Description

Technical Field

[0001] This invention relates to the field of energy supply for marine computing centers, specifically to an integrated marine computing center system that utilizes ocean energy to achieve hydrogen storage and power supply. Background Technology

[0002] In recent years, with the rapid development of artificial intelligence, big data, and cloud computing technologies, the demand for computing power has exploded. Traditional terrestrial computing centers face numerous limitations during construction: first, land resources are becoming increasingly scarce, making data center site selection more difficult; second, the pressure on power supply is enormous, and the energy consumption of large-scale computing has become a bottleneck restricting the development of the computing power industry; and third, the energy consumption of cooling systems remains high, with traditional air-cooling or water-cooling solutions requiring a large amount of electricity for temperature control, further exacerbating the energy supply and demand contradiction.

[0003] On the other hand, the ocean possesses abundant renewable green energy resources, including wind and wave energy, making it an important carrier for the large-scale development and utilization of renewable energy. Against this backdrop, the proposal to locate computing centers in the marine environment and construct marine computing centers has emerged. Marine computing centers have the following advantages: First, they can fully utilize the abundant green energy resources at sea, such as wind and wave energy, to generate electricity locally, effectively alleviating the power supply pressure on the terrestrial power grid; second, they can directly utilize seawater as a cooling medium, significantly reducing the energy consumption and construction costs of the heat dissipation system; and third, they overcome the land use restrictions of land-based site selection, offering broad development potential.

[0004] However, the development of existing marine computing centers still faces numerous technical bottlenecks. First, due to the influence of the marine environment and extreme weather, the generation of green electricity such as wind and wave power exhibits significant intermittency and volatility, making it difficult to provide a stable and continuous power supply. Second, existing energy storage technologies cannot efficiently store green electricity in a long-term storage format, resulting in insufficient energy utilization, severe wind and wave curtailment, and difficulty in achieving true self-sufficiency and off-grid operation. Third, marine computing centers generate a large amount of waste heat during operation, which current solutions typically release directly into the environment without effective recycling, leading to energy waste. Furthermore, the stability of the power supply system has not been fundamentally resolved; any power outage or voltage fluctuation will directly affect the normal operation of computing equipment, causing incalculable data security risks and economic losses.

[0005] Therefore, developing a system that can integrate marine green energy capture, energy storage and regulation, and waste heat recovery and utilization to achieve fully self-sufficient operation of marine computing centers, solving the above-mentioned defects of existing technologies, and promoting the sustainable development of the marine green energy industry has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides an integrated marine computing center system that utilizes ocean energy to achieve hydrogen storage and power supply.

[0007] The technical solution adopted in this invention is as follows: An integrated marine computing center system utilizing ocean energy for hydrogen storage and power supply is provided, comprising: The marine computing center uses liquid cooling to cool its internal chips, and cooling water flows out after cooling. The seawater heat exchange module is connected to the ocean computing center and includes a seawater heat exchanger.

The cooling water is cooled and flows back to the ocean computing center to enter the next heat exchange cycle. The temperature control module has its input end connected to the output end of the seawater heat exchange module, and regulates the temperature of the seawater after heat exchange and heating to maintain it within a set temperature range of 50℃-70℃. The membrane distillation module has its input end connected to the output end of the temperature control module. It performs membrane distillation treatment on the temperature-controlled seawater to separate it into fresh water and concentrated seawater. The concentrated seawater is directly discharged into the ocean. The SOEC water electrolysis module has its input end connected to the fresh water output end of the membrane distillation module. It uses the fresh water as raw material to perform water electrolysis, producing hydrogen and oxygen. The oxygen is directly discharged into the environment. A hydrogen energy storage module, the input end of which is connected to the hydrogen output end of the SOEC water electrolysis module, to store the hydrogen produced therefrom; The liquefaction module includes a liquid hydrogen module, which is connected to the hydrogen energy storage module.

