Description

Technical Field

[0001] This invention belongs to the field of hydrogen production technology, specifically relating to a wind and solar power hydrogen production device and its hydrogen production method. Background Technology

[0002] Hydrogen energy, as a clean energy carrier, is gradually becoming an important part of the global energy transition due to its high calorific value and zero emission characteristics. Currently, the mainstream hydrogen production technologies include water electrolysis, steam reforming, and biomass gasification. Traditional water electrolysis processes usually rely on grid power, which is relatively inefficient and limited by the renewable nature of the power source. Steam reforming also faces carbon emission issues.

[0003] With the widespread application of renewable energy, wind and solar power hydrogen production technology has gradually attracted attention. Existing hydrogen production systems usually use a combination of wind and solar energy to electrolyze water, but they suffer from low energy conversion efficiency, especially when weather conditions change drastically, poor system stability, and relatively high equipment costs, particularly in terms of electrolyzers and power management systems.

[0004] Therefore, it is necessary to design corresponding technical solutions to address this issue. Summary of the Invention

[0005] This invention provides a hydrogen production device and method using wind and solar power, which solves the problem.

[0008] S2. The distribution of electrical energy is adjusted through an intelligent scheduling system to ensure the optimal working condition of the electrolysis unit;

[0009] S3. Electrical energy is transmitted to the electrolysis unit, where hydrogen and oxygen are produced by electrolyzing water in the electrolytic cell;

[0010] S4. Collect and store the generated hydrogen, while the oxygen can be used as a byproduct or released safely.

[0011] The intelligent scheduling device is internally equipped with a data acquisition module, a data processing module, a scheduling algorithm module, a control execution module, a user interface module, and a cloud logic module.

[0012] Preferably, the wind power generation device adopts a high-efficiency symmetrical wind turbine design to minimize wind resistance and improve power generation efficiency. The angle of the fan blades can be adjusted by an intelligent control system to adapt to wind speeds of different times and increase power generation. The solar power generation uses high-efficiency photovoltaic cells to improve the conversion rate of light energy and is equipped with a two-axis or single-axis tracking bracket to maximize the capture efficiency of sunlight and ensure that the photovoltaic cells are at an optimized angle throughout the entire solar cycle.

[0013] Preferably, the electrolytic hydrogen production device adopts an advanced solid oxide electrolyzer or a proton exchange membrane electrolyzer, and the appropriate type is selected according to the hydrogen production requirements.

[0014] Preferably, the intelligent scheduling device should be able to monitor environmental data (wind speed, light intensity, temperature, etc.) in real time, with a collection frequency of ≥1Hz, and its control algorithm should be able to adjust the scheduling of wind and solar energy in real time within ±5% error to ensure the stable operation of the electrolytic cell.

[0015] Preferably, steps S1 to S4 include the following expansion steps:

[0016] S5: The wind turbine and solar panels monitor environmental conditions in real time to achieve automatic adjustment and maximize output.

[0017] S6. Excess energy is stored in a lithium battery pack with a capacity of 100kWh, which can cope with short-term power generation shortages.

[0018] S7. The system automatically introduces electrical energy into the electrolyzer through the controller to carry out the electrolysis reaction of water and generate hydrogen and oxygen.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This wind and solar power hydrogen production device and its hydrogen production method possess efficient wind energy conversion and solar energy conversion capabilities. Especially under low wind speed (e.g., ≤3m / s) and low light conditions, it can ensure stable system operation, maximize energy capture, and reduce energy loss. The electrolyzer should be highly efficient in responding to variables and have rapid response capabilities to ensure operation even under intermittent continuous power generation conditions, thereby improving operating efficiency. During operation, it should be based on an intelligent control system and an advanced management system to achieve effective energy scheduling and utilization, reduce unnecessary energy waste, and lower long-term operation and maintenance costs. Furthermore, it adopts a modular design to facilitate system disassembly, upgrading, and maintenance, reducing overall maintenance and replacement costs and improving economic feasibility.

