Technical Field

[0001] This invention relates to a power generation system. Background Technology

[0002] Previously, a power generation system incorporating a wave generator was proposed, as in Patent Document 1.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2016-039130 Summary of the Invention

[0004] However, anchors and other components are required to prevent the generator from moving.

[0005] Therefore, the object of the present invention is to provide a power generation system incorporating a wave generator that can be easily constructed.

[0006] The power generation system of the present invention comprises: a power generation section including a wave generator; an energy storage section for storing electricity obtained from the power generation section; a generation section for generating at least one of hydrogen and an organic hydride based on the electricity obtained from the power generation section; and a container located below the wave generator for storing at least one of the hydrogen and the organic hydride obtained from the generation section.

[0007] The power generation system of the present invention comprises: a power generation section including a wave generator; an energy storage section for storing the electricity obtained by the power generation section; a generation section for generating at least one of hydrogen and an organic hydride based on the electricity obtained by the power generation section; and a container located below the generation section and in water for storing at least one of the hydrogen and the organic hydride obtained by the generation section.

[0008] A portion of the electricity generated by the power generation unit, such as the wave generator, is stored in the energy storage unit, while the remainder is used for the addition of hydrogen, etc., and is stored in the container as hydrogen or organic hydrides.

[0009] The container can be used as a counterweight in a power generation system.

[0010] A power generation system incorporating a wave generator can be easily constructed using a container located in water.

[0011] Preferably, the generating section is a hydrogen addition section for generating organic hydrides from aromatic compounds.

[0012] The container has: a first container for storing aromatic compounds; and a second container for storing organohydrogenates.

[0013] A portion of the electricity generated by the power generation unit, such as the wave generator, is stored in the energy storage unit, and the remainder is used for the addition of hydrogen, which is stored in a container (second container) as an organic hydride containing hydrogen.

[0014] Regarding the organic hydrides stored in the second container, compared to transporting hydrogen in a gaseous or liquid state, they can be easily transported using ships or the like, and the hydrogen can be easily extracted and used in locations far from power generation systems.

[0015] In addition, the aromatic compounds stored in the first container and the organic hydrides stored in the second container can be used as ballast for the power generation system.

[0016] A power generation system incorporating a wave generator can be easily constructed using a container located in water.

[0017] More preferably, the wave generator comprises: a float; a first moving part that moves up and down in conjunction with the up and down movement of the float; a second moving part that engages with the first moving part and rotates based on the up and down movement of the first moving part; and a power generation device that generates electricity based on the rotational force of the second moving part.

[0018] The power generation device can be placed in a location that is easy to waterproof, such as above the base.

[0019] More preferably, the power generation unit has a wind turbine.

[0020] The rotational force of the second moving part and the rotational force of the wind turbine rotor are transmitted to the power generation device via the power transmission part.

[0021] The power generation unit can be shared by wave generators and wind generators.

[0022] In addition, preferably, the power generation system also has a base portion located above the float of the power generator and holding the energy storage unit.

[0023] At least a portion of the wave generator passes through and is held in a state where it can swing in the vertical direction via a tubular or rod-shaped component that connects the base and the container.

[0024] The wave generator can be held in place by flexibly using the tubular components that connect the base and the container.

[0025] More preferably, the container has a donut shape.

[0026] Tubular or rod-shaped components extend from the outer wall of the inner side of the donut-shaped part.

[0027] Aromatic compounds pass through the interior of at least one of the tubular components.

[0028] Organic hydrides pass through the interior of at least one tubular component, which is different from the tubular component through which aromatic compounds pass.

[0029] The container is made of a donut shape, so it is difficult to be damaged by external pressure, and it is difficult to tip over even when the base is placed on top.

[0030] More preferably, the power generation system has a cover that covers the container in a state with gaps.

[0031] The cover is made up of transparent components.

[0032] Workers can enter the gaps to perform maintenance on the containers, or mobile monitoring devices can patrol between the containers and the cover to identify the damaged parts of the containers.

[0033] Additionally, preferably, the container has a first partition wall that is movable inside the container.

[0034] The first partition wall is used to separate the first container and the second container.

[0035] The size of the first container for storing aromatic compounds and the second container for storing organohydrides can be adjusted by using the first partition wall.

