Description

Technical Field

[0001] This invention relates to the field of green hydrogen energy storage technology, and more specifically, to a green hydrogen energy storage device, control method, control device, and readable storage medium. Background Technology

[0002] In related technologies, with the widespread application of distributed wind power, photovoltaics, and other renewable energy sources, the intermittency and instability of their output restrict reliable power supply in off-grid or weakly gridded areas. Consequently, green hydrogen energy storage has been chosen as an energy storage option. However, while green hydrogen energy storage has advantages such as high energy density and long-cycle storage, to meet energy demands, green hydrogen energy storage systems are often large in size and have low integration, making it difficult to achieve mobile and miniaturized deployment. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] Therefore, the first aspect of the present invention provides a green hydrogen energy storage device.

[0005] A second aspect of the present invention provides a control method for a green hydrogen energy storage device.

[0006] A third aspect of the present invention provides a control device for a green hydrogen energy storage device.

[0007] A fourth aspect of the present invention provides another control device for a green hydrogen energy storage device.

[0008] The fifth aspect of this application proposes a readable storage medium.

[0009] In view of the above, the first aspect of this application provides a green hydrogen energy storage device comprising: a container, a hydrogen storage module, a hydrogen production module, a hydrogen power generation module, and a control device. The hydrogen storage module is installed inside the container and includes a hydrogen storage container and a container liner, with the container liner disposed inside the hydrogen storage container. The hydrogen production module is installed inside the container, with its output end connected to the input end of the hydrogen storage module, and the hydrogen produced by the hydrogen production module can be transported to the container liner for storage. The hydrogen power generation module is installed inside the container, with its input end connected to the output end of the hydrogen storage module. The control device is installed inside the container and is communicatively connected to the hydrogen production module, the hydrogen storage module, and the hydrogen power generation module, respectively, and is used to control the operation of the hydrogen production module, the hydrogen storage module, and the hydrogen power generation module.

[0010] This application provides a green hydrogen energy storage device that achieves system compactness and ease of mobility through an integrated container design, adapting to diverse deployment scenarios. Specifically, this application integrates hydrogen storage components, hydrogen production components, hydrogen power generation components, and control devices within a single container, creating a compact and well-organized integrated system. The container, as a standardized carrier, provides a unified installation and protection foundation for each functional component, avoiding the problems of large space occupation, messy connecting pipelines, and high integration difficulty caused by the dispersed deployment of components in traditional green hydrogen energy storage systems. Furthermore, its standardized size design adapts to various transportation methods, including land and sea transport, enabling rapid deployment to remote mountainous areas, islands, emergency rescue sites, and base stations—areas difficult to reach with traditional power supply facilities. Secondly, the container's airtightness and structural strength provide excellent protection for the internal hydrogen-related components and electrical equipment, resisting the impact of the external environment on equipment operation and improving system reliability in complex environments. Simultaneously, the centralized layout significantly shortens the connecting pipelines between the hydrogen production and storage components, and between the hydrogen storage and power generation components, reducing the risk of leakage and pressure loss during hydrogen transportation, thus improving system safety and reducing energy consumption.

[0011] The hydrogen storage assembly employs a composite structure design of a hydrogen storage container and an inner liner. The storage container, as the core carrier for hydrogen storage, provides structural support for high-pressure storage. The inner liner is fitted tightly to the inner wall of the storage container, forming a synergistic storage system between the carrier and the functional layer. The presence of the liner enhances hydrogen storage capacity through adsorption, chemical reactions, and other processes, increasing the amount of hydrogen stored per unit volume. For example, the adsorption properties of the liner material allow the hydrogen storage container to achieve a hydrogen storage density increase of over 30% at operating pressures of 30 MPa to 37 MPa, thereby enabling the storage of more hydrogen to meet multi-day energy storage and continuous power supply requirements.

[0012] In one technical solution of this application, the container includes an isolation structure that isolates at least two functional zones inside the container. The hydrogen storage component and the hydrogen production component are located in the first zone of the at least two functional zones; the hydrogen power generation component and the control device are located in the other functional zones of the at least two functional zones besides the first zone.

[0013] In this technical solution, the container is divided into at least two functional zones using an isolation structure. Hydrogen storage and production components are centrally located in the first zone, while hydrogen power generation components and control devices are located in other zones, achieving both safety isolation and functional clustering. Hydrogen storage and production components are core hydrogen-related components, facing safety risks such as hydrogen leakage and pressure fluctuations during operation. Hydrogen power generation components and control devices have even higher requirements for environmental safety and stability. The isolation structure forms a physical barrier, effectively preventing hydrogen leakage from spreading to the electrical and power generation areas, avoiding safety hazards caused by hydrogen contact with high-temperature components, and preventing vibrations and heat generated by the power generation components from affecting the precision control performance of the control devices. From a layout optimization perspective, functional zoning allows for the centralized arrangement of similar functional components, more concentrated connections for hydrogen storage and production pipelines, and a more organized cable layout for hydrogen power generation and control devices. This reduces interference between different functional systems and facilitates targeted maintenance by operation and maintenance personnel. For example, when maintaining the first hydrogen-related zone, other functional zones can be maintained without shutting down, or the control devices can be debugged separately, improving operation and maintenance efficiency and system availability. This allows the multi-system layout within the compact container to meet safety standards while also taking into account the practicality of operation and maintenance, adapting to complex scenarios where high-pressure hydrogen-related processes and precision control coexist.

[0014] In one technical solution of this application, the first partition includes two sub-partitions, and the hydrogen storage component and the hydrogen production component are respectively disposed in the two sub-partitions.

[0015] In this technical solution, the first zone is further divided into two sub-zones, with the hydrogen storage and hydrogen production components arranged independently. This further enhances the safety and operational efficiency of the hydrogen-related areas. The core of the hydrogen storage component is the high-pressure hydrogen storage container (operating pressure 30MPa-37MPa), which requires stable pressure and a collision-resistant installation location. The hydrogen production components consist of an electrolysis hydrogen production device and a gas compression device, designed to maintain stable power and facilitate heat dissipation. Therefore, their operating characteristics and safety concerns differ. The independent sub-zones are further separated by an isolation structure, preventing vibrations generated by the hydrogen production component from being directly transmitted to the high-pressure hydrogen storage container, reducing sealing losses or pressure fluctuations in the container body due to vibration. Simultaneously, the small amount of condensate and heat that may be generated during hydrogen production will not directly affect the storage environment of the hydrogen storage component, ensuring the dryness and stability of the stored hydrogen. In addition, the sub-zone design enables graded isolation of hydrogen-related risks. Even if a small amount of hydrogen leaks in one sub-zone, the isolation structure of another sub-zone can delay the spread of the leak and reserve response time for safety protection systems (such as ventilation and alarms). This further enhances the safety redundancy of the system in the core hydrogen-related area and also facilitates the individual inspection and maintenance of hydrogen storage or hydrogen production components without affecting the temporary operation of other components.

