An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a compressor.

Described herein are at least systems and methods for cryogenic fluid delivery which utilize pumpless delivery of cryogenic fluid. The systems and methods utilize hydraulic pressure, saturation pressure, or a combination of both hydraulic pressure and saturation pressure to deliver cryogen to a use device, such as an engine.

A system that includes a marine vessel with a vaporizer skid disposed on the marine vessel. The vaporizer skid is configured to convert a liquid to a gas. The system further includes a first tank disposed on the marine vessel that is configured to store the liquid. The system further includes a plurality of header modules disposed on the marine vessel. The plurality of header modules form a piping network that provide a first flow path from the first tank to the vaporizer skid and a second flow path from the vaporizer skid to a connective interface. The connective interface is configured to provide a flow path from at least one of the plurality of header modules to an end-user system.

The present invention relates to liquefied gas treatment system and method, and the liquefied gas treatment system includes: a liquefied gas supply line connected from a liquefied gas storing tank to a source of demand; a heat exchanger provided on the liquefied gas supply line between the source of demand and the liquefied gas storing tank, and configured to heat exchange liquefied gas supplied from the liquefied gas storing tank with heat transfer media; a media heater configured to heat the heat transfer media; a media circulation line connected from the media heater to the heat exchanger; a media state detecting sensor provided on the media circulation line, and configured to measure a state of the heat transfer media; and a controller configured to set a coagulation prevention reference value for preventing the heat transfer media from being coagulated, and change a flow rate of the heat transfer media flowing into the media heater or calories supplied to the heat transfer media by the media heater on the basis of a state value of the heat transfer media by the media state detecting sensor and the coagulation prevention reference value.

The present disclosure provides a gas storage device. In an embodiment, the gas storage device includes a cylinder with opposing ends. An endcap is present at each end. The cylinder and the endcaps form an enclosure. Each endcap includes a connector. A diaphragm is located in the enclosure. The diaphragm includes an annular sidewall. The device includes an inner chamber defined by an inner surface of the sidewall, and a storage space between an interior surface of the cylinder and an outer surface of the sidewall. A metal hydride composition is located in the storage space.

A method for precooling fuel delivery components of a machine having an engine fueled by a cryogenically-stored fuel is described. The fuel delivery components may be configured to operate at an operating temperature at or below a boiling point of the cryogenically-stored fuel. The method may comprise, in a vapor precooling mode, cooling the fuel delivery components to a temperature approaching the operating temperature with a vapor of the fuel taken from a reservoir cryogenically storing the fuel. The method may further comprise, in a liquid precooling mode, further cooling the fuel delivery components to the operating temperature with a liquid of the fuel taken from the reservoir.

A system for cooling at least one electrical component of a machine. The machine is powered by a liquefied natural gas (LNG). The system includes at least one blower and at least one heat exchanger. The at least one blower is arranged to direct an air flow towards the at least one electrical component. The at least one heat exchanger is arranged upstream of the at least one electrical component. The at least one heat exchanger is using LNG as the coolant for cooling the air flow being directed towards the at least one electrical component.

A system for dispensing a cryogenic fluid includes a bulk tank configured to contain a supply of a cryogenic liquid, a first sump and a first liquid feed valve configured to direct liquid from the bulk tank to the first sump when in an open condition and to prevent transfer of liquid from the bulk tank to the first sump when in a closed condition. A first positive displacement pump is positioned within the first sump and configured to pump and be submerged in cryogenic liquid when the first sump contains cryogenic liquid above a predetermined liquid level within the first sump. A delivery line is in fluid communication with an outlet of the first positive displacement pump and is configured to direct cryogenic fluid from the first positive displacement pump to a use device when the first positive displacement pump is activated.

An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a compressor.

A cryogenic fluid dispensing system having a tank that holds cryogenic liquid and manages heat within the system is disclosed. The cryogenic liquid dispensing system optionally includes a basin and/or a heat exchanger within the tank for managing heat within the system.