The SOFC fuel cell module has its input end connected to the output end of the hydrogen energy storage module, receives the hydrogen output by the hydrogen energy storage module, and converts its chemical energy into electrical energy to power other electrical equipment in the system except for the SOEC water electrolysis module. The hydrogen energy storage and control module is connected to the hydrogen energy storage module and the liquid hydrogen module, and is used to regulate the storage and replenishment of hydrogen between the hydrogen energy storage module and the liquid hydrogen module according to the gas pressure in the hydrogen energy storage module.

The hydrogen inlet is connected to the hydrogen output terminal of the SOEC water electrolysis module; the hydrogen outlet is connected to the input terminal of the SOFC fuel cell module; and the hydrogen replenishment port is connected to a liquid hydrogen module for replenishing the hydrogen energy storage tank after the liquid hydrogen module vaporizes the liquid hydrogen. A hydrogen compressor is installed between the hydrogen storage tank and the liquid hydrogen module, and a one-way valve, a first pressure reducing valve and a pneumatic valve are installed sequentially between the hydrogen storage tank and the hydrogen compressor. A second pressure reducing valve is also installed before the hydrogen outlet.

[0011] Preferably, the liquid hydrogen module includes a precooling module, a first refrigerator, a liquid hydrogen storage tank, and a throttling valve disposed between the first refrigerator and the liquid hydrogen storage tank; the first refrigerator has a cold head heat exchanger.

[0012] Preferably, the liquid nitrogen module includes a liquid nitrogen storage tank and a second refrigeration unit disposed on the liquid nitrogen storage tank, the second refrigeration unit being used to liquefy the continuously heated and evaporated nitrogen gas into liquid nitrogen.

[0013] Preferably, the liquid nitrogen storage tank supplies liquid nitrogen to the precooling module as a precooling medium for the hydrogen passing through the precooling module.

[0014] Preferably, the green electricity module includes: Superconducting wind power generation module, used to convert wind energy into electrical energy; Superconducting wave energy generation module, used to convert wave energy into electrical energy; Photovoltaic solar power generation modules are used to convert solar energy into electrical energy; Both the superconducting wind power generation module and the superconducting wave power generation module include a rotor, on which a superconducting coil assembly is wound. The superconducting coil assembly is equipped with a liquid nitrogen cooling structure. The liquid nitrogen in the liquid nitrogen module cools the superconducting coil assembly through the liquid nitrogen cooling structure, putting it into a superconducting state.

[0015] Preferably, the hydrogen energy storage control module is connected to the hydrogen energy storage module and the liquid hydrogen module to form a refrigeration cycle loop and a gas replenishment loop; The refrigeration cycle circuit is composed of the hydrogen storage tank, one-way valve, first pressure reducing valve, pneumatic valve, hydrogen compressor, and the precooling module, first refrigerator, throttle valve and liquid hydrogen storage tank in the liquid hydrogen module connected in sequence. The gas replenishment circuit is sequentially equipped with a cryogenic pneumatic valve, a regenerator, a vaporizer, and a rewarmer. The regenerator is wound around the outer wall of the inner liner of the liquid nitrogen storage tank, and the output end of the rewarmer is connected to the hydrogen gas replenishment port.

[0016] Preferably, the control modes of the hydrogen energy storage control module include: Start-up mode selection: When the system starts up, the initial operating valve state is selected according to the initial gas pressure value P in the hydrogen storage tank: when P > P1, it enters the liquefaction storage valve state; when P < P4, it enters the liquid hydrogen replenishment valve state; when P4 ≤ P ≤ P1, it enters the hydrogen direct supply valve state; where P1 > P4. Operating mode switching: After the system completes the start-up mode selection, the system cycles between mode A and mode B as the gas pressure P in the hydrogen storage tank changes.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. Achieved self-sufficiency in energy supply for the marine computing center. This invention captures wind, wave, and solar energy from the ocean using a green electricity module, converting it into electricity to power the SOEC water electrolysis module. The system continuously processes seawater through a membrane distillation module to produce fresh water. This fresh water is then electrolyzed by the SOEC water electrolysis module to produce hydrogen. The hydrogen is then used as the energy feedstock for the SOFC fuel cell module, converting hydrogen energy into electricity to power other electrical equipment in the system besides the SOEC water electrolysis module. This forms a virtuous cycle supply system of "seawater desalination - electrolysis hydrogen production - hydrogen power generation - self-sufficient power supply," eliminating the need for external connection to the land power grid. This effectively solves the power supply problem of the marine computing center and significantly reduces its long-term operating electricity costs.

