[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0018] Please refer to the attached document. Figures 1-5 This invention proposes a multifunctional mobile energy island, comprising a mobile carrying system 1 and a green energy harvesting system 2, an electrical energy storage and distribution system 3, a water electrolysis hydrogen production system 4, a hydrogen processing system 6, an energy conversion system 7, an energy output system 8, and an intelligent control system 9 transported via the mobile carrying system 1. The green energy harvesting system 2 is used to harvest green electricity and rainwater, wherein the rainwater is used to provide raw water for the water electrolysis hydrogen production system 4. The electrical energy storage and distribution system 3 is used to store and regulate electrical energy, wherein the electrical energy includes green electricity. The system can supply power to the water electrolysis hydrogen production system 4 or the energy output system 8. The water electrolysis hydrogen production system 4 includes multiple AEM electrolyzers 411 connected in parallel and used to produce hydrogen. The hydrogen processing system 6 is used to compress and store the hydrogen. The energy conversion system 7 is used to convert the hydrogen into electrical energy. The energy output system 8 is used to output electrical energy or hydrogen. The intelligent control system 9 is used to control the flow rate of the electrical energy and the hydrogen.

[0019] In this embodiment, a multifunctional mobile energy island includes a mobile carrying system 1 and a green energy harvesting system 2, an electrical energy storage and distribution system 3, a water electrolysis hydrogen production system 4, a public utility system 5, a hydrogen processing system 6, an energy conversion system 7, an energy output system 8, and an intelligent control system 9 transported via the mobile carrying system 1. The green energy harvesting system 2 is installed above the mobile carrying system 1 and includes photovoltaic modules 21 for photovoltaic power generation, wind power modules 22 for wind power generation, and a rainwater collector 23 for collecting rainwater. The rainwater is purified by a water purifier 52 in the public utility system 5 and becomes the raw water for the water electrolysis hydrogen production system 4. Electricity obtained through the conversion of natural resources such as solar and wind energy is green electricity, while electricity directly input through the mains or power grid is external electricity. The electricity storage and distribution system 3 includes an energy storage subsystem 31 and a smart power source 32. The energy storage subsystem 31 is used to store green electricity and external electricity, and to obtain pre-stored electricity. Part of the pre-stored electricity is transmitted to the charging pile 81, and the other part is transmitted to the smart power source 32. The smart power source 32 is used to receive the pre-stored electricity, the external electricity, or the green electricity, and to intelligently adjust and distribute it to the water electrolysis hydrogen production system 4, and to meet the requirements of the water electrolysis hydrogen production system 4 for startup and load variation under high current density conditions under wind and solar fluctuations. The water electrolysis hydrogen production system 4 includes an electrolysis cell subsystem 41, a separation subsystem 42, and a purification subsystem 43. The electrolysis cell subsystem 41 comprises multiple parallel-connected AEM electrolysis cells 411 (Anion Exchange Membrane) for producing hydrogen gas through water electrolysis. The separation subsystem 42 performs gas-liquid separation on the hydrogen gas, removing residual water and alkali. The purification subsystem 43 purifies the hydrogen gas, removing residual oxygen, nitrogen, or other mixed gases to obtain high-purity hydrogen. A portion of the high-purity hydrogen is supplied to the energy conversion system 7, and another portion is supplied to the hydrogen compression subsystem 61. The energy conversion system 7 uses a fuel cell 71 to generate electricity by reacting hydrogen with air or oxygen, and then supplies this electricity to a charging pile 81. The charging pile 81 directly outputs the electricity to provide power for electric vehicles and mobile power supplies. The hydrogen compression subsystem 61 is used to compress the high-purity hydrogen. The compressed high-pressure high-purity hydrogen is partly transported directly to the hydrogen refueling pile 82 and partly transported to the hydrogen storage subsystem 62 for storage. The hydrogen stored in the hydrogen storage subsystem 62 can also be transported to the hydrogen refueling pile 82. The hydrogen refueling pile 82 is used to directly output the hydrogen to provide hydrogen to the gas cylinders of drones or two-wheeled vehicles.

[0020] This invention, by adding a green energy harvesting system 2, enables self-sufficiency in electricity and hydrogen using natural resources such as solar, wind, and rainwater, achieving self-recharging without direct external energy input. The invention integrates and transports the aforementioned energy storage and distribution system 3, water electrolysis hydrogen production system 4, hydrogen processing system 6, energy conversion system 7, and energy output system 8 through a mobile carrying system 1. Intelligent scheduling through an intelligent management and control system 9 enables intelligent control of electricity and hydrogen flow, thereby achieving efficient and continuous external electricity and hydrogen replenishment at non-fixed locations. This invention can provide "electricity + hydrogen" dual-mode replenishment for hydrogen fuel cell trucks, inspection robot dogs, and logistics drones in intelligent transportation energy networks, and is particularly suitable for transportation routes or temporary operation bases without grid coverage. In quiet and sensitive scenarios, its completely silent and zero-emission characteristics make it suitable for environmentally demanding environments such as nature reserves, research camps, and high-end outdoor activities. In emergency and mobile AI infrastructure, it enables rapid deployment in scenarios such as disaster relief, field exploration, and temporary events, providing off-grid power security for critical loads such as communication equipment, AI monitoring systems, and medical instruments. Through multi-energy complementarity and intelligent scheduling, it can be embedded in microgrids in remote areas or industrial parks within distributed microgrid nodes, achieving flexible energy supply and low-carbon upgrades.

[0021] Please refer to Figures 1-5 The green energy collection system 2 is installed above the mobile carrier system 1 and includes a photovoltaic module 21, a wind power module 22 and a water collector 23. The photovoltaic module 21 is used for photovoltaic power generation, the wind power module 22 is used for wind power generation, and the water collector 23 is used for collecting rainwater.

