Definitions
- the invention relates to a method and system for distribution of hydrogen.
- Hydrogen can be transported in liquid form or gaseous state.
- Advantage of gas transport is that no special provisions are necessary to make the hydrogen liquid (which is normally done by cooling); a disadvantage is the higher transport volume per energy unit.
- hydrogen is usually, in gaseous state under a high pressure, transported in dedicated transport trailers, which provide local filling stations with the hydrogen.
- various, mutually spaced apart filling stations can be filled up with hydrogen, in order that vehicles can be filled up - locally - via the filling stations.
- this requires trailer road transport, which is relatively costly and inefficient.
- Another form of gas transport comprises the transport of natural gas to households and other natural gas consumers, via a nationwide natural gas transport network.
- combustion of natural gas leads to emission of carbon dioxide. That is why hydrogen is regarded as a possible replacement of natural gas.
- a gaseous mixture of hydrogen and natural gas also called Hydrogen
- HENG Enriched Natural Gas
- gas hnes to provide downstream HENG users (for example, CH boilers suitable for such a mixture) with fuel.
- HENG users for example, CH boilers suitable for such a mixture
- gas combustion heating apparatuses of the end users obviously need to be suitable to combust the alternative fuel.
- the present invention contemplates an improved method, and system, for distribution of hydrogen.
- the invention contemplates a method with which a number of filling stations can be provided with hydrogen efficiently.
- a method for distributing fuel comprises transport from a fuel production apparatus to at least one filhng station, for example a transport means filling station, wherein the fuel to be transported substantially consists of hydrogen, wherein the fuel is transported through a transport network by means of a transport medium, wherein the hydrogen is at least partly separated from the transport medium before the hydrogen is supplied to the filhng station.
- hydrogen can be transported in an efficient manner over a relatively long distance (e.g., tens of kilometers), utilizing (in particular, mixed with) a transport medium, to be subsequently wholly or partly separated/removed locally from the transport medium for the purpose of passing on to, more specifically utilization by, the filling station.
- a transport medium e.g., tens of kilometers
- the deployment of separate hydrogen transport trailers can be limited or avoided altogether, with concomitant advantages thereof.
- an already existing gas transport infrastructure is employed to transport the mixture of the hydrogen and the transport medium.
- This infrastructure can for instance comprise a natural gas transport network, with the transport medium consisting substantially of natural gas.
- the hydrogen is transported in gaseous state (namely in a state mixed into the transport medium) through the network.
- the transport medium is preferably also gaseous, and may consist of one or more transport medium gases.
- the transport medium as such may for example comprise a gas or gas mixture of substantially methane (for example more than 70% by volume methane, in particular at least 80% by volume methane), while the transport medium can also contain other gases, for example, other hydrocarbons (ethane, propane, butane, pentane and/or butane), nitrogen and carbon dioxide (preferably less than 1% by volume carbon dioxide).
- the transport medium to be used may even already contain a limited amount of hydrogen before the transport medium is provided with the hydrogen to be transported.
- the transport medium as such may for example comprise a gas or gas mixture of one or more (at room temperature and atmospheric pressure) noncombustible gases.
- the transport medium comprises at least 50% by volume nitrogen (chemical formula N2), and preferably at least 90% by volume nitrogen, for example at least 98% by volume or at least 99% by volume nitrogen.
- one or more other gases may be used in the transport medium (for example, an inert gas, argon and/or carbon dioxide).
- Different transport pressures can be applied in the transport network, for example usual transport pressures of natural gas in a natural gas network.
- a pressure prevailing in the transport network may, along at least a part of a fuel transport path, be higher than 5 bar, for example higher than 50 bar.
- the pressure in the transport network may be limited to a maximum pressure, for example using pressure limiting means, which will be clear to one skilled in the art.
- the transport medium is provided with a relatively small amount of hydrogen.
- the transport medium may for example be provided with at most 20% by volume hydrogen, and preferably at most 10% by volume hydrogen, for the purpose of the hydrogen transport.
- a second fuel for example methane and/or natural gas
- a filhng station as mentioned may for instance be configured to supply hydrogen (via one or more respective hydrogen dispensing devices) as well as to supply such a second fuel (via one or more respective hydrogen dispensing devices).
- a second fuel may for instance in itself be a fuel mixture which contains inter alia (molecular) hydrogen, besides other combustible gases such as, for example, fossil fuels (e.g. methane).
- the second fuel mentioned may furthermore be supplied, for example via the transport network, to other end users, for example central heating boilers of one or more buildings or the like.
- the above-mentioned separation of hydrogen from the second fuel, to supply such second fuel to respective end users may for example be such that this second fuel contains at most 35% by volume, and in particular at most 10% by volume hydrogen, for example at most 5% by volume (for example, at most 2% by volume).
- the transport medium is provided with a relatively large amount of hydrogen to be transported.
- the transport medium may for example be provided with at least 20% by volume hydrogen, and preferably at least 30% by volume hydrogen, for the purpose of hydrogen transport. This is for instance advantageous in the case of a relatively large demand for hydrogen in downstream parts of the network, for example if a relatively large number of filling stations need to be provided with hydrogen.
- the transport medium itself may comprise a second fuel as mentioned (for example, methane and/or natural gas and/or biogas), and in that case too, it may be advantageous when this second fuel is separated from the hydrogen, for supply to end users of this second fuel.
- the hydrogen separated from the transport medium is locally, temporarily, stored.
- downstream local storage of the hydrogen in particular at or near a filling station to be stocked, may be applied, in order that hydrogen is buffered to be able to effect continuous stocking of the filhng station.
- the hydrogen (to be buffered) is compressed to be stored locally under high pressure, for example a pressure of at least 100 bar or more, for example at least around 300 bar.
- the hydrogen is locally stored in several high pressure storage holders (for example gas cylinders).
- one or more hydrogen conduits may be provided in order for the locally stored hydrogen, in case of filling station hydrogen demand, to be discharged to the filling station for the purpose of refueling of end users.
- such holders may comprise gas holders disposed fixedly on and/or in a ground, in order that a relatively large storage volume can be provided.
- such holders in themselves can comprise mobile/displaceable gas holders (which are not fixed to/in a ground).
- a displaceable gas holder may for instance be a relatively hghtweight hydrogen transport holder, which is portable by, for example, just one or two persons, and/or which is displaceable using a handtruck.
- An example of such a separate gas holder is a loose gas cylinder.
- a displaceable (loose) hydrogen holder as mentioned can be used as a fuel tank for a transport means as mentioned.
- the transport means may be configured to receive one or more hydrogen-filled hydrogen holders, preferably in a stable position, and then, with the holder(s) in place, to move away with utilization of (dispensing of) hydrogen contained in the holder(s).
- the invention provides a system for transport of hydrogen, for example configured for carrying out a method according to the invention, the system comprising:
- At least one transport medium source which is configured to be connected to the network to supply a transport medium to the transport line;
- -at least one hydrogen source which is configured to be connected to the network, in particular downstream of the transport medium source, to supply hydrogen to the transport medium;
- -at least one hydrogen separation device which is configured to be connected to the network, downstream of the hydrogen source, the separation device being implemented to substantially remove hydrogen present in the transport medium from that medium;
- the system can transport hydrogen safely over relatively large distances, to provide downstream filling stations (for example for filling up of transport means) with hydrogen, without use of hydrogen trailers.
- the system comprises one or more local storage holders for storing the hydrogen separated from the transport medium.
- a holder can comprise, for example, a fixedly disposed (non-displaceable) holder for the purpose of local hydrogen delivery, or, for example, a holder that is displaceable for the purpose of hydrogen delivery elsewhere.
