[0008]  [0008]
水素の製造においては、 前記した特許文献 1に記載されたメガフ ロートの構造では、 製造した液体水素が非常に軽い （比重 <く 1 ) ために水素貯蔵部とそれ以外の部分の構造が持つ重量とがアンパラ ンスになることが想定される。 即ち、 水素貯蔵部をメガフロー トの下部に配備すると液体水素 貯蔵部が軽いために、 液体水素生産装置全体が不安定 （重心 が高くなるために） になり、 また、 液体水素貯蔵装置部をメガフ ロートの上部に配備すると風車、 太陽電池パネルなど電気工ネル ギーを得る部分の面積が相対的に狭くなること、 が想定される。 —方、 メガフロートの側面に配備するとメガフロートに打ち寄せ る波が遮られてしまい、 波力エネルギーを利用できない課題、 が ある。 In the production of hydrogen, the structure of the megafloat described in the above-mentioned Patent Document 1 is such that the liquid hydrogen produced is very light (specific gravity <1), so the weight of the structure of the hydrogen storage part and the other parts. Are assumed to be unbalanced. In other words, if the hydrogen storage unit is placed at the bottom of the mega float, the liquid hydrogen storage unit is light and the entire liquid hydrogen production device becomes unstable (because the center of gravity is high). If it is installed on the upper part of the funnel, it is assumed that the area for obtaining electrical energy, such as windmills and solar panels, will be relatively narrow. -On the other hand, if it is deployed on the side of the mega float, the wave that hits the mega float is blocked, and there is a problem that wave energy cannot be used.

また、 前記非特許文献 1に記載のように、 通常の電気分解法で液 体水素を製造する時には、 電気分解に必要な電気エネルギーを大 量に必要とするので前記自然エネルギーで得た電気エネルギーを そのために相当量を消費するために、 全体として経済的に液体 水素を製造できない大きい課題、 があった。  In addition, as described in Non-Patent Document 1, when liquid hydrogen is produced by a normal electrolysis method, a large amount of electric energy necessary for electrolysis is required, so that the electric energy obtained from the natural energy is obtained. For this reason, since a considerable amount was consumed, there was a big problem that liquid hydrogen could not be produced economically as a whole.
[0010]  [0010]
更に、 製造した水素を液体水素のままでは製造 ·貯蔵する場所から 消費する場所まで経済的且安全に運搬できない （液揺動 （スロッシ ング）） 大きな課題がある。  Furthermore, there is a big problem that the produced hydrogen cannot be transported economically and safely from the place where it is produced and stored to the place where it is consumed if it is liquid hydrogen (liquid throttling).
[0011〕  [0011]
即ち、 非特許文献 1に記载のように液体水素の形で水素を装置  That is, as described in Non-Patent Document 1, hydrogen is supplied in the form of liquid hydrogen.
(水素貯蔵タンク） に貯蔵'運搬する時の最大の課題は、 液体水素 が蒸発して装置から漏洩しやすい （ボイルオフ） ことと、 水素貯 蔵タンクを搭載した例えば水素貯蔵タンク運搬船が揺れ動く こと によって生じる液体水素の液揺動 （スロッシング） により水素 貯蔵タンクが爆発を生じ易くなり危険になること、 である。  The biggest challenges when storing and transporting to (hydrogen storage tanks) are that liquid hydrogen is likely to evaporate and leak from the equipment (boil-off) and that a hydrogen storage tank carrier equipped with a hydrogen storage tank swings. The liquid storage tank is likely to explode due to liquid sloshing (sloshing), making it dangerous.
[0012]  [0012]
次に非特許文献 1における水素エンジン （レシプロ式） では、 通常 のガソリンと同じエンジンを利用できる利点はあるが、 ビス トン の往復運動を用いているために水素の燃焼を動力に変換する利用 効率が低い大きな課題、 があった。  Next, the hydrogen engine (reciprocating type) in Non-Patent Document 1 has the advantage of being able to use the same engine as ordinary gasoline, but because it uses the reciprocating motion of Biston, the efficiency of converting hydrogen combustion into power is efficient. There was a big problem,

次に非特許文献 1における燃料電池においては、 変換する利用効率 が低く長期的信頼性が低く、 電極などに白金などの貴金属を使用 する為に非常に高価になる経済性の点で大きな課題、 があった。 課題を解決するための手段  Next, in the fuel cell in Non-Patent Document 1, the conversion efficiency is low, the long-term reliability is low, and the use of precious metals such as platinum for electrodes is a major issue in terms of economy, was there.

