Description

Technical Field

[0001] This application relates to the field of wind power hydrogen production technology, and more specifically, to an offshore hydrogen production platform. Background Technology

[0002] An offshore wind-powered hydrogen production platform is a comprehensive offshore energy system that deeply integrates offshore wind power generation with water electrolysis for hydrogen production. This platform utilizes the electricity generated by offshore wind turbines to produce hydrogen through water electrolysis, achieving on-site utilization and energy carrier conversion of offshore wind power. In existing offshore wind-powered hydrogen production systems, the electricity output from wind power generation is random, intermittent, and subject to wide fluctuations. Although hydrogen production is considered an effective way to utilize wind power, the water electrolysis hydrogen production equipment itself has high requirements for the stability of the input power. Drastic fluctuations in wind power directly lead to decreased hydrogen production efficiency, increased energy consumption, and shortened equipment lifespan.

[0003] Therefore, how to improve hydrogen production efficiency and ensure the stability of hydrogen production systems has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the purpose of this application is to provide an offshore hydrogen production platform to improve hydrogen production efficiency and ensure the stability of the hydrogen production system.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A marine hydrogen production platform includes a platform body, a wind power generation module, a photovoltaic power generation module, a wave power generation module, and a hydrogen production and storage module, wherein the wind power generation module, the photovoltaic power generation module, and the wave power generation module are all electrically connected to the hydrogen production and storage module.

[0007] The platform body includes at least two decks, the top deck is the top deck, the bottom deck is the bottom deck, and there is at least one bottom deck. The bottom deck is the support deck. The photovoltaic power generation module and the wind power generation module are both installed on the top deck, and each bottom deck is equipped with the hydrogen production and storage module.

[0008] The platform body includes a float, which is connected to the support deck, and the wave energy generation module is disposed between the float and the support deck.

[0009] Optionally, in the above-mentioned offshore hydrogen production platform, a first support assembly and a second support assembly are provided between any two adjacent decks. The first support assembly includes a plurality of spaced support columns, each of which is arranged around the bottom deck. The hydrogen production and storage module constitutes the second support assembly.

[0010] Optionally, in the aforementioned offshore hydrogen production platform, the hydrogen production and storage module includes a shell and a hydrogen production and storage module assembly, the hydrogen production and storage module assembly being disposed inside the shell, and the shell being provided with multiple vent holes.

[0011] Optionally, in the aforementioned offshore hydrogen production platform, between any two adjacent decks, the hydrogen production and storage modules comprise multiple modules arranged in an array.

[0012] Optionally, in the above-mentioned offshore hydrogen production platform, the platform body includes a third support component, which is disposed between the float and the support deck, and the third support component includes a plurality of spaced columns.

[0013] Optionally, in the aforementioned offshore hydrogen production platform, for each of the columns, the radial dimension of the column gradually increases along the axial direction of the column, from the direction closer to the support deck to the direction farther away from the support deck.

[0014] Optionally, in the aforementioned offshore hydrogen production platform, the third support component includes a central column and multiple side columns located around the central column, and the float and each of the side columns are provided with ballast compartments.

[0015] Optionally, in the above-mentioned offshore hydrogen production platform, a fourth support assembly is provided between the floating body and the support deck. The fourth support assembly includes at least one support rod, and the wave energy power generation module is disposed on the support rod, which constitutes a wave energy power generation module mounting rod.

[0016] Optionally, in the above-mentioned offshore hydrogen production platform, at least one of the bottom decks is provided with a hydrogen transmission interface, and each of the hydrogen production and storage modules is connected to the hydrogen transmission interface through a pipeline.

[0017] Optionally, in the aforementioned offshore hydrogen production platform, the wind power generation module includes a tower and a wind turbine. The tower extends through the top deck and each of the bottom decks and is connected to the support deck. The wind turbine is located at the top of the tower.

