More specifically, the present invention relates to a method and a system for transferring a medium storing electric energy obtained by a floating body (power generation floating body) such as a ship equipped with a wind turbine generator from the power generation floating body to an accumulation base of the storage medium.

Background Art

[0002] As one of the methods for obtaining renewable energy, offshore wind power generation has attracted attention. In the ocean, there are few restrictions on land and roads, and it is expected that the wind will blow stably in the same direction and with the same intensity.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Offshore wind power generation systems include two types: fixed-bottom systems (systems that fix the generator to the seabed) which are installed in shallow waters relatively close to land, and floating systems (systems that install the generator on a floating structure such as a ship) which can be deployed in deep waters. Of these types, floating systems have the advantage of being able to move the power generation float to areas with strong winds as needed, thereby efficiently recovering wind energy. However, regarding the delivery of energy generated from offshore power generation to the consumption site, unlike fixed-bottom systems, it is extremely difficult to lay power transmission cables from the system to land, and it may also be difficult to transmit power by microwave as described in Patent Document 1 (the transmission distance may be too long). Therefore, in the case of a floating system, the electrical energy generated by the power-generating floating body is either used to charge a battery, or the electrical energy is converted into the chemical energy contained in the hydrogen gas produced through a water splitting reaction induced by that energy, and this hydrogen gas is stored in a tank. The energy is then stored in a storage medium (battery, hydrogen tank) loaded onto the power-generating floating body, and the power-generating floating body is moved from the power generation site to a storage medium collection base on land or at sea as needed, and the storage medium is transferred from the power-generating floating body to the collection base. In this case, it is preferable that the transfer of the storage medium from the power-generating floating body to the collection base be carried out as quickly as possible so that the power-generating floating body can move to the power generation site quickly.

[0005] Thus, the main objective of the present invention is to enable the transfer of storage media from the power generation floating structure to the storage base in a floating offshore wind power generation system to be carried out as quickly as possible.

[0006] Incidentally, one known method of wind power generation mounted on offshore floating structures is the kite-type (kite-type power generation system), which generates electricity by raising and lowering a kite from the floating structure. When such kite power generation is carried out on an offshore floating structure, it is desirable that the floating structure can maintain its attitude as stably as possible even when a roll moment acts on it due to the wind force received by the kite. For this reason, a catamaran, that is, a hull with a structure in which the upper surfaces of two parallel hulls are connected by a deck section on which a kite-type power generation system is mounted, is advantageous as a structure for the floating structure. When such a catamaran is used as a floating structure, if the two hulls are detachable from the deck section, then when the floating structure is moved to a storage medium collection base to transfer the storage medium to the storage medium, the hull loaded with energy-stored medium can be detached from the deck section, and in its place, the hull loaded with energy-storable or empty storage medium can be attached, allowing the floating structure to move to the power generation site immediately, thereby extending the power generation time. This knowledge is utilized in the present invention. [Means for solving the problem]

[0007] According to the present invention, in one embodiment, the above problem is addressed in a floating offshore wind power generation system, in which energy generated by a power generation float is stored and the storage medium loaded on the power generation float is transferred to a collection base, wherein the power generation float has a catamaran structure in which two parallel hulls are connected on both sides of the deck, and the storage medium is loaded on the hulls, The first step is to move the power generation floating body to the collection base, The second process involves the power generation floating being anchored in a state where the deck portion of the power generation floating is straddling a long breakwater formed along the quay of the aforementioned storage base, with a waterway through which the body of the power generation floating can pass, and one side of the body of the power generation floating is entering the waterway. A third step of separating the hull on at least one side of the deck portion of the power-generating floating body from the deck portion, A fourth step is to advance the deck section on the long embankment section, A fifth step involves connecting another fuselage, which is loaded with an energy storage medium, to the side of the fuselage of the aforementioned deck section that has been detached, A sixth process in which the hull is connected to both sides of the deck section and the buoy departs from the power generation float. This is achieved by a method that includes [a specific method].