[0016] In one technical solution of this application, the hydrogen production assembly includes an electrolytic hydrogen production device and a gas compression device. The electrolytic hydrogen production device is communicatively connected to a control device. The input end of the gas compression device is connected to the electrolytic hydrogen production device, and the output end is connected to a hydrogen storage container. The gas compression device is also communicatively connected to the control device. The control device controls the operation of the electrolytic hydrogen production device and the gas compression device through control commands.

[0017] In this technical solution, the hydrogen production component includes an electrolytic hydrogen production unit and a gas compression unit, both of which are connected to the control device, constructing a closed-loop adaptive link for hydrogen production, compression, and storage, achieving the technical effects of efficient hydrogen production and stable hydrogen transportation. The electrolytic hydrogen production unit, as the core of hydrogen production, has wide power fluctuation adaptability and can directly absorb fluctuating power from renewable energy sources such as wind and solar, converting electrical energy into hydrogen. The gas compression unit specifically addresses the adaptation problem from low-pressure hydrogen to high-pressure hydrogen storage. Because the hydrogen produced by the electrolytic hydrogen production unit has a low pressure, it cannot be directly stored in high-pressure hydrogen storage containers of 30MPa-37MPa. The gas compression unit, through staged compression, increases the hydrogen pressure to a range matching the hydrogen storage container, ensuring stable hydrogen storage and avoiding low storage efficiency or leakage risks due to pressure mismatch. The control unit adjusts the hydrogen production rate of the electrolytic hydrogen production unit based on real-time pressure data from the hydrogen storage components, while simultaneously adjusting the compression power of the gas compression unit. This ensures that the hydrogen production and compression delivery are matched, preventing pipeline congestion due to excessively rapid hydrogen production and avoiding impacting hydrogen production efficiency due to excessively slow compression. When wind and solar power fluctuate, the control unit can first adjust the operating power of the electrolytic hydrogen production unit, and then coordinate with the gas compression unit to adapt to the new hydrogen production, ensuring the stability and efficiency of the entire hydrogen production and storage chain.

[0018] In one technical solution of this application, the green hydrogen energy storage device also includes an auxiliary support component, which is communicatively connected to the control device. The auxiliary support component includes a coolant pump, which is used to provide circulating cooling for the electrolytic hydrogen production device and the hydrogen power generation component.

[0019] In this technical solution, a coolant pump in the auxiliary support component provides circulating cooling for the electrolytic hydrogen production unit and the hydrogen power generation unit, achieving the technical effects of temperature control, equipment protection, and efficiency maintenance. During operation of the electrolytic hydrogen production unit, the current passing through the electrolyte generates heat, and the temperature must be maintained within the optimal range of 25℃-60℃ to ensure electrolysis efficiency and membrane module lifespan. During operation of the hydrogen power generation unit (hydrogen gas turbine), the combustion chamber and turbine components generate high temperatures, with exhaust temperatures reaching 0K-5K, requiring timely heat dissipation to prevent overheating and damage. The coolant pump drives the circulating flow of cooling medium, precisely removing excess heat generated by the two core components, ensuring the temperature of the electrolytic hydrogen production unit remains stable within the high-efficiency range, and the temperature of the hydrogen gas turbine components is controlled within safe thresholds, preventing equipment failure or performance degradation due to high temperatures.

[0020] When the hydrogen electrolysis unit operates at full load, the coolant pump adapts to changes in heat generation through frequency conversion adjustment, preventing temperature fluctuations from affecting electrolysis efficiency. During the start-up and shutdown of the hydrogen gas turbine, the coolant pump starts early or shuts down late, achieving full-cycle temperature control from preheating to operation to cooling, thus extending the equipment's service life. This targeted cooling design provides a fundamental guarantee for the continuous and stable operation of the two core components of hydrogen production and power generation, indirectly ensuring the energy cycle efficiency of the entire green hydrogen energy storage device.

[0021] A second aspect of the present invention provides a control method for a green hydrogen energy storage device, used in the green hydrogen energy storage device described above. The green hydrogen energy storage device further includes an energy access module. The control method for the green hydrogen energy storage device includes: acquiring pressure parameters of the hydrogen storage component, operating power parameters of the hydrogen production component, load demand parameters of the hydrogen power generation component, and energy supply status parameters; adjusting the operating power of the hydrogen production component or the hydrogen input rate of the hydrogen power generation component according to the pressure parameters and energy supply status parameters through a control device; monitoring the safety status parameters of the hydrogen storage component, and triggering a safety protection action when the safety status parameters reach a set threshold.

[0022] This application provides a control method for a green hydrogen energy storage device, used in the green hydrogen energy storage device described above. The green hydrogen energy storage device also includes an energy access module. The control method includes acquiring pressure parameters of the hydrogen storage component, operating power parameters of the hydrogen production component, load demand parameters of the hydrogen power generation component, and energy supply status parameters; adjusting the operating power of the hydrogen production component or the hydrogen input rate of the hydrogen power generation component based on the pressure parameters and energy supply status parameters using a control device; monitoring the safety status parameters of the hydrogen storage component, and triggering a safety protection action when the safety status parameters reach a set threshold. The control method for the green hydrogen energy storage device proposed in this application comprehensively acquires key parameters such as the pressure of the hydrogen storage module, the operating power of the hydrogen production module, the load demand of the hydrogen power generation module, and the energy supply status. This provides the control device with precise decision-making basis, enabling it to dynamically adjust the operating power of the hydrogen production module or the hydrogen input rate of the hydrogen power generation module based on real-time operating conditions. This achieves precise matching between energy supply and hydrogen storage status, efficiently absorbing renewable energy and avoiding problems such as hydrogen overpressure or insufficient power supply. Furthermore, by monitoring the safety status parameters of the hydrogen storage module in real time and triggering safety protection actions when the set threshold is reached, a closed-loop control logic of "data acquisition - dynamic regulation - safety protection" is constructed. This ensures that the device operates intelligently, efficiently, and safely under multiple operating conditions, perfectly adapting to diverse application scenarios such as wind and solar power integration, grid support, and islanded operation.

[0023] In one technical solution of this application, adjusting the operating power of the hydrogen production component or the hydrogen input rate of the hydrogen power generation component by means of a control device based on pressure parameters and energy supply status parameters includes: when the pressure parameter is higher than a first preset pressure value, the control device sends a power reduction command to the hydrogen production component or sends a start command to the hydrogen power generation component; when the pressure parameter is lower than the first preset pressure value, the control device sends a power reduction command to the hydrogen power generation component or sends a supplementary power hydrogen production command to the energy access module to switch to backup power supply for hydrogen production; when the output power of the wind power and photovoltaic generator is lower than the minimum load threshold of the electrolysis hydrogen production device, the control device controls the energy access module to switch to grid or backup power supply to maintain the operation of the hydrogen production component.