[0018] 2. Utilizing seawater for cooling and preheating of the marine computing center system. This invention uses seawater as a cooling medium to exchange heat and lower the temperature of the marine computing center. The cold source supply is sufficient and stable, effectively ensuring the operating temperature of the marine computing center. Furthermore, after the seawater passes through the marine heat exchanger, it absorbs heat and rises in temperature. The temperature control module adjusts the temperature to meet the requirements of the membrane distillation module, achieving synergistic utilization of seawater cooling and preheating, saving the additional energy consumption required for equipment cooling and seawater preheating.

[0019] 3. An integrated design for hydrogen storage and liquid hydrogen replenishment has been achieved. This invention realizes the supply, storage, and replenishment of hydrogen by setting up a hydrogen energy storage module and a liquid hydrogen module, designing a refrigeration cycle loop and a replenishment loop, and configuring a hydrogen energy storage control module: when the hydrogen supply is sufficient, excess hydrogen is liquefied and stored in a liquid hydrogen storage tank to achieve hydrogen energy reserve; when the hydrogen supply is insufficient, the liquid hydrogen in the liquid hydrogen storage tank is vaporized and replenished to the hydrogen energy storage tank, realizing on-demand allocation of hydrogen energy. Through this integrated design, a continuous and sufficient supply of hydrogen raw materials required by the SOFC fuel cell module is ensured, providing energy security for the continuous and stable operation of the entire marine computing center system.

[0020] 4. The liquid nitrogen module enables dual-path cooling. As a closed-loop system, the liquid nitrogen it generates cools the superconducting coils in both the superconducting wind power and superconducting wave power modules, maintaining their superconductivity. Simultaneously, it supplies liquid nitrogen to the pre-cooling module in the liquid hydrogen module as a pre-cooling medium, participating in the hydrogen pre-cooling process within the refrigeration cycle. Working in conjunction with the pre-cooling module, it completes hydrogen liquefaction, ensuring sufficient cooling capacity for liquid hydrogen storage.

[0021] Meanwhile, the regenerator is wrapped around the outer wall of the inner liner of the liquid nitrogen storage tank in the liquid nitrogen module. When liquid hydrogen in the gas replenishment circuit flows through the regenerator, it exchanges heat with the outer wall of the liquid nitrogen storage tank, thus raising its temperature. This design eliminates the need for an additional heat source or electric heating device, effectively reducing the energy consumption of the gas replenishment circuit. Simultaneously, during the process of heating and vaporizing liquid hydrogen, the liquid nitrogen storage tank releases heat to the liquid hydrogen, lowering its own temperature and effectively suppressing liquid nitrogen evaporation. This reduces the load on the nitrogen liquefaction unit's chiller, decreases refrigeration energy consumption, and improves the overall operating efficiency of the liquid nitrogen cooling system.

[0022] 5. Zero carbon emissions, green and environmentally friendly. The energy input of this invention is entirely from marine renewable energy sources. The hydrogen production feedstock is seawater, and the electrolysis products are hydrogen and oxygen. The hydrogen storage and replenishment process does not consume any fossil fuels and does not produce any pollutants, achieving true zero carbon emissions and meeting the global carbon neutrality goal and the development requirements of green computing centers.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the present invention will be further described in detail below with reference to the specific accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, an integrated marine computing center system utilizing ocean energy for hydrogen storage and supply is provided, comprising a marine computing center 1, a seawater heat exchange module 2, a temperature control module 3, a membrane distillation module 4, an SOEC water electrolysis module 5, a hydrogen energy storage module 6, a liquefaction module 7, an SOFC fuel cell module 8, a hydrogen energy storage regulation module 9, and a green electricity module 10. Wherein: Ocean Computing Center 1 is a Hydrogen Energy Artificial Intelligence Infrastructure (HAI Infra), serving as the computing center for AI model training, inference, and large-scale data processing, and is a prerequisite for supporting AI operations. Statistics show that when the chip temperature within the Ocean Computing Center reaches 70°C–80°C, its performance decreases by nearly 50% for every additional 10°C increase. Therefore, typically, about 30%–50% of the facility's power supply is used for cooling. This invention employs liquid cooling to cool its internal chips, with cooling water flowing out after cooling.

