According to the invention, the storage housing (2) or the compresses gas storage unit (1) is surrounded by a heat protection shield (5) at least in regions, preferably releasing the at least one overload valve (4). The invention also relates to a vehicle comprising a compressed gas storage unit (1) according to the invention for storing hydrogen.

A hydrogen storage system includes a hydrogen storage alloy containment vessel comprising an external pressure containment vessel and a thermally conductive compartmentalization network disposed within the pressure containment vessel. The compartmentalization network creates compartments within the pressure vessel within which a hydrogen storage alloy is disposed. The compartmentalization network includes a plurality of thermally conductive elongate tubes positioned within the pressure vessel forming a coherent, tightly packed tube bundle providing a thermally conductive network between the hydrogen storage alloy and the pressure vessel. The hydrogen storage alloy is a non-pyrophoric AB.sub.2-type Laves phase hydrogen storage alloy having: an A-site to B-site elemental ratio of not more than 0.5; and an alloy composition including (in at %): Zr: 2.0-5.5, Ti: 27-31.3, V: 8.3-9.9, Cr: 20.6-30.5, Mn: 25.4-33.0, Fe: 1.0-5.9, Al: 0.1-0.4, and/or Ni: 0.0-4.0.

Tank for storing liquefied gas comprising a sealed housing defining a storage space for the liquefied gas, the housing comprising a lower end and an upper end, the tank comprising a device for measuring the level of liquid in the housing, the device for measuring the level of liquid comprising, arranged in the housing, a float and a guide for moving the float, characterized in that the guide comprises an end connected to an upper portion of the housing and a lower end connected to a lower portion of the housing, the float being mounted moveably in translation on the guide such that the float is free to slide along the guide, the device for measuring the level of liquid further comprising at least one float position sensor.

Protective devices for pressurized gas cylinders have a housing which is arranged around an inner cavity intended for receiving an extraction valve and which has access openings for the extraction connection and for further fittings. In order to counteract soiling or contamination of the extraction connection, the invention provides for an elastically deformable safety element to be fastened to the housing in the region of the access opening of the extraction connection, said element being able to be swung out from a closed position, in which the extraction connection is completely covered and/or enclosed by the safety element, into a position in which it frees the extraction connection.

A pressure vessel disclosed herein comprises a chamber. The pressure vessel also comprises a passageway extending from an exterior wall of the pressure vessel to the chamber. A one-way valve is disposed in the passageway. The one-way valve is normally closed and is in fluid communication with the chamber. A plug is disposed within the passageway and is accessible from outside of the pressure vessel.

A system for powering a vehicle is provided. The system can include an engine or power generation system to be powered by a fuel and a housing. The housing can be configured to couple to one or more frame rails of the vehicle, receive and protect a cylinder configured to store the fuel to be used by the engine or power generation system. The housing can have one or more access panels allowing access to an interior of the housing. The cylinder can include a first end portion, a second end portion, a central body forming an enclosed cavity for storing pressurized gas, a reinforcement structure disposed over the central body, and a metal foil interposed between the reinforcement structure and central body. The metal foil can be configured to reduce permeation of contents of the cylinder.

A multiple component system consisting of segments that connect to a high-pressure canister, forming a compact pneumatic delivery system. A typical cylinder capable of storing high pressure air is utilized for construction pneumatic tool operation. By connecting the tool to a two-stage regulator using a custom fitted air hose, normal low-pressure operation of construction pneumatic tools can accomplish. The air regulation system is adjustable for output pressure making it compatible with a wide range of construction pneumatic tools. The entire pneumatic delivery system is compact and offers untethered mobility, fitting all components on the user's belt.

The disclosure describes a pressure vessel having a first end with a first boss and a cylindrical portion. The vessel includes a liner, a composite shell disposed over the liner, and a first longitudinal vent disposed between the liner and the composite shell. The first longitudinal vent includes an elongated vent defining element and extends at least from the cylindrical portion of the vessel to the first boss.