[0036] More preferably, the container has a third container for storing water or air.

[0037] The third container is used to adjust the weight of the container.

[0038] By adjusting the filling level of the third container with water, the sinking status of the counterweight container can be easily adjusted according to the filling level of the aromatic compounds in the first container and the organic hydrides in the second container.

[0039] In addition, filling the third container with air makes it easy for the container to float.

[0040] More preferably, the container has a second partition wall that is movable inside the container.

[0041] The second partition wall is used to separate the second and third containers.

[0042] The size of the second and third containers can be adjusted by using the second partition wall.

[0043] Additionally, preferably, the container has a third partition wall that is movable inside the container.

[0044] The third partition wall is used to separate the third container from the first container.

[0045] More preferably, the hydrogen addition section generates organic hydrides from aromatic compounds via an organic hydride electrolytic synthesis method.

[0046] Additionally, preferably, the power generation system also includes a propulsion device that is driven below the wave generator based on electricity from the energy storage unit.

[0047] The power generation department has wind turbines and solar generators.

[0048] The wind turbine and solar generator are mounted on top of the base.

[0049] The power generation system of the present invention comprises: a power generation section including a wave generator; an energy storage section for storing the electricity obtained by the power generation section; a generation section for generating at least one of hydrogen and an organic hydride based on the electricity obtained by the power generation section; and a container located below the generation section and in water for storing at least one of the hydrogen and the organic hydride obtained by the generation section.

[0059] Hereinafter, this embodiment will be described with reference to the accompanying drawings.

[0060] Furthermore, the implementation methods are not limited to the following embodiments. Additionally, the content described in one embodiment can, in principle, be applied to other embodiments as well. Furthermore, the various embodiments and their variations can be appropriately combined.

[0061] (Power Generation System 1)

[0062] The power generation system 1 of the first embodiment includes a power generation unit 10, a base unit 20, a control unit 30, an energy storage unit 40, a hydrogen storage unit 50, and a propulsion device 60 (see reference). Figures 1-5 ).

[0063] The power generation system 1 is configured such that the base 20 is located on the water, the wave generator 11 is located on the water surface, and the container 53 is located in the water.

[0064] (Power Generation Department 10)

[0065] The power generation unit 10 includes a wave generator 11, a solar generator 13, and a wind generator 15.

[0066] (Wave Generator 11)

[0067] The wave generator 11 has a float that oscillates in response to the up-and-down movement of the waves, and generates electricity based on the up-and-down movement of the float.

[0068] The wave generator 11 passes through the tubular component of the hydrogen storage section 50 and is held in the tubular component in a state that allows it to swing in the up and down direction.

[0069] However, the wave generator 11 can also pass through a rod-shaped component (e.g., a support) other than the tube connecting the base portion 20 and the container 53, and be held in the rod-shaped component in a state that allows it to swing in the up and down direction.

[0070] In the first embodiment, an example is shown where the wave generator 11 is held below the base portion 20 in a tubular component.

[0071] However, as shown in the second embodiment described later, a portion of the wave generator 11 (internal thread portion 11c, power generation device 11d, etc.) may also be disposed above the base portion 20.

[0072] (Solar generator 13)

[0073] The solar generator 13 generates electricity based on sunlight and other light.

[0074] The solar generator 13 is positioned above the base 20.

[0075] (Wind turbine 15)

[0076] The wind turbine 15 uses wind to rotate the rotor and generates electricity based on the rotational force of the rotor.

[0077] The wind turbine 15 is positioned above the base 20.

[0078] The AC power generated by the wave generator 11 and the AC power generated by the wind generator 15 are converted into DC power by the AC / DC converter and then supplied to the energy storage unit 40 or the generation unit 51.

[0079] (Base section 20)

[0080] The base 20 is located on the water and supports the solar generator 13, wind turbine 15, control unit 30, energy storage unit 40, generation unit 51, and first pump 58a to sixth pump 58f.

[0081] (Control Unit 30)

[0082] The control unit 30 controls each part of the power generation system 1.

[0083] For example, the drive control of the generation unit 51 and the like is performed based on the charging state of the energy storage unit 40.

[0084] Specifically, when the charging state of the energy storage unit 40 is insufficient, the control unit 30 controls each part of the power generation system 1 in such a way that the power obtained from the power generation unit 10 is stored in the energy storage unit 40 without driving the generation unit 51.

