Definitions

  • the invention relates to a method for simultaneously refueling a plurality of vehicles with hydrogen, as well as a system for this purpose, e.g. a hydrogen filling station.
  • Hydrogen which is used as fuel for vehicles, for example, can be provided via so-called hydrogen filling stations.
  • Two types of hydrogen filling stations can be distinguished.
  • the first type uses liquid hydrogen as a source and compresses the hydrogen into a liquid state, i.e. in liquid form.
  • the second type has a gaseous hydrogen source and compresses the hydrogen into a gaseous state, i.e. the hydrogen is at least initially obtained in gaseous form and is also compressed into a gaseous state.
  • two basic system areas can be distinguished in a hydrogen filling station.
  • the first system area concerns the compression of the hydrogen, its storage, as well as its conditioning and cooling.
  • the second system area includes a hydrogen dispenser and the associated refueling equipment such as breakaway and refueling couplings and the refueling hose.
  • the task is to make refueling vehicles with hydrogen as cost- and energy-efficient as possible, but also as quick as possible.
  • the invention deals with the refueling of vehicles with hydrogen as well as corresponding systems and their operation.
  • hydrogen filling stations in particular come into consideration as such systems.
  • the first type uses liquid hydrogen as a source and compresses the hydrogen in liquid form.
  • the second type has a gaseous hydrogen source, ie receives the hydrogen in gaseous form, and compresses the hydrogen in gaseous form.
  • the present invention deals with the second type of hydrogen filling stations or generally the compression, storage and provision of hydrogen.
  • hydrogen is usually compressed in several stages (typically intermediate stage and cylinder jacket cooled) to up to 1000 bar and stored in medium and/or high pressure banks at e.g. between 500 and 1000 bar.
  • the hydrogen is usually specifically preconditioned in terms of pressure and mass flow using a so-called pressure ramp controller.
  • the current standards e.g. SAE J2601, JPEC-S0003, Phryde protocol or CEP protocol
  • gaseous hydrogen heats up due to the negative Joule-Thomson effect in the course of isenthalpic relaxation.
  • hydrogen is obtained and compressed using a compression device.
  • the compression device can in particular have an ionic compressor or be designed as such.
  • the hydrogen is obtained from one or more electrolysis units (or an electrolysis plant, in particular on an industrial scale).
  • the compressed hydrogen is then fed to a filling system with a plurality of refueling paths.
  • hydrogen is simultaneously fed to the plurality of refueling paths, in particular to each refueling path.
  • hydrogen is obtained and delivered to a connected vehicle (ie, to a tank of the vehicle in question) - in total, hydrogen is delivered to several connected vehicles at the same time.
  • This delivery of hydrogen to vehicles takes place in each of several Refueling cycles, i.e. simultaneous refueling is carried out on the one hand, but also sequential refueling on the other. It is not necessary for the same number of vehicles to be refueled in each refueling cycle.
  • Each refueling path can have, for example, a changeover valve, a mass flow-controlled pressure regulator, and a coupling device for connection to a vehicle.
  • each refueling path can be cooled, in particular by means of a water/glycol-air heat exchanger. Cooling to 10 °C is feasible, for example.
  • the energy required for optional ambient cooling is very low, as only electrical energy is needed for a small water pump, for example, to maintain the flow.
  • the hydrogen after it has been compressed by means of the compression device, is fed at least partially to a medium-pressure storage system if required. From the medium-pressure storage system, the hydrogen is then fed (again) to the compression device if required (internal bypass, so partial overflow into the tank system without compression is possible) and then fed to the plurality of refueling paths.
  • a medium-pressure storage system From the medium-pressure storage system, the hydrogen is then fed (again) to the compression device if required (internal bypass, so partial overflow into the tank system without compression is possible) and then fed to the plurality of refueling paths.
  • This is done in particular in such a way that an enthalpy flow into the respective vehicles or their vehicle tanks has a sufficient minimum in order to mitigate tank overheating and simultaneously to fully refuel as many vehicles as possible in a limited period of time. For example, during a predetermined period of time in which no vehicle is to be refueled (e.g.
