従来、船舶においては駆動源の燃料として重油が広く用いられている（例えば、特許文献１参照）。特許文献１のように、燃料に重油が用いられている船舶はＣＯ２を多く排出するため、そのことが地球温暖化につながってしまう。そこで、環境保全の観点から、ＣＯ２の排出量を低減するため、駆動源の燃料に水素が用いられた船舶がある。この船舶には、主に水素ガスが充填された燃料充填容器によって水素が供給される。また、燃料充填容器への水素ガスの充填は、水素ステーションなどの水素充填施設で行われる。 Conventionally, heavy oil has been widely used as a fuel for a drive source in a ship (see, for example, Patent Document 1). As in Patent Document 1, ships that use heavy oil as fuel emit a large amount of CO 2 , which leads to global warming. Therefore, from the viewpoint of environmental protection, there are ships that use hydrogen as the fuel for the drive source in order to reduce CO 2 emissions. Hydrogen is supplied to this vessel mainly by a fuel filling container filled with hydrogen gas. Further, the filling of the fuel filling container with hydrogen gas is performed at a hydrogen filling facility such as a hydrogen station.

実施の形態．
図１は、実施の形態に係る水素供給システムに用いられる水素供給ユニット１００を模式的に示す斜視図である。 Embodiment.
FIG. 1 is a perspective view schematically showing a hydrogen supply unit 100 used in the hydrogen supply system according to the embodiment.

実施の形態に係る水素供給ユニット１００は、台車１０と、台車１０に積まれる荷台２０と、荷台２０に積まれる複数の燃料充填容器３０と、を備えている。水素供給ユニット１００は、トラックあるいはトレーラーなどの陸上輸送手段３００（後述する図２参照）を用いて輸送される。 The hydrogen supply unit 100 according to the embodiment includes a trolley 10, a loading platform 20 loaded on the trolley 10, and a plurality of fuel filling containers 30 loaded on the loading platform 20. The hydrogen supply unit 100 is transported by using a land transportation means 300 (see FIG. 2 described later) such as a truck or a trailer.

台車１０は、本体部１１と連結部１２と車輪１３とを備えている。本体部１１は平板形状を有し、上面に荷台２０が積まれるものである。連結部１２は本体部１１の前側に設けられ、陸上輸送手段３００に取り付けられるものである。車輪１３は本体部１１の下面に設けられ、陸上輸送手段３００によって連結部１２が引っ張られると回転して台車１０を動かすものである。また、本体部１１および連結部１２は、強度を持たせるため金属製である。 The carriage 10 includes a main body portion 11, a connecting portion 12, and wheels 13. The main body 11 has a flat plate shape, and the loading platform 20 is stacked on the upper surface. The connecting portion 12 is provided on the front side of the main body portion 11 and is attached to the land transportation means 300. The wheels 13 are provided on the lower surface of the main body portion 11 and rotate when the connecting portion 12 is pulled by the land transportation means 300 to move the carriage 10. Further, the main body portion 11 and the connecting portion 12 are made of metal in order to have strength.

荷台２０は、内部に複数の段が縦方向に形成された直方体形状を有しており、各段に複数の燃料充填容器３０が横向きで積まれるものである。また、荷台２０は、強度を持たせるため金属製である。また、荷台２０は、台車１０に例えば緊締装置（図示せず）でしっかりと固定されている。なお、荷台２０の形状は直方体形状に限定されず、複数の燃料充填容器３０を積める構造であれば他の形状でもよい。また、荷台２０は、各段に複数の燃料充填容器３０が横向きで積まれる構造に限定されず、内部に複数の段が横方向に形成され、各段に複数の燃料充填容器３０が縦向きで積まれる構造でもよい。 The loading platform 20 has a rectangular parallelepiped shape in which a plurality of stages are formed in the vertical direction, and a plurality of fuel filling containers 30 are stacked in each stage in a horizontal direction. Further, the loading platform 20 is made of metal in order to have strength. Further, the loading platform 20 is firmly fixed to the carriage 10 by, for example, a tightening device (not shown). The shape of the loading platform 20 is not limited to the rectangular parallelepiped shape, and may be any other shape as long as it has a structure in which a plurality of fuel filling containers 30 can be stacked. Further, the loading platform 20 is not limited to a structure in which a plurality of fuel filling containers 30 are stacked horizontally in each stage, and a plurality of stages are formed in the horizontal direction inside, and a plurality of fuel filling containers 30 are vertically oriented in each stage. It may be a structure that can be stacked with.

