[0002] With increasing global focus on sustainable development and addressing climate change, the development and utilization of renewable energy has become central to energy strategies. Among various renewable energy sources, wind power holds a significant position due to its abundant resources and clean, pollution-free characteristics. In particular, the location of wind turbines is continuously expanding offshore in order to access more stable and abundant wind resources. Offshore wind farms typically have higher wind speeds and less turbulence than onshore wind farms, enabling them to achieve higher capacity factors and more stable power output.

[0003] However, due to their long distance from shore, large power generation capacity, and the inherent intermittent and fluctuating nature of wind energy, the effective utilization of wind energy and long-distance power transmission have become key technological bottlenecks and challenges restricting their large-scale development. This could lead to wind curtailment, resulting in significant energy waste and economic losses. Therefore, it is urgent to modify wind turbine outputs to be more flexible and adjustable to achieve efficient energy utilization. Summary of the Invention

[0036] Preferably, the pretreatment boiler 103 is equipped with a seawater desalination device, which uses reverse osmosis membrane technology or multi-stage flash evaporation technology to desalinate seawater.

[0037] The high-temperature co-electrolysis reactor 104 includes at least one high-temperature co-electrolysis reactor 140 for converting the carbon dioxide and water vapor into syngas under the drive of electrical energy, wherein the syngas includes hydrogen and carbon monoxide.

[0038] Preferably, the high-temperature co-electrolysis reaction vessel 140 includes a shell and a cavity, wherein:

[0039] The outer shell adopts a three-layer composite structure, consisting of a structural layer, an insulation layer, and a corrosion-resistant layer from the outermost layer to the innermost layer. The structural layer is the load-bearing skeleton of the high-temperature co-electrolysis reaction vessel. The insulation layer is used to maintain the internal temperature of the high-temperature co-electrolysis reaction vessel within a custom temperature range when it is not in operation. The corrosion-resistant layer is in direct contact with the high-temperature reaction medium inside the cavity and is used to prevent the high-temperature reaction medium from corroding the outer shell.

[0040] A temperature / pressure sensor is installed inside the cavity, wherein the temperature / pressure sensor is used to collect the temperature / pressure inside the cavity in real time to monitor the temperature / pressure during the preparation of syngas inside the cavity;

[0041] The top of the outer casing is provided with an anode outlet and a cathode outlet communicating with the cavity, along with an anode, a cathode, a pressure relief valve, and a heating rod circuit. The bottom of the outer casing is provided with an anode inlet and a cathode inlet communicating with the cavity. The anode inlet and anode outlet are used for the circulation of anode gas, the cathode inlet is used for the input of carbon dioxide and water vapor, and the cathode outlet is used for the output of syngas. An electrochemical reaction zone is formed between the anode and the cathode, allowing water vapor and carbon dioxide to undergo a co-electrolysis reaction driven by electrical energy to generate syngas.

[0043] Preferably, a permeable membrane is further disposed between the anode and cathode in the cavity for gas separation and to promote the permeation of relevant gas components.

[0044] Figure 2 This is a schematic diagram of the reaction vessel in a high-temperature co-electrolysis apparatus according to a preferred embodiment of the present invention. Figure 2 As shown, the reaction vessel 140 in the high-temperature co-electrolysis apparatus of this preferred embodiment includes a shell 1402 and a cavity 1413 formed by the internal space of the shell 1402, and also includes an anode inlet 1401, an anode outlet 1403, an anode 1404, a heating rod circuit 1405, a pressure relief valve 1406, a cathode 1407, a cathode outlet 1408, a drying device 1409, a cathode inlet 1410, a temperature / pressure sensor 1411, and a permeation membrane 1412.

