水素を消費できることになる。Transporting liquid hydrogen by a tanker has the characteristics of liquid hydrogen: very low temperature (-252.8 ° C.), low energy density (2 Mcal / liter), low specific gravity (0.0
708) has the following problems. (1) First, there is a problem of boil-off of liquid hydrogen. Since liquid hydrogen has a low boiling point, its evaporation rate is about 10 times the boil-off level of LNG tankers (0.025% / day, 0.15% in the improved type), and an extremely large amount of hydrogen gas is transported during transportation. Occur. In this regard, boil-off gas is used as fuel for navigation in LNG tankers. According to this method, about 2% of the loaded LNG can be used as fuel for voyages of 10,000 km class. Therefore, since the stored energy of liquid hydrogen is about 1/3 of LNG per volume, theoretically about 6% of the loaded amount of liquid hydrogen can be consumed.

The amount of boil-off gas for long-distance voyages is about 15-
It reaches 20%, and even if it is consumed as fuel for operation, it is an extremely large amount, so the rest must be discharged and discarded, and as a result, liquid hydrogen cannot be effectively used. In addition, there is a great danger that hydrogen gas will be released and discarded.

の浪費が強いられることになる。On the other hand, although the vacuum multi-layer insulation method is adopted in the LNG tanker as a boil-off suppressing method,
There is a problem that the volume of the tanker increases by 7 to 8%, and it is extremely difficult to adopt it for liquid hydrogen. Furthermore, it has been proposed that a balloon or accumulator tank be attached to the treatment of a large amount of boil-off gas, but the volume increase rate due to vaporization of liquid hydrogen is about
The volume of boil-off gas was 10 times that of a liquid hydrogen tank, which was 80 times that of a liquid hydrogen tank (in the case of a normal-pressure balloon) or 8 times that of a liquid hydrogen tank (in the case of a 10-atmospheric pressure accumulator tank). It is possible. (2) Secondly, there is a problem due to low energy density. In other words, liquid hydrogen has a capacity of four times or more in the same calorie as oil, and considering the installation of heat insulation walls, etc., a tanker with a capacity of 5 to 6 times that of a normal oil tanker is required, so mass transportation is extremely difficult. Have difficulty. (3) Third, since liquid hydrogen has a low specific gravity, the hull floats, resulting in instability of the hull, deterioration of steering performance, and inability to use a low-rotation energy-saving screw. Therefore, it is necessary to load a large amount of ballast water (about five times the weight of the cargo in the lower part of the spherical tank), which results in waste of navigation energy.

が現状である。Due to the above problems, it is extremely difficult to apply other energy transportation means such as an LNG tanker to mass transportation of liquid hydrogen, and at present, a small-sized inland purge ship uses liquid hydrogen. It only operates as a tanker. Also, for example, in the Euro-Quebec Project, which is planned as an open ocean liquid hydrogen tanker of tens of thousands of tons, we plan to install a large tank of ballast water while installing a spherical tank on the hull. At present, it is inevitable to increase the size and waste navigation energy.

There is no particular limitation as long as it complies with the conventional spherical tank for LNG and can withstand a slight pressure (about 1 to 3 atm) until the boil-off gas is sent out. The shape of the tank is not limited as long as it corresponds to the shape of the hull, and can be appropriately set to a spherical shape or a shape close to it. The upper part of the liquid hydrogen tank is provided with a degassing pipe serving as an outlet for boil-off gas. The liquid hydrogen tank is connected to the gaseous hydrogen tank through a connecting pipe connected to the gas vent pipe. Known degassing pipes and connecting pipes can be used.

