A portable hydrogen refueling stations which can dispense gaseous hydrogen from one or more internal high pressure tanks. The refueling station can be refilled with a lower pressure hydrogen gas feed and then compressed for storage within the refueling station.

Systems for handling and/or dispensing hydrogen or a mixture of fuels containing hydrogen gas including refueling stations for hydrogen-powered vehicles. Pure hydrogen or various mixtures ratios of hydrogen and CNG may be dispensed. Hydrogen handling equipment may include a hydrogen generator, a pressurizing apparatus or compressor, pressure vessels, piping, valves, vent pipes, and/or a dispenser. Substantially vertical orientation of pressure vessels may reduce the amount of land required and facilitate installation in urban environments. Pressurization may take place before hydrogen generation to reduce the power required for pressurization. Safety features include enclosures and surrounding walls that lean away from the equipment. Any leaking hydrogen, fires, or explosions may be contained and/or directed upward, protecting human life and property. Systems may be shop assembled and certified.

A valve with a smart handle including a memory module to log relevant data. A sensor on the handle determines when the valve is open, and this triggers the start of timers and recording of the “open” event in a log in the memory module. When the valve is closed, the sensor triggers stopping of the timers and recording of the “closed” event in the log. The timer information is used to calculate the duration of the time “open” event, and this, together with the actual date and time of the opening and closing of the valve are recorded in the log. Other relevant information, such as cylinder fill date, cylinder I.D. number, batch number, and patient name or account number may also be logged in the memory module. The log of the events and the corresponding dates and times may be used to prepare invoices for billing gas treatments, for inventory control, and for other record-keeping and control functions.

A medical gas cylinder monitoring and alarm device is provided. The medical gas cylinder monitoring and alarm device is a portable device that provides a monitoring function for one or more cylinders and may be carried by a patient or respiratory therapist or may be removably affixed to a medical gas cylinder. The monitoring device is a processor based device adapted to receive selected user inputs for a specific medical gas cylinder application and determine the estimated time remaining before the medical gas cylinder is emptied. The device displays the time remaining for the medical gas cylinder and is also adapted to provide visual and audible alarm notifications when the gas cylinder is near empty.

Methods for loading a compressed fluid, such as natural gas, into and discharging the compressed fluid out of containment are provided. The compressed fluid is injected into a bottom portion of a container system for storage and/or transport until a target pressure is reached after which gas is withdrawn from an upper portion of the container system at a rate to maintain the target pressure while the compressed fluid is injected in the bottom portion. The compressed fluid is cooled through an expansion valve and by refrigerated chillers or by injecting a cold liquid of the same chemical composition as the compressed fluid, such as liquid natural gas, into the compressed fluid prior to injection into the container system. Withdrawal or discharge from the container system to a receiving facility begins with blow down from the bottom portion of the container system without a displacement fluid and continues until pressure falls below an acceptable differential pressure. The discharge stream is passed through a separator and a light gas from the separator is pressurized and injected into an upper portion of the container system to drive the compressed fluid out the bottom. The light gas is pressurized using either a compressor or a heated tank system, where two vessels operate in parallel, trapping and heating the light gas and then discharging to the container system from one while filling the other and alternating the operation between the two.

Described herein is a portable storage device that stores a hydrogen fuel source. The storage device includes a bladder that contains the hydrogen fuel source and conforms to the volume of the hydrogen fuel source. A housing provides mechanical protection for the bladder. The storage device also includes a connector that interfaces with a mating connector to permit transfer of the fuel source between the bladder and a device that includes the mating connector. The device may be a portable electronics device such as a laptop computer. Refillable hydrogen fuel source storage devices and systems are also described. The refillable system comprises a hydrogen fuel source refiner that includes the mating connector and provides the hydrogen fuel source to the storage device. Hot swappable fuel storage systems described herein allow a portable hydrogen fuel source storage device to be removed from a fuel processor or electronics device it provides the hydrogen fuel source to, without shutting down the receiving device or without compromising hydrogen fuel source provision to the receiving device for a limited time.

This disclosure describes a modular, monolithic pump-purge system which can be integrated into a modular, monolithic fluid handling system without creating a closed tolerance loop. In particular, the pump-purge system comprises a plurality of valves mounted on a modular and monolithic manifold which can be attached to the modular, monolithic fluid handling system. At least a portion, and preferably all of the fluid transfer conduits necessary for either applying a vacuum (or other evacuation means) to a fluid handling system conduit which is to be evacuated (pumped), or for transfer of flushing fluid within a conduit (purging) are present within monolithic manifolds of the fluid handling system. The modular, monolithic manifold of the pump-purge system contains openings and fluid flow conduits which correspond with openings and fluid flow conduits of the modular, monolithic fluid handling system, to enable evacuation or flushing of a selected fluid flow conduit within the fluid handling system. To avoid the formation of a closed tolerance loop, it is necessary that the pump-purge manifold or a portion of the modular, monolithic fluid handling system manifold to which it is attached be sufficiently free-floating to permit making of all necessary connections without creating stress which can lead to an increased rate of corrosion or failure of the connection. In a preferred embodiment gas handling system, the gas handling flow lines which make up the system are comprised of individual sticks of gas handling elements, each of which is attached to the manifold of the pump-purge system so that it is free-floating.

A fluid storage and dispensing system including a vessel for holding a fluid, an adjustable set point pressure regulator in the interior volume of the vessel, a dispensing assembly in fluid flow communication with the regulator for dispensing fluid at a pressure determined by the set point of the regulator, and an adjusting assembly exterior to the vessel for in situ adjustment of the set point of the internally disposed regulator. By such arrangement, fluid storage and dispensing operations can have respectively differing regulator set point pressures, as for example a sub-atmospheric pressure set point for storage and a super-atmospheric pressure set point for dispensing.

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.

A container for gas storage tanks in a vehicle is disclosed as part of a fuel storage system. The container is dimensioned to include one or more storage tanks along with a flow control device, such as a pressure regulator or automatic valve. The container does not form a fluid-tight containment around the storage tank and includes one or more ventilation openings to allow a gas within the container to be vented therefrom. There is also one or more drain openings in the container to allow liquid within the container to be drained therefrom.

A fluid distribution system for supplying a gas to a process facility such as a semiconductor manufacturing plant. The system includes a main fluid supply vessel coupled by flow circuitry to a local sorbent-containing supply vessel from which fluid, e.g., low pressure compressed gas, is dispensed to a fluid-consuming unit, e.g., a semiconductor manufacturing tool. A fluid pressure regulator is disposed in the flow circuitry or the main liquid supply vessel and ensures that the gas flowed to the fluid-consuming unit is at desired pressure. The system and associated method are particularly suited to the supply and utilization of liquefied compressed gases such as trimethylsilane, arsine, phosphine, and dichlorosilane.