[0085] When the energy storage unit 40 is fully charged, i.e., in a fully charged state, the generation unit 51 and the like are driven by the power obtained from the power generation unit 10 without charging the energy storage unit 40.

[0086] (Energy Storage Unit 40)

[0087] The power storage unit 40 stores the electricity obtained from the power generation unit 10 and supplies the electricity to the electrical equipment of the power generation system 1, such as the generation unit 51.

[0088] (Hydrogen Storage Department 50)

[0089] The hydrogen storage unit 50 includes a generation unit 51, a container 53, a partition wall, tubular components, and a pump.

[0090] The hydrogen storage unit 50 has a first container 53a, a second container 53b, and a third container 53c.

[0091] The hydrogen storage section 50 has a first partition wall 55a, a second partition wall 55b, and a third partition wall 55c.

[0092] The tubular components of the hydrogen storage section 50 include a first tube 57a, a second tube 57b, a third tube 57c, a fourth tube 57d, a fifth tube 57e, and a sixth tube 57f.

[0093] The pumps of the hydrogen storage unit 50 include a first pump 58a, a second pump 58b, a third pump 58c, a fourth pump 58d, a fifth pump 58e, and a sixth pump 58f.

[0094] (Generation Department 51)

[0095] The generation section 51 is a first hydrogen addition device for generating organic hydrides such as methylcyclohexane from aromatic compounds such as toluene through an organic hydride electrolytic synthesis method.

[0096] However, the generation unit 51 may also be configured to include: a hydrogen generation device that performs water electrolysis to generate hydrogen; and a second hydrogen addition device that adds the generated hydrogen to an aromatic compound to generate an organic hydride.

[0097] (Container 53)

[0098] Container 53 is a rotating body that can be configured with a rotation axis on the outside of a circle, that is, it has an approximate donut shape.

[0099] Container 53 is used for storing organic hydrides and the like inside.

[0100] In addition, container 53 is also used as a counterweight for power generation system 1.

[0101] The container 53 is located in the water and is connected to the base 20 above the water by means of tubular and rod-shaped components.

[0102] Inside container 53, three spaces (first container 53a, second container 53b, and third container 53c) are formed by a first partition wall 55a, a second partition wall 55b, and a third partition wall 55c.

[0103] The first container 53a is a space formed between the first spacer 55a and the third spacer 55c, used for storing aromatic compounds.

[0104] The first container 53a is connected to the first pipe 57a and the second pipe 57b.

[0105] The second container 53b is a space formed between the first partition wall 55a and the second partition wall 55b, used for storing organic hydrides.

[0106] The second container 53b is connected to the third tube 57c and the fourth tube 57d.

[0107] The third container 53c is a space formed between the second partition wall 55b and the third partition wall 55c, used for storing water or air.

[0108] The third container 53c is connected to the fifth tube 57e and the sixth tube 57f.

[0109] (Spacing)

[0110] The first partition wall 55a is movable inside the container 53 to separate the first container 53a and the second container 53b.

[0111] A sealing component (first sealing component 55a1) such as an O-ring is provided between the first partition wall 55a and the inner wall of the container 53 to ensure a tight seal.

[0112] The first partition wall 55a can move due to the pressure difference between the first container 53a and the second container 53b, or it can move electrically by means of an actuator.

[0113] The second partition wall 55b is movable inside the container 53 to separate the second container 53b and the third container 53c.

[0114] A sealing component (second sealing component 55b1) such as an O-ring is provided between the second partition wall 55b and the inner wall of the container 53 to ensure a tight seal.

[0115] The second partition wall 55b can move due to the pressure difference between the second container 53b and the third container 53c, or it can move electrically by means of an actuator.

[0116] The third partition wall 55c is fixed inside the container 53 and is used to separate the third container 53c and the first container 53a.

[0117] The third partition wall 55c can also be configured to move inside the container 53.

[0118] In this case, one of the first spacer wall 55a and the second spacer wall 55b can be fixed inside the container 53.

[0119] The first partition wall 55a moves inside the container 53, causing the size of the first container 53a and the second container 53b to change.