ない。Examples of hydrogen storage alloys to be stored in the gaseous hydrogen tank include LaNi 5 H 6 series, TiFeH 2 series,
Conventionally known materials such as Mg 2 NiH 4 system and MgH 2 system can be used, but at a normal temperature and at a pressure that does not require a special pressure vessel (usually 10 atm or less)
Below, alloys capable of absorbing and releasing hydrogen are preferred. As an alloy satisfying such a condition, for example, LaNi 5 H
Mm known as 6 series and its homologous hydrogen storage alloys
Examples include alloys such as Ni 5 H 6 series and MmNi 4.5 Mn 0.5 H 2 (Mm: misch metal (shows a mixed rare earth metal cheaper than lanthanum)). In particular, the hydrogen absorption / desorption of the LaNi 5 H 6 type hydrogen storage alloy progresses quantitatively and rapidly among the hydrogen storage alloys. Therefore, as shown in FIG. 3, hydrogen can be easily handled by adjusting the temperature and pressure. You can
As the alloy, any of known storage methods for a hydrogen storage alloy such as a powder / shelf system and a copper microcapsule system can be adopted. The atmosphere inside the gaseous hydrogen tank needs to be adjusted to the equilibrium condition of the metal of the hydrogen storage alloy used to the metal hydride. For example, in the case of the LaNi 5 H 6 system, the temperature is usually 30 ° C. or less, and the vacuum is about 10 atm. Just do it. The internal temperature may drop significantly below the ambient temperature due to the influence of the liquid hydrogen tank, but the pressure in the gaseous hydrogen tank is simply reduced by that amount, and there is no particular hindrance in the transportation of liquid hydrogen.

の約１／１０容のＬａＮｉ5 を積載すれば十分であるこ
とになる。The loading amount of the hydrogen storage alloy is generally preferably determined in consideration of the amount of boil-off gas and the type of the hydrogen storage alloy to be loaded. For example, when the hydrogen storage alloy to be loaded is a lanthanum-nickel (LaNi 5 ) system, the loading amount can be obtained as follows. That is, if the average amount of boil-off gas in a standard 10,000 km voyage is about 17% of the liquid hydrogen at the time of departure, and the remaining amount consumed as nautical fuel is about 10%, LaNi 5 H 6 is hydrogen. Considering that the volume density is about 30% more than that of liquid hydrogen and that rapid hydrogen absorption advances only about 80% of the theoretical value, LaNi 5 necessary to absorb the above amount of gas of 10% is It is sufficient to load about 1/10 volume of the starting liquid hydrogen with LaNi 5 .

があることにも留意する必要がある。On the other hand, if the load capacity is large, it is possible to completely absorb the boil-off gas, but since the total weight of the hull increases with an increase in the load capacity, the above-mentioned load amount is also related to the total weight of the hull. Need to consider. That is, as shown in FIG. 2, it is preferable that the specific gravity of the total loading amount of liquid hydrogen and the hydrogen storage alloy (hereinafter referred to as “mixed loading amount”) be 1. In this case, since the specific gravity of the tanker itself is larger than 1, the total specific gravity of the hull is as shown by the broken line in FIG. That is, the mixed loading amount is preferably slightly smaller than the theoretical specific gravity value. Further, as is clear from FIG. 2, a hydrogen storage alloy having a higher specific gravity can make the specific gravity of the mixed loading amount 1 even with a small amount. Note that, for example, when the liquid hydrogen tank is a spherical tank, the outer space below the spherical tank where the gaseous hydrogen tank is installed is less than the equal volume of the spherical tank, so the upper limit of the hydrogen storage alloy loading capacity is It should also be noted that it will be less than about 50% of the combined load, and there is an upper limit on the load depending on its structure.

(1) Since a large amount of boil-off gas generated during navigation can be absorbed substantially by the hydrogen storage alloy,
It does not have to be released and discarded, and it can exhibit excellent safety, and at the same time, the hydrogen gas absorbed in the hydrogen storage alloy can be effectively used separately. (2) Furthermore, since the boil-off gas is easily absorbed by the hydrogen storage alloy, volume expansion due to its evaporation can be avoided. Therefore, it is not necessary to increase the size of the hull and install a new device. (3) Further, since the hydrogen storage alloy has a large specific gravity, the hydrogen storage alloy itself plays a role of ballast and can contribute to the improvement of stability, steerability, hull restoration and the like.
