The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

The present disclosure provides a system for managing a pressure in an underground cryogenic liquid storage tank and a method for the same. The system includes: a storage tank, which is used for containing cryogenic liquid and is buried underground; an internal pump, which is located below a liquid level of the cryogenic liquid; an evaporator, provided with an upstream end which is in communication with a discharge end of the internal pump and a downstream end which is in communication with a head space via a vapor delivery line; a control valve, which is disposed on the vapor delivery line downstream of the evaporator; and a flow limiter, which is disposed on the vapor delivery line upstream of or downstream of the control valve. The present disclosure can realize efficient pressurization to the storage tank so as to prevent collapsing of the storage tank.

An integrated manifold system is disclosed that combines in a single, compact, unitary assembly a one-piece, machined manifold for connecting air supply cylinders with a first stage regulator and recharge port. The manifold body has at least one bottle port configured to removably receive a bottle of pressurized air, a first stage regulator chamber, a quick disconnect fitting port, an air channel in fluid communication with the at least one bottle port and the first stage regulator chamber, and an outlet channel in fluid communication with the first stage regulator chamber.

The present relates to a combined hydrogen storage-compression unit suitable for the filling of high-pressure (350 bar and beyond) hydrogen vessels. It includes a containment vessel filled with a hydrogen storage alloy, a heating system, a cooling system and a thermal management system. The same shall be connected directly to the hydrogen supply (e.g. an electrolyser) on one side and to the end consumer on the other side. Moreover, it offers the possibility for intermediate storage of at least one time the maximal quantity of hydrogen that is to be supplied at high pressure in a single step.

A boss includes a neck and a flange that extends radially outward from the neck. The neck includes a bore therethrough with a longitudinal axis. The flange includes an exterior surface, an interior surface, and a peripheral surface at a farthest extent from the longitudinal axis. The peripheral surface connects the interior surface and the exterior surface and includes, along any radius of the boss, a first circumferential ridge and a second circumferential ridge, wherein the first circumferential ridge is located closer to the exterior surface than the second circumferential ridge. In another aspect, a pressure vessel includes a boss and a liner. In yet another aspect, a method of assembling a pressure vessel is described, which includes inserting the boss through the aperture of the liner and connecting the boss and liner so that the peripheral surface of the boss mates with the perimeter surface of the liner.

A one-piece, machined manifold for connecting air supply cylinders with a first stage regulator and recharge port has at least one bottle port configured to removably receive a bottle of pressurized air, a first stage regulator chamber, a quick disconnect fitting port, an air channel in fluid communication with the at least one bottle port and the first stage regulator chamber, and an outlet channel in fluid communication with the first stage regulator chamber.

A tank support assembly for a vehicle includes a vehicle structure and a storage tank assembly. The storage tank assembly is held in place relative to the vehicle structure via a magnetic support system. The magnetic support system includes tank magnets affixed to the storage tank assembly and structure magnets affixed to the vehicle structure. The tank magnets interact with the structure magnets to passively provide repulsive magnetic forces that constrain movement of the storage tank assembly relative to the vehicle structure without the tank magnets mechanically engaging the structure magnets.

A system and method of operation is described wherein a cryogenic liquid transport fluid is used as in a thermal cascade with at least one volatile gas. The volatile gas in the liquid state enables transport thereof. In operating this system, the liquid volatile gas is maintained at a temperature below its boiling point, below its flash point, but above its freezing point.

In one embodiment, systems and methods include using a pressure relief shipping adapter to reduce the internal pressure of a container. A pressure relief shipping adapter comprises a body comprising a first portion and a second portion. The first portion comprises a first bore and a set of protrusions. The second portion comprises a second bore, wherein the second bore comprises a radial gap, wherein the radial gap comprises a uniform arc length along the length of the radial gap. A first end and a second end of the radial gap comprise a greater arc length than the radial gap. A pressure relief shipping adapter further comprises a pressure relief valve disposed at a first end of the first bore and an interlocking component comprising a first tab and a second tab, wherein the interlocking component is at least partially contained within the second bore.