[0045] Figure 3 This is a schematic diagram of the outer shell of the reaction vessel in a high-temperature co-electrolysis apparatus according to a preferred embodiment of the present invention. Figure 3As shown, the outer shell 1402 consists of a structural layer 1402A, an insulation layer 1402B, and a corrosion-resistant layer 1403C, arranged from the outermost to the innermost layer. The structural layer 1402A forms the load-bearing framework of the entire container. This layer is made of a high-strength, high-toughness metal alloy, such as special stainless steel or nickel-based alloy. Its thickness is precisely calculated and optimized based on the container's dimensions, internal working pressure, and stresses caused by the external environment (such as wind, waves, and vibration), typically around several centimeters, to ensure the structural integrity and safety of the device under extreme conditions. This layer also possesses good welding and processing properties for ease of manufacturing and assembly. The insulation layer 1402B, located between the structural layer 1402A and the corrosion-resistant layer 1402C, is the key core layer for achieving efficient insulation of the device. This layer is made of nanoporous insulation materials with extremely low thermal conductivity and excellent high-temperature resistance (such as aerogel boards), multi-layer vacuum insulation boards, or refractory ceramic fiber insulation materials. These materials possess excellent chemical stability and are not easily decomposed, sintered, or deteriorated under high-temperature environments (e.g., 600-1000℃). To achieve long-term, efficient heat preservation, their thickness is typically tens of centimeters to over half a meter. Through the design of the insulation layer, the internal temperature of the reaction vessel is controlled to remain at least 150 degrees Celsius below normal when not in operation, and the heat preservation time can reach over 24 hours. The corrosion-resistant layer 1402C is located on the innermost side of the outer shell of the reaction vessel, directly contacting the internal high-temperature reaction medium (water vapor, carbon dioxide, hydrogen, carbon monoxide, and a small amount of oxygen). This layer material possesses excellent corrosion resistance to high-temperature gases. Special high-temperature alloys or high-temperature ceramic coatings are selected. This layer possesses good density, anti-peeling properties, and long-term high-temperature stability. Through the above three-layer structure, the high-temperature co-electrolysis device can be provided with good mechanical strength, efficient heat preservation, and excellent corrosion resistance, ensuring long-term stable operation of the device in harsh marine environments.

[0046] Furthermore, in this preferred embodiment, the anode 1404 and cathode 1407 of the reaction vessel 140 are made of materials that are resistant to high temperatures and corrosion and have excellent electrocatalytic activity, such as a nickel / yttrium oxide-stabilized zirconium oxide composite material as the cathode, and lanthanum strontium cobalt iron oxide or lanthanum strontium manganese oxide as the anode. An electrochemical reaction zone is formed between the anode 1404 and the cathode 1407, where water vapor and CO2 undergo a co-electrolysis reaction driven by electrical energy, thereby efficiently generating syngas. The reaction vessel is provided with an anode inlet 1401 and an anode outlet 1403 for circulating the anode gas (such as oxygen or air). The cathode inlet 1410 and the cathode outlet 1408 are used for the entry of raw material gases (water vapor and CO2) and the discharge of reaction products (syngas). A drying device 1409 is provided before the cathode outlet 1408 to remove moisture from the gaseous products to obtain syngas with higher purity. Furthermore, the heating rod circuit 1405 installed within the reaction vessel cavity provides and maintains the high-temperature environment required for the reaction. The temperature / pressure monitor 1411 monitors the internal temperature and pressure of the device in real time, ensuring the reaction proceeds under preset process parameters. The pressure relief valve 1406 is used to regulate the internal pressure of the device in real time to maintain pressure balance and safe operation. The permeation membrane 1412 can be used for gas separation, promoting the permeation of specific components (oxygen ions) to optimize product purity or improve reaction efficiency. Through the built-in heating rod circuit, temperature / pressure sensor, pressure relief valve, and other devices, the reaction device can be maintained at optimal operating temperature and pressure, reducing energy consumption and improving syngas production efficiency.

[0047] Preferably, the system includes an intelligent control module for intelligently scheduling the number of containers operating in the high-temperature co-electrolysis reactor and the load of each container based on real-time data collected from the offshore wind turbine, carbon capture device, pretreatment boiler, and high-temperature co-electrolysis reactor.