[0029] The seawater heat exchange module 2 is connected to the ocean computing center 1 and includes a seawater heat exchanger 21 and a first temperature measuring module 22 installed on the cooling water circuit. The external ambient temperature seawater and the cooling water flowing out of the ocean computing center 1 exchange heat through the seawater heat exchanger 21 and are heated and output. After the cooling water is cooled down, it flows back to the ocean computing center 1 and enters the next heat exchange cycle. The first temperature measuring module 22 is used to measure the temperature of the cooling water flowing back to the ocean computing center 1 circuit in real time.

[0030] The input end of the temperature control module 3 is connected to the output end of the seawater heat exchange module 2 to regulate the temperature of the seawater after heat exchange and heating, keeping it within the range of 50℃-70℃. This temperature range is the temperature range required for the operation of the membrane distillation module 4. A second temperature measuring module 31 is set in front of the input end of the temperature control module 3. The second temperature measuring module 31 is used to measure the temperature of the seawater before it enters the temperature control module 3 after heat exchange and heating in real time.

[0031] The input end of the membrane distillation module 4 is connected to the output end of the temperature control module 3. The seawater after temperature regulation is treated by membrane distillation and separated into fresh water and concentrated seawater. The concentrated seawater is directly discharged into the ocean, while the fresh water enters the SOEC water electrolysis module 5 for electrolysis reaction.

[0032] SOEC water electrolysis module 5 uses fresh water as raw material to perform water electrolysis, producing hydrogen and oxygen. The oxygen is directly discharged into the environment, while the hydrogen is transported to hydrogen energy storage module 6 for storage.

[0033] The green power module 10 is connected to the SOEC water electrolysis module 5 to supply it with power. Specifically, the green power module 10 includes: a superconducting wind power generation module 101, used to convert wind energy on the ocean into electrical energy; a superconducting wave energy generation module 102, used to convert wave energy on the ocean into electrical energy; and a photovoltaic solar power generation module 103, which can actually be a photovoltaic panel, used to convert solar energy on the ocean into electrical energy. Both the superconducting wind power generation module 101 and the superconducting wave energy generation module 102 include rotors in their structure, on which superconducting coils are wound. The superconducting coils need to be maintained in a superconducting state to operate.

[0034] The input end of the hydrogen energy storage module 6 is connected to the hydrogen output end of the SOEC water electrolysis module 5, receives hydrogen from the electrolysis product of the SOEC water electrolysis module 5, and delivers the hydrogen to the SOFC fuel cell module 8.

[0035] like Figure 2As shown, the hydrogen energy storage module 6 includes a hydrogen storage tank 61, with a hydrogen inlet 62, a hydrogen replenishment port 63, and a hydrogen outlet 64 disposed on the hydrogen storage tank 61. The hydrogen inlet 62 is connected to the hydrogen output terminal of the SOEC water electrolysis module 5 and is used to receive the product hydrogen from the electrolysis of the SOEC water electrolysis module 5 and store it in the hydrogen storage tank 61; the hydrogen outlet 64 is connected to the input terminal of the SOFC fuel cell module 8.

[0036] The liquefaction module 7 includes a liquid hydrogen module 71 and a liquid nitrogen module 72.

[0037] A hydrogen compressor 65 is installed between the hydrogen storage tank 61 and the liquid hydrogen module 71. A one-way valve 66, a first pressure reducing valve 67 and a pneumatic valve 68 are installed sequentially between the hydrogen storage tank 61 and the hydrogen compressor 65. A second pressure reducing valve 69 is also installed before the hydrogen outlet 64.