  • the hydrogen is at least partially fed to the medium-pressure storage system, and during a predetermined period of time in which the large number of vehicles are to be refueled (e.g. at night), hydrogen is then fed to the compression device and then to the large number of refueling paths so that the vehicles are refueled.
  • the gas hydrogen
  • the gas can be bypassed within the compressor system so that the pressure gradient between the vehicle tank and the medium-pressure storage can be used for partial overflow refueling. Only when the vehicle tank is sufficiently high and overflow is no longer possible are the respective vehicles fully filled using what is known as compressor refueling.
  • Such a medium-pressure storage system can, for example, be designed for a pressure of around 200 bar (or a value between 150 bar and 250 bar) and is used for intermediate storage.
  • the use of the medium-pressure storage system is particularly useful when obtaining hydrogen from electrolysis units, but it is also conceivable to use the medium-pressure storage system when obtaining hydrogen from other sources, if necessary or expedient.
  • a mass flow of the hydrogen compressed by the compression device and supplied to the filling system is limited depending on a predetermined maximum temperature of the hydrogen.
  • the maximum permitted average mass flow at an ambient temperature of 45 °C can be approximately 6.3 kg/h for the underlying tank system volume. In this way, overheating is avoided.
  • the proposed method of simultaneously refueling vehicles allows, for example, seven vehicles with a so-called Type 4 tank system (the tank system volume used in the calculation is 1.56 m 3 ) to be filled in batches simultaneously and uncooled with up to 30 kg of hydrogen each within five hours without causing the tank to overheat.
  • the compressor system used e.g. ionic compressor
  • the compressor system used can provide a mass flow of up to 52 kg/h, with a mass flow control controlled, for example, by means of a frequency converter, limiting the maximum permitted mass flows in order to comply with the temperature limits of the respective tank systems.
  • the maximum permitted average mass flow at 45 °C is Environment, for example, around 6.3 kg/h for the underlying tank system volume.
  • a pressure surge to determine the starting pressure and a leak check can be carried out after the vehicles have been coupled as part of a fully automated controlled step chain.
  • the sequential tranche processing enables a shortened waiting time, for example to get municipal bus fleets ready for the next shift.
  • the filling system is set up for seven or a multiple of seven vehicles that can be connected. For example, seven vehicles can be filled up first, and as soon as these are fully filled up, the next seven vehicles can be filled up immediately.
  • seven vehicles can be filled up first, and as soon as these are fully filled up, the next seven vehicles can be filled up immediately.
  • other numbers of vehicles can also be filled up at the same time.
  • FIG. 1 a system 100 according to the invention is shown schematically in a preferred embodiment, by means of which a method according to the invention can also be carried out.
  • This is a simplified process diagram.
  • a concrete example of a system 100 designed as a hydrogen filling station with an ionic compressor as a compression device 130 and a filling system 140 is shown.
  • the system 100 serves to simultaneously fill a large number of vehicles with hydrogen, although only one vehicle 150 is shown as an example.
  • an electrolysis device 110 is shown, from which hydrogen a is obtained and fed to the compression device 130.
  • the valve 112 can be opened.
  • the electrolysis device 110 can be part of the system 100, but it does not have to be; for example, the hydrogen can also be transported via a pipeline from the electrolysis device 110 to the system 100 or there to the compression device 130.
  • Hydrogen can be supplied from the compression device 130 to the filling system 140.
  • the system 100 also has a medium-pressure storage system 120.
  • the medium-pressure storage system 120 can, for example, comprise one or more storage tanks or storage banks in which hydrogen can be stored at approximately 200 bar.
  • the hydrogen can be supplied at least partially to the medium-pressure storage system 130 if required; this is shown with stream d.
  • the valve 122 can be opened.
  • the hydrogen shown here as stream d, can be supplied from the medium-pressure storage system 120 to the compression device 130 if required and then, like stream b, to the filling system 104.
  • the valve 124 can be opened.