[0120] The second partition wall 55b moves inside the container 53, causing the sizes of the second container 53b and the third container 53c to change.

[0121] (Tubular component)

[0122] The lower end of the first tube 57a is connected to the inlet of the first container 53a, and the upper end is connected to an external first device (not shown) that supplies aromatic compounds to the first container 53a.

[0123] The lower end of the second tube 57b is connected to the outlet of the first container 53a, and the upper end is connected to the inlet of the generating section 51.

[0124] The lower end of the third tube 57c is connected to the inlet of the second container 53b, and the upper end is connected to the outlet of the generating section 51.

[0125] The lower end of the fourth tube 57d is connected to the outlet of the second container 53b, and the upper end is connected to a second external device (not shown) that receives organic hydrides from the second container 53b.

[0126] The lower end of the fifth tube 57e is connected to the inlet of the third container 53c, and the upper end is open.

[0127] The lower end of the sixth tube 57f is connected to the outlet of the third container 53c, and the upper end is open.

[0128] External first and second devices are facilities installed on ships or land, etc.

[0129] (pump)

[0130] The first pump 58a is used to supply aromatic compounds from the first device to the first container 53a.

[0131] The second pump 58b is used to supply aromatic compounds from the first container 53a to the generating section 51.

[0132] The third pump 58c is used to supply organic hydrides from the generation section 51 to the second container 53b.

[0133] The fourth pump 58d is used to supply organic hydrides from the second container 53b to the second device described above.

[0134] The fifth pump 58e is used to supply water or air from the outside to the third container 53c.

[0135] The sixth pump 58f is used to discharge water or air from the third container 53c to the outside.

[0136] (Propulsion device 60)

[0137] The propulsion device 60, consisting of a propeller or the like, is located below the container 53, further below the wave generator 11, and in the water (sea).

[0138] The propulsion device 60 is driven by electricity supplied from the energy storage unit 40 and is used for the movement of the power generation system 1 and the maintenance of a predetermined position.

[0139] (action)

[0140] Next, the operation of the pump in power generation system 1 will be explained.

[0141] Upon startup, the control unit 30 activates the first pump 58a to supply aromatic compounds from an external first device to the first container 53a. Therefore, the first container 53a is in a larger state (see reference). Figure 4 ).

[0142] Since no organic hydrides have yet been generated, the second container 53b is in a smaller state.

[0143] In addition, the control unit 30 causes the fifth pump 58e to operate, supplying water from the outside to the third container 53c.

[0144] The weight of the aromatic compounds in the first container 53a and the water in the third container 53c causes container 53 to sink into the water.

[0145] Electricity is generated by the power generation of the wave generator 11, solar generator 13, and wind generator 15 in the power generation unit 10 and stored in the energy storage unit 40.

[0146] If the energy storage unit 40 becomes fully charged, the control unit 30 stops supplying power from the power generation unit 10 to the energy storage unit 40 and starts supplying power from the power generation unit 10 to the generation unit 51.

[0147] The term "fully charged" here does not necessarily mean 100% charge; it can also mean around 80-90% of the specified charge level.

[0148] In addition, the control unit 30 causes the second pump 58b to operate to supply aromatic compounds from the first container 53a to the generating unit 51.

[0149] The generation section 51 utilizes aromatic compounds to generate organic hydrides.

[0150] The control unit 30 causes the third pump 58c to operate, supplying the organic hydride generated by the generating unit 51 to the second container 53b.

[0151] The aromatic compounds in the first container 53a decrease, while the organic hydrides in the second container 53b increase. Consequently, the first partition wall 55a moves, causing the first container 53a to decrease in size and the second container 53b to increase in size (see reference). Figure 5 ).

[0152] In order to maintain a constant waterline, the control unit 30 adjusts the water volume in the third container 53c to adjust the sinking status of the container 53.

[0153] When the container 53 is shallow, the control unit 30 activates the fifth pump 58e to supply water to the third container 53c from the outside.

[0154] In this case, the second partition wall 55b moves to increase the size of the third container 53c.

[0155] If container 53 sinks to a greater depth, control unit 30 activates the sixth pump 58f to discharge water from the third container 53c to the outside.

[0156] In this case, the second partition wall 55b moves to reduce the size of the third container 53c (see reference). Figure 4 ).