燃料充填容器３０は、燃料ガスを充填するものであり、燃料ガスには水素ガスが用いられている。水素ガスは、燃料充填容器３０内で圧縮されて貯蔵される。燃料充填容器３０は、円筒形状の円筒部３０ａとドーム形状のドーム部３０ｂとを有し、たとえば、アルミニウム合金またはプラスチックなどで構成されている。また、燃料充填容器３０のドーム部３０ｂには、燃料ガスを供給または充填するための配管が接続される燃料ガス供給バルブ３１が設けられている。 The fuel filling container 30 is for filling the fuel gas, and hydrogen gas is used as the fuel gas. The hydrogen gas is compressed and stored in the fuel filling container 30. The fuel filling container 30 has a cylindrical portion 30a having a cylindrical shape and a dome portion 30b having a dome shape, and is made of, for example, an aluminum alloy or plastic. Further, the dome portion 30b of the fuel filling container 30 is provided with a fuel gas supply valve 31 to which a pipe for supplying or filling the fuel gas is connected.

また、燃料充填容器３０は、少なくとも円筒部３０ａの外周にＣＦＲＰ（炭素繊維強化樹脂）が巻き付けられている。ＣＦＲＰ（炭素繊維強化樹脂）は、燃料充填容器３０の所要の耐圧性である機械的強度を向上させるために設けられている。燃料充填容器３０を上記の構成とすることで、所要の強度を確保しつつ、従来の燃料ガスを充填する鋼製容器などよりも軽量化することができる。また、燃料充填容器３０は、荷台２０に例えばベルト（図示せず）でしっかりと固定されている。 Further, in the fuel filling container 30, CFRP (carbon fiber reinforced resin) is wound around at least the outer periphery of the cylindrical portion 30a. CFRP (carbon fiber reinforced resin) is provided to improve the mechanical strength, which is the required pressure resistance of the fuel filling container 30. By having the fuel filling container 30 having the above configuration, it is possible to reduce the weight of the fuel filling container 30 as compared with a conventional steel container filled with fuel gas while ensuring the required strength. Further, the fuel filling container 30 is firmly fixed to the loading platform 20 by, for example, a belt (not shown).

水素供給ユニット１００は、公道を走る車両の一種であるため、道路運送車両法の規定により、車両を右側または左側に傾けていった場合に転倒しない最大の角度である最大安定傾斜角（転倒角度とも言う）が左右とも３５度以上である必要がある。そこで、各燃料充填容器３０は、水素供給ユニット１００の最大安定傾斜角が左右とも３５度以上となるように積まれている。例えば、各燃料充填容器３０は、荷台２０の各段において、縦横等間隔で同一方向に向けられて積まれている。各燃料充填容器３０をこのように積むことで、道路運送車両法の規定を満たすことができる。 Since the hydrogen supply unit 100 is a type of vehicle traveling on public roads, the maximum stable tilt angle (tilt angle) is the maximum angle at which the vehicle does not tip over when the vehicle is tilted to the right or left according to the provisions of the Road Transport Vehicle Law. Also called) must be 35 degrees or more on both sides. Therefore, each fuel filling container 30 is stacked so that the maximum stable inclination angle of the hydrogen supply unit 100 is 35 degrees or more on both the left and right sides. For example, each fuel filling container 30 is stacked in each stage of the loading platform 20 so as to be oriented in the same direction at equal intervals in the vertical and horizontal directions. By stacking the fuel filling containers 30 in this way, the provisions of the Road Transport Vehicle Law can be satisfied.

図２は、実施の形態に係る水素供給システムを示す模式図である。なお、図２では、水素供給ユニット１００を輸送する陸上輸送手段３００としてトラックを示しているが、それに限定されない。 FIG. 2 is a schematic diagram showing a hydrogen supply system according to an embodiment. Note that FIG. 2 shows a truck as a land transportation means 300 for transporting the hydrogen supply unit 100, but the present invention is not limited thereto.