[0008] In the above configuration, the "storage medium" may be a battery on which electrical energy is charged, or it may be a tank storing hydrogen gas produced by a water splitting reaction using the electrical energy obtained from power generation, or liquid hydrogen obtained by liquefying it. The "power generation float" may be equipped with any type of wind power generation system, which may be a kite-type power generation system, and may be configured to store the energy obtained from power generation in the storage medium loaded on the hull. In the present invention, as described above, the power generation float has a catamaran structure, with two parallel hulls on both sides of the deck section that are detachably connected, and the storage medium is loaded on the hull. The "accumulation base" may be a facility installed offshore or on land to accumulate the storage medium for transport to energy consumption sites, and as described above, a long breakwater is formed along its quay, projecting above the water surface with a waterway through which the hull of the power generation float can pass.

[0009] In the method of the present invention described above, when transferring the storage medium for storing energy generated by a catamaran-shaped power generation float to a collection base, the power generation float moves to the collection base, and when it arrives, the deck of the power generation float straddles a long breakwater that protrudes from the water surface of the collection base, and one end of the hull of the power generation float enters the waterway between the long breakwater and the quay of the collection base, and the float is moored in this state. Then, the hull loaded with the storage medium is detached from the deck, and the deck is moved forward, and another hull loaded with an energy-storage medium is connected to the side of the deck that was detached from the hull, and the power generation float departs from the collection base. In other words, in the method of the present invention, at the collection base, the hull of the power generation float that is loaded with an energy-storage medium is replaced with another hull loaded with an energy-storage medium. With this configuration, when transferring storage media from the power generation float to the collection base, it is no longer necessary to keep the power generation float moored at the collection base while the storage media loaded on the fuselage is transferred to the collection base, and while energy-storable or empty storage media is transferred from the collection base to the fuselage. Once the fuselage exchange is complete, the power generation float can quickly depart from the collection base for the power generation site. Therefore, it is advantageous in that the power generation float can operate for a longer period of time and acquire more energy. In addition, in order to easily achieve the forward movement of the deck on the long breakwater, rails may be laid on the long breakwater that contact the underside of the deck and allow the deck to slide or move.

[0010] In the method of the present invention described above, a seventh step may be performed in which the storage medium loaded on the fuselage, which has been detached from the deck in the third step, is transferred to a collection base. During this transfer of the storage medium from the fuselage to the collection base, the power generation float is not used, and the float can be moved to the power generation site to carry out power generation.

[0011] In the method of the present invention described above, in the third step, only one side of the hull of the power generation float is detached from the deck section, and in the fourth step, the other side of the hull, which is still connected to the deck section, moves forward, causing the deck section to move forward on the breakwater. This eliminates the need to prepare another means to move the deck section forward on the breakwater. In this case, during a single port call of the power generation float to the storage base, only one side of the hull of the deck section may be replaced, or the hulls on both sides of the deck section may be replaced one by one in sequence.

[0012] Furthermore, in the method of the present invention described above, in the third step, the hulls on both sides of the power-generating float may be separated from the deck section, and in the fourth step, only the deck section may move forward along the long breakwater section. In that case, it will be possible to replace the hulls on both sides of the deck section at the same time, and it is expected that the time required to replace the two hulls will be shortened.