[0157] When performing maintenance on container 53 or when container 53 is floating on water, control unit 30 activates sixth pump 58f to discharge water from third container 53c to the outside, and activates fifth pump 58e to supply air to third container 53c from the outside.

[0158] In this case, the buoyancy of container 53 causes container 53 to float to near the water surface.

[0159] (The effect of storing electricity and organic hydrogen compounds)

[0160] In the first embodiment, a portion of the electricity obtained by the power generation unit 10, such as the wave generator 11, is stored in the power storage unit 40, and the remainder is used to add hydrogen and is stored in the container 53 (second container 53b) as a hydrogen-containing organic hydride.

[0161] The electricity stored in the energy storage unit 40 is used to drive the electrical equipment of the power generation system 1, as well as the external electrical equipment.

[0162] Alternatively, the power storage unit 40, which is in a state of storing electricity, can be removed and used to drive external electrical equipment.

[0163] Regarding the organic hydride stored in the second container 53b, compared to transporting hydrogen in a gaseous or liquid state, it can be easily transported using ships or the like, and the hydrogen can be easily extracted and used in a location far from the power generation system 1.

[0164] In addition, the aromatic compounds stored in the first container 53a and the organic hydrides stored in the second container 53b can be used as counterweights for the power generation system 1.

[0165] A power generation system 1 containing a wave generator 11 can be easily constructed by using a container 53 located in water.

[0166] (The effect of maintaining the wave generator by using the tube of hydrogen storage section 50)

[0167] In addition, at least a portion (float, etc.) of the wave generator 11 passes through and remains in the tube of the hydrogen storage section 50, such as the first tube 57a, in a state that allows it to swing in the up-down direction.

[0168] Therefore, the wave generator 11 can be held in place by flexibly using tubular components that connect the base 20 and the container 53.

[0169] (The effect of setting the container to a donut shape)

[0170] Because the container 53 is made in a donut shape, it is difficult to be damaged by external pressure, and it is difficult to tip over even if the base part 20 is placed on top.

[0171] (The effect of setting the first partition)

[0172] The size of the first container 53a for storing aromatic compounds and the second container 53b for storing organic hydrides can be adjusted according to the degree of filling by using the first partition wall 55a.

[0173] (The effect of setting the third container 53c)

[0174] By adjusting the filling level of water into the third container 53c, the sinking status of the counterweight container 53 can be easily adjusted according to the filling levels of aromatic compounds in the first container 53a and organic hydrides in the second container 53b.

[0175] In addition, container 53 can be easily made to float by filling the third container 53c with air.

[0176] (The effect of setting a second partition)

[0177] Furthermore, the size of the second container 53b and the third container 53c for storing water or air can be adjusted by using the second partition wall 55b.

[0178] (Methods of hydrogen storage)

[0179] Furthermore, in the first embodiment, an example was described in which a portion of the electricity obtained from the power generation unit 10 was stored in container 53 as an organic hydride containing hydrogen.

[0180] However, the substances stored in container 53 are not limited to organic hydrides, as long as container 53 is configured to be positioned further below at least one of the wave generator 11 and the generating unit 51, and can be flexibly used as counterweight in water. For example, it is conceivable to store hydrogen obtained by electrolysis of water in container 53 in a gaseous or liquid state.

[0181] In this case, the generation unit 51 functions as a hydrogen generation device that generates hydrogen by electrolyzing water.

[0182] (The effect of storing electricity and hydrogen)

[0183] In the first embodiment, a portion of the electricity obtained by the power generation unit 10, such as the wave generator 11, is stored in the energy storage unit 40, and the remainder is used to generate hydrogen, which is stored in the container 53.

[0184] The electricity stored in the energy storage unit 40 is used to drive the electrical equipment of the power generation system 1, as well as the external electrical equipment.

[0185] Alternatively, the power storage unit 40, which is in a state of storing electricity, can be removed and used to drive external electrical equipment.

[0186] In addition, container 53 can be used as a counterweight for power generation system 1.

[0187] A power generation system 1 containing a wave generator 11 can be easily constructed by using a container 53 located in water.

[0188] (A specific example of the wave generator 11)

[0189] In addition, in the first embodiment, an example was described in which the float of the wave generator 11 and the power generation device are housed in a housing and located at a position lower than the base portion 20.