次に、 本発明の第一の実施形態を第 1図、 第 2図を用いて説明 する。  Next, a first embodiment of the present invention will be described with reference to FIG. 1 and FIG.
第 1図は、 本発明による水素生産 ·貯蔵'運搬する方法 ·装置並び に第一の水素供給基地 （以下単に水素供給基地と称する） の概念 断面図である。 第 2図は第 1図の一部である水素貯蔵格納部とメ ガブロート並びに運搬船との関係を示す概念断面図である。  FIG. 1 is a conceptual cross-sectional view of a hydrogen production / storage / transport method / equipment and a first hydrogen supply base (hereinafter simply referred to as a hydrogen supply base) according to the present invention. FIG. 2 is a conceptual cross-sectional view showing the relationship between the hydrogen storage and storage unit, the mega bloat, and the transport ship, which are a part of FIG.
第 1図において、 水素供給基地は大別してメガフロート 3 0と水 素貯蔵タンク格納部 4 0から構成される。 水素貯蔵タンク格納部 In FIG. 1, the hydrogen supply base is roughly divided into a mega float 30 and a hydrogen storage tank storage 40. Hydrogen storage tank storage
4 0には例えば実施例 2で説明する水素貯蔵タンク 0 1が収納さ れている。 第 1図においてメガフロー ト 3 0の上面には風車 3 1 及ぴ太陽光発電パネル 3 2が設置されている。 For example, a hydrogen storage tank 01 described in Example 2 is stored in 40. In FIG. 1, a wind turbine 3 1 and a photovoltaic power generation panel 3 2 are installed on the upper surface of the mega float 30.
風力による発電は風車 3 1 とそれに接続された発電機 3 1 Cでな され、 そこで得た電力は風車を支持する支柱 3 1 A内の電気配線 と電気配線 3 5 Aを経由して電源装置 3 8に送られる。  Wind power is generated by the wind turbine 3 1 and the generator 31 1 C connected to the wind turbine 3 1 C, and the power obtained there is a power supply unit via the electrical wiring and electrical wiring 3 1 A in the column 3 1 A that supports the wind turbine. 3 Sent to 8.

[0025]  [0025]
電源装置 1 8に蓄えられた電力を利用して、 海水を電気分解装置 4 1で電気分解してまず液体水素を製造する。 液体酸素も同時に 製造できるが本願の主題でないので説明しない。 液体水素の製造 には、 水面下 1 0〜 2 0 0 0 mの海中に置かれた電気分解装置 4 1において海水圧のポテンシャルを利用して海水を約 2〜 2 0 0 気圧に加圧する。  First, liquid hydrogen is produced by electrolyzing seawater with the electrolyzer 4 1 using the power stored in the power supply 1 8. Although liquid oxygen can be produced at the same time, it will not be described because it is not the subject of this application. In the production of liquid hydrogen, seawater is pressurized to about 2 to 200 atmospheres using the potential of seawater pressure in an electrolyzer 41 placed in the sea 10 to 200 meters below the surface of the water.
電気分解装置 4 1 の電極近傍だけを、 例えば遠隔操作で加熱ヒー タで海水を温めつつ、 メガフロート 3 0から例えば K O Hのよ う なアルカリ物質を電極近傍に流し込み海水の電気分解を行う。 電 気分解によって生成した 2〜 2 0 0気圧の気体水素が電気分解装 置 4 1 の周囲に設置された例えば断熱膨張装置（図示していなレ、） によって、 冷却されて液体水素となる。  The seawater is electrolyzed by pouring an alkaline substance such as KOH from the mega float 30 into the vicinity of the electrode while warming the seawater with a heating heater, for example, by remote control only in the vicinity of the electrode of the electrolyzer 41. The gaseous hydrogen of 2 to 200 atm generated by electrolysis is cooled to liquid hydrogen by, for example, an adiabatic expansion device (not shown) installed around the electrolysis device 4 1.
