Definitions

  • the present invention relates to a method for operating a fuel dispensing system for dispensing fuel, preferably cryogenic fuel like hydrogen, to a fuel dispensing system and to a cryogenic fuel station, for, e.g., hydrogen or natural gas.
  • fuel preferably cryogenic fuel like hydrogen
  • a cryogenic fuel station for, e.g., hydrogen or natural gas.
  • Vehicles like trucks, buses, vans or cars can be powered with cryogenic fuels.
  • Hydrogen for example, must be kept at a cryogenic temperature for storing and dispensing it into the vehicle. This also requires cooling down the dispensing equipment before any dispensing operation.
  • an improved way of providing fuel like hydrogen or other cryogenic fuel is an objection of the present invention.
  • the invention relates to fuel dispensing systems used for dispensing fuels like hydrogen (H2), natural gas (NG or LNG, liquefied natural gas) or other cryogenic fuels to fuel receivers like vehicles, e.g., trucks, buses, vans or cars.
  • fuel dispensing systems are used in fuel stations like hydrogen fuel stations or other cryogenic fuel stations.
  • Cryogenic fuels (or also other types of fuels) are typically stored in a reservoir at a fuel dispensing station or the like; in the reservoir, the fuel is held at low (cryogenic) temperatures, e.g., 20 K.
  • Such fuel also has to be transferred to a fuel dispensing apparatus (often only called dispenser), e.g., via pumps or another fuel supply system, via the fuel dispensing apparatus the fuel can be transferred to the fuel receiver. Due to the low temperature of the fuel, the fuel supply system and/or fuel dispensing apparatus, or at least parts thereof, have also to be cooled down. A cooling system can be provided for that.
  • a fuel station users typically arrive with their vehicle, park the vehicle at the fuel dispensing apparatus (dispenser), connect the fuel dispensing apparatus with the vehicle, and start dispensing or cause the fuel dispensing apparatus to do so. Depending on the type of fuel dispensing station, payment has to be made prior to the start of dispensing.
  • dispensing can start immediately after connecting (or, as the case may be, after payment), this can be different for fuel dispensing system where parts have to be cooled down.
  • cooling down of the fuel supply system and the fuel dispensing apparatus is stopped after a certain time period of no dispensing.
  • the fuel supply system and/or fuel dispensing apparatus, or at least parts thereof have to be cooled down again if a next user arrives for dispensing fuel.
  • a time period until the parts have sufficiently be cooled down may be up to 15 min. This results in a long waiting time for the user. In addition, this may cause the user to become careless as to connecting the fuel dispensing apparatus or the like.
  • a presence sensor i.e. the fuel dispensing system comprises - in addition to the fuel dispensing apparatus, the fuel supply system, and the cooling system - such presence sensor.
  • a fuel receiver like the vehicle can be detected. This means that, based on the sensor information, it can be determined whether a fuel receiver is present, e.g., within a pre-defined area.
  • a pre-defined area can be, for example, a vehicle lane next to the fuel dispensing apparatus.
  • Such fuel dispensing system is, thus, configured to detect presence of a fuel receiver like a vehicle by means of the presence sensor.
  • Such presence sensor is capable of or configured to detect the presence of a vehicle within at least a pre-defined distance from the sensor.
  • Preferred presence sensors that can be used are an inductive sensor (e.g., in form of or comprising a inductance loop), an infrared sensor, an ultrasound sensor, a video camera, a mechanical sensor (e.g., weight sensor). Also, two or more of them in combination could be used, be it of different or the same type.
  • the presence sensor can, for example, be of an analogue type, i.e., it will provide an electrical analogue signal indicating whether or not a vehicle is present.
  • the presence sensor is designed or configured for outdoor atmosphere, a minimum recommendation is, for example, -20°C to 60°C to reach a large number of countries.
  • the presence sensor is also designed or configured for explosive atmosphere.
  • the presence sensor is also in accordance with local norms or other requirements (e.g., ATEX for Europe, IECex for Australia, UL for USA, CSA for Canada, GOSTR-EX for Russia).
  • a minimum distance range of detection, for the presence sensor has to be, for example, between 0 mm and 1000 mm.
  • the cooling system is then caused to cool down the at least part of the fuel supply system and/or at least part of the fuel dispensing apparatus dispensing fuel apparatus, depending on the detection of the presence of a fuel. In an embodiment, it is detected, based on the sensor information, whether the fuel receiver is present within a pre-defined area with respect to the fuel dispensing system, and/or for at least a pre-defined time period.
  • the cooling system is caused to start cooling down the at least part of the fuel supply system and/or at least part of the fuel dispensing apparatus, if the fuel receiver is present within said pre-defined area and/or for at least said pre-defined time period.
  • Such pre-defined time period can be 10 or 15 seconds, for example.
  • the cooling system is further caused to stop cooling down the at least part of the fuel supply system and/or at least part of the fuel dispensing apparatus dispensing fuel apparatus, if the fuel receiver is not present within said pre-defined area and/or for at least a further pre-defined time period, after cooling down had been started. In this way, energy can be saved if no more vehicle is present to be fuelled.
  • the fuel dispensing apparatus is caused to start dispensing the fuel to said fuel receiver upon receiving a user input.
  • the user e.g., the driver of the vehicle to be fuelled
  • the user can be required to push a start button after having connected the fuel dispensing apparatus to the vehicle and, as the case may be, after having made a payment at the fuel station.
  • the invention also relates to a data processing device comprising or processor or other means for performing the method according to the invention or method steps thereof.
  • the data processing device may be a computer or server, for example in a so-called cloud or cloud environment.
  • a machine-readable storage medium is provided with a computer program or instructions stored thereon as described above.
  • Suitable storage media or data carriers for providing the computer program are in particular magnetic, optical and electrical memories, such as hard disks, flash memories, EEPROMs, DVDs and the like. It is also possible to download a program via computer networks (Internet, intranet, etc.). Such a download can take place by wire or cable or wirelessly (e.g. via a WiFi network, a 3G, 4G, 5G or 6G connection, etc.).