図２に示すように、実施の形態に係る水素供給システムでは、３台以上の水素供給ユニット１００を備えている。各水素供給ユニット１００は、第一工程、第二工程、第三工程、第四工程を順番に繰り返す。 As shown in FIG. 2, the hydrogen supply system according to the embodiment includes three or more hydrogen supply units 100. Each hydrogen supply unit 100 repeats the first step, the second step, the third step, and the fourth step in order.

第一工程は、最初に、または後述する第四工程の後、水素ステーションなどの水素供給設備２００で水素供給ユニット１００に水素ガスの充填が行われる工程である。 The first step is a step in which the hydrogen supply unit 100 is filled with hydrogen gas in a hydrogen supply facility 200 such as a hydrogen station, first or after the fourth step described later.

第二工程は、第一工程の後、水素供給ユニット１００が陸上輸送手段３００によって、水素供給設備２００から駆動源の燃料に水素が用いられた船舶４００が停泊する港などの停泊場所５００に移動する工程である。 In the second step, after the first step, the hydrogen supply unit 100 is moved from the hydrogen supply facility 200 to a berth place 500 such as a port where a ship 400 using hydrogen as a driving source fuel is berthed by a land transportation means 300. It is a process to do.

第三工程は、第二工程の後、水素供給ユニット１００が、船舶４００に牽引により積み込まれ、駆動源に水素を供給した後、船舶４００から牽引により積み降ろされる工程である。なお、第三工程の積み込み時において、水素供給ユニット１００は、第二工程で用いられる陸上輸送手段３００によって牽引されてもよいし、それとは別の車両などの牽引手段によって牽引されてもよい。また、第三工程の積み下ろし時において、水素供給ユニット１００は、第四工程で用いられる陸上輸送手段３００によって牽引されてもよいし、それとは別の車両などの牽引手段によって牽引されてもよい。 The third step is a step in which the hydrogen supply unit 100 is towed onto the ship 400 after the second step, hydrogen is supplied to the drive source, and then the hydrogen supply unit 100 is towed and unloaded from the ship 400. At the time of loading in the third step, the hydrogen supply unit 100 may be towed by the land transportation means 300 used in the second step, or may be towed by a towing means such as another vehicle. Further, at the time of loading and unloading in the third step, the hydrogen supply unit 100 may be towed by the land transportation means 300 used in the fourth step, or may be towed by a towing means such as another vehicle.

第四工程は、第三工程の後、水素供給ユニット１００が陸上輸送手段３００によって、停泊場所５００から水素供給設備２００に移動する工程である。 The fourth step is a step in which the hydrogen supply unit 100 is moved from the berth place 500 to the hydrogen supply facility 200 by the land transportation means 300 after the third step.

そして、少なくとも３台の水素供給ユニット１００は、同時刻においてそれぞれ異なる工程を行う。 Then, at least three hydrogen supply units 100 perform different steps at the same time.

なお、３台の水素供給ユニット１００を、それぞれ第一の水素供給ユニット１００ａ、第二の水素供給ユニット１００ｂ、第三の水素供給ユニット１００ｃと称する場合、例えば、第一の水素供給ユニット１００ａが、第一工程を行っているとき、第二の水素供給ユニット１００ｂは、第三工程を行っており、第三の水素供給ユニット１００ｃは、第二工程または第四工程を行っている。 When the three hydrogen supply units 100 are referred to as a first hydrogen supply unit 100a, a second hydrogen supply unit 100b, and a third hydrogen supply unit 100c, for example, the first hydrogen supply unit 100a When the first step is performed, the second hydrogen supply unit 100b is performing the third step, and the third hydrogen supply unit 100c is performing the second step or the fourth step.

そして、船舶４００に積まれた第二の水素供給ユニット１００ｂは、駆動源に水素を供給して燃料充填容器３０内が空になった後、船舶４００が停泊場所５００に停まったタイミングで船舶４００から積み下ろされる。また、陸上輸送手段３００によって水素供給設備２００から運ばれてきた、燃料充填容器３０内に水素が充填されている第三の水素供給ユニット１００ｃは、船舶４００に積み込まれる。また、第一の水素供給ユニット１００ａは、水素供給設備２００で水素ガスの充填が行われる。 Then, the second hydrogen supply unit 100b loaded on the ship 400 supplies hydrogen to the drive source to empty the fuel filling container 30, and then the ship 400 stops at the berth place 500. Unloaded from 400. Further, the third hydrogen supply unit 100c, which is carried from the hydrogen supply facility 200 by the land transportation means 300 and is filled with hydrogen in the fuel filling container 30, is loaded on the ship 400. Further, the first hydrogen supply unit 100a is filled with hydrogen gas in the hydrogen supply facility 200.

