Apparatus for, and a method of, withdrawing liquefied cryogenic fuel stored in a primary insulated storage tank at a relatively low pressure and temperature; increasing the pressure of the withdrawn liquefied cryogenic fuel through a heat exchanger to warm the liquefied cryogenic fuel to a subcooled or near saturated liquid condition; and feeding the warmed and pressurized liquefied cryogenic fuel to an insulated tank on a vehicle at a refueling facility, said vehicle using liquefied cryogenic fuel as its fuel and the insulated vehicle fuel tank being adapted to safely contain and store the liquefied cryogenic fuel in liquid form, at an approximate saturated condition.

Method and apparatus for fueling vehicles with liquefied cryogenic fuel

Apparatus for, and a method of, withdrawing liquefied cryogenic fuel stored in a primary insulated storage tank at a low pressure and at a temperature close to its boiling point; increasing the pressure of the withdrawn liquefied cryogenic fuel and then feeding the pressurized liquefied cryogenic fuel through a heat exchanger to warm the liquefied cryogenic fuel to a subcooled or near saturated liquid condition; and feeding the said warmed and pressurized liquefied cryogenic fuel to an insulated tank on a vehicle at a refueling facility, the vehicle using liquefied cryogenic fuel as its fuel and the insulated vehicle fuel tank being adapted to safely contain and store the said liquefied cryogenic fuel in liquid form, at an approximate saturated condition.

The present invention relates to a method and system for storing cold fluid. The system includes a main tank and an auxiliary tank that are in fluid communication, and the auxiliary tank receives vapor and expanding fluid as the cold fluid in the main tank warms thereby avoiding overpressurization of the system.

Method and system for storing cold liquid

A method and apparatus for limiting the level of cold liquid within a vessel by sensing the expansion of cold liquid due to ambient heat leak, and venting pressurized vapor from the vessel to reduce the rate of expansion of the cold liquid.

An aqueous ice slurry is fed by a conduit from a freeze exchanger directly to one or more heat exchangers for cooling or air conditioning one of more enclosed or defined spaces. Warm water withdrawn from the heat exchangers is returned, with or without prior cooling, to the freeze exchanger to be converted into aqueous ice slurry. Warm water from the heat exchangers may be fed to a central thermal energy storage tank containing a bed of ice to cool the water and the cold water is fed to the freeze exchanger to form aqueous ice slurry. When heat exchangers have coils too small for an aqueous ice slurry to flow through the slurry is mixed with warm water from the heat exchangers to melt the ice and produce cold water which can be passed through the heat exchangers.

Apparatus and method for cooling using aqueous ice slurry

LNG is pumped to high pressure, vaporized, further heated and then expanded to create rotary power that is used to generate electrical power. A reservoir of carbon dioxide at about its triple point is created in an insulated vessel to store energy in the form of refrigeration recovered from the evaporated LNG. During peak electrical power periods, liquid carbon dioxide is withdrawn therefrom, pumped to a high pressure, vaporized, further heated, and expanded to create rotary power which generates additional electrical power. The exhaust from a fuel-fired combustion turbine, connected to an electrical power generator, heats the high pressure carbon dioxide vapor. The discharge stream from the CO.sub.2 expander is cooled and at least partially returned to the vessel where vapor condenses by melting stored solid carbon dioxide. During off-peak periods, CO.sub.2 vapor is withdrawn from the reservoir and condensed to liquid by vaporizing LNG, so that use is always efficiently made of the available refrigeration from the vaporizing LNG, and valuable peak electrical power is available when needed by using the stored energy in the CO.sub.2 reservoir.