[0018] As can be seen from the above scheme, the offshore hydrogen production platform disclosed in this application has wind power generation module, photovoltaic power generation module, and wave power generation module all electrically connected to the hydrogen production and storage module, realizing on-site consumption of electrical energy and avoiding long-distance power transmission losses. The three are integrated into the main body of the platform, working together and complementing each other to supply power to the hydrogen production and storage module. When the power generation of any one of the wind power generation module, photovoltaic power generation module, and wave power generation module is unstable, the other two can be used to supply power to the hydrogen production and storage module. This can smooth out the intermittency and fluctuation of single energy generation, reduce the number of start-ups and shutdowns of the hydrogen production and storage module, improve the continuity and stability of power supply, thereby improving hydrogen production efficiency, improving the stability of the hydrogen production system, and achieving the goals of multi-energy complementarity, on-site hydrogen production, stability and safety, and easy operation and maintenance.

The wind power generation modules, photovoltaic power generation modules, and wave power generation modules are arranged in layers, avoiding the concentration of all modules on the same deck. This fully utilizes the space of each layer of the platform, improving space utilization. The layered arrangement according to the energy requirements of each module reduces pipeline length and saves investment. The multi-deck design improves hydrogen production and storage capacity and reduces unit output costs. Attached Figure Description

[0031] The core of this application is to disclose an offshore hydrogen production platform to improve hydrogen production efficiency and ensure the stability of the hydrogen production system.

[0032] Offshore wind power hydrogen production utilizes offshore wind power to generate electricity, which is then used to produce hydrogen through water electrolysis, making it safe and hygienic. The produced hydrogen is compressed or liquefied and stored, and can be transported via pipelines, ships, etc., ultimately finding applications in transportation, chemical industry, industrial heat processing, and power peak shaving, among other fields. However, the electrical energy output from wind power generation is random, intermittent, and subject to wide fluctuations. Drastic fluctuations in wind power output directly lead to a decrease in hydrogen production efficiency. This application addresses this issue and represents an improvement based on these characteristics.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0034] like Figures 1-6As shown in the figure, this application discloses an offshore hydrogen production platform, including a platform body 100, a wind power generation module 200, a photovoltaic power generation module 300, a wave power generation module 400, and a hydrogen production and storage module 500. The platform body 100 serves as the installation platform for each module. The wind power generation module 200, the photovoltaic power generation module 300, and the wave power generation module 400 are all electrically connected to the hydrogen production and storage module 500 to supply power to the hydrogen production and storage module 500, enabling the hydrogen production and storage module 500 to produce hydrogen through water electrolysis. The platform body 100 includes at least two decks 110. The top deck is called the top deck 111, and the bottom deck is called the bottom deck 112. There is at least one bottom deck 112. The bottommost bottom deck 112 is a support deck 113. Photovoltaic power generation modules 300 and wind power generation modules 200 are both installed on the top deck 111. There is at least one photovoltaic power generation module 300. Each bottom deck 112 is equipped with a hydrogen production and storage module 500. There is at least one hydrogen production and storage module 500 on each bottom deck 112. The platform body 100 includes a float 120, which is connected to the support deck 113. A wave energy generation module 400 is installed between the float 120 and the support deck 113.

[0035] The float 120 provides displacement for the platform body 100, ensuring the stability of the platform body 100. The float 120 is preferably made of concrete, which has a larger ballast weight than conventional seawater, which can significantly lower the center of gravity of the overall system and improve stability.

[0036] In practical use, the wind power generation module 200, photovoltaic power generation module 300, and wave power generation module 400 are all electrically connected to the hydrogen production and storage module 500 to supply power to the hydrogen production and storage module 500. The three work together to achieve a continuous and stable power supply to the hydrogen production and storage module 500. The hydrogen production and storage module 500 produces hydrogen by electrolyzing water, stores the produced hydrogen, and finally connects to the hydrogen transport ship through the hydrogen transmission interface 114 set on the platform body 100 to realize the production, storage, and external delivery of hydrogen.

