DEVICE AND METHOD FOR GUIDING HYDROGEN CHARGING STATION
In a device and a method for guiding a hydrogen fueled vehicle based on a hydrogen pressure of a fuel tank of the hydrogen charging station, information on a hydrogen charging station including the hydrogen pressure of the fuel tank of the hydrogen charging station is received from a server, and a charging station determined to be suitable for charging the hydrogen fueled vehicle is selected in consideration of an importance of each item obtained from a user of the hydrogen fueled vehicle based on items including at least one of a price of hydrogen charging, a charging standby time, a charging taking time, whether the hydrogen fueled vehicle is able to be fully charged, and a distance to the hydrogen charging station determined based on the information on the hydrogen charging station.
Hydrogen fueling safety indicator
One or more indicators provide an indication of fueling status of a hydrogen powered vehicle. One or more sensors detect temperature and/or other characteristics of the fuel provided to the vehicle and provide an electrical signal to one or more of the indicators to permit an indication of fueling status. The indicators, which may be visual and/or audible, may be positioned on the fueling apparatus and on the vehicle in the vicinity of a fueling receptacle. The indicators may also be positioned elsewhere on the vehicle and may be separate from the vehicle such as on or around a fueling station and/or on separate computerized devices.
FUELING STATION FOR SUPPLY OF LIQUID ORGANIC HYDROGEN CARRIERS AND METHOD OF OPERATION
Apparatus, methods and technologies are described for utilizing a liquid organic hydrogen carrier (LOHC) fueling station to supply fresh or hydrogen laden LOHC and to recover spent or hydrogen depleted LOHC liquid fuels from mobile vehicles and tanker trucks to support the use of LOHC as carbon-neutral hydrogen fuels to power vehicles, to generate and store electricity, to generate and capture hydrogen, and to replace the use of conventional hydrocarbon fuels while maintaining an overall carbon-neutral balance with respect to the environment. The disclosure includes apparatus, methods and technologies to resupply a modular LOHC fueling station, to store, dispense and recover LOHC fuels, and to transfer the LOHC liquid fuels while balancing displaced vapors to maintain an overall carbon-neutral environmental footprint.
Method for filling tanks of hydrogen-fueled vehicles
A hydrogen refilling station for filling tanks of fuel cell electric vehicles includes a liquid hydrogen tank that feeds liquid hydrogen to an upstream end of a filling circuit that also includes a heat exchanger. The heat exchanger exchanges heat between the liquid hydrogen and heat transfer fluid flows to thereby cool the heat transfer fluid and vaporize the liquid hydrogen to provide a supply of high pressure hydrogen gas for filling hydrogen-fueled vehicle tanks at a downstream end of the circuit. Because the liquid hydrogen is surrounded by the heat transfer fluid inside the heat exchanger, little if any fogging occurs.
Hydrogen filling system
A hydrogen filling system includes a first tank and a second tank that are configured to be filled with hydrogen and communicate with each other, a first hydrogen feeder and a second hydrogen feeder configured to feed hydrogen to the first tank and the second tank, and a controller configured to control the first hydrogen feeder and the second hydrogen feeder. The controller estimates a hydrogen fill factor of the first tank and the second tank, based on a first internal temperature of the first tank and a second internal temperature of the second tank, and a first pressure of hydrogen gas fed from the first hydrogen feeder and a second pressure of hydrogen gas fed from the second hydrogen feeder. The controller is configured to stop the first hydrogen feeder and the second hydrogen feeder when the hydrogen fill factor reaches a predetermined threshold fill factor.
STRATEGIES FOR SAFE FAST-FILL OF COMPRESSED GAS TANKS
A type IV conformable pressure vessel is provided comprising an elongated folded tank and a valve assembly configured to pass fluid into and out of an interior of the tank through first and second filling couplers directly connected to a respective first and second end of the tank. The tank has at least two chambers for the storage of fluid. The valve assembly receives fluid from an external source, selectively provides the external fluid through a Venturi nozzle into a mixing chamber, recirculates fluid from the second end of the tank into the mixing chamber, and delivers the mixture of the recirculated fluid and the external fluid to the first end of the tank.
GAS FUELING SYSTEMS AND METHODS WITH MINIMUM AND/OR NO COOLING
Gaseous fueling systems and methods are provided for dispensing fuel to a vehicle or container. The distribution systems speed up the filling process and may eliminate the use of expensive cooling systems required in the art. The methods utilize sequences of filling and emptying the vehicle gas storage tank to control the temperature of the gas inside the tank. These filling and emptying sequences may overlap. The methods repeatedly dispense fuel to the vehicle fuel tank at a first flow rate and for a first period of time and remove fuel from the fuel tank at a second flow rate for a second period of time, which periods may overlap, to maintain fuel temperature within a desired temperature range and until the vehicle fuel tank is filled to a desired level. In addition, the fill-up mass flowrate can be maximized to system capabilities so a fill-up can be completed in about one minute.
CRYOGENIC FLUID FUELING SYSTEM
A cryogenic fluid fueling system includes a first container configured to contain a first cryogenic liquid with a first headspace being positioned above the first cryogenic liquid. A heat exchanger vaporizes a portion of the first cryogenic liquid such that pressure within the first container is raised as vaporized cryogen moves into the first headspace. A second container is configured to contain a second cryogenic liquid with a second headspace being positioned above the second cryogenic liquid. A condensing coil is positioned within the second headspace of the second container and fluidically connected to the first interior of the first container such that a portion of the first cryogenic liquid is propelled into the condensing coil and is warmed to provide a first cryogenic vapor.
FUEL CELL VEHICLE TO REFUEL ANOTHER VEHICLE
A system for a fuel cell vehicle includes a providing fuel cell fuel port, a fuel cell fuel storage tank, a fuel cell fuel flowmeter, and a pressure regulator. The fuel cell fuel storage tank is fluidically coupled to the providing fuel cell fuel port. The fuel cell fuel flowmeter is coupled between the fuel cell fuel port and the fuel cell fuel storage tank and is configured to measure flow of fuel cell fuel from the fuel cell fuel storage tank to the providing fuel cell fuel port. The pressure regulator is coupled between the fuel cell fuel flowmeter and the fuel cell fuel storage tank and is configured to control pressure of fuel cell fuel flowing from the fuel cell fuel storage tank to the providing fuel cell fuel port.
DEVICE, METHOD, AND SYSTEM OF GUIDING VEHICLE TO HYDROGEN FILLING STATION
A guide system for selecting from among a plurality of hydrogen filling stations includes a first communication device to receive information on a status of a hydrogen fuel dispenser from each of the plurality of hydrogen filling stations, respectively; a second communication device to receive a request for guidance to one of the hydrogen filling stations, from a vehicle terminal; and a controller to guide a hydrogen fuel vehicle having the vehicle terminal to a selected one of the hydrogen filling stations allowing the hydrogen fuel vehicle to occupy a hydrogen fuel dispenser having reference pressure, at a time point when the hydrogen fuel vehicle arrives, such that the hydrogen fuel vehicle is guided to the optimal hydrogen filling station to immediately fill hydrogen without standby time.