ここで、従来、船舶４００から燃料充填容器３０を積み下ろす際、および、船舶４００に燃料充填容器３０を積み込む際には、船舶４００または停泊場所５００に設置されたクレーンなどの装置を用いて燃料充填容器３０を持ち上げる必要があった。そのため、設備コストおよび手間がかかっていた。 Here, conventionally, when loading and unloading the fuel filling container 30 from the ship 400 and when loading the fuel filling container 30 into the ship 400, fuel is used by using a device such as a crane installed in the ship 400 or the berthing place 500. It was necessary to lift the filling container 30. Therefore, equipment cost and labor are required.

しかし、実施の形態に係る水素供給ユニット１００は、複数の燃料充填容器３０が積まれた荷台２０と台車１０とが一体となった構成である。また、燃料充填容器３０に貯蔵される燃料は水素であり従来の水素以外の燃料よりも軽く、燃料充填容器３０自体も従来の燃料ガスを充填する鋼製容器などよりも軽い。 However, the hydrogen supply unit 100 according to the embodiment has a configuration in which a loading platform 20 on which a plurality of fuel filling containers 30 are loaded and a carriage 10 are integrated. Further, the fuel stored in the fuel filling container 30 is hydrogen, which is lighter than the conventional fuel other than hydrogen, and the fuel filling container 30 itself is also lighter than the conventional steel container filled with fuel gas.

そのため、従来に比べて水素供給ユニット１００を軽量化することができる。その結果、水素供給ユニット１００を牽引して、船舶４００からの燃料充填容器３０の積み下ろし、および、船舶４００への燃料充填容器３０の積み込みを容易に行うことができるため、クレーンなどの装置が不要となる。そのため、設備コストを削減でき、手間も省くことができる。 Therefore, the weight of the hydrogen supply unit 100 can be reduced as compared with the conventional case. As a result, the hydrogen supply unit 100 can be towed to easily load and unload the fuel filling container 30 from the ship 400 and load the fuel filling container 30 into the ship 400, so that no device such as a crane is required. Will be. Therefore, the equipment cost can be reduced and the labor can be saved.

さらに、実施の形態では、水素供給ユニット１００を軽量化することができるため、重心の位置が下がる。そのため、水素供給ユニット１００の最大安定傾斜角を大きくすることができ、道路運送車両法の規定による制約を受けづらくなるので、燃料充填容器３０の搭載量を増やすことができる。さらに、実施の形態では、水素供給ユニット１００を軽量化することができるため、船舶４００に積まれている時の復元力、つまり波で傾いても元の位置に戻る力への悪影響を少なくすることができる。 Further, in the embodiment, the weight of the hydrogen supply unit 100 can be reduced, so that the position of the center of gravity is lowered. Therefore, the maximum stable inclination angle of the hydrogen supply unit 100 can be increased, and the restrictions imposed by the provisions of the Road Transport Vehicle Law are less likely to be imposed, so that the loading capacity of the fuel filling container 30 can be increased. Further, in the embodiment, the weight of the hydrogen supply unit 100 can be reduced, so that the restoring force when the hydrogen supply unit 100 is loaded on the ship 400, that is, the force of returning to the original position even if tilted by a wave is reduced. be able to.