[0037] The offshore hydrogen production platform disclosed in this application has a wind power generation module 200, a photovoltaic power generation module 300, and a wave power generation module 400 all electrically connected to a hydrogen production and storage module 500, enabling local consumption of electrical energy and avoiding long-distance power transmission losses. The three modules are integrated into the platform body 100, working synergistically and complementing each other to supply power to the hydrogen production and storage module 500. When the power generation of any one of the wind power generation module 200, photovoltaic power generation module 300, and wave power generation module 400 is unstable, the other two can be used to supply power to the hydrogen production and storage module 500. This can smooth out the intermittency and fluctuation of single-energy power generation, reduce the number of start-ups and shutdowns of the hydrogen production and storage module 500, and improve the continuity and stability of power supply. In this way, hydrogen production efficiency can be improved, the stability of the hydrogen production system can be improved, and the goals of multi-energy complementarity, local hydrogen production, stability and safety, and easy operation and maintenance can be achieved. The platform body 100 includes at least two decks 110, which can provide installation platforms for various modules. The multi-deck design of the platform body 100 can significantly increase the air gap of the platform body 100, prevent the photovoltaic power generation module 300 from being affected by waves and thus reduce power generation efficiency, and prevent water from entering the hydrogen production and storage module 500 and related electrical facilities, thus avoiding equipment damage. The wind power generation module 200, photovoltaic power generation module 300 and wave power generation module 400 are arranged in layers, avoiding the concentration of various modules on the same deck 110, which can make full use of the space of each layer of the platform body 100 and improve space utilization. The layered arrangement according to the energy required by each module can reduce pipeline length and save investment. The multi-deck design of the platform body 110 can improve hydrogen production and storage capacity and reduce unit output cost.

[0038] In some specific embodiments of this application, the offshore hydrogen production platform includes a rectifier and energy storage module. Wind power generation module 200, photovoltaic power generation module 300 and wave energy generation module 400 are all electrically connected to the rectifier and energy storage module. The rectifier and energy storage module is electrically connected to the hydrogen production and storage module 500. The rectifier and energy storage module is used to rectify and store the power generated by wind power generation module 200, photovoltaic power generation module 300 and wave energy generation module 400, and to supply power to the hydrogen production and storage module 500.

[0039] In some specific embodiments of this application, such as Figures 1-5 As shown, a first support assembly 130 and a second support assembly are provided between any two adjacent decks 110. The first support assembly 130 includes a plurality of spaced support columns 131, which are arranged around the bottom deck 112. The hydrogen production and storage module 500 constitutes the second support assembly. The arrangement of the support columns 131 around the bottom deck 112 avoids interference with the hydrogen production and storage module 500 and facilitates its installation.

[0040] Specifically, the platform body 100 shown in the figure includes three decks: a top deck 111, a bottom deck 112 in the middle layer, and a support deck 113 at the bottom. As shown in the figure, a first support assembly 130 and a second support assembly are arranged between the top deck 111 and the bottom deck 112 in the middle layer. The first support assembly 130 includes four support columns 131 arranged around the bottom deck 112 in the middle layer. The hydrogen production and storage module 500 located between the two serves as the second support assembly. Furthermore, the top of each support column 131 is connected to the top deck 111, the bottom of each support column 131 is connected to the bottom deck 112 in the middle layer, and the top of each hydrogen production and storage module 500 abuts against the top deck 111.

[0041] A first support assembly 130 and a second support assembly are also provided between the bottom deck 112 and the support deck 113 of the intermediate layer. Their specific structures are the same as those of the first support assembly 130 and the second support assembly of the top deck 111 and the bottom deck 112 of the intermediate layer, and will not be described again here. Each support column 131 can penetrate the bottom deck 112 of the intermediate layer and connect to the support deck 113 at its bottom. In this configuration, the weight of the bottom deck 112 of the intermediate layer is borne by the hydrogen production and storage module 500. Alternatively, each support column 131 can penetrate the bottom deck 112 of the intermediate layer and connect to it, with its bottom connected to the support deck 113. In this configuration, each support column 131 can simultaneously provide support for both the top deck 111 and the bottom deck 112 of the intermediate layer. Each support column 131 works in conjunction with the hydrogen production and storage module 500 to provide support. Alternatively, support columns 131 can be installed between the top deck 111 and the bottom deck 112 of the intermediate layer, and between the bottom deck 112 of the intermediate layer and the support deck 113. The number of support columns 131 between each deck 110 may be the same or different. In this scheme, each support column 131 and the hydrogen production and storage module 500 work together to provide support for each deck 110.