[0022] In practical implementation: The mobile carrier system 1 includes a skid-mounted container and a mobile chassis, which are tightly fixed together by welding or bolts. In one specific embodiment, the skid-mounted container can use a 40GP container (40-foot standard container) as the storage unit for each system, integrating each system onto a mobile platform. The green energy collection system 2 is installed above the mobile carrier system 1 and includes photovoltaic modules 21, wind power modules 22, and water collectors 23. The photovoltaic modules 21 consist of multiple 5-500kW photovoltaic panels and retractable brackets, installed on the top of the container. The photovoltaic panels are used to convert solar energy into electrical energy and can be folded and stored in multiple layers according to specific needs, with the final width being less than the maximum width of the container, facilitating road transportation. The retractable bracket is a bracket that can adjust the angle of the photovoltaic panels. Its basic function is to drive the photovoltaic panels to deflect horizontally by 0-30°, and its enhanced function is to rotate the bracket to track the sun, adjusting the angle and direction in real time according to the sun's position, thereby effectively improving power generation efficiency. The wind turbine assembly 22 consists of multiple small wind turbines of 5-10kW and wind blade heads, used to convert wind energy into electrical energy. The wind turbine assembly 22 is detachably installed on the top of the container, and its wind blade heads can rotate 360° and can be adjusted according to the wind direction, thereby improving power generation efficiency. The water collector 23 is a naturally open water collection tray used to collect rainwater. After the rainwater is purified by the water purifier 52 in the auxiliary system 5, it is used as the raw water for the water electrolysis hydrogen production system 4. The water purifier 52 has a built-in water storage tank that can be used to store rainwater and raw water.

[0023] Please refer to Figures 1-5 The power storage and distribution system 3 includes an energy storage subsystem 31 and an intelligent power supply 32. The energy storage subsystem 31 is used to store the green power and external power, and to obtain pre-stored power. The intelligent power supply 32 is used to receive the pre-stored power or the external power or the green power, and to regulate and distribute it to the water electrolysis hydrogen production system 4.

[0024] In practical implementation: the energy storage and distribution system 3 includes an energy storage subsystem 31 and a smart power supply 32. The energy storage subsystem 31 is a battery energy storage system with a capacity of 100-400kWh, such as lithium battery energy storage or flow battery energy storage. Electricity obtained by converting renewable resources such as solar and wind energy is collectively referred to as green electricity. External electricity supplied directly by mains power or grid power can also be stored in the energy storage subsystem 31. The intelligent power supply 32 can receive the pre-stored electrical energy, the external electrical energy, or the green electrical energy. That is, the intelligent power supply 32 has the function of receiving electrical energy from the energy storage subsystem 31, and also has the function of directly receiving photovoltaic module 21, wind power module 22, and grid power. It directly loads the electrical energy onto the terminals of the AEM electrolyzer 411 in the water electrolysis hydrogen production system 4 to supply power to the AEM electrolyzer 411. The AEM electrolyzer 411 is an anion exchange membrane water electrolysis hydrogen production device. The anion exchange membrane is the core separator. Under the drive of the electric field, the hydroxide anions (OH⁻) generated by water electrolysis will migrate through the anion exchange membrane to achieve water decomposition and efficient separation of hydrogen and oxygen. Finally, hydrogen is generated at the cathode and oxygen is generated at the anode. The whole process does not require high-concentration alkaline solution circulation, making the system simpler and safer to operate.

[0025] Furthermore, the intelligent power supply 32 can intelligently adjust the output voltage and current of the photovoltaic module 21 and wind power module 22 under fluctuating conditions, thereby ensuring that the AEM electrolyzer 411 can meet the high current density conditions for start-up and load changes under fluctuating wind and solar power generation. In a specific embodiment, the intelligent power supply 32 monitors and dynamically regulates the output power of the photovoltaic module 21 and wind power module 22 in real time to address the problem of irregular and non-constant fluctuations in the actual power generation caused by natural conditions, and precisely and intelligently adjusts its own output voltage and current. The parameters provide the AEM electrolyzer with a power supply that matches its operating technical requirements. This control method can effectively ensure that the AEM electrolyzer 411 can meet its high current density start-up technical conditions and achieve reliable equipment start-up even under fluctuating conditions such as irregular start-up and shutdown of wind and solar power sources and sudden power changes. It can also support it to complete smooth load change operations during operation, ensuring that the AEM electrolyzer 411 can operate continuously and stably under the condition of fluctuating power supply from wind and solar renewable energy sources, and providing core power guarantee for the normal hydrogen production process of the water electrolysis hydrogen production system 4.

The hydrogen production capacity of a single AEM electrolyzer 411 is 1-100 Nm³ / h, and the hydrogen production pressure is ≥1.6 MPa. The AEM electrolyzers 411 are connected in parallel and integrated. Multiple AEM electrolyzers 411 comprehensively utilize hydrogen collection pipes, oxygen collection pipes, alkali circulation collection pipes, and nitrogen purging collection pipes, etc. The separation subsystem 42 is suitable for realizing gas-liquid separation, that is, separating hydrogen from residual water and alkali. In one specific embodiment, the separation subsystem 42 is based on a self-developed separation process flow and design, which can achieve efficient gas-liquid separation, reduce system alkali loss, and achieve a hydrogen purity of ≥99.8% after system separation.

This ensures that there are no other mixed gases in the water electrolysis hydrogen production system 4 that could cause an explosion due to mixing with hydrogen, thereby effectively ensuring the safe and stable operation of the water electrolysis hydrogen production system 4. The air compressor 54 is used to provide a driving air source. In a specific embodiment, the air compressor 54 uses air to generate compressed air of 0.4 to 0.8 MPa.