また、船舶４００から積み下ろされた第二の水素供給ユニット１００ｂは、陸上輸送手段３００によって水素供給設備２００に運ばれ、水素供給設備２００で水素ガスの充填が行われる。また、船舶４００に積み込まれた第三の水素供給ユニット１００ｃは、船舶４００の駆動源に水素を供給する。また、水素供給設備２００で水素ガスの充填が行われた第一の水素供給ユニット１００ａは、船舶４００が停泊する停泊場所５００に運ばれる。 Further, the second hydrogen supply unit 100b loaded and unloaded from the ship 400 is carried to the hydrogen supply facility 200 by the land transportation means 300, and the hydrogen gas is filled in the hydrogen supply facility 200. Further, the third hydrogen supply unit 100c loaded on the ship 400 supplies hydrogen to the drive source of the ship 400. Further, the first hydrogen supply unit 100a filled with hydrogen gas in the hydrogen supply facility 200 is carried to the berth place 500 where the ship 400 is berthed.

ここで、従来、燃料充填容器３０への水素の供給が行われる水素ステーションなどの水素供給設備２００の数は全国的に少なく、船舶４００が停泊する停泊場所５００の位置によっては、停泊場所５００と水素供給設備２００との距離が遠く、燃料充填容器３０の輸送に時間がかかる。そのため、船舶４００に燃料充填容器３０を積み込むまでの待ち時間がかかり、船舶４００への水素ガスの供給に時間がかかっていた。 Here, conventionally, the number of hydrogen supply facilities 200 such as hydrogen stations that supply hydrogen to the fuel filling container 30 is small nationwide, and depending on the position of the berth place 500 where the ship 400 berths, the berth place 500 may be used. The distance from the hydrogen supply facility 200 is long, and it takes time to transport the fuel filling container 30. Therefore, it takes a long time to load the fuel filling container 30 into the ship 400, and it takes time to supply hydrogen gas to the ship 400.

しかし、実施の形態に係る水素供給システムでは、３台以上の水素供給ユニット１００を備えており、そのうち少なくとも３台の水素供給ユニット１００は、同時刻においてそれぞれ異なる工程を行う。そのため、船舶４００に燃料充填容器３０を積み込むまでの待ち時間を短縮でき、船舶４００への水素ガスの供給にかかる時間を短縮することができる。 However, the hydrogen supply system according to the embodiment includes three or more hydrogen supply units 100, of which at least three hydrogen supply units 100 perform different steps at the same time. Therefore, the waiting time until the fuel filling container 30 is loaded on the ship 400 can be shortened, and the time required for supplying the hydrogen gas to the ship 400 can be shortened.

また、船舶４００が停泊する停泊場所５００に水素ステーションなどの水素供給設備２００を新たに設置する必要がなく、既存の水素供給設備を使用することができるため、設備コストを抑制することができる。また、船舶４００の数が増えても水素供給ユニット１００の数を増やせばよいため、拡張性が高い。 Further, since it is not necessary to newly install a hydrogen supply facility 200 such as a hydrogen station at the berth place 500 where the ship 400 berths, the existing hydrogen supply facility can be used, so that the equipment cost can be suppressed. Further, even if the number of ships 400 increases, the number of hydrogen supply units 100 may be increased, so that the expandability is high.

図３は、実施の形態に係る水素供給システムに用いられる水素供給ユニット１００の船舶４００を模式的に示す平面図である。 FIG. 3 is a plan view schematically showing the ship 400 of the hydrogen supply unit 100 used in the hydrogen supply system according to the embodiment.

図３に示すように、水素供給ユニット１００は、船舶４００の後部に形成された積載スペース４１０に積載される。この積載スペース４１０は、駆動源および座席などの船舶４００の既存の設備と競合しない位置に形成されている。 As shown in FIG. 3, the hydrogen supply unit 100 is loaded in the loading space 410 formed at the rear of the ship 400. The loading space 410 is formed in a position that does not compete with the existing equipment of the ship 400 such as a drive source and a seat.

このように、水素供給ユニット１００の積載スペース４１０を船舶４００の後部に形成することで、船舶４００から燃料充填容器３０の積み下ろし、および、船舶４００への燃料充填容器３０の積み込みを行いやすくすることができる。また、積載スペース４１０は、駆動源および座席などの船舶４００の既存の設備と競合しない位置に形成されているため、積載スペース４１０を形成するために既存の設備を移動させるおよび撤去する必要がなく、既存のスペースを有効利用することができる。 By forming the loading space 410 of the hydrogen supply unit 100 at the rear of the ship 400 in this way, it is possible to easily load and unload the fuel filling container 30 from the ship 400 and load the fuel filling container 30 into the ship 400. Can be done. Further, since the loading space 410 is formed at a position that does not compete with the existing equipment of the ship 400 such as the drive source and the seat, it is not necessary to move and remove the existing equipment in order to form the loading space 410. , The existing space can be used effectively.

