[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] It is to be noted that, in the present text, relational terms such as "first", "second" and the like can merely be used to distinguish one entity or action from another, without necessarily requiring or implying any actual such relationship or order between or among the entities or actions. Also, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element preceded by "comprises a" does not, without more constraints, foreclose the existence of additional identical elements in the process, method, article, or apparatus that comprises the recited element.

[0031] Referring to Figure 1 The present application provides a solid-state hydrogen storage charging and discharging decoupling system based on a heat collection field, which comprises an energy management system (i.e. a control system) and a hydrogen production system 18, a solar heat collection system 1 (including an electric heating device 17), a hydrogen storage system 4, a hydrogen release system 5, a cooling system (mainly a chilled water unit 14), and a steam power generation device connected with the energy management system. The hydrogen storage system 4 is in a decoupling relationship with the hydrogen release system 5, and the two are connected for heat exchange, i.e. the hydrogen storage system 4 provides heat energy for the hydrogen release system 5.

[0032] The solar heat collection system 1 can adopt a disc type, tower type, or trough type solar heat collector array, or a parabolic trough type solar heat collector array. The solar heat collector array focuses sunlight on a vacuum heat collection pipe at a focal line, and a working medium (such as heat conducting oil) in the vacuum heat collection pipe absorbs heat and increases in temperature. The solar heat collector array can maximize the reception of solar radiation and improve the collection efficiency of solar energy through reasonable layout and angle adjustment.

[0033] The solar heat collection system 1 converts solar energy into heat energy, and uses a working medium external pump 3 to transport the heat energy to the hydrogen storage system 4 and the hydrogen release system 5 through a working medium high-temperature tank 2. The transported heat energy preheats, increases, and maintains the temperature of the hydrogen storage system 4 and the hydrogen release system 5. The hydrogen storage system 4 and the hydrogen release system 5 are connected with the solar heat collection system 1 through a working medium low-temperature tank 10, and the heat conducting oil used in the hydrogen storage system 4 and the hydrogen release system 5 can be introduced into the solar heat collection system 1 for recycling, thereby greatly improving the energy utilization efficiency.

[0034] The energy management system controls the direction of heat energy transmission according to the operating state of the hydrogen storage system 4 and the hydrogen release system 5. The energy management system adopts an intelligent control system based on a programmable logic controller (PLC); the system collects the operating parameters of the solar heat collection system 1, the hydrogen production system 18, the hydrogen storage system 4, the hydrogen release system 5, the steam power generation device, and the cooling system in real time through temperature sensors, pressure sensors, flow sensors, etc. The energy management system controls the valve switching and opening and closing degree, the power of the electric heating device, the operating state of the steam compressor and the working medium delivery pump in the system according to the preset control strategy, and realizes precise control of the hydrogen charging and discharging process of the system. In some embodiments, the energy management system has a fault diagnosis and early warning function, which can timely issue an alarm and take corresponding protective measures when the system has abnormal conditions (such as excessively high temperature, excessively low flow rate, abnormal pressure, etc.), to ensure the safe and stable operation of the system.

[0035] The hydrogen storage temperature of the solid-state hydrogen storage material (magnesium alloy) of the hydrogen storage system 4 is 150-250°C, and the hydrogen storage temperature of the solid-state hydrogen storage material (hydrogen-magnesium alloy) of the hydrogen release system 5 is 250-350°C. The energy management system monitors and regulates the operating parameters of the entire system in real time to ensure stable and efficient operation of the system.

[0036] In the hydrogen storage stage, the hydrogen storage system 4 is operated and the hydrogen release system 5 is not operated. When the heat transmitted by the solar heat collection system 1 is higher than the temperature required for the hydrogen charging of the hydrogen storage system 4, i.e. 150-250°C, the energy management system adjusts the excess heat through the valve to the hydrogen release system 5 and the working medium low-temperature tank 10. The heat transferred to the hydrogen release system 5 is used to preheat the magnesium hydride alloy material and heat the hydrogen release reaction chamber of the hydrogen release system 5, thereby improving the energy utilization efficiency. The heat transferred to the working medium low-temperature tank 10 through the working medium internal pump 19 slowly increases the temperature of the working medium in the low-temperature tank, balances the heat loss of the system, and further shortens the warming-up time of the solar heat collection system 1.

[0037] Please refer to Figure 1 and Figure 2 , the hydrogen storage system 4 includes a hydrogen storage storage bin, a hydrogen storage material preheating bin, a hydrogen storage reaction bin, a hydrogen storage cooling bin, a hydrogen storage discharge bin, and a hydrogen gas preheating bin. The heated working medium is stored in the working medium high-temperature tank 2, and the high-temperature working medium is introduced into the hydrogen gas preheating bin and the hydrogen storage material preheating bin of the hydrogen storage system 4 by the working medium external pump 3 to heat the medium in the bins. The magnesium alloy material in the hydrogen storage material preheating bin and the hydrogen gas in the hydrogen gas preheating bin are preheated and then introduced into the hydrogen storage reaction bin which has been purged with argon and vacuumized according to the sequence. Then, the preheated hydrogen gas is continuously blown into the hydrogen storage reaction bin to control the temperature of the bin body and the internal material until the magnesium alloy and the hydrogen gas start to release heat, and the heating of the hydrogen gas preheating bin is stopped.