[0190] Specifically, one approach is to change the volume of the air chamber by moving the float up and down, and then use this volume change to rotate the turbine and generate electricity.

[0191] Alternatively, one could conceive of the following method: the up-and-down movement of a float causes the pinion of a power generation device, which engages with a rack in a tubular component, to rotate, and power is generated based on this rotation.

[0192] Alternatively, the following method can be conceived: the propeller moves up and down by the up and down movement of the float, and is located on the water above or below the float, rotating around an axis parallel to the vertical direction of the tubular component, thereby generating electricity based on this rotation.

[0193] Furthermore, the propeller is not limited to rotating about an axis parallel to the vertical direction; it can also rotate about an axis parallel to the horizontal direction. In this case, the propeller rotates in accordance with the lateral tidal flow. Additionally, similar to the propulsion device 60, the propeller can also be located below the container 53.

[0194] However, the wave generator 11 is not limited to the above-described manner, and may also have other structures (second embodiment, see reference). Figures 6-8 ).

[0195] The wave generator 11 of the second embodiment has a float 11a, an external threaded portion (first moving part) 11b, an internal threaded portion (second moving part) 11c, and a power generation device 11d.

[0196] The external thread portion 11b is provided on the outer wall of the tubular component (e.g., the first tube 57a) and covers the side of the tubular component.

[0197] The external threaded part 11b is fixed to the upper part of the float 11a and moves up and down in response to the up and down movement of the float 11a.

[0198] The internal thread portion 11c engages with the external thread portion 11b when its vertical movement is suppressed.

[0199] Therefore, the external thread portion 11b moves in the vertical direction, thereby causing the internal thread portion 11c to rotate without moving in the vertical direction.

[0200] The internal thread portion 11c and the power generation device 11d are, for example, disposed on the base portion 20.

[0201] A portion of the external threaded portion 11b and the float 11a are disposed below the base portion 20.

[0202] The internal thread portion 11c and the external thread portion 11b rotate in response to each other's up-and-down movements, and the power generation device 11d generates electricity based on the rotational force of the internal thread portion 11c.

[0203] In this case, the power generation device 11d can be positioned above the base portion 20, or in a location where waterproofing measures can be easily implemented.

[0204] Alternatively, the internal threaded portion 11c and the power generation device 11d can be included in the housing containing the float 11a, and move up and down together with the float 11a. In this case, the external threaded portion 11b is fixed to the tubular component and is not linked to the up and down movement of the float 11a.

[0205] (Container 53 with cover 59)

[0206] In addition, such as Figure 6 As shown, a cover 59 can be set in container 53 to cover the entire container 53.

[0207] By setting up the cover 59, the container 53 can be prevented from being corroded by seawater, etc.

[0208] For example, cover 59 is made of pressure-resistant reinforced transparent hard glass.

[0209] In this case, the damage to container 53 can be easily visually confirmed from the outside of cover 59.

[0210] In addition, it is preferable to provide a gap between the inner wall of the cover 59 and the outer wall of the container 53.

[0211] Workers can enter the gap to perform maintenance work on container 53, or mobile monitoring devices can patrol between container 53 and cover 59 to determine the damaged parts of container 53.

[0212] (Shared power generation equipment)

[0213] In addition, examples of wave generator 11 and wind generator 15 respectively were described in the first embodiment.

[0214] However, the power generation device 11d that generates electricity based on the rotational force of the internal thread portion 11c of the wave generator 11 can also generate electricity based on the rotational force of the impeller 15a of the wind turbine generator 15.

[0215] In this case, a power transmission section 11e is provided between the rotating parts of the wave generator 11, such as the internal thread section 11c, and the rotating parts of the wind turbine 15, such as the impeller 15a.

[0216] The rotational force of the internal thread portion 11c and the rotational force of the impeller 15a are transmitted to the power generation device 11d via the power transmission portion 11e, and the power generation device 11d generates electricity based on the aforementioned rotational force.

[0217] Therefore, the wave generator 11 and the wind generator 15 can share the same power generation unit.

[0218] Several embodiments of the present invention have been described, but these embodiments are merely illustrative and are not intended to limit the scope of the invention. These embodiments can be implemented in various other ways, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