図４は、実施の形態に係る水素供給システムに用いられる水素供給ユニット１００の船舶４００への水素供給方法を説明する図である。 FIG. 4 is a diagram illustrating a method of supplying hydrogen to the ship 400 of the hydrogen supply unit 100 used in the hydrogen supply system according to the embodiment.

まず、各燃料充填容器３０の燃料ガス供給バルブ３１に、集合配管４２１の一方（以下、分岐側と称する）の端部４２２を接続する。そして、集合配管４２１のもう一方（以下、集合側と称する）の端部４２３を船舶４００に設けられている接続配管４２４の燃料側配管４２５に接続する。この接続配管４２４の駆動側配管４２６には、延長ホース４３２を介して船舶４００の駆動源が接続されている。 First, the end portion 422 of one of the collecting pipes 421 (hereinafter referred to as a branch side) is connected to the fuel gas supply valve 31 of each fuel filling container 30. Then, the other end 423 of the collecting pipe 421 (hereinafter referred to as the collecting side) is connected to the fuel side pipe 425 of the connecting pipe 424 provided in the ship 400. The drive source of the ship 400 is connected to the drive-side pipe 426 of the connection pipe 424 via an extension hose 432.

なお、接続配管４２４の燃料側配管４２５は複数設けられており、燃料側配管４２５のそれぞれに集合配管４２１の集合側の端部４２３が接続される。つまり、接続配管４２４には、複数の集合配管４２１が接続される。 A plurality of fuel-side pipes 425 of the connection pipe 424 are provided, and an end portion 423 of the collective pipe 421 on the collective side is connected to each of the fuel-side pipes 425. That is, a plurality of collective pipes 421 are connected to the connection pipe 424.

接続配管４２４の駆動側配管４２６には、開閉により配管内の水素ガスの流れを許容または遮断する第一開閉弁４２８が設けられている。さらに、接続配管４２４の駆動側配管４２６の第一開閉弁４２８よりも駆動源側には、燃料充填容器３０内の高圧の水素ガスを減圧させる減圧弁４２７が設けられている。 The drive-side pipe 426 of the connection pipe 424 is provided with a first on-off valve 428 that allows or shuts off the flow of hydrogen gas in the pipe by opening and closing. Further, a pressure reducing valve 427 for reducing the pressure of high-pressure hydrogen gas in the fuel filling container 30 is provided on the drive source side of the drive side pipe 426 of the connection pipe 424 with respect to the first on-off valve 428.

接続配管４２４の燃料側配管４２５には、開閉により配管内の水素ガスの流れを許容または遮断する第二開閉弁４２９がそれぞれ設けられている。また、接続配管４２４の燃料側配管４２５には、配管内の水素ガスの圧力を検知する圧力計４３０がそれぞれ設けられている。また、接続配管４２４には、異常時に開放して水素ガスを外部に放出するための安全弁４３１が設けられている。 The fuel side pipe 425 of the connection pipe 424 is provided with a second on-off valve 429 that allows or shuts off the flow of hydrogen gas in the pipe by opening and closing. Further, the fuel side pipe 425 of the connection pipe 424 is provided with a pressure gauge 430 for detecting the pressure of hydrogen gas in the pipe. Further, the connection pipe 424 is provided with a safety valve 431 for opening the connection pipe 424 and releasing hydrogen gas to the outside in the event of an abnormality.

そして、第一開閉弁４２８および第二開閉弁４２９を開状態にして、減圧弁４２７を開状態にすることで、燃料充填容器３０内の高圧の水素ガスが減圧弁４２７で減圧されて、船舶４００の駆動源に供給される。なお、減圧弁４２７は、圧力計４３０が検知する圧力に基づいて所定の開度に制御される。そうすることで、所定の圧力の水素ガスを船舶４００の駆動源に供給することができる。 Then, by opening the first on-off valve 428 and the second on-off valve 429 and opening the pressure reducing valve 427, the high-pressure hydrogen gas in the fuel filling container 30 is decompressed by the pressure reducing valve 427, and the ship is shipped. It is supplied to 400 drive sources. The pressure reducing valve 427 is controlled to a predetermined opening degree based on the pressure detected by the pressure gauge 430. By doing so, hydrogen gas having a predetermined pressure can be supplied to the drive source of the ship 400.