[0024] In this technical solution, the control logic of this application achieves dynamic balance of hydrogen storage system pressure by precisely regulating hydrogen storage pressure and energy supply status in different scenarios. When the pressure is higher than the first preset pressure value, the hydrogen production power is reduced or power generation is started to consume hydrogen to avoid the risk of hydrogen overpressure. When the pressure is lower than the first preset pressure value, the hydrogen consumption is reduced by reducing power generation output or supplementing hydrogen reserves by generating electricity, ensuring that the hydrogen storage status is always in a safe and efficient range. It can also adapt to the fluctuation of energy supply. When the wind and solar output power is lower than the minimum load threshold of the electrolysis hydrogen production device, the operation of the hydrogen production components is maintained by switching the grid or backup power supply, avoiding efficiency decay or equipment damage caused by low load operation of the hydrogen production device. At the same time, it ensures that the hydrogen production process is uninterrupted, realizing the synergy of efficient consumption of renewable energy and flexible supplementation of external energy, further enhancing the stability, safety and continuity of energy utilization of the system operation, and enabling the green hydrogen energy storage device to operate reliably under complex and ever-changing energy supply and load demand conditions.

[0025] A third aspect of the present invention provides a control device for a green hydrogen energy storage device, and a control method for executing the green hydrogen energy storage device described above. The control device for the green hydrogen energy storage device includes: a first control module, a second control module, and a third control module. The first control module is used to acquire pressure parameters of the hydrogen storage component, operating power parameters of the hydrogen production component, load demand parameters of the hydrogen power generation component, and energy supply status parameters. The second control module is used to adjust the operating power of the hydrogen production component or the hydrogen input rate of the hydrogen power generation component according to the pressure parameters and energy supply status parameters through the control device. The third control module is used to monitor the safety status parameters of the hydrogen storage component, and trigger a safety protection action when the safety status parameters reach a set threshold.

[0026] This application provides a control device for a green hydrogen energy storage device, which is used to implement the control method of the green hydrogen energy storage device described above. The control device includes a first control module, a second control module, and a third control module. The first control module is used to acquire the pressure parameters of the hydrogen storage component, the operating power parameters of the hydrogen production component, the load demand parameters of the hydrogen power generation component, and the energy supply status parameters. The second control module is used to adjust the operating power of the hydrogen production component or the hydrogen input rate of the hydrogen power generation component according to the pressure parameters and energy supply status parameters. The third control module is used to monitor the safety status parameters of the hydrogen storage component. When the safety status parameters reach a set threshold, a safety protection action is triggered. This achieves a closed-loop coordination of accurate parameter acquisition, dynamic operation control, and timely safety protection. It provides comprehensive and reliable data support for control decisions, can quickly adapt to changes in operating conditions to optimize system operating efficiency, and accurately prevents and controls safety risks, ensuring the intelligent, efficient, and stable operation of the green hydrogen energy storage device.

[0027] A fourth aspect of the present invention provides a control device for a green hydrogen energy storage device, comprising: a processor and a memory, wherein the memory stores a program or instructions, and the processor, when executing the program or instructions in the memory, implements the steps of the control method for the green hydrogen energy storage device as described in the above-described technical solution. Therefore, the control device for the green hydrogen energy storage device possesses all the beneficial effects of the control method for the green hydrogen energy storage device as described in the above-described technical solution.

Detailed Implementation

[0048] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0049] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0050] The following reference Figures 1 to 15 This invention describes a green hydrogen energy storage device, control method, control device, and readable storage medium according to some embodiments of the present invention.

[0051] like Figure 1 and Figure 2 As shown, an embodiment of this application provides a green hydrogen energy storage device 100, including: a container 110, a hydrogen storage module 130, a hydrogen production module 120, a hydrogen power generation module 150, and a control device 160. The hydrogen storage module 130 is installed inside the container 110 and includes a hydrogen storage container 132 and a container liner 134, with the container liner 134 disposed inside the hydrogen storage container 132. The hydrogen production module 120 is installed inside the container 110, and the output end of the hydrogen production module 120 is connected to the input end of the hydrogen storage module 130. The hydrogen produced by the hydrogen production assembly 120 can be transported to the inner liner 134 of the container for storage; the hydrogen power generation assembly 150 is installed inside the container 110, and the input end of the hydrogen power generation assembly 150 is connected to the output end of the hydrogen storage assembly 130; the control device 160 is installed inside the container 110, and the control device 160 is communicatively connected to the hydrogen production assembly 120, the hydrogen storage assembly 130 and the hydrogen power generation assembly 150 respectively, and the control device 160 is used to control the operation of the hydrogen production assembly 120, the hydrogen storage assembly 130 and the hydrogen power generation assembly 150.

[0052] This application provides a green hydrogen energy storage device 100, which achieves system compactness and ease of mobility through an integrated design using a container 110, adapting to diverse deployment scenarios. Specifically, this application integrates the hydrogen storage component 130, hydrogen production component 120, hydrogen power generation component 150, and control device 160 within the container 110, constructing a compact and well-organized integrated equipment. The container 110, as a standardized carrier, provides a unified installation and protection foundation for each functional component, avoiding the problems of large space occupation, messy connecting pipelines, and high integration difficulty caused by the dispersed deployment of components in traditional green hydrogen energy storage systems. Furthermore, its standardized size design adapts to various transportation methods such as land and sea, enabling rapid deployment to remote mountainous areas, islands, emergency rescue sites, base stations, and other areas difficult to cover by traditional power supply facilities. Secondly, the container 110's airtightness and structural strength provide excellent protection for the internal hydrogen-related components and electrical equipment, resisting the impact of the external environment on equipment operation and improving the system's reliability in complex environments. Meanwhile, the centralized layout significantly shortens the connecting pipelines between the hydrogen production module 120 and the hydrogen storage module 130, and between the hydrogen storage module 130 and the hydrogen power generation module 150, reducing the risk of leakage and pressure loss during hydrogen transportation, thereby improving system safety and reducing energy consumption.

[0053] The hydrogen storage assembly 130 adopts a composite structure design of a hydrogen storage container 132 and a container liner 134. The hydrogen storage container 132 serves as the core carrier for hydrogen storage, providing structural support for high-pressure storage. The container liner 134 is fitted into the inner wall of the hydrogen storage container 132, forming a synergistic storage system between the carrier and the functional layer. The presence of the liner can enhance the hydrogen storage capacity through adsorption, adsorption, and chemical reactions, increasing the amount of hydrogen stored per unit volume. For example, through the adsorption characteristics of the liner material, the hydrogen storage density of the hydrogen storage container 132 can be increased by more than 30% under operating pressures of 30 MPa to 37 MPa, thereby enabling the storage of more hydrogen to meet the needs of multi-day energy storage and continuous power supply.