液体水素はハッチ 4 2を通って、 例えば実施例 2に述べる水素貯 蔵タンク 0 1に充填される。  The liquid hydrogen passes through the hatch 42 and is filled into the hydrogen storage tank 01 described in Example 2, for example.
実施例 2で記載のように、 充填された液体水素はその後で 水素貯蔵タンク 0 1が徐徐に近傍の海水温度とほぼ等しい温度に 上がっても液状の状態を保って水素貯蔵タンク 0 1 にそのまま貯 蔵される。 As described in Example 2, the filled liquid hydrogen is then Even if the hydrogen storage tank 01 gradually rises to a temperature approximately equal to the temperature of the seawater nearby, it remains in a liquid state and is stored in the hydrogen storage tank 0 1 as it is.
[0026]  [0026]
電気分解装置 4 1はその下面に設置した碇 4 4にワイヤー 4 3を 経由して海中に係留される。  The electrolyzer 4 1 is moored in the sea via wires 4 3 on the pit 4 4 installed on the lower surface.
[0027]  [0027]
メガフロート 3 0においては司令塔 5 0があり、 ここから各種の 制御指示を出す。 例えば、 後記するように水素貯蔵タンク格納部 4 0をメガフロート 3 0から切り離す指令、水素貯蔵タンク格納 部 4 0の制御部 4 0 Cに水素を保冷する条件や 4 0の海中にお ける位置の指令、運搬船 5 5に近接する時に碇 4 4 Λを上げる指 令、 電気分解装置 4 1に電力ならびに特殊部材 （電気分解を促進 する部材例えば K O H ) をパイプ 5 4から供給する指令、 水素貯 蔵タンク格納部 4 0 とメガフロート 3 0 との間での空の水素貯 蔵タンク 0 1 Aや水素を充填したタンク 0 1の自動搬送、ハッチ 4 2 , 5 2の開閉、 などを有線、 無線及びもしくは超音波の手段 で指令する。  Megafloat 30 has a control tower 50, from which various control instructions are issued. For example, as described later, a command to disconnect the hydrogen storage tank storage 40 from the mega float 30, a control condition of the hydrogen storage tank storage 40, the condition for keeping hydrogen in 40C, and the position of 40 in the sea Directive to raise 碇 4 4 Λ when approaching carrier 5 5, directive to supply power and special parts (members that promote electrolysis, such as KOH) to pipe 4 4, hydrogen storage, Empty hydrogen storage tank between storage tank storage section 40 and mega float 30 0 0 1 A or hydrogen-filled tank 0 1 Automatic transfer, opening / closing hatch 4 2, 5 2, etc. Command by radio and / or ultrasonic means.

水素貯蔵タンク格納部 4 0 とメガフロー ト 3 0を切り離す理由 は次に述べる通りである。 即ち、 水素貯蔵タンク格納部 4 0 の容積がメガフロート 3 0のそれより もはるかに大きくなるた めに、 1台のメガフロート 3 0に対して複数の水素貯蔵タンク 格納部 4 0を置いた方が経済的であることと水素貯蔵タンク格 納部 4 0を海中例えば 1 0 0 m以上深い海中に置く ことに よって海水の温度が約 5度、 海水圧が 1 0気圧以上と低温加圧 状態であり且つそれらの値が年中ほぼ一定であるので貯蔵に必 要な電力他のコス トを軽減できて経済的に水素を貯蔵できる、 からである。  The reason for separating the hydrogen storage tank storage 40 and the mega float 30 is as follows. That is, because the volume of the hydrogen storage tank storage 40 is much larger than that of the mega float 30, a plurality of hydrogen storage tank storage 40 are placed for one mega float 30. By placing the hydrogen storage tank storage section 40 in the sea, for example, at a depth of more than 100 m, the seawater temperature is about 5 degrees and the seawater pressure is over 10 atmospheres. This is because they are in a state and their values are almost constant throughout the year, so that power and other costs required for storage can be reduced, and hydrogen can be stored economically.

