摘要:
Example integrated cryogenic hydrogen tank systems and methods for operating the same are disclosed herein. An example system comprises a first cryogenic tank coupled to a second cryogenic tank via a liquid hydrogen (LH2) transfer flowline and a gaseous hydrogen (GH2) transfer flowline, the LH2 transfer flowline and the GH2 transfer flowline to maintain a fuel level and a vapor pressure across the system, the fuel level corresponding to a cryogenic liquid; an inlet port connected to one of the first cryogenic tank or the second cryogenic tank; an LH2 extraction flowline connected to at least one of the first or second cryogenic tanks to supply the cryogenic liquid to a fuel management system; and a pressure safety system coupled to at least one of the first or second cryogenic tanks via a GH2 extraction flowline.

This disclosure includes fuel tank fittings, fuel systems and fueling stations having the same, and related methods. Some fuel tank fittings have a first end including a connector configured to be sealingly coupled to an outlet of a fuel tank, wherein the connector has a connection axis, a second end including two or more first ports, each positioned such that the connection axis does not extend therethrough, a first interior passageway extending from the connector, and two or more second interior passageways connecting the first interior passageway to the first ports such that, for each of the first ports, fluid is permitted to flow from the connector, through the first interior passageway, through one or more of the second interior passageways, and out of the first port without flowing through a valve.
摘要:
A compressed natural gas storage and dispensing system having descending pressure bulk storage banks in fluid communication with a supply source for CNG and dispensing storage banks in fluid communication with the descending pressure bulk storage bank, both banks being in fluid communication with fuel dispensers, wherein the delivery pressure of the CNG during, simultaneous refueling of CNG powered vehicles is equalized.
摘要:
The invention provides a hydrogen dispensing system comprising: a feed vessel for storing liquid hydrogen having an inlet and an outlet; a flash drum having an inlet and an outlet; a dispenser for dispensing gaseous hydrogen at a pressure of greater than 300 bar, having an inlet and an outlet wherein the feed vessel outlet is in fluid communication with the flash drum inlet, the flash drum outlet is in fluid communication with the dispenser inlet and there is no compression apparatus between the feed vessel outlet and the dispenser outlet. The invention also provides a method of providing gaseous hydrogen to a vehicle.
摘要:
A fuel cell powered vehicle is disclosed having a fuel tank, wherein the fuel tank is disposed on an undercarriage of the vehicle and has a substantially conical shape to militate against interference with a function of a suspension system of the vehicle.
摘要:
A method of making a cylindrical pressure vessel (11) with a large diameter port in its sidewall includes the step of providing a mandrel (23) of desired diameter and filament winding upon the same. After winding one overall innermost layer, an annular reinforcement belt (16) is helically wound atop a defined region using a band (60) of resin impregnated parallel strands (39) under tension. The annular belt (16) is then itself helically overwound with the resin impregnated parallel strands of filamentary material under tension to provide two complete outer layers. After curing and removal from the mandrel (23) at least one aperture (71) is cut in the sidewall within the reinforcement belt (16) and a side port fitting (75) is installed in the aperture (71).
摘要:
Apparatus wherein the compression heat of refueling of an on board vehicle tank is evacuated from the interior of the on board tank by a heat absorber within the tank through a radiator external to the tank and in which a coolant circulating from the heat absorber within the tank to the external radiator [and/or an associated blower system] is powered by the mechanical energy of the refueling gas as the gas traverses a turbine from the high pressure refuel depot to the low pressure on board tank. The turbine powers the gas cooling system.
摘要:
Methods of treating and sanitizing foods and other targeted objects, including the use of ozone and a method for providing a liquid dosed with pressurized ozone. The ozonated liquid of the invention is particularly useful for treating food products, food storage, and food transportation devices as well as treating water, or other target objects. Included is a method or pressurizing an ozone-containing stream without destroying the ozone or contaminating the stream with oil or water. The pressurized ozone-containing stream is then used to dose a liquid, which in turn is used to sanitize or treat a target object.
摘要:
The structural platform (11) of the vehicle comprises two tanks (T1) and (T2) for the storage on a vehicle of fluids under pressure. Each tank comprises at least one network of cells (2) connected to one another via orifices (3), the orifices being conformed so that the flow of fluid caused by the consumption of fluid necessary for the use of the vehicle exhibits only pressure drops which do not affect the use, and being conformed so that, in the event of rupture of one or more cells (2), the leakage flow causes sufficiently large pressure drops to limit the flow thereof.