[0054] Meanwhile, the inner liner 134 also serves to buffer pressure fluctuations and protect the main body of the hydrogen storage container 132. Specifically, when the hydrogen production assembly 120 continuously produces hydrogen, causing the pressure inside the tank to rise, the inner liner can slow down the rate of pressure increase by adsorbing hydrogen, preventing a sudden pressure surge from impacting the container. When the hydrogen power generation assembly 150 consumes hydrogen, causing the pressure to drop, the hydrogen adsorbed by the inner liner can be gradually desorbed and released, maintaining stable pressure inside the tank and reducing the impact of pressure fluctuations on storage safety. This approach balances the high efficiency of high-pressure hydrogen storage with enhanced safety and stability during storage through the functional enhancement of the inner liner, enabling high-density hydrogen storage within a limited space.

[0055] This application specifies that the output of the hydrogen production module 120 is connected to the input of the hydrogen storage module 130, and the output of the hydrogen storage module 130 is connected to the input of the hydrogen power generation module 150, forming a closed-loop energy flow chain of green electricity hydrogen production, hydrogen storage, and hydrogen power generation. When wind and solar resources are abundant, the hydrogen production module 120 operates at full capacity, converting excess electricity into hydrogen energy for storage, thus avoiding energy waste. When wind and solar resources are scarce or load demand surges, the hydrogen power generation module 150 starts up quickly, converting the stored hydrogen energy into stable electricity to fill the energy supply gap.

[0056] The control device 160 establishes communication connections with the hydrogen production module 120, the hydrogen storage module 130, and the hydrogen power generation module 150, respectively, and assumes the role of central control in the system. Through the communication connection, the control device 160 can obtain the operating power of the hydrogen production module 120, the pressure and storage status of the hydrogen storage module 130, and the load demand and operating parameters of the hydrogen power generation module 150 in real time. Based on this real-time data, it makes global optimization decisions and sends precise control commands to each module to achieve dynamic matching of the operating status of each link.

[0057] For example, when the control device 160 detects high pressure in the hydrogen storage component 130, it can autonomously adjust the hydrogen production rate of the hydrogen component 120 or start the hydrogen power generation component 150 in advance to consume hydrogen, thus preventing overpressure in the hydrogen storage container 132. When an increase in load demand is detected, the control device 160 can quickly adjust the hydrogen input rate of the hydrogen power generation component 150 to increase power generation and ensure stable output power. When the operating status of the hydrogen production component 120 changes due to fluctuations in wind and solar power, the control device 160 can synchronously adjust the operating parameters of the gas compression device 124 to ensure the stability of hydrogen delivery.

[0058] The control device 160, with its communication connection and centralized control functions, establishes data interaction with each component via wired or wireless communication. It collects key parameters in real time, such as the input power and electrolysis efficiency of the hydrogen production component 120, the pressure and temperature of the hydrogen storage component 130, and the output power and exhaust temperature of the hydrogen power generation component 150, and makes decisions based on preset algorithms. For example, when the output power of wind and solar power suddenly changes, the control device 160 can adjust the electrolysis current of the hydrogen production component 120 to smooth power fluctuations and prevent damage to the electrolyzer stack. When the hydrogen storage pressure reaches 37 MPa, the control device 160 automatically sends a power reduction command to the hydrogen production component 120 or starts the hydrogen power generation component 150 to consume hydrogen, ensuring that the system pressure remains stable within a safe range.

[0059] In one embodiment of this application, the container 110 includes an isolation structure 114, which isolates at least two functional partitions 112 inside the container 110. The hydrogen storage component 130 and the hydrogen production component 120 are disposed in the first partition 113 of the at least two functional partitions 112. The hydrogen power generation component and the control device 160 are disposed in the other functional partitions 112 besides the first partition 113 of the at least two functional partitions 112.

[0060] In this embodiment, the container 110 is divided into at least two functional zones 112 by an isolation structure 114. The hydrogen storage component 130 and the hydrogen production component 120 are centrally arranged in the first zone 113, while the hydrogen power generation component 150 and the control device 160 are arranged in other zones, achieving the technical effects of safe isolation and functional clustering. The hydrogen storage component 130 and the hydrogen production component 120 are core hydrogen-related components, and there are safety risks such as hydrogen leakage and pressure fluctuations during operation. The hydrogen power generation component 150 and the control device 160 have higher requirements for environmental safety and stability. The isolation structure 114 forms a physical barrier, which can effectively prevent the diffusion of hydrogen leakage to the electrical area and the power generation area, avoid the safety hazards caused by hydrogen contact with high-temperature components, and prevent the vibration and heat generated by the operation of the power generation component from affecting the precision control performance of the control device 160. From a layout optimization perspective, functional zone 112 allows for the centralized arrangement of similar functional components, more concentrated connections for hydrogen storage and production pipelines, and a more organized cable layout for the hydrogen power generation and control device 160. This reduces interference between different functional systems and facilitates targeted maintenance by operation and maintenance personnel. For example, when maintaining the hydrogen-related first zone 113, other functional zones 112 can be maintained without shutting down, or the control device 160 can be debugged separately, improving operation and maintenance efficiency and system availability. Consequently, the multi-system layout within the compact container 110 meets safety regulations while also considering the practicality of operation and maintenance, adapting to complex scenarios where high-pressure hydrogen-related processes and precision control coexist.

[0061] In one embodiment of this application, the first partition 113 includes two sub-partitions, and the hydrogen storage component 130 and the hydrogen production component 120 are respectively disposed in the two sub-partitions.

[0062] In this embodiment, the first partition 113 is further divided into two sub-partitions, with the hydrogen storage assembly 130 and the hydrogen production assembly 120 arranged independently. This further enhances the safety protection and operational efficiency of the hydrogen-related area. The core of the hydrogen storage assembly 130 is the high-pressure hydrogen storage container 132 (operating pressure 30MPa-37MPa), which requires stable pressure and a collision-resistant installation position. The hydrogen production assembly 120 consists of the electrolysis hydrogen production device 122 and the gas compression device 124. The design requirements are to maintain stable power and facilitate heat dissipation, so their operating characteristics and safety concerns are different. The independent sub-partitions are further separated by the isolation structure 114, which prevents the vibration generated by the operation of the hydrogen production assembly 120 from being directly transmitted to the high-pressure hydrogen storage container 132, reducing sealing losses or pressure fluctuations in the container body caused by vibration. At the same time, the small amount of condensate and heat that may be generated during hydrogen production will not directly affect the storage environment of the hydrogen storage assembly 130, ensuring the dryness and stability of hydrogen storage. In addition, the sub-zone design enables graded isolation of hydrogen-related risks. Even if a small amount of hydrogen leaks in one sub-zone, the isolation structure 114 of another sub-zone can delay the expansion of the leak range, reserve response time for safety protection systems (such as ventilation and alarms), further enhance the safety redundancy of the system in the core hydrogen-related area, and also facilitate the separate inspection and maintenance of hydrogen storage or hydrogen production components 120 without affecting the temporary operation of other components.

[0063] In one embodiment of this application, the hydrogen power generation component 150 includes a 10kW-class hydrogen gas turbine.