[0048] Figure 4 This is a schematic diagram of a high-temperature co-electrolysis apparatus comprising multiple high-temperature co-electrolysis reaction vessels according to a preferred embodiment of the present invention. The high-temperature co-electrolysis apparatus of the present invention may comprise multiple high-temperature co-electrolysis vessels, such as... Figure 4As shown, the high-temperature co-electrolysis device of this preferred embodiment consists of an array of three independent reaction vessels. In this array, electrical energy from the offshore wind turbine generator 101 is connected via cables to the anode 1404 and cathode 1407 of each vessel. Raw material steam and CO2 are connected to the cathode inlet 510 of each vessel via independent branch pipes, while syngas is discharged from the cathode outlet 1408 via independent branch pipes and merged into the main pipeline. Because the electrical connection of the reaction window array allows for individual start-stop control of each reaction vessel, the intelligent control module collects key operating data such as temperature, pressure, flow rate, current, voltage, and gas composition in real time through sensors distributed throughout the components. Based on wind power prediction and implementation data, it can intelligently schedule the number of operating vessels and the load of each vessel to achieve intelligent power absorption. This modular design allows the system to flexibly adjust the number of operating vessels according to the real-time power generation of the offshore wind turbine generator, enabling the activation of more vessels when power generation is high and fewer vessels when power generation is low. For devices that are not in operation, their high-efficiency insulation layer can effectively maintain the internal temperature within a suitable range, and can be quickly restarted when the power is appropriate. If the continuous power is low, a rotating operation mode can also be adopted to keep each device within a suitable temperature range, ensuring the instantaneous response capability and equipment life of the entire array.

[0049] Preferably, the system further includes a mixing and pressurizing device connected to the carbon capture device and the pretreatment boiler, for transmitting carbon dioxide and water vapor, which are mixed and pressurized according to a custom ratio, to the high-temperature co-electrolysis reactor.

[0050] In this preferred embodiment, the mixing and pressurizing device is an air pump, and the carbon capture device is connected to the air pump via a gas delivery pipeline, inputting carbon dioxide, one of the raw materials for generating syngas, into the cathode feed port of the high-temperature co-electrolysis reactor. The pretreatment boiler is connected to the air pump via a steam delivery pipeline, inputting steam, one of the raw materials for generating syngas, into the cathode feed port of the high-temperature co-electrolysis reactor.

[0051] Preferably, the system further includes a compression device connected to the high-temperature co-electrolysis reactor for compressing the syngas to a high-pressure state suitable for storage and transportation.

[0052] In this preferred embodiment, the compression device is a compressor. The compressor is connected to the cathode outlet of the high-temperature co-electrolysis reactor and is used to compress the syngas generated by the reaction to a state suitable for storage and transportation.

[0053] Furthermore, the compressor can also be connected to a tubular container, which is a standardized modular storage unit used for the safe and efficient storage of compressed syngas. The tubular container can be designed to comply with international transport standards, facilitating subsequent loading, unloading, and multimodal transport.

[0054] The system for producing syngas by coupling offshore wind power with high-temperature co-electrolysis, as described in this preferred embodiment, introduces high-temperature co-electrolysis technology into existing offshore wind power systems to produce storable and transportable syngas. Utilizing the high-temperature co-electrolysis device's excellent adaptability to power fluctuations and its intelligent control system, the system can select operating modes and power outputs based on real-time grid prices and grid dispatch instructions, achieving peak-shifting energy supply and absorption. This opens up new application areas for large-scale storage and utilization of renewable energy and provides innovative solutions for addressing energy absorption from offshore wind power and reducing wind curtailment rates. Furthermore, the reaction vessel shell in the high-temperature co-electrolysis reactor of this invention adopts a three-layer composite structure, especially the insulation layer design, which allows the reactor to maintain a suitable operating temperature for extended periods when wind power fluctuates or is insufficient. This significantly reduces preheating energy consumption and time during frequent start-ups and shutdowns, improving the system's response speed and overall operating efficiency.
