A gaseous fuel storage system for a vehicle is disclosed. The fuel storage system can be installed as a modular unit in the vehicle. The fuel storage system is pivotable relative to the vehicle to allow easy accessibility to the storage tanks without requiring the storage tanks to be unmounted from the vehicle. The fuel storage system also provides protection for the storage tanks through the use of shielding and energy absorbing material.

The invention relates to a re-configured valve design to accommodate a high volume of product in the delivery system and the dispensation of product upon the application of a predetermined vacuum condition on the downstream side of the valve.

Methods, apparatuses and systems directed to clathrate hydrate modular storage, applications and utilization processes. In one implementation, the present invention provides a method of creating scalable, easily deployable storage of natural gas and thermal energy by assembling an array of interconnecting, modular gas clathrate hydrate storage units.

A diagnostic method for a gas supply system includes: determining a desired ramp rate for filling a vessel from a supply of compressed gas; monitoring the actual pressure of gas entering the vessel; and discontinuing the flow of gas into the vessel when the actual pressure deviates from the intended pressure at the desired ramp rate by an undesired amount. A system for carrying out the method includes a flow controller for controlling operation of the supply system to deliver compressed gas from a source to a vessel through a supply line at a desired ramp rate. The system employs a pressure monitor downstream of a control valve for measuring the pressure of gas directed into the vessel and transmitting pressure-related data to the flow controller, which closes the control valve to discontinue filling of the vessel if the actual pressure exceeds a permissible deviation from the intended pressure.

The pressure vessel of the present invention comprises an inner shell capable of serving as a gas barrier and a pressure resistant outer shell provided to cover the inner shell, said outer shell being made of an FRP comprising reinforcing fibers and a resin and is 35 GPa or more in tensile modulus and 1.5% or more in tensile breaking strain. The present invention can provide a pressure vessel not only light in weight,.but also excellent in retaining its internal pressure against repetitive impacts and also excellent in reliability. The process for producing a pressure vessel of the present invention comprises the step of forming a pressure resistant outer shell made of an FRP comprising reinforcing fibers and a resin and is 35 GPa or more in tensile modulus and 1.5% or more in tensile breaking strain, around an inner shell capable of serving as a gas barrier, by a filament winding method or a tape winding method. The present invention can produce a pressure vessel excellent in retaining its internal pressure, excellent in reliability, and light in weight at a low cost.

A method for quick filling a vehicle hydrogen storage vessel with hydrogen, the key component of which is an algorithm used to control the fill process, which interacts with the hydrogen dispensing apparatus to determine the vehicle hydrogen storage vessel capacity.

The compressor-evaporator system for liquefied gas contained in a tank comprises, in addition to a deice for evaporation by heat exchange with a liquid and devices for conditioning and transferring gas to a pipeline, a motor-driven turbopump comprising a rotary assembly of high bending stiffness on a common shaft line, with at least one high pressure pump, a turbine, and a central electrical machine capable of being used in motor mode or in generator mode. The rotary assembly of the motor-driven turbopump is adapted to present a high speed of rotation, greater than 12,000 rpm, while remaining outside ranges for exciting critical speeds in rotation. All of the internal portions of the motor-driven turbopump are immersed in a cryogenic fluid that is the same as the liquefied gas contained in the tank. The internal cavities of the motor-driven turbopump that are under different thermodynamic conditions are separated by contactless dynamic seals. Electronic power circuits connected to an electricity network control the central electrical machine in motor mode or generator mode.

A light weight high performance vessel, e.g., tank and method of making same which is produced primarily from reinforced plastic composite materials. The vessel can be used for the containment of liquids or pressurized gases. The tank is comprised of an inner shell which is split to remove a mandrel on which it is formed and to install components in the inner shell. The inner shell pieces are then secured together by means of a joinder ring. An outer shell is then formed around and completely encapsulates the inner shell. There is also no need for the employment of an inner liner although one can be used.