[0064] In this embodiment, the hydrogen power generation component 150 employs a 10kW-class hydrogen gas turbine, achieving the technical effects of power adaptation, rapid response, and low-noise operation. From a power adaptation perspective, the 10kW-class output power is highly compatible with the needs of distributed loads (such as remote base stations, emergency rescue, and small microgrids), directly providing stable power to the load without the need for additional power conversion equipment, thus reducing energy loss. Simultaneously, the power level matches the production capacity and hydrogen storage capacity of the hydrogen production component 120 (proton exchange membrane electrolyzer) and the hydrogen storage component 130 (100L high-pressure vessel). That is, the hydrogen stored in the hydrogen storage component 130 can support the gas turbine's continuous operation for more than 5 hours, meeting multi-day emergency power supply or off-grid power supply needs. From an operational perspective, the hydrogen gas turbine possesses rapid start-up and shutdown characteristics and rapid load response, with a start-up response time of less than 5 seconds. It can quickly start consuming hydrogen when the hydrogen storage pressure is abnormal, or rapidly adjust the power generation capacity to fill energy supply gaps when load demand changes abruptly.

[0065] In one embodiment of this application, the hydrogen production assembly includes an electrolytic hydrogen production device 122 and a gas compression device 124. The electrolytic hydrogen production device 122 is communicatively connected to a control device 160. The input end of the gas compression device 124 is connected to the electrolytic hydrogen production device 122, and the output end is connected to a hydrogen storage container 132. The gas compression device 124 is also communicatively connected to the control device 160. The control device 160 controls the operation of the electrolytic hydrogen production device 122 and the gas compression device 124 through control commands.

[0066] In this embodiment, the hydrogen production assembly 120 includes an electrolytic hydrogen production device 122 and a gas compression device 124, both of which are connected to the control device 160, forming a closed-loop adaptation link for hydrogen production, compression, and storage, achieving the technical effects of efficient hydrogen production and stable hydrogen transportation. The electrolytic hydrogen production device 122, as the core of hydrogen production, has wide power fluctuation adaptability and can directly absorb fluctuating power from renewable energy sources such as wind and solar, converting electrical energy into hydrogen. The gas compression device 124 specifically addresses the adaptation problem from low-pressure hydrogen to high-pressure hydrogen storage. Because the hydrogen pressure generated by the electrolytic hydrogen production device 122 is relatively low, it cannot be directly stored in the 30MPa-37MPa high-pressure hydrogen storage container 132. The gas compression device 124, through staged compression, increases the hydrogen pressure to a range matching the hydrogen storage container 132, ensuring stable hydrogen storage and avoiding low storage efficiency or leakage risks due to pressure mismatch. Based on the real-time pressure data of the hydrogen storage component 130, the control device 160 adjusts the hydrogen production rate of the electrolytic hydrogen production unit 122, and simultaneously adjusts the compression power of the gas compression unit 124 to ensure that the hydrogen production and compression delivery are matched. This prevents pipeline congestion due to excessively rapid hydrogen production, and avoids affecting hydrogen production efficiency due to excessively slow compression. When wind and solar power fluctuate, the control device 160 can first adjust the operating power of the electrolytic hydrogen production unit 122, and then coordinate with the gas compression unit 124 to adapt to the new hydrogen production, ensuring the stability and efficiency of the entire hydrogen production and storage chain.

[0067] In one embodiment of this application, the green hydrogen energy storage device 100 further includes an auxiliary support component 140, which is communicatively connected to the control device 160. The auxiliary support component 140 includes a coolant pump 170, which is used to provide circulating cooling for the electrolytic hydrogen production device 122 and the hydrogen power generation component 150.

[0068] In this embodiment, the coolant pump 170 in the auxiliary support component 140 provides circulating cooling for the electrolytic hydrogen production unit 122 and the hydrogen power generation component 150, achieving the technical effects of temperature control, equipment protection, and efficiency maintenance. When the electrolytic hydrogen production unit 122 is running, the current passing through the electrolyte generates heat, and the temperature needs to be maintained within the optimal range of 25℃-60℃ to ensure electrolysis efficiency and membrane module lifespan. When the hydrogen power generation component 150 (hydrogen gas turbine) is running, the combustion chamber and turbine components generate high temperatures, with exhaust temperatures reaching 1040K-1135K, requiring timely heat dissipation to prevent overheating and damage. The coolant pump 170 drives the circulating flow of the cooling medium, precisely removing excess heat generated by the two core components, ensuring that the temperature of the electrolytic hydrogen production unit 122 remains stable within the high-efficiency range, and that the temperature of the hydrogen gas turbine components is controlled within safe thresholds, preventing equipment failure or performance degradation due to high temperatures.

[0069] When the electrolysis hydrogen production unit 122 is running at full load, the coolant pump 170 adapts to changes in heat generation through frequency conversion adjustment, preventing temperature fluctuations from affecting electrolysis efficiency. During the start-up and shutdown of the hydrogen gas turbine, the coolant pump 170 starts early or shuts down late, achieving full-cycle temperature control from preheating to operation to cooling, thus extending the equipment's service life. This targeted cooling design provides a fundamental guarantee for the continuous and stable operation of the two core components of hydrogen production and power generation, indirectly ensuring the energy cycle efficiency of the entire green hydrogen energy storage device 100.

[0070] In one embodiment, the green hydrogen energy storage device 100 of this application further includes a hydrogen storage component 130 that includes a pressure monitoring unit and a multi-stage safety valve 148. The pressure monitoring unit is communicatively connected to a control device 160, and the multi-stage safety valve 148 is installed at key nodes of the hydrogen storage container 132 and the hydrogen delivery pipeline. The device monitors the hydrogen storage pressure in real time and feeds it back to the control device 160. The multi-stage safety valve 148 releases pressure in stages at key nodes of the container and pipeline, avoiding overpressure risks and comprehensively ensuring the safety and stability of the high-pressure hydrogen storage process.

[0071] The green hydrogen energy storage device 100 also includes an auxiliary protection component 140, which is communicatively connected to the control device 160. The auxiliary protection component 140 includes a ventilation and heat dissipation unit 142, a fire protection and explosion-proof unit 144, and an emergency shutdown unit 146. It also includes a coolant pump 170, which provides circulating cooling for the electrolytic hydrogen production unit 122 and the hydrogen power generation unit 150. The coolant pump 170 precisely controls the temperature of the electrolytic hydrogen production unit 122 and the hydrogen power generation unit 150, maintaining them within an efficient operating range. The ventilation and heat dissipation, fire protection and explosion-proof, and emergency shutdown units 146 form a multi-layered protection system, quickly responding to dangerous conditions such as hydrogen leakage and high temperatures, ensuring continuous and stable system operation.