[0042] It should be noted that the number of support columns 131 shown in the figure is only an example, and the specific number can be determined according to actual needs. The number of hydrogen production and storage modules 500 can also be adjusted according to actual conditions. Each hydrogen production and storage module 500 is equipped with corresponding power and hydrogen transmission pipelines to ensure coordinated operation between multiple modules.

[0043] The first support component 130 and the hydrogen production and storage module 500 work together as a support structure for the deck 110, providing support for the deck 110, improving the structural stability of the deck 110, reducing the possibility of structural deformation of the deck 110 supporting the hydrogen production and storage module 500, and improving safety. The hydrogen production and storage module 500 supports the deck 110 while producing and storing hydrogen, without significantly increasing the number of support columns 131, saving space between any two adjacent decks 110, facilitating the installation of the hydrogen production and storage module 500, and achieving functional integration and structural simplification. At the same time, the hydrogen production and storage capacity can be increased by increasing the number of hydrogen production and storage modules 500.

[0044] In some specific embodiments of this application, such as Figure 6 As shown, the hydrogen production and storage module 500 includes a housing 510 and a hydrogen production and storage module assembly 520, with the assembly located inside the housing 510. The housing 510 has multiple vent holes 511. Specifically, the housing 510 is made of high-strength steel (such as martensitic steel, duplex steel, etc.), aluminum alloy, or magnesium alloy, or other high-strength materials to improve its structural strength and rigidity, thereby providing good support. The housing 510 can be containerized, with the hydrogen production and storage module assembly 520 placed inside. To reduce the safety hazards caused by hydrogen accumulation, multiple vent holes 511 are provided on the housing 510. Specifically, multiple vent holes 511 can be spaced apart on one side of the housing 510, or spaced apart on different sides of the housing 510, to improve safety performance.

[0045] In some specific embodiments of this application, such as Figures 1-4 As shown, the platform body 100 includes a third support component 150, which is disposed between the float 120 and the support deck 113. The third support component 150 includes a plurality of spaced columns 151. The columns 151 are arranged to share the weight of the platform body 100 and withstand the impact of waves from the sea surface, ensuring the balance and safety of the platform body 100.

[0046] Specifically, the number of columns 151 can be three, four, five, or more, and the specific number can be determined according to actual needs. When there are three columns 151, it is preferable that the three columns 151 are arranged in a triangle, with the top of each column 151 connected to the support deck 113 and the bottom of each column 151 connected to the float 120. The triangular arrangement can improve the support stability of the third support component 150 and ensure the support stability of each deck 110. When there are four columns 151, it is preferable that the columns 151 are distributed at four corners, with the top of each column 151 connected to the support deck 113 and the bottom of each column 151 connected to the float 120. The four-corner distribution can form a stable rectangular support surface, thereby firmly supporting the entire platform on the seabed and ensuring the support stability of each deck 113.

[0047] When the number of pillars 151 is five, such as Figure 1 and Figure 2 As shown, the third support component 150 includes a central column 1511 and multiple side columns 1512 located around the central column 1511. The side columns 1512 are distributed in a four-corner configuration. The central column 1511 is preferably located at the center of the support deck 113. In this configuration, the central column 1511 and the side columns 1512 work together. The central column 1511 bears the load in the central area of ​​the deck 110, which can improve the load-bearing capacity of the deck 110, reduce the possibility of deformation of the deck 110, increase the stability of the deck 110, prevent the deck 110 from undergoing permanent deformation due to load, and ensure the stability of the offshore hydrogen production platform.

[0048] In some specific embodiments of this application, such as Figures 1-4 As shown, for each column 1511, along the axial direction of the column 151, from the direction closer to the support deck 113 to the direction farther away from the support deck 113, the radial dimension of the column 151 gradually increases. In other words, the column 151 is narrower at the top and wider at the bottom. This method can lower the overall center of gravity of the platform body 100, optimize the waterline moment of inertia, and enhance the restoring moment.

[0049] In some specific embodiments of this application, the float 120 and each of the side pillars 1512 are provided with ballast compartments, meaning that the interiors of the float 120 and each side pillar 1512 are hollow structures. By increasing or decreasing the mass of ballast water in the ballast compartments, the center of gravity of the platform body 100 is adjusted. Furthermore, the offshore hydrogen production platform includes a mooring system connected to the float 120. Specifically, the mooring system can be a tensioned single-point mooring system or a multi-point mooring system. The ballast compartments cooperate with the mooring system to achieve stable balance of the platform body 100.