本実施例の要点をここでまとめておく と以下の通りである。 The main points of the present embodiment are summarized as follows.
( 1 ) 太陽光、 風力、 波力の自然エネルギーに加えて、 海水の深さが 1 0 m以上で望ましくは 2 0 0 0 m以下の海水圧のポテンシャル エネルギーを活用することで、 経済的な水素の製造 （生成） が 出来ること。 (1) In addition to the natural energy of sunlight, wind power, and wave power, it is economical by utilizing the potential energy of seawater pressure with a seawater depth of 10 m or more and preferably 200 m or less. Able to produce (generate) hydrogen.
( 2 ) 実施例 2で述べる例えばタケ炭を水素貯蔵材として利用した 結果、 液体水素の状態で充填した後は温度が充填時の温度より 上がっても貯蔵された水素は液状の状態をそのまま保つので長期 間貯蔵 (保持)できること。 (2) As a result of using, for example, bamboo charcoal described in Example 2 as a hydrogen storage material, after filling in the state of liquid hydrogen, the temperature is higher than the temperature at the time of filling. Even if it goes up, the stored hydrogen will remain in a liquid state, so it can be stored (held) for a long time.
すなわち、 ボイルオフの課題を大幅に低減できること。  In other words, the boil-off problem can be greatly reduced.
( 3 ) 実施例 2で述べる例えばタケ炭を水素貯蔵材として利用した結果 、 水素タンク 0 1に相当する液体水素がそのまま充填された水 素貯蔵タンク 0 1を運搬船 5 5で海上を水素生成の場所と異なる水 素消費の場所に運搬する際に、 たとえば運搬船が揺れ動くために 発生して極めて危険な液揺動（ス口ッシング）の課題を解決できる こと。  (3) As a result of using, for example, bamboo charcoal described in Example 2 as a hydrogen storage material, hydrogen storage tank 0 1 filled with liquid hydrogen corresponding to hydrogen tank 0 1 as it is is used to generate hydrogen on the sea with transport ship 5 5 When transporting to a place where hydrogen is consumed differently from the place, for example, the problem of liquid swinging (squishing) that occurs due to the swinging of the transport ship can be solved.
なお、 （ 1 ) で海水の深さが 1 0 m以上である主な理由は、 それ より も浅いと電気分解装置 4 1を遠隔操作で操作することに 要する費用に対して得られる効果が小さいこと、 2 0 0 0 m以下 が望ましいとした主な理由はそれより も深い海中に設置すること に伴う技術面の困難性による。  In (1), the main reason why the depth of seawater is 10 m or more is that if it is shallower than that, the effect obtained for the cost of operating the electrolyzer 41 remotely is small. The main reason why it is desirable to have a length of 200 m or less is due to technical difficulties associated with installation in the deeper sea.
また、 運搬手段としては上記した運搬船 5 5の他に飛行機、 パイプによる水素の直接輸送も可能である。 第一の水素供給基地 が陸地から離れている、 例えば 1 0 0 k m以上では水素の比重、 水素貯蔵装置 0 1のサイズ、 重さを勘案すると運搬船 5 5による 輸送が最適である。  As a means of transportation, in addition to the above-mentioned transport ship 55, hydrogen can also be transported directly by airplane or pipe. When the first hydrogen supply base is far from the land, for example, 100 km or more, transport by carrier 5 5 is optimal considering the specific gravity of hydrogen, the size and weight of hydrogen storage device 01.

本発明のよ うにメガフロート 3 0を利用する場合は、 風車の支 柱 3 1 Aは地上用風力発電より も低い支柱でよい。 しかし、 風を 効率よく捉え、メガフロート上の設備や作業員の安全性を考慮し、 羽根の長さを 1 5 mとすると、風車の支柱 3 1 Aの高さはその長 さプラス 5 m程度つまり 2 0 m以上である。 したがって、 支柱 3 When the mega float 30 is used as in the present invention, the pillar 31 1 A of the wind turbine may be a lower support than the ground wind power generation. However, if the wind is captured efficiently and the safety of the equipment and workers on the megafloat is taken into account, and the blade length is 15 m, the height of the wind turbine support 3 1 A is the length plus 5 m. The degree, that is, 20 m or more. Therefore, prop 3
1 Aに補強を設けることにより、風車の支柱 3 1 Aそれ自体の強 度をある程度低く し、 コス トを削減することができる。 By providing reinforcement to 1A, the strength of the wind turbine support 3 1A itself can be lowered to some extent, and costs can be reduced.