[0072] The control device 160 includes an energy management unit 162, a coordination control unit 164, and a safety control unit 168. The energy management unit 162 is used to determine the operating mode, the coordination control unit 164 is used to adjust the operating parameters of each component, and the safety control unit 168 is used to trigger safety protection actions. By clearly defining the functional division of each unit, intelligent determination of the operating mode, dynamic adjustment of component parameters, and precise triggering of safety protection are achieved, realizing coordinated control of the entire "production-storage-generation" chain and improving the system's operating efficiency and reliability.

[0073] The hydrogen electrolysis unit 122 is a proton exchange membrane electrolyzer, which has wide power fluctuation adaptability and rapid start-up and shutdown characteristics. The hydrogen storage container 132 is a high-pressure hydrogen storage container 132, with the inner lining 134 made of metal hydride. The operating pressure of the high-pressure hydrogen storage container 132 is 30MPa-37MPa. The isolation structure 114 is a fire-proof and explosion-proof isolation structure 114, and a fire-proof and explosion-proof isolation structure 114 is also provided between the two sub-sections of the first section 113. The 10kW-class hydrogen gas turbine has rapid start-up and shutdown, low-noise operation, and rapid load response characteristics. The input end of the hydrogen gas turbine is connected to the hydrogen storage container 132 to receive hydrogen released from the hydrogen storage container 132 and convert it into electrical energy. The operating modes include wind and solar power integration mode, grid support mode, and islanded operation mode. When the energy supply is sufficient and the hydrogen storage module 130 has not reached its storage threshold, the energy management unit 162 determines the wind and solar power integration mode, allocating all available wind and solar power to the hydrogen production module 120. When an abnormal grid frequency is detected or a grid dispatch command is received, the energy management unit 162 determines the grid support mode, prioritizing the output power of the hydrogen power generation module 150 to supply active power to the grid. When a grid fault is detected, the energy management unit 162 determines the islanded operation mode, controlling the hydrogen power generation module 150 to switch to V / f control mode to maintain microgrid stability. The adaptive selection of these three operating modes—wind and solar power integration mode, grid support mode, and islanded operation mode—ensures continuous energy supply, maximizing the use of green electricity while responding to unexpected situations such as grid faults. The 10kW-class hydrogen gas turbine is equipped with a fuel valve, and the control device 160 adjusts the opening of the fuel valve to change the hydrogen input rate, simulating the characteristics of a synchronous generator to provide primary frequency regulation. It responds quickly to changes in supply and demand, and is low-noise and environmentally friendly, suitable for multiple scenarios. By regulating the hydrogen input rate through a fuel valve, it simulates the characteristics of a synchronous generator, providing primary frequency regulation for the power grid and improving power supply stability and grid support capabilities. The metal hydride is one or more composite systems selected from LaNi5, TiFe, Mg2Ni, or MgH2. The metal hydride enhances the hydrogen storage density of the high-pressure hydrogen storage container 132 through adsorption-desorption properties.

[0074] The proton exchange membrane electrolyzer's characteristics, namely wide power fluctuation adaptability and rapid start-up and shutdown, can adapt to the intermittent and fluctuating nature of wind and solar energy, quickly respond to power changes, efficiently absorb renewable energy, avoid damage to equipment from sudden power changes, and improve energy utilization efficiency. The 30MPa-37MPa high-pressure design, combined with the adsorption-desorption characteristics of metal hydrides such as LaNi5, significantly improves the hydrogen storage density per unit volume, achieving high-density hydrogen energy storage within the limited space of container 110, meeting multi-day power supply needs. The all-scenario fireproof and explosion-proof isolation structure 114, along with the functional zones 112 and the first zone 113 sub-zone of container 110, all form physical barriers to block the spread of hydrogen-related risks, enhance system safety redundancy, and adapt to scenarios where high-pressure hydrogen-related equipment and precision equipment coexist. Specifically, the energy access module is electrically connected to the backup power supply 172, which is a diesel generator or emergency power supply. The green hydrogen storage device 100 also includes a pressure monitoring unit 136, which can detect the internal pressure of the hydrogen storage container 132.

[0075] like Figure 3 As shown, an embodiment of this application provides a control method for a green hydrogen energy storage device, used in the green hydrogen energy storage device described above. The green hydrogen energy storage device further includes an energy access module. The control method for the green hydrogen energy storage device includes the following steps:

[0076] Step 202: Obtain the pressure parameters of the hydrogen storage module, the operating power parameters of the hydrogen production module, the load demand parameters of the hydrogen power generation module, and the energy supply status parameters.

[0077] Step 204: The operating power of the hydrogen production unit or the hydrogen input rate of the hydrogen power generation unit is adjusted by the control device according to the pressure parameters and energy supply status parameters.

[0078] Step 206: Monitor the safety status parameters of the hydrogen storage component. When the safety status parameters reach the set threshold, trigger the safety protection action.

[0079] This application provides a control method for a green hydrogen energy storage device, used in the green hydrogen energy storage device described in the above embodiments. The green hydrogen energy storage device further includes an energy access module. The control method includes acquiring pressure parameters of the hydrogen storage component, operating power parameters of the hydrogen production component, load demand parameters of the hydrogen power generation component, and energy supply status parameters; adjusting the operating power of the hydrogen production component or the hydrogen input rate of the hydrogen power generation component based on the pressure parameters and energy supply status parameters using a control device; monitoring the safety status parameters of the hydrogen storage component, and triggering a safety protection action when the safety status parameters reach a set threshold. The control method for the green hydrogen energy storage device proposed in this application comprehensively acquires key parameters such as the pressure of the hydrogen storage module, the operating power of the hydrogen production module, the load demand of the hydrogen power generation module, and the energy supply status. This provides the control device with precise decision-making basis, enabling it to dynamically adjust the operating power of the hydrogen production module or the hydrogen input rate of the hydrogen power generation module based on real-time operating conditions. This achieves precise matching between energy supply and hydrogen storage status, efficiently absorbing renewable energy and avoiding problems such as hydrogen overpressure or insufficient power supply. Furthermore, by monitoring the safety status parameters of the hydrogen storage module in real time and triggering safety protection actions when the set threshold is reached, a closed-loop control logic of "data acquisition - dynamic regulation - safety protection" is constructed. This ensures that the device operates intelligently, efficiently, and safely under multiple operating conditions, perfectly adapting to diverse application scenarios such as wind and solar power integration, grid support, and islanded operation.

[0080] In one embodiment of this application, adjusting the operating power of the hydrogen production component or the hydrogen input rate of the hydrogen power generation component by means of a control device based on pressure parameters and energy supply status parameters includes: when the pressure parameter is higher than a first preset pressure value, the control device sends a power reduction command to the hydrogen production component or sends a start command to the hydrogen power generation component; when the pressure parameter is lower than the first preset pressure value, the control device sends a power reduction command to the hydrogen power generation component or sends a supplementary power hydrogen production command to the energy access module to switch to backup power supply for hydrogen production; when the output power of the wind power and photovoltaic generator is lower than the minimum load threshold of the electrolysis hydrogen production device, the control device controls the energy access module to switch to grid or backup power supply to maintain the operation of the hydrogen production component.

