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 system to maintain an inert ullage in a hydrocarbon tank. The system provides for outgassing/venting of ullage gases when a high-pressure event is found within the tank. Further, when a low-pressure event occurs, during fuel discharge or based on ambient conditions, a source of inert gas, such as nitrogen) supplies gas on-demand to the hydrocarbon tank via a pressure regulator (preferably along the venting system) to maintain both the pressure and inerting of the ullage. A method for maintaining the inert ullage is also provided, whereby a low-pressure event triggers a supply of inert gas into the tank.

Disclosed are gas cylinder assemblies for containing pressurized gas. The gas cylinder assembly has a polymeric liner and a low-permeability barrier layer. The polymeric liner a first end portion, a second end portion and a central body. The central body comprises an outer surface and an inner surface disposed between the first end and the second end. The gas cylinder assembly comprises a reinforcement structure wound over the central body. The gas cylinder assembly further comprises a metal foil interposed between the reinforcement structure and central body. The metal foil is configured to reduce permeation of contents of the polymeric liner.

A General-Purpose Multimodal Transportation Container (GPMTC) for transportation and storage of hazardous cargoes is fitted with a reservoir (1), a level sensor (5) installed downright and passing through the vertical centerline and the horizontal centerline of the reservoir (1) and with a pressure sensor (6), a liquid phase density sensor (8), a vapor phase density sensor (9), a temperature sensor (7) and a set unit (10) of gyros and the accelerometers. The said group of sensors (5-9) is used to measure such main physical parameters as the pressure, the density of the liquid phase, the density of the vapor phase, the temperature of the liquid and vapor phases at several points, the level of separation of the liquid and vapor phases, the displacement vector, and misalignment of the GPMTC's base with the horizontal plane. This data is necessary for a Central System Unit (11) to calculate the volume and mass of the liquid and vapor phases and the total mass of cargo. These sensors and telemetry equipment are triggered when the circuit is closed and opened at the moment of opening and closing of the GPMTC's shut-off valves and provide measurement data which allow in real time and anywhere in the world carry out metering and calculate the mass of gas, taking into consideration the vapor phase, at the beginning and end of the cargo operations with accuracy meeting the requirements of commercial metering. Also, this GPMTC is fitted with GPS devices with telemetry equipment based on the IRIDIUM system and antenna (12) and GSM networks to determine the location of the GPMTC at any time, with an interface for geographical data transfer, including actual and measured speed and direction.

A composite gas storage tank includes a composite wall defining a main storage volume and a hollow conduit portion communicating with and extending away from the main storage volume. A hollow coupling element has a length portion which is partially embedded within and extends substantially parallel to the hollow conduit portion of the composite wall. The hollow conduit portion and the coupling element provide communication between the main storage volume and the tank exterior. A leakage path around the hollow coupling element is significantly longer than those of tanks of the prior art and reduces the rate at which hydrogen leaks from the tank. A carbon fibre filament winding extends over the length of the hollow conduit portion and provides a radially inwardly-directed force biasing the carbon fibre material of the hollow conduit portion into contact with the coupling element, further reducing the leakage rate on the leakage path.

A method of processing biogas that includes obtaining a mobile tank containing biogas at a pressure greater than 1000 psig, connecting the mobile tank to a pressure let down system, and depressurizing the mobile tank to remove biogas therein. The depressurization includes removing gas from the mobile tank using the pressure let down system, and introducing a warming gas into the mobile tank.

An anti-fire safety system for a transport vehicle has one or more storage tanks storing hydrogen. The system includes a first hydrogen-releasing system, which is configured to release outside the vehicle hydrogen contained in at least one of the storage tanks. The system also includes a second release system, which is arranged to intervene and bypass the first hydrogen release system under predetermined operative conditions. The second release system is configured to transform by a chemical reaction, at least a part of the bypassed hydrogen flowing outward from at least one storage tank, into at least one different substance.

A vehicle (100, 200, 300, 400) includes a chassis (110, 210, 310, 410), a gas storage tank (120, 220, 320, 420) for a gas, and a gas storage tank (120, 220, 320, 420) arranged between the chassis (110, 210, 310, 410) and the gas storage tank (120, 220, 320, 420) and connected to the chassis (110, 210, 310, 410) and the gas storage tank (120, 220, 320, 420), the first weighing device (140, 240, 340, 440) being arranged to measure a force exerted by the gas storage tank (120, 220, 320, 420) on the first weighing device (140, 240, 340, 440).
