation.

The present disclosure relates to a thermal pressure relief device for gas pressure tanks and/or gas pressure tank systems, comprising: a valve unit which can be fluidically connected to the gas pressure tank and/or the gas pressure tank system and comprises at least one fluid path, by means of which the gas pressure tank and/or the gas pressure tank system can be drained, in particular a gas stored under high pressure in the gas pressure tank and/or the gas pressure tank system can be discharged into an environment, wherein the valve unit comprises a locking element which can be shifted and/or moved between an open position, in which the gas can flow through the fluid path, and a closed position, in which no gas can flow through the fluid path, and a first trigger means configured to shift and/or move, due to heat impact, in particular when reaching a predetermined temperature, the locking element into the open position and/or to enable the locking element to shift and/or move into the open position, wherein the first trigger means is further configured to detect the heat impact at least at one further location of the gas pressure tank and/or the gas pressure tank system, which is not the installation location of the thermal pressure relief device, and/or to detect the heat impact at least at two spatially separated locations and/or areas, in particular of the gas pressure tank and/or the gas pressure tank system.

In one example, a portable fuel gas system includes: a portable enclosure; a fuel gas supply manifold; a throttle in fluid communication with the fuel gas supply manifold. The fuel gas supply manifold includes a first pressure zone and a second pressure zone separated from one another by the throttle; and a fuel gas shutoff valve in fluid communication with the fuel gas supply manifold and operative to control a flow of a fuel gas in the fuel gas supply manifold, wherein the fuel gas supply manifold, the throttle, and the fuel gas shutoff valve are disposed within the portable enclosure.

A flowmeter failure determination method includes: a step of measuring a filling amount of hydrogen gas filled in a fuel tank of an automobile, using a flowmeter; a step of acquiring information of a pressure and a temperature of the fuel tank; a step of calculating the filling amount of the hydrogen gas filled in the fuel tank based on the acquired pressure and temperature and a capacity of the fuel tank in which an expansion rate of the fuel tank is considered; and a step of determining presence or absence of a failure of the flowmeter using an error value between the measured filling amount and the calculated filling amount.

The present invention relates to a knob cap for a high-pressure tank including a coupling groove portion corresponding to a knob of a liner of the high-pressure tank formed in a lower surface of a body; a peripheral wing portion extending outward in a lower end of an outer circumferential surface of the body to be in contact with a surface of the liner; and a thickness conversion portion formed in the outer circumferential surface of the body to change a thickness between a center line and the outer circumferential surface.