[0038] like Figure 2 As shown, the liquid hydrogen module 71 includes a precooling module 711, a first refrigerator 712, and a liquid hydrogen storage tank 713 arranged in sequence, and a throttle valve 714 disposed between the first refrigerator 712 and the liquid hydrogen storage tank 713, wherein the first refrigerator 712 has a cold head heat exchanger 7121.

[0039] The liquid nitrogen module 72 is a closed-loop system, including a liquid nitrogen storage tank 721 and a second chiller 722 installed on the liquid nitrogen storage tank 721. The liquid nitrogen storage tank 721 is connected to the green electricity module 10 and cools the superconducting coil groups in the superconducting wind power generation module 101 and superconducting wave power generation module 102 within the green electricity module 10 by supplying liquid nitrogen, thus maintaining their superconducting state. At the same time, the liquid nitrogen storage tank 721 supplies liquid nitrogen to the precooling module 711 in the liquid hydrogen module 71 as a precooling medium for the hydrogen flowing through the precooling module 711.

[0040] The input terminal of the SOFC fuel cell module 8 is connected to the output terminal of the hydrogen energy storage module 6, receives the hydrogen output by the hydrogen energy storage module 6, and converts its chemical energy into electrical energy to power other electrical equipment in the system except for the SOEC water electrolysis module 5.

[0041] like Figure 2 As shown, the hydrogen energy storage control module 9 is connected to the hydrogen energy storage module 6 and the liquid hydrogen module 71, and is used to regulate the storage and replenishment of hydrogen between the hydrogen energy storage module 6 and the liquid hydrogen module 71 according to the gas pressure inside the hydrogen energy storage module 6. The hydrogen energy storage control module 9, hydrogen energy storage module 6, and liquid hydrogen module 71 are connected to form a refrigeration cycle loop and a gas replenishment loop; wherein: The refrigeration cycle circuit is composed of the hydrogen storage tank 61, the one-way valve 66, the first pressure reducing valve 67, the pneumatic valve 68, the hydrogen compressor 65, and the precooling module 711, the first refrigerator 712, the throttle valve 714 and the liquid hydrogen storage tank 713 in the liquid hydrogen module 71 connected in sequence. The gas replenishment circuit is sequentially equipped with a cryogenic pneumatic valve 73, a regenerator 74, a vaporizer 75, and a reheater 76. The regenerator 74 is wound around the outer wall of the inner liner of the liquid nitrogen storage tank 721. The output end of the reheater 76 is connected to the hydrogen gas replenishment port 63, which is used by the liquid hydrogen module 71 to vaporize the liquid hydrogen and replenish it to the hydrogen energy storage tank 61.

[0042] like Figure 3 As shown, the system described in this application has the following three valve states: Liquid hydrogen replenishment valve status: Pneumatic valve 68 is closed, cryogenic pneumatic valve 73 is open, and liquid hydrogen stored in liquid hydrogen storage tank 713 enters the replenishment circuit. The regenerator 74, vaporizer 75, and rewarmer 76 in the replenishment circuit reheat, vaporize, and rewarm the liquid hydrogen to room temperature in sequence, and then enter the hydrogen storage tank 61 through hydrogen replenishment port 63.

[0043] Hydrogen direct supply valve status: Pneumatic valve 68 is closed, cryogenic pneumatic valve 73 is closed, and hydrogen storage tank 61 directly and independently supplies hydrogen to the SOFC fuel cell module.