以上、実施の形態に係る水素供給システムは、陸上輸送手段３００に連結される台車１０と、台車１０に積まれる荷台２０と、荷台２０に積まれ、水素が充填される複数の燃料充填容器３０と、を有し、水素供給設備２００で燃料充填容器３０に水素ガスの充填が行われる第一工程と、第一工程の後、駆動源の燃料に水素が用いられた船舶４００が停泊する停泊場所５００に陸上輸送手段３００によって移動する第二工程と、第二工程の後、船舶４００に牽引により積み込まれ、駆動源に燃料充填容器３０の水素を供給した後、船舶４００から牽引により積み降ろされる第三工程と、第三工程の後、水素供給設備２００に陸上輸送手段３００によって移動する第四工程と、を繰り返す水素供給ユニット１００を３台以上備え、少なくとも３台の水素供給ユニット１００は、同時刻においてそれぞれ異なる工程を行うものである。 As described above, the hydrogen supply system according to the embodiment includes a trolley 10 connected to the land transportation means 300, a loading platform 20 loaded on the trolley 10, and a plurality of fuel filling containers 30 loaded on the loading platform 20 and filled with hydrogen.

A first step in which three or more hydrogen supply units 100 having a fuel filling container 30 and three or more hydrogen supply units 100 are provided, and each hydrogen supply unit 100 fills the fuel filling container 30 with hydrogen gas in the hydrogen supply facility 200, and the first step. After the process, the second step is to move the ship 400 using hydrogen as the fuel of the drive source to the berth place 500 where the ship 400 is anchored by the land transportation means 300, and after the second step, the ship 400 is loaded and driven by traction.

At least three hydrogen supply units 100 perform different steps at the same time. Therefore, the waiting time until the fuel filling container 30 is loaded on the ship 400 can be shortened, and the hydrogen gas can be smoothly supplied to the ship 400.

また、実施の形態に係る水素供給システムによれば、水素供給ユニット１００は、複数の燃料充填容器３０が積まれた荷台２０と台車１０とが一体となった構成である。さらに、燃料充填容器３０に貯蔵される燃料は水素であり従来の水素以外の燃料よりも軽く、燃料充填容器３０自体も従来の燃料ガスを充填する鋼製容器などよりも軽い。 Further, according to the hydrogen supply system according to the embodiment, the hydrogen supply unit 100 has a configuration in which a loading platform 20 on which a plurality of fuel filling containers 30 are loaded and a carriage 10 are integrated. Further, the fuel stored in the fuel filling container 30 is hydrogen, which is lighter than the conventional fuel other than hydrogen, and the fuel filling container 30 itself is also lighter than the conventional steel container filled with the fuel gas.

そのため、従来に比べて水素供給ユニット１００を軽量化することができる。その結果、水素供給ユニット１００を牽引して、船舶４００からの燃料充填容器３０の積み下ろし、および、船舶４００への燃料充填容器３０の積み込みを容易に行うことができるため、クレーンなどの装置が不要となる。そのため、設備コストを削減でき、手間も省くことができる。 Therefore, the weight of the hydrogen supply unit 100 can be reduced as compared with the conventional case. As a result, the hydrogen supply unit 100 can be towed to easily load and unload the fuel filling container 30 from the ship 400 and load the fuel filling container 30 into the ship 400, so that no device such as a crane is required.

There is. Therefore, the fuel filling container 30 can be made lighter than a conventional steel container filled with fuel gas while ensuring the required strength. Since the hydrogen supply unit 100 can be made lighter, the position of the center of gravity can be lowered and the maximum stable inclination angle can be increased. Therefore, it is difficult to be restricted by the provisions of the Road Transport Vehicle Law, and the amount of the fuel filling container 30 to be loaded can be increased. Further, since the hydrogen supply unit 100 can be reduced in weight, it is possible to reduce the adverse effect on the restoring force when the hydrogen supply unit 100 is loaded on the ship 400.