[0013] The above-described method of the present invention can be realized in a configuration in which the power generation floating body has a catamaran structure in which two parallel hulls capable of loading storage media are detachably connected on both sides of the deck portion, and the collection base is a long breakwater formed along its quay, with a waterway through which the hull of the power generation floating body can pass, projecting out of the water surface, and the deck portion of the power generation floating body can straddle and advance on the long breakwater above it. Thus, the above problem can be solved by another aspect of the present invention in a floating offshore wind power generation system, in which energy generated by the power generation floating body is stored and the storage media loaded on the power generation floating body is transferred to the collection base, The power-generating float has a catamaran structure in which two parallel hulls are detachably connected on both sides of the deck, and the storage medium is loaded onto the hulls. The aforementioned storage base is formed along its quay, with a long breakwater section projecting out of the water surface, separated by a waterway through which the body of the power-generating floating structure can pass, and on top of this, there is a long breakwater section that the deck section of the power-generating floating structure can straddle and advance. Furthermore, When the power generation floating structure is anchored with the deck section straddling the long dam section and one side of the floating structure's body entering the waterway, means for separating at least one side of the deck section's body from the deck section, Means for moving the deck section, from which at least one of the fuselage sections has been detached, forward on the long embankment section, Means for connecting another fuselage loaded with an energy storage medium to the side of the fuselage of the aforementioned deck section that has been detached, A system was established, This is achieved by a system configured to enable the power-generating float, to which the aforementioned hull is connected to the aforementioned deck section, to depart from the aforementioned collection base.

[0014] In the above system, the storage medium loaded on the fuselage detached from the deck section may be transferred to a collection base, and the fuselage may be replaced one by one at the long breakwater section, or the fuselage on both sides may be replaced simultaneously. [Effects of the Invention]

[0015] Thus, in the above configuration, the transfer of the storage medium from the floating offshore wind power generation system to the collection base can be carried out as quickly as possible, which is advantageous because it shortens the dwell time of the power generation floating at the receiving base, thereby increasing power generation time and power generation amount. As a result, the storage medium for energy generated and recovered offshore is transported with high efficiency, and an increase in the amount supplied to land is expected.

Best Mode for Carrying Out the Invention

[0019] The present invention will be described in detail below with reference to the accompanying drawings in several preferred embodiments. In the drawings, the same reference numerals indicate the same parts.

[0020] Configuration of a power generation floating structure In the offshore wind power generation system to which this embodiment is applied, a catamaran-type power generation float 10 is used, as schematically shown in Figures 1(A) and (B). The power generation float 10 has two hulls 12 and 13 arranged parallel to each other and connected to both sides of a deck section 14. A bridge or deckhouse 16 on which the power generation system 15 is installed is formed on the deck section 14. The power generation system 15 may be of any type, but typically it may be a kite-type power generation system that converts and recovers wind energy generated when raising a kite 15a that is flown in the air into electrical energy. The obtained electrical energy may be stored in a storage medium HT loaded on the hulls 12 and 13 in any manner. More specifically, in one embodiment, the obtained electrical energy may be converted into hydrogen energy (chemical energy possessed by hydrogen molecules) by generating hydrogen gas through a water splitting reaction, and the energy-holding hydrogen gas may be compressed or liquefied and stored in a tank as a storage medium HT, thereby storing the energy. In another embodiment, the generated electrical energy may be stored by charging a battery with a storage medium HT. The storage of energy from the power generation system to the storage medium HT may typically be performed automatically by operating machinery without human intervention.

[0021] Configuration of a storage media aggregation base In this embodiment, the storage medium HT loaded onto the bodies 12 and 13 that store the energy generated by the power generation floating body 10 in the offshore wind power generation system is transported to a collection base 20 installed offshore or on land as needed. The collection base 20 is basically composed of a base body 22 that protrudes from the water surface WL where the storage medium HT is collected, and a long breakwater section 23 that protrudes from the water surface WL. The long breakwater section 23 may be positioned using a waterway holder 25a to define a waterway 25 between it and the quay wall 22a of the base body 22, allowing the bodies 12 and 13 of the power generation floating body 10 to enter. Furthermore, in the long levee section 23, as will be described later, a body fixing device 24a for holding the body 12 or 13 in order to detach it from the deck section 14 when the body 12 or 13 of the power generation floating body 10 enters the waterway 25, a device (not shown) for releasing the connection between the deck section 14 and the body 12 or 13, a body fixing device 24b for holding another body 12a or 13a in order to connect another body 12a or 13a to the deck section 14 from which the body 12 or 13 has been detached, and a device (not shown) for connecting the deck section 14 and the body 12a or 13b may be provided. In addition, rails 24 for sliding or gliding the deck section 14 may be provided on the upper surface of the long levee section 23. On the other hand, the main base 22 may be equipped with machinery and equipment 26 for transferring the storage medium HT loaded on the fuselages 12 and 13 to the storage facility of the main base 22 when the fuselages 12 and 13 are moored in the waterway 25, such as a crane. The main base 22 and the long breakwater 23 may be either bottom-fixed or floating.