[0030] S2. The distribution of electrical energy is adjusted through an intelligent scheduling system to ensure the optimal working condition of the electrolysis unit;

[0031] S3. Electrical energy is transmitted to the electrolysis unit, where hydrogen and oxygen are produced by electrolyzing water in the electrolytic cell;

[0032] S4. Collect and store the generated hydrogen, while the oxygen can be used as a byproduct or released safely.

[0033] The intelligent scheduling device 6 is internally equipped with a data acquisition module 7, a data processing module 8, a scheduling algorithm module 9, a control execution module 10, a user interface module 1, and a cloud logic module 12. The intelligent scheduling device 6 calculates optimized scheduling strategies (e.g., current hydrogen demand and short-term renewable energy output) based on real-time energy demand and forecast data.

[0034] Further elaboration based on the above description: the wind power generation device 1 employs a high-efficiency symmetrical wind turbine design to minimize wind resistance and improve power generation efficiency. The angle of the fan blades can be adjusted via an intelligent control system to adapt to different wind speeds and increase power generation. For solar power generation, high-efficiency photovoltaic cells are selected to improve the conversion rate of light energy. A dual-axis or single-axis tracking bracket is provided to maximize sunlight capture efficiency and ensure the photovoltaic cells maintain an optimized angle throughout the entire solar cycle. When the power generation is greater than or equal to the operating power required by the electrolyzer, the electrolyzer is started to electrolyze water to produce hydrogen. If the battery cannot be charged, the energy storage battery is activated to provide the required power, ensuring stable system operation.

[0035] As further explained above, the electrolytic hydrogen production device 3 adopts an advanced solid oxide electrolyzer or a proton exchange membrane electrolyzer, and the appropriate type is selected according to the hydrogen production requirements.

[0036] As further elaborated by the above description, the intelligent scheduling device 6 should be able to monitor environmental data (wind speed, light intensity, temperature, etc.) in real time, with a collection frequency of ≥1Hz, and its control algorithm should be able to adjust the scheduling of wind energy and light energy in real time within ±5% error to ensure the stable operation of the electrolytic cell.

[0037] Based on the above description, further explanation is provided that S1 to S4 include the following extended steps:

[0038] S5: The wind turbine and solar panels monitor environmental conditions in real time to achieve automatic adjustment and maximize output.

[0039] S6. Excess energy is stored in a lithium battery pack with a capacity of 100kWh, which can cope with short-term power generation shortages.

[0040] S7. The system automatically introduces electrical energy into the electrolyzer through the controller to carry out the electrolysis reaction of water and generate hydrogen and oxygen.

[0041] S8 is designed with a gas separation and purification module. Hydrogen is transported to the storage tank through pipelines, and the storage pressure can reach 30MPa, ensuring safety and high efficiency.

[0042] Working principle: When using this wind and solar power hydrogen production device and its hydrogen production method, a support frame is erected and wind turbines and solar photovoltaic panels are installed at the selected test site to ensure that the wind and solar energy access paths are unobstructed. At the same time, an electrolyzer, energy storage unit and inverter are installed to ensure that the necessary electrical connections are made between the equipment.

[0043] Start the control system, check whether the communication between the sensors, control module and execution unit is normal, conduct separate tests on the wind power and photovoltaic system to ensure normal power generation under various working conditions. After normal operation, the data acquisition module 7 monitors environmental data such as wind speed, light intensity and temperature in real time, and inputs the data into the control system through the data acquisition module 7 to calibrate the scheduling algorithm model and ensure high sensitivity in data input and actual environment.

[0044] Based on environmental data and predictive algorithms, a preliminary working strategy for power generation and hydrogen production is formulated. In environments with high wind speeds and high sunlight, wind and solar power generation are prioritized. When there is an energy surplus, energy is stored in lithium batteries and hydrogen is produced by water electrolysis. The entire system is then started, automatically switching control strategies and providing real-time feedback on the operating status. Visual data is displayed through a user interface, while hydrogen production is monitored, production parameters and equipment performance are recorded, and the system monitoring time is every second. Environmental weather data is acquired in real time, and wind speed and sunlight intensity are recorded.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