  • the filling system 140 has, for example, seven refueling paths 140.1, 140.2, 140.3, 140.4, 140.5, 140.6, 140.7, to each of which hydrogen can be or is supplied from the compression device 130.
  • the refueling path 140.1 has a switching valve 142.1, a mass flow-controlled pressure regulator 144.1, a heat exchanger 146.1 and a coupling device 148.1 for connection to the vehicle 150, which then can be fueled with hydrogen, here electricity e
  • the heat exchanger 146.1 can be, for example, a water or glycol-air heat exchanger.
  • the filling system 140 can also comprise further refueling paths, e.g. a further seven or fourteen refueling paths, or generally 7 n refueling paths with n being a number greater than or equal to 1 and e.g. a maximum of 49.
  • the filling system 140 can be set up to switch from the seven refueling paths 140.1, 140.2, 140.3, 140.4, 140.5, 140.6, 140.7 shown to other seven refueling paths in order to refuel vehicles connected there, e.g. in a subsequent refueling cycle.
  • the electrolysis device 110 produces hydrogen at 36 kg/h, for example, which is compressed using the compression device 130 and fed into the medium-pressure storage system 120 at around 200 bar. This takes place, for example, at a time of day when no vehicle needs to be refueled. If, in the example shown, more than seven vehicles, e.g. an entire vehicle fleet, have to be refueled simultaneously, this can be done in batches of seven vehicles each.
  • the compression device 130 can be used to simultaneously refuel seven vehicles, each with up to approx. 30 kg of hydrogen, even at elevated ambient temperatures of more than 39 °C.
  • the compression device 130 takes the required amount of hydrogen from the medium-pressure storage system 120, which serves as a buffer storage here. As part of the refueling process of the first vehicle tranche of, for example, seven vehicles, these are coupled to the filling system 140, a so-called header dispenser, which can accordingly comprise seven filling points (the coupling devices mentioned).
  • the refueling can be carried out completely independently.
  • the aforementioned switching valves of the filling system 140 can enable the respective refueling processes of the vehicle tranches (here consisting of seven vehicles). After the seven vehicles have been filled, it is possible to switch to the next seven vehicles by switching the relevant switching valves.
  • the filling system 140 can also be cooled with the aforementioned cooling or heat exchangers to e.g. 10 °C or at least approximately to ambient temperature.
  • the energy required for this ambient cooling is very low, since only a small water pump requires electrical energy to maintain the flow.
  • FIG 2 a system 200 according to the invention is shown schematically in a further preferred embodiment, by means of which a method according to the invention can also be carried out.
  • This is a simplified process diagram.
  • a concrete example of a system 200 designed as a hydrogen filling station with an ionic compressor as compression device 130 and a filling system 140 is shown.
  • the system 100 serves to simultaneously fill a large number of vehicles with hydrogen, although only one vehicle 150 is shown as an example.
  • the system 100 does not have an electrolysis system, for example, but instead the hydrogen, stream a, is received from a tanker 210 (which is only shown very schematically here) and fed to the compression device 130 and then to the filling system 140.
  • the valve 212 e.g. on the tanker and/or on the compression device 130
  • the tanker can also be provided in parallel or one after the other.
  • no medium-pressure storage system is provided here either, since the tankers themselves form a storage system for the hydrogen anyway.
  • the maximum permitted average mass flow at 45 °C ambient is around 6.3 kg/h for the underlying tank system volume.
  • No human personnel is required to complete the refueling successfully, as the process can be fully automated. Only the coupling and uncoupling of the vehicles can be carried out by human personnel.
  • the pressure surge to determine the starting pressure and the leak check can be carried out after the vehicles have been coupled in the course of a fully automated controlled step chain.
  • the sequential tranche processing enables a shortened waiting time, for example to get municipal bus fleets ready for the next shift. No medium-pressure cascade is required for this and the Refueling is carried out online by the compression device, the flow control of which can be kept very simple (e.g. a piston compressor with frequency converter-controlled speed control).
  • the refueling ramps in the individual refueling paths can also be varied dynamically during the filling or refueling process.