[0022] Replacement of the hull of the power generation floating platform In the offshore wind power generation system covered by this embodiment, it is assumed that the power generation floating body 10 moves to a location where it can generate power more effectively, generates power, stores energy in the storage medium HT, then moves to the collection base 20 at an appropriate time, unloads the energy-storage medium HT into the collection base 20, loads an energy-storage medium HT that is either ready to store energy or empty, and then moves again to a location where it can generate power to perform power generation and store energy in the storage medium HT, repeating this cycle. In this case, in order to recover more energy, as described in the summary of the invention, it is preferable to shorten the time that the power generation floating body 10 stays at the collection base 20 for the transfer of the storage medium HT loaded thereto to the collection base 20, and to maximize the amount of time that the power generation floating body 10 can generate power. Therefore, in this embodiment, taking advantage of the fact that the power generation floating body 10 has a catamaran structure, in order to shorten the time that the power generation floating body 10 stays at the collection base 20, when the power generation floating body 10 arrives at the collection base 20, the hulls 12 and 13 of the power generation floating body 10, which are loaded with the energy-storage medium HT, are detached from the deck section 14 and left in place, while other hulls 12a and 13a loaded with energy-storage medium HT that can store energy or are empty are connected, so that the power generation floating body 10 can move to a location where it can generate power again. In other words, in this embodiment, at the collection base 20, the hulls 12 and 13 of the power generation floating body 10 loaded with the energy-storage medium HT are replaced with other hulls 12a and 13a loaded with energy-storage medium HT that can store energy or are empty. With this configuration, the power generation floating body 10 can depart after arriving at the collection base 20 without requiring time to transfer the energy-storage medium HT from the fuselage 12 and 13 to the collection base 20, and without requiring time to transfer the energy-storage medium HT, whether available or empty, from the collection base 20 to the fuselage 12 and 13, thereby allowing for a longer power generation time.

[0023] (1) When replacing the torso one by one More specifically, in the case of a configuration in which one of the bodies of the power-generating floating body 10 is replaced, as shown in Figure 2(A), (i) the power-generating floating body 10 is moved to the storage base 20, (ii) one body 12 enters the waterway between the base body 22 and the long breakwater section 23, and the power-generating floating body 10 is moored with the deck section 14 straddling the long breakwater section 23. At this point, as shown in Figure 2(B), (iii) the body 12 is detached from the deck section 14, and (iv) the body 13 and the deck section 14 are moved forward. In addition, other bodies 12a and 13a loaded with energy-storing or empty storage medium HT are moved to the position where the deck section 14 can reach on the long breakwater section 23, and then (v) the deck section 14 and the body 12a are connected, and thus (vi) the power-generating floating body 10 departs from the storage base 20. On the other hand, in the fuselage 12 separated from the deck section 14, the storage medium loaded thereon is transferred to the base body 22 by the storage medium transfer machinery 26, and thereafter, energy-storage-capable or empty storage medium HT may be loaded onto the fuselage 12 and kept awaited for subsequent power-generating floating units arriving at the storage base.