[0081] In this embodiment, the control logic of this application achieves dynamic balance of hydrogen storage system pressure by precisely regulating hydrogen storage pressure and energy supply status in different scenarios. When the pressure is higher than the first preset pressure value, the hydrogen production power is reduced or the power generation is started to consume hydrogen to avoid the risk of hydrogen overpressure. When the pressure is lower than the first preset pressure value, the hydrogen consumption is reduced by reducing the power generation output or supplementing the hydrogen reserve by generating hydrogen through electricity, ensuring that the hydrogen storage status is always in a safe and efficient range. It can also adapt to the fluctuation of energy supply. When the wind and solar output power is lower than the minimum load threshold of the electrolysis hydrogen production device, the operation of the hydrogen production components is maintained by switching the grid or backup power supply, avoiding the efficiency decay or equipment damage caused by low load operation of the hydrogen production device. At the same time, it ensures that the hydrogen production process is uninterrupted, realizing the synergy of efficient consumption of renewable energy and flexible supplementation of external energy, further enhancing the stability, safety and continuity of energy utilization of the system operation, and enabling the green hydrogen energy storage device to operate reliably under complex and ever-changing energy supply and load demand conditions.

[0082] In one embodiment, the control method of the green hydrogen energy storage device of this application includes an energy access module electrically connected to a backup power source, which is a diesel generator or an emergency power source. The energy access module also includes a renewable energy access interface for connecting photovoltaic modules and / or wind power generation modules.

[0083] Meanwhile, the control method for the green hydrogen energy storage device includes safety parameters such as hydrogen concentration, smoke concentration, and equipment temperature. Safety protection actions include: when the hydrogen concentration reaches the first-level alarm threshold, increasing the exhaust fan speed of the ventilation and heat dissipation unit; when the hydrogen concentration reaches the second-level alarm threshold, triggering an audible and visual alarm, and simultaneously cutting off the operation of the hydrogen production component and the hydrogen power generation component, as well as the hydrogen supply; when the smoke concentration or equipment temperature reaches a dangerous threshold, cutting off all power and hydrogen sources, and activating the fire extinguishing system of the fire-fighting and explosion-proof unit. This control method, through optimized energy access configuration and hierarchical safety protection design, achieves a dual improvement in both flexible energy supply adaptation and precise control of safety risks. From the perspective of energy supply, the energy access module directly connects to photovoltaic modules and wind power generation modules through renewable energy access interfaces to maximize the utilization of green electricity resources, which is in line with the core positioning of green hydrogen energy storage. It also builds a power supply mode with green electricity as the main source and multiple sources as supplementary sources by linking with backup power sources such as diesel generators or emergency power sources and grid interfaces. This ensures that when the output power of wind and solar power is insufficient or below the minimum load threshold of the electrolysis hydrogen production unit, hydrogen can still be continuously produced through backup power sources, avoiding interruption in the hydrogen production process and ensuring the continuity of hydrogen energy storage. From a safety perspective, the safety status parameters precisely cover core risk points such as hydrogen leakage (hydrogen concentration), fire hazards (smoke concentration), and equipment abnormalities (equipment temperature). The corresponding graded safety protection actions form a gradient protection: when a level one alarm occurs, the hydrogen is quickly diluted through the ventilation and heat dissipation unit; when a level two alarm occurs, the hydrogen-related and electrical operation links are promptly cut off and an early warning is issued; when the danger threshold is reached, the ultimate protection is activated to cut off all power and hydrogen sources and trigger fire extinguishing. This not only avoids the limitations of a single protection mode but also responds precisely according to the risk level. Under the premise of ensuring the safety of personnel and equipment, it reduces the impact of unnecessary shutdowns on system operation. Ultimately, it allows the green hydrogen energy storage device to maintain a stable, reliable, and safe operating state under complex energy conditions and potential safety risks.

[0084] like Figure 4 As shown, an embodiment of this application provides a control device 300 for a green hydrogen energy storage device, used to execute the control method of the green hydrogen energy storage device described in the above embodiment. The control device 300 includes: a first control module 302, a second control module 304, and a third control module 306. The first control module 302 is used to acquire the pressure parameters of the hydrogen storage component, the operating power parameters of the hydrogen production component, the load demand parameters of the hydrogen power generation component, and the energy supply status parameters. The second control module 304 is used to adjust the operating power of the hydrogen production component or the hydrogen input rate of the hydrogen power generation component according to the pressure parameters and energy supply status parameters through the control device. The third control module 306 is used to monitor the safety status parameters of the hydrogen storage component, and trigger a safety protection action when the safety status parameters reach a set threshold.

The third control module 306 is used to monitor the safety status parameters of the hydrogen storage component. When the safety status parameters reach a set threshold, a safety protection action is triggered, realizing a closed-loop coordination of accurate parameter acquisition, dynamic operation control, and timely safety protection. This provides comprehensive and reliable data support for control decisions, can quickly adapt to changes in operating conditions to optimize system operating efficiency, and accurately prevent and control safety risks, ensuring the intelligent, efficient, and stable operation of the green hydrogen energy storage device.

[0086] like Figure 5 As shown, an embodiment of this application provides a control device 400 for a green hydrogen energy storage device, including a processor 402 and a memory 404. The memory 404 stores programs or instructions. When the processor 402 executes the programs or instructions in the memory 404, it implements the steps of the control method for the green hydrogen energy storage device as described in the above embodiment. Therefore, the control device 400 for the green hydrogen energy storage device possesses all the beneficial effects of the control method for the green hydrogen energy storage device as described in the above embodiment.

[0087] The embodiments of this application provide a readable storage medium on which a program or instructions are stored. When the program or instructions are executed by a processor, they implement the steps of the control method for the green hydrogen energy storage device as described in the above embodiments. Therefore, the readable storage medium possesses all the beneficial effects of the control method for the green hydrogen energy storage device as described in the above embodiments.

[0088] In one embodiment, taking a 10kW green electricity hydrogen production and storage power bank as an example, this system uses a 40-foot standard container as an integrated packaging carrier, internally integrating three core subsystems and supporting auxiliary systems:

[0089] Hydrogen production subsystem: One set of proton exchange membrane electrolyzer with a rated hydrogen production capacity of ≥2 Nm³ / h, which has wide power fluctuation adaptability and fast start-up and shutdown characteristics;

[0090] Hydrogen storage subsystem: 1 high-pressure hydrogen storage tank with a working pressure of 30MPa (effective volume of 100L, lined with metal hydride adsorption material), equipped with pressure monitoring unit and multi-stage safety valve;

[0091] Hydrogen power generation system: 1 set of pure hydrogen gas turbine module with rated output of 10kW and AC / DC converter, with fast start-stop, low noise and fast load response characteristics;

[0092] Auxiliary systems include energy conversion, control and protection, ventilation and heat dissipation, emergency response, fire protection and explosion protection systems.