[0032]  [0032]
以上説明した第一の水素供給基地において、 風力、 太陽電池、 波 力の自然エネルギーと海水の持つ海水圧ポテンシャルエネルギー の利用を全て一緒で行う必要は必ずしもない。  In the first hydrogen supply base explained above, it is not always necessary to use wind energy, solar cells, wave natural energy and seawater pressure potential energy all together.
また図示はしていないが、 風車 3 1 を補強するためにネッ ト状 のワイヤを張って支柱 3 1 Aを結わえても良い。  Although not shown, in order to reinforce the wind turbine 3 1, a net-like wire may be stretched to connect the support post 3 1 A.
この実施例によれば、 メガフロート 3 0の上面、 下面、 周囲及び メガフロート 3 0自体の容積を有効に利用することができる効果 力 Sある。  According to this embodiment, there is an effect S that can effectively use the upper surface, the lower surface, the periphery of the mega float 30 and the volume of the mega float 30 itself.
更に、 電気分解した水素を冷却するエネルギーの相当部分はー且 液体水素まで冷やして水素を充填した該水素貯蔵タンク 0 1が徐 徐に常温 （海水温） にまで昇温する過程での冷熱を利用すること で捕うことができる。  Furthermore, a substantial part of the energy for cooling the electrolyzed hydrogen is-and the cold storage in the process of gradually raising the temperature of the hydrogen storage tank 0 1, which is cooled to liquid hydrogen and filled with hydrogen, to room temperature (seawater temperature). It can be caught by using it.

[0035]  [0035]
第 3図、 第 4図 （a) 、 ( b) 、第 5図 （a) 、 ( b) 、 ( c) において水素貯蔵タンク 0 1の内部に充填された水素吸蔵物質 であるタケ炭は、 第 5図 （b) に示す一辺が約 8 0 ミクロンの ハニカム状のタケ炭単位組織の集合体 （第 5図 （a) ) であり、 第 5図 （b) 、 ( c) においてその内部 0 3 (第一の水素格納部） に液体おょぴもしくは液状水素が貯蔵される。 タケ炭にある超 細孔 0 3 2は竹の細胞壁が炭化した約 2 ミクロンの厚さを持つ タケ炭の壁 0 3 2 Aを貫通する細孔でその大きさは約 4オング ス トローム径で 0 3に出入りする水素に対してフィルタおよび もしくはもしくは弁的役割をする。  Bamboo charcoal, a hydrogen storage material filled in the hydrogen storage tank 0 1 in FIGS. 3 and 4 (a), (b), 5 (a), (b) and (c), Fig. 5 (b) shows an aggregate of honeycomb-shaped bamboo charcoal unit structures (Fig. 5 (a)) with a side of approximately 80 microns. In Figs. 5 (b) and 5 (c), the inner 0 3 (first hydrogen storage part) stores liquid opium or liquid hydrogen. Bamboo charcoal wall 0 3 2 is a pore that penetrates bamboo charcoal wall 0 3 2 A, and its size is about 4 angstrom diameter. 0 Filters and / or acts as a valve against hydrogen entering and exiting 3.
又、 0 3 1はタケ炭の原料である竹の導水管に相当する約 1 0 0ミクロン径の通気路である。 この部分は充填時に一時的には 液体水素がたまっているが貯蔵時には気化水素がたまっている。 超細孔 0 3 2を通じて 0 3 と 0 3 1更には 0 3 4がつながって いる。 0 3 4は水素貯蔵タンク 0 1においてタケ炭が充填され ていない空間で主に気化水素が格納されている。 Reference numeral 0 3 1 is an air passage having a diameter of about 100 μm, which corresponds to a bamboo conduit for bamboo charcoal. This part is temporarily filled with liquid hydrogen at the time of filling, but vaporized during storage. 0 3 and 0 3 1 are connected through 0 3 2 and 0 3 4 are connected. 0 3 4 is a space in the hydrogen storage tank 0 1 that is not filled with bamboo charcoal, and mainly contains hydrogen vapor.