[0024] Furthermore, when replacing the fuselage of the power-generating floating body 10, one fuselage on each side, in one embodiment, a storage base 20 may be constructed with long breakwater sections 23 on both sides of the base body 22, as shown in Figure 3. In this case, when the power-generating floating body 10 arrives at the storage base 20, (a) the deck section 14 is moored with one of the long breakwater sections 23 straddling it, (b) one fuselage section 12 is detached, and the deck section 14 and the other fuselage section 13 move forward, and (c) another fuselage section 12a is connected to the side of the deck section 14 from which the fuselage was detached. Subsequently, (d) the power generation floating body 10 is moored with its deck section 14 straddling the other long breakwater section 23, (e) the other body section 13 is detached, and the deck section 14 and the other body section 12a move forward, and (f) another body section 13a is connected to the side of the deck section 14 from which the body section was detached, and thus the power generation floating body 10, with both body sections replaced, departs from the storage base 20.

[0025] Furthermore, in another configuration in which the fuselage of the power-generating floating body 10 is replaced one fuselage on each side of the power-generating floating body 10, two sets of base bodies 22 and long breakwater sections 23 may be installed, as shown in Figure 4. In this case, when the power-generating floating body 10 arrives at one of the storage bases 20, (a) the deck section 14 is moored with the deck section 14 straddling one of the long breakwater sections 23, (b) one fuselage 12 is detached, and the deck section 14 and the other fuselage 13 move forward, and (c) another fuselage 12a is connected to the side of the deck section 14 from which the fuselage was detached. Thereafter, the power generation floating body 10 moves to the other collection base 20, (d) the power generation floating body 10 is moored with its deck section 14 straddling the long breakwater section 23 of the other collection base 20, (e) the other body 13 is detached, and the deck section 14 and the other body 12a move forward, (f) another body 13a is connected to the side of the deck section 14 where the body was detached, and thus the power generation floating body 10, with both sides of its body replaced, departs from the other collection base 20.

[0026] In both cases shown in Figures 3 and 4, the storage medium loaded on the fuselage 12 and 13, which have been separated from the deck section 14, is transferred to the base body 22 by the storage medium transfer machinery 26. After that, energy-storing or empty storage medium HT may be loaded onto the fuselage 12 and 13 and kept awaited for subsequent power-generating floats arriving at the storage base.

[0027] (2) When both fuselages are replaced at the same time In the case of a configuration in which the fusels 12 and 13 on both sides of the power-generating floating body 10 are replaced simultaneously, in one embodiment, as shown in Figure 5(A), a configuration in which the base body 22 is installed on both sides of a long breakwater 23 as the collection base 20 may be used. In this case, when the power-generating floating body 10 arrives at the collection base 20, (a) the deck section 14 is anchored with the deck section 14 straddling the long breakwater 23, (b) the fusels 12 and 13 on both sides are separated and the deck section 14 moves forward on its own, and (c) the fusels 12a and 13a are connected to both sides of the deck section 14 where the fuselage was separated, and the floating body departs from the collection base 20.

[0028] Furthermore, in another configuration in which the fusels 12 and 13 on both sides of the power-generating floating body 10 are replaced simultaneously, a configuration 23a in which the base body 22 and the long breakwater section 23 are integrated may be used, as shown in Figure 5(B). In this case, when the power-generating floating body 10 arrives at the storage base 20, (a) the deck section 14 will be moored with the deck section 14 straddling the long breakwater section 23a, (b) the fusels 12 and 13 on both sides will be separated and the deck section 14 will move forward on its own, and (c) the fusels 12a and 13a will be connected to both sides of the deck section 14 where the fuselage was separated, and the floating body will depart from the storage base 20.

[0029] Thus, according to the configuration of this embodiment described above, the power-generating float 10 can depart immediately after its body is replaced at the collection base 20, making it possible to have more power generation time and power generation amount. This embodiment is advantageous in that it allows for more power generation time and power generation amount, and is also advantageous when using a power-generating float equipped with a power generation system other than a kite-type power generation system, and such cases also fall within the scope of this embodiment.

[0030] While the above description is made in relation to embodiments of the present invention, many modifications and changes are readily possible for those skilled in the art, and it will be clear that the present invention is not limited to the embodiments illustrated above, but can be applied to various devices without departing from the concept of the present invention.