[0093] The system is equipped with a 15kW photovoltaic array and a 5kW wind turbine, and has the ability to operate in both grid-connected and off-grid modes. It also supports remote start-stop and status monitoring.

[0094] Based on the principles of safety isolation and process optimization, the container is divided into an electrical and control area, a power generation and conversion area, a hydrogen production and storage area (explosion-proof focus), and a heat dissipation and protection area. Each area is physically separated by fireproof and explosion-proof walls.

[0095] Hydrogen production and storage area: Proton exchange membrane electrolyzers and high-pressure hydrogen storage tanks are arranged. The hydrogen storage tanks are fixed by a structural frame and equipped with anti-collision protection, and follow the safety distance requirements.

[0096] Power generation and conversion area: pure hydrogen gas turbine is installed, and vibration reduction and sound insulation devices are installed between the modules and the enclosure to meet vibration and heat dissipation requirements;

[0097] Electrical and Control Area: Equipped with control and protection cabinets and intelligent control platforms; the area is clean, has low vibration, and facilitates cable routing and maintenance.

[0098] Heat dissipation and protection area: Ventilation radiators and coolant pumps are installed, and air inlets / outlets are set in key locations to prevent hydrogen accumulation.

[0099] The control logic is divided into a three-layer architecture: management layer, coordination layer, and device layer. A detailed control logic block diagram is shown below. Figure 6 As shown, it includes:

[0100] Management layer (energy management system): includes data acquisition and monitoring, forecasting module, optimization and decision engine, and operation mode state machine. It takes into account information such as grid power forecast and hydrogen storage tank status, outputs total power setpoint and operation mode (wind and solar integration, grid support, islanded operation), and transmits instructions to the coordination layer.

[0101] Coordination layer (real-time power coordination controller): includes modules such as power balance calculator and grid frequency droop controller, receives instructions from the management layer and status feedback from each subsystem, and outputs specific control instructions to the device layer;

[0102] Equipment layer: This layer encompasses core equipment such as electrolyzers, hydrogen storage tanks, and hydrogen gas turbines. It executes commands from the coordination layer, provides real-time operational data feedback, and implements status monitoring and risk protection through a safety system. Closed-loop control is achieved between layers via a link between "power setpoint - status feedback" and "specific control commands - real-time operational data."

[0103] like Figure 7 As shown, Figure 7 The curve shows the variation of the input power (P_ele) of the electrolyzer over time, exhibiting a clear diurnal cycle (5kW–10kW in the early morning, peak at noon of 35kW–40kW, and a decrease at night), superimposed with ±2kW random fluctuations, reflecting the randomness of wind and solar resources and the periodicity of sunshine; the curve has no stagnant area, verifying the system's effective tracking capability for fluctuating power sources, and its ability to absorb renewable energy in the long term.

[0104] like Figure 8 As shown, Figure 8 The temperature (T_ele) curve of the electrolytic cell shows that the temperature monotonically increases from 25℃ to 57℃ as the power increases, and then slowly decreases after the power decreases. It remains within the PEM electrolysis comfort zone of 25℃–60℃ without overshoot or oscillation, demonstrating the stable control capability of the cooling system.

[0105] like Figure 9 As shown, Figure 9 The figure shows the efficiency (η_ele) curve of the electrolyzer. At high power, the efficiency remains at a high level of 0.95–0.98, while fluctuations occur in the low power region (a typical characteristic of PEM electrolyzers). This indicates that the system has better energy conversion efficiency in the high load region, and power smoothing is needed to avoid efficiency loss at low load.

[0106] like Figure 10 As shown, Figure 10 The hydrogen production rate (r_H2) curve has a shape that is highly consistent with the electrolysis power (peak value at noon: 0.08–0.09 mol / s), and its fluctuations are synchronized with the wind and solar power, reflecting the dynamic matching between hydrogen production capacity and power, with no energy bottleneck.

[0107] like Figure 11 As shown, Figure 11 The pressure curve of the hydrogen storage tank (P_tank) shows a "decrease-rise-decrease" change (the pressure decreases slowly from 0h to 10h due to insufficient hydrogen supply from wind and solar power, rises from 10h to 19h due to peak hydrogen production, and decreases slightly after 19h due to a decrease in hydrogen production), with a stable range of 30MPa–37MPa, reflecting the rationality and safety of the hydrogen storage system's "charge-discharge" cycle.

[0108] like Figure 12 As shown, Figure 12 The curve represents the gas turbine inlet mass flow rate (G_mass), which is between 6.2 × 10⁻⁶. -4 kg / s – 7.1 × 10 -4 kg / s, the curve is smooth without abrupt changes, consistent with load changes, reflecting the stability of combustion air-fuel ratio control.

[0109] like Figure 13 As shown, Figure 13The output power (λ_gen) curve of the gas turbine shows an initial instantaneous value close to 10kW, followed by a slight fluctuation between 7kW and 7.3kW, reflecting the unit's rapid start-up and shutdown capabilities and load steady-state control.

[0110] like Figure 14 As shown, Figure 14 The curve for the gas turbine turbine power (λ_turb) is stable in the range of 26kW–27.5kW, showing a fixed proportion to the power generation, reflecting the stability of the turbine mechanical efficiency.

[0111] like Figure 15 As shown, Figure 15 The exhaust temperature (T_exhaust) curve of the gas turbine varies between 1040K and 1135K, fluctuating synchronously with the load without any abnormal sudden changes, reflecting the stability of the combustion process and the safety of the heat engine.

[0112] The system outputs 12kW from photovoltaic power and 2kW from wind power. The electrolyzer operates at full load (hydrogen production rate 1.8Nm³ / h). The hydrogen is compressed and stored in a hydrogen storage tank. When the tank pressure rises to 28MPa, the system automatically reduces the electrolysis power to avoid overpressure.

[0113] When the system switches to power generation mode, the hydrogen in the hydrogen storage tank is depressurized and then drives the gas turbine. The efficiency is greater than 50% at the rated output of 10kW, the hydrogen consumption rate is 3.6Nm³ / h, and it can run continuously for more than 5 hours. It can respond to a step load of 5kW-10kW within 5 seconds, and the voltage fluctuation is less than ±5%.

[0114] If wind and solar power remain scarce and hydrogen storage is insufficient, the system will automatically switch to the power grid / backup diesel generator to produce hydrogen, ensuring hydrogen storage and filling. The equipment operates at a noise level of less than 65dB (at 1m) and has no harmful emissions, making it suitable for remote areas, emergency rescue and other scenarios.

[0115] The 10kW green electricity hydrogen production and storage power bank provided in this application achieves closed-loop operation of "green electricity hydrogen production - hydrogen energy storage - hydrogen energy power generation" through container-integrated design, three-layer control logic and multi-system collaboration. It has good environmental adaptability, safety and reliability, and can provide green, quiet and sustainable power solutions for areas without electricity / with weak electricity, emergency power supply scenarios and mobile microgrids.