0 3 1 と 0 3 4とは第二の水素格納部を構成する。  0 3 1 and 0 3 4 constitute a second hydrogen storage unit.
[0036]  [0036]
第 4図 （a) は当該タンク 0 1に実施例 1で説明した海中に設置 された電気分解装箧で生成した気化水素を液化した （液化によ つて大幅に圧力が下がる） 水素を 1気圧で充填した直後 （未使 用で貯蔵開始時点） の当該タンク 0 1の状態、 第 4図 （b) は当 該タンク 0 1に水素 （液体水素及ぴもしくは液状水素） を充填 した後で徐徐に当該タンク 0 1の温度を上げて周囲温度 （常温 もしくは海水温） に達した後での貯蔵状態の当該タンク 0 1の 状態、 を表す。  Fig. 4 (a) shows that the vaporized hydrogen produced by the electrolysis apparatus installed in the sea explained in Example 1 was liquefied in the tank 0 1 (the pressure was greatly reduced by liquefaction). Fig. 4 (b) shows the state of the tank 0 1 immediately after filling with (when it is unused and at the start of storage). Fig. 4 (b) shows a gradual increase after filling the tank 0 1 with hydrogen (liquid hydrogen or liquid hydrogen). Shows the state of the tank 0 1 in the storage state after the temperature of the tank 0 1 is raised and the ambient temperature (room temperature or seawater temperature) is reached.
[0037] 第 4図 （a) において、 第一の水素格納部 0 3には第二の水素格 納部 0 3 1、 0 3 4より も多い全量の約 9 5 %の水素 （重量比） が充填されている。  [0037] In FIG. 4 (a), the first hydrogen storage section 0 3 includes approximately 95% hydrogen (weight ratio) of the total amount greater than the second hydrogen storage sections 0 3 1 and 0 3 4. Is filled.
第 4図 ) において、 液体水素は 0 3 と 0 3 1に 1気圧で充填 された直後の段階で 0 3 4の部分は液体水素が直ちに気化して 気液平衡状態となった。  In Fig. 4), liquid hydrogen was immediately vaporized into 0 3 and 0 3 1 at 1 atm, and the portion of 0 3 4 immediately vaporized and became a vapor-liquid equilibrium state.
その後、 当該タンク 0 1を徐徐に液体水素充填温度 （ 2 0 K ) から常温 （ 3 0 0 K ) まで昇温した。  Thereafter, the temperature of the tank 01 was gradually raised from the liquid hydrogen filling temperature (20 K) to room temperature (30 00 K).
充填直後には液体水素であった領域 0 3 1 も外部から当該タン クはそれらの液体水素は全て気化して図 4 ( b) に示すように、 0 3 4の部分と一体化 （同じ圧力） された気化水素の格納部と なった。 その後約 2 4時間で水素貯蔵タンク 0 1の温度は周囲 温度とほぼ平衡状態になり、 第二の水素格納部分における気化 水素の圧力は約 1 3気圧であった。  In the region 0 3 1 that was liquid hydrogen immediately after filling, the tank also vaporizes all of the liquid hydrogen from the outside and is integrated with the portion of 0 3 4 as shown in Fig. 4 (b). It became a containment of vaporized hydrogen. After about 24 hours, the temperature of the hydrogen storage tank 01 was almost in equilibrium with the ambient temperature, and the pressure of vaporized hydrogen in the second hydrogen storage part was about 13 atm.