[0044] Liquefaction storage valve status: Pneumatic valve 68 is open, cryogenic pneumatic valve 73 is closed, and the first pressure reducing valve 67 is set to a pressure value not exceeding 80% of the maximum return gas pressure of the hydrogen compressor 65. Hydrogen output from hydrogen storage tank 61 is compressed by hydrogen compressor 65 to form high-temperature, high-pressure hydrogen. This high-temperature, high-pressure hydrogen is then cooled by seawater to form room-temperature, high-pressure hydrogen. This room-temperature, high-pressure hydrogen is pre-cooled to near 80K by pre-cooling module 711, then cooled to below the throttling temperature by the cold head heat exchanger 7121 of the first refrigeration unit 712. After throttling by throttling valve 714, a gas-liquid mixture is obtained and enters liquid hydrogen storage tank 713. The gas-liquid mixture undergoes gas-liquid separation within liquid hydrogen storage tank 713. The separated liquid hydrogen is stored in liquid hydrogen storage tank 713. The separated low-temperature, low-pressure hydrogen is reheated by pre-cooling module 711 and mixed with hydrogen from hydrogen storage tank 61 at the inlet of hydrogen compressor 65 for recompression, forming a refrigeration cycle.

[0045] like Figure 3 As shown, the control modes of the hydrogen energy storage control module 9 include start-up mode selection and operation mode switching, specifically: Startup mode selection: When the system starts up, the initial operating valve state is selected based on the comparison between the initial gas pressure value P in the hydrogen storage tank 61 and the preset values ​​P1 and P4. This selection is only performed once each time the system is started up. When P > P1, the liquefaction storage valve enters the state. When P < P4, the liquid hydrogen replenishment valve is activated. When P4≤P≤P1, the system enters the direct hydrogen supply valve state. Where P1 > P4; In the embodiment described below, the preset values ​​P1 > P2 > P3 > P4. P1 to P2 constitute the start-stop hysteresis interval of mode B, and P3 to P4 constitute the start-stop hysteresis interval of mode A. The hysteresis interval refers to the different pressure thresholds triggered when the operating state of equipment structures changes during system operation. That is, when the pressure drops to a lower threshold (such as P2) or rises to a higher threshold (such as P3), the operation of a certain equipment structure is shut down or started. This hysteresis design effectively avoids frequent start-stop of actuators such as hydrogen compressors and pneumatic valves caused by pressure fluctuations in the hydrogen storage tank 61 around a single threshold, thereby improving the stability of system operation and the service life of equipment.

[0046] Operating mode switching: After the system completes the selection of the start valve status, as the gas pressure P inside the hydrogen storage tank 61 changes, the system enters a cyclical switching between two modes, A and B. Specifically, mode A and its internal cyclic switching, and mode B and its internal cyclic switching are described as follows: Mode A: Initially, the system is in the liquid hydrogen replenishment valve state. At this time, the hydrogen supply in hydrogen storage tank 61 is insufficient, and the liquid hydrogen stored in liquid hydrogen storage tank 713 is vaporized and replenished to hydrogen storage tank 61. Further, when the gas pressure P in hydrogen storage tank 61 > P3, the system enters the direct hydrogen supply valve state, where hydrogen storage tank 61 supplies hydrogen solely to SOFC fuel cell module 8. Alternatively, when the gas pressure P in hydrogen storage tank 61 < P4, the system enters the liquid hydrogen replenishment valve state. The system repeatedly cycles between the liquid hydrogen replenishment valve state and the direct hydrogen supply valve state.

[0047] Mode B: The system initially operates in the liquefaction storage valve state. In this state, hydrogen storage tank 61 supplies hydrogen to the SOFC fuel cell module 8. Simultaneously, excess hydrogen in hydrogen storage tank 61 is liquefied and stored in liquid hydrogen storage tank 713. Further, when the gas pressure P in hydrogen storage tank 61 < P2, the system enters the direct hydrogen supply valve state, where hydrogen storage tank 61 directly and solely supplies hydrogen to the SOFC fuel cell module 8. Alternatively, when the gas pressure P in hydrogen storage tank 61 > P1, the system enters the liquefaction storage valve state. The system cycles repeatedly between these two states.

[0048] The system described in this application operates as follows under the control of the hydrogen energy storage and regulation module 9: Operating Scenario 1: If the system starts up with the hydrogen direct supply valve selected, the hydrogen storage tank 61 supplies hydrogen to the SOFC fuel cell module alone. As the system runs, when the gas pressure in the hydrogen storage tank 61 is less than P4, the system enters mode A. When P is greater than P1, the system automatically switches to mode B. Furthermore, when P is less than P4, the system switches back to mode A.