[0050] In some specific embodiments of this application, such as Figure 1 , Figure 2 and Figure 4 As shown, a fourth support assembly 160 is provided between the float 120 and the support deck 113. The fourth support assembly 160 includes at least one support rod 161, and the wave energy generation module 400 is disposed on the support rod 161, forming a wave energy generation module mounting rod. Specifically, the number of support rods 161 can be one, two, or more, and the number of wave energy generation modules 400 can match the number of support rods 161, or the number of wave energy generation modules 400 can be less than the number of support rods 161. The top of each support rod 161 is connected to the support deck 113, and the bottom of each support rod 161 is connected to the float 120, specifically by welding or flange connection. The figure shows that there are four support rods 161, and the wave energy generation modules 400 are correspondingly arranged on the support rods 161. Each support rod 161 in the fourth support component 160 provides support for the deck 110 on the one hand, and provides an installation foundation for the wave energy power generation module 400 on the other hand, playing a dual role. There is no need to set up an additional installation structure for the wave energy power generation module 400. By directly setting the wave energy power generation module 400 on the support rod 161, the extra space occupied by setting up a separate installation structure is avoided, which is conducive to the compact design of the platform body 100, improves the space utilization rate, and can achieve functional integration, structural simplification, and reduction of overall cost.

[0051] The offshore hydrogen production platform disclosed in this application uses a first support component 130, a hydrogen production and storage module 500 (a second support component), a third support component 150, and a fourth support component 160 to work together to provide support for each deck 110, ensuring the structural stability of each deck 110. This provides an installation platform for each power generation module and the hydrogen production and storage module 500, enabling hydrogen production and storage. Specifically, the wave energy power generation module 400 can be an oscillating float-type wave energy power generation device. When waves pass over the platform body 100, the wave energy power generation module 400 can absorb the wave energy, reducing the overall heave response of the platform body 100. Simultaneously, the wave energy power generation module 400 can work in conjunction with the wind power generation module 200 and the photovoltaic power generation module 300 to provide a stable and continuous power supply to the hydrogen production and storage module 500, improving hydrogen production efficiency, reducing the number of shutdowns of the hydrogen production and storage module 500, and ensuring the stable operation of the hydrogen production and storage module 500.

[0052] In some specific embodiments of this application, such as Figure 2 , Figure 4 and Figure 5As shown, at least one bottom deck 112 is equipped with a hydrogen delivery interface 114, and each hydrogen production and storage module 500 is connected to the hydrogen delivery interface 114 via pipelines. Specifically, the hydrogen production and storage module assembly 520 includes a seawater extraction unit, an electrolysis water hydrogen production unit, a separation, purification, and compression unit, and an energy storage unit. The hydrogen production process is as follows: First, seawater is extracted by the seawater extraction unit and sent to the electrolysis water hydrogen production unit for electrolysis. The hydrogen produced by electrolysis is separated, purified, and compressed by the separation, purification, and compression unit before being sent to the energy storage unit for storage. The hydrogen delivery interface 114 is located in the aforementioned energy storage unit. When the hydrogen storage reaches a certain amount, it can be transported by connecting a transport ship to the hydrogen delivery interface 114. Specifically, one or more hydrogen delivery interfaces 114 can be provided. Hydrogen delivery interfaces 114 can be provided on each deck 110 where the hydrogen production and storage modules 500 are located to facilitate the transportation of hydrogen and realize the external delivery of hydrogen.

[0053] In some specific embodiments of this application, such as Figure 1 and Figure 2 As shown, the wind power generation module 200 includes a tower 210 and a wind turbine 220. The tower 210 extends through the top deck 111 and the bottom decks 112 of each level, and is connected to the support deck 113. The wind turbine 220 is located at the top of the tower 210. Preferably, the wind turbine 220 includes three blades. The tower 210 is preferably located at the center of the deck 110 to ensure the stability of the entire platform.

[0054] In some specific embodiments of this application, an elevator 140 is provided between each deck 110 for the transfer of personnel and equipment.