[0038 ]  [0038]
前記したように第二の水素格納部 0 3 1 と 0 3 4における気化 水素の圧力は、 貯蔵開始時点の約 1気圧から圧力が平衡状態に なった 2 4時間後の約 1 3気圧まで徐徐に高めることで第一の 水素格納部 0 3からフィルタ状構造体 0 3 2を通じて、 気化し よう とする水素の圧力より も常に高い値に設定することにでき た。 この圧力 ： 1 3気圧は水素の臨界点 （温度 3 0 K ) の圧力 にほぼ相当する。 すなわち、 本実施形態では気化水素の圧力を 前記値に設定することで、 第一格納部 0 3にある水素を第二格 納部 （0 3 1 と 0 3 4 ) に実質的に排出させない圧力レベルに 設定できることが特徴である。 換言すると、 第一の水素格納部 0 3にある水素は周囲が常温およびもしくは海水温と等しい平 衡状態にあっても、 液体水素に近い密度を持つ液状状態で貯蔵 されていること、 を意味する。  As described above, the vaporized hydrogen pressure in the second hydrogen storage units 0 3 1 and 0 3 4 is gradually increased from about 1 atm at the start of storage to about 13 atm after 24 hours when the pressure reaches an equilibrium state. It was possible to set the pressure always higher than the pressure of the hydrogen to be vaporized through the filter-like structure 0 3 2 from the first hydrogen storage part 0 3. This pressure: 13 atm corresponds to the pressure at the critical point of hydrogen (temperature 30 K). That is, in this embodiment, by setting the pressure of vaporized hydrogen to the above value, the pressure at which hydrogen in the first storage unit 03 is not substantially discharged to the second storage unit (0 3 1 and 0 3 4). It can be set to level. In other words, the hydrogen in the first hydrogen storage unit 03 is stored in a liquid state having a density close to that of liquid hydrogen even if the surroundings are at an ordinary temperature and / or an equilibrium state equal to the seawater temperature. To do.
[0039] その結果、 第一の水素格納部 0 3から第二の水素格納部 （0 3 1 と 0 3 4 ) への水素の排出を防ぎ、 当該タンク 0 1内の気 化水素の圧力は 1 3気圧以内に保たれて当該タンク 0 1の機械 許容強度 2 0気圧以下が実現でき、 液体水素だけを充填したタ ンクの場合に問題となる未使用時にも気化した水素を排出 （ポ ィル ' オフ） することを防止できた。 [0039] As a result, the discharge of hydrogen from the first hydrogen storage unit 0 3 to the second hydrogen storage unit (0 3 1 and 0 3 4) is prevented, and the pressure of hydrogen vapor in the tank 0 1 is 13 atm. It is possible to achieve the allowable mechanical strength of the tank 0 1 below 20 atm, and discharge the vaporized hydrogen even when not in use, which is a problem in the case of a tank filled only with liquid hydrogen. I was able to prevent it.
充填時の平衡圧力を前記の 1気圧から充填途中で 0 . 5気圧に 下げることにより、 貯蔵時の平衡圧力を前記の 1 3気圧から約 半分に下げてもボイル · オフを抑制し得ることも確認した。  By lowering the equilibrium pressure at the time of filling from the above 1 atm to 0.5 atm in the middle of filling, it is possible to suppress boil-off even if the equilibrium pressure at the time of storage is lowered from the above 13 atm to about half. confirmed.
以上、水素吸蔵物質としてタケ炭を例に実施例を説明したが、 タケ炭以外でも例えば、 椰子殻炭、 ケナフ炭などの植物繊維を 原料とした炭、 グラフアイ ト、 活性炭のような炭化物、 ゼオラ イ トのような多孔質物質更には前記物質をペレツ ト、 粉末状に してそれらの表面の一部を例えばテフロンペース ト他のコーテ ング材料でコーテングした合成物質も使用出来る。 実施例 3  In the above, examples have been described by using bamboo charcoal as an example of the hydrogen storage material. However, other than bamboo charcoal, for example, charcoal such as coconut shell charcoal and kenaf charcoal, carbonite such as graphite and activated charcoal, A porous material such as zeolite, or a synthetic material in which the material is pelletized and powdered and a part of the surface thereof is coated with, for example, Teflon paste or other coating materials can be used.

As a means of transportation, a hydrogen storage tank that stores hydrogen, which is not liquid hydrogen itself, is characterized by transporting the ocean by transport ship 55.