[0049] Alternatively, if the system starts with the hydrogen direct supply valve selected, as the system runs, when the gas pressure P in the hydrogen storage tank 61 is greater than P1, the system enters mode B; when P is less than P4, the system automatically switches to mode A; furthermore, when P is greater than P1, the system switches back to mode B.

[0050] Based on this pattern, the system will cycle between mode A and mode B.

[0051] Scenario 2: If the system starts with the liquefied storage valve selected, it will enter mode B. When P < P4, the system will automatically switch to mode A. When P > P1, the system will switch back to mode B. Following this pattern, the system will cycle between mode A and mode B.

[0052] Scenario 3: If the system starts with the liquid hydrogen replenishment valve in the selected state, the system will enter mode A. When P > P1, the system will automatically switch to mode B; when P < P4, the system will switch back to mode A. Following this pattern, the system will cycle between mode A and mode B.

[0053] Regardless of whether the system starts up in any of the following states: liquid hydrogen replenishment valve state, liquefaction storage valve state, or direct hydrogen supply valve state, the system will continuously switch between mode A and mode B in real time according to the gas pressure P in the hydrogen storage tank 61 until the system is shut down.

[0054] The working principle of this invention is as follows: When the marine computing center 1 starts up, the ambient temperature seawater and the cooling water flowing out after being liquid cooled by the marine computing center 1 exchange heat at the seawater heat exchanger 21. After the heat exchange, the cooling water cools down and flows back to the marine computing center 1 through the cooling water loop to continue the next heat exchange cycle. After the heat exchange, the ambient temperature seawater heats up and is transported to the temperature control module 3. The temperature control module 3 regulates its temperature between 50℃ and 70℃. The temperature-controlled seawater enters the membrane distillation module 4, where it undergoes membrane distillation treatment to separate fresh water and concentrated seawater. The concentrated seawater is discharged into the ocean, and the fresh water enters the SOEC water electrolysis module 5. The SOEC water electrolysis module 5 is powered by a green electricity module 10 consisting of a superconducting wind power generation module 101, a superconducting wave power generation module 102, and a photovoltaic solar power generation module 103. At the SOEC water electrolysis module 5, fresh water is electrolyzed into hydrogen and oxygen. The oxygen is released into the environment, while the hydrogen is transported to the hydrogen storage module 6 for storage. Specifically, the hydrogen is stored in a hydrogen storage tank 61. When the storage capacity of the hydrogen storage tank 61 reaches its maximum, the excess hydrogen obtained from electrolysis is liquefied by the liquefaction module 7 and stored in a liquid hydrogen storage tank 713. The hydrogen storage tank 61 directly supplies hydrogen to the SOFC fuel cell module 8, which converts the hydrogen energy into electrical energy to power the marine computing center 1 and other electrical equipment in the system besides the SOEC water electrolysis module 5.

[0055] The hydrogen energy storage control module 9 is used to regulate the storage and replenishment of hydrogen between the hydrogen energy storage module 6 and the liquid hydrogen module 71 based on the gas pressure P in the hydrogen energy storage tank 61. The change in the gas pressure P reflects the change in the electrical load of the equipment powered by the SOFC fuel cell module 8. When the system starts up, it selects to enter one of the following states based on the initial gas pressure in the hydrogen energy storage tank 61: liquefaction storage valve state, liquid hydrogen replenishment valve state, and direct hydrogen supply valve state. During operation, the system cycles between mode A and mode B to ensure that the SOFC fuel cell module obtains a continuous and stable hydrogen supply, providing sufficient power guarantee for the continuous and reliable operation of the entire marine computing center system.

[0056] The above description is only a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited thereto. For those skilled in the art, any equivalent substitutions or obvious modifications made based on the content and principles of the present invention should be included within the scope of protection of the present invention.