[0038] In the embodiment of the present application, the hydrogen storage reaction bin is connected with the first steam generator 11 through the first heat exchanger pump 12, the solar heat collection system 1 comprises an electric heating device 17 (a thermal energy auxiliary element) and an energy storage device 16, the first steam generator 11 comprises a steam generator 20, and the electric heating device 17 is connected with the steam generator 20 of the first steam generator 11. The heat generated by the hydrogen storage system 4 is converted into electric energy by the first steam generator 11, and then the electric heating device 17 is provided with thermal energy for heating the working medium in the working medium high-temperature tank 2. During the hydrogen storage reaction, the energy management system starts the first heat exchanger pump 12 to consume the excess heat generated by the hydrogen storage reaction bin through the first steam generator 11, and generates the steam generator 20 to discharge to the electric heating device 17, and the excess electric energy is stored in the energy storage device 16. When the heat delivered by the solar heat collection system 1 is insufficient, the electric heating device 17 is started to heat the heat conducting oil, so that the hydrogen storage system 4 reaches the hydrogen charging temperature.

[0039] Further, the hydrogen storage cooling bin is also connected with the second steam generator 15 through the second heat exchanger pump 6, the second heat exchanger pump 6 converts the heat generated by the hydrogen storage material in the hydrogen storage cooling bin into electric energy through the second steam generator 15, and then provides the electric heating device 17 with thermal energy for heating the working medium in the working medium high-temperature tank 2. After the hydrogen storage is completed, the hydrogen storage material (magnesium alloy, which becomes hydrogen magnesium alloy after reaction) in the hydrogen storage reaction bin stores the planned hydrogen amount, and then the hydrogen magnesium alloy is introduced into the hydrogen storage cooling bin. The energy management system starts the second heat exchanger pump 6 to consume the heat of the hydrogen magnesium alloy through the second steam generator 15 and the cooling system, and then introduces the hydrogen magnesium alloy into the discharge bin.

[0040] In the hydrogen release stage, the hydrogen storage system 4 does not operate. By using the characteristics of the magnesium alloy material for hydrogen storage and heat release and the requirement of temperature reduction for discharging the material, part of the heat is used for preheating the magnesium alloy material, reducing the heat consumption of the hydrogen storage system 4 itself; part of the heat is fed back to the circulation loop of the solar heat collection system 1 through the heat exchange pipeline, improving the overall efficiency of the solar heat collection system, and the remaining heat is converted into steam through the heat exchanger, and then the steam generator 20 is used to generate electricity and store and recycle. According to the temperature requirement of 250-350℃ required by the hydrogen release of the hydrogen storage material in the hydrogen release system 5, the energy management system timely supplements the heat from the solar heat collection system 1, other heat supply devices or heat exchange devices, accurately adjusts the flow and temperature of the heat conducting oil, and delivers appropriate heat to the hydrogen release reaction bin of the hydrogen release system 5, so that the hydrogen release temperature is stably maintained in the required temperature range of the material hydrogen release.

[0041] Please combine Figure 1 with Figure 3As shown, the hydrogen release system 5 includes a hydrogen release storage bin, a hydrogen release material preheating bin, a hydrogen release reaction bin, a hydrogen release cooling bin, and a hydrogen release discharge bin. The heated working medium is stored in the working medium high-temperature tank 2, and the working medium external pump 3 is used to guide the high-temperature working medium into the material preheating bin of the hydrogen release system 5 to heat the hydrogen-magnesium alloy medium in the bin. The hydrogen-magnesium alloy material in the hydrogen release material preheating bin is guided into the hydrogen release reaction bin after preheating, and the hydrogen release reaction bin is subjected to argon blowing and vacuumizing. During the hydrogen release reaction, the energy management system controls the valve to be opened, and the working medium continuously guides heat into the hydrogen release reaction bin to control the temperature of the bin body and the internal material until the hydrogen release is completed. The working medium stops heating the hydrogen release reaction bin, and the hot hydrogen gas released during the hydrogen release is discharged after cooling.

[0042] In the embodiment of the present application, the hydrogen release cooling bin is further connected with the second steam generator 15 through the third heat exchange pump 8. The third heat exchange pump 8 converts the heat generated by the hydrogen release material in the hydrogen release cooling bin into electric energy through the second steam generator 15, and then provides the electric heating device 17 with heat energy for heating the working medium in the working medium high-temperature tank 2. After the hydrogen release is completed, the hydrogen release system 5 guides the magnesium alloy after the hydrogen release of the hydrogen release reaction bin into the hydrogen release cooling bin, and starts the third heat exchange pump 8 to consume the heat of the magnesium alloy material through the second steam generator 15 and the cooling system, and generate steam to drive the steam generator 20 to discharge electricity to the electric heating device 17. The excess electric energy is stored in the energy storage device 16. When the temperature of the magnesium alloy in the hydrogen release cooling bin decreases to the required temperature, the magnesium alloy is guided into the hydrogen release discharge bin to be sent to the system, and the physical and chemical properties of the magnesium alloy tablet are detected.

[0043] Further, the hydrogen release preheating bin is connected with the second heat exchange pump 6. When the hydrogen storage system 4 and the hydrogen release system 5 are operated simultaneously, the second heat exchange pump 6 transports the heat generated by the hydrogen storage system 4 during the hydrogen storage to the hydrogen release preheating bin for preheating the hydrogen release material.

[0044] In addition, in the present application, the hydrogen storage system 4 includes a hydrogen storage storage bin, a hydrogen storage material preheating bin, a hydrogen storage reaction bin, a hydrogen storage cooling bin, a hydrogen storage discharge bin, and a hydrogen gas preheating bin. The hydrogen release system 5 includes a hydrogen release storage bin, a hydrogen release material preheating bin, a hydrogen release reaction bin, a hydrogen release cooling bin, and a hydrogen release discharge bin. The hydrogen storage storage bin, the hydrogen storage material preheating bin, the hydrogen storage reaction bin, the hydrogen storage cooling bin, the hydrogen storage discharge bin, the hydrogen gas preheating bin, the hydrogen release storage bin, the hydrogen release material preheating bin, the hydrogen release reaction bin, the hydrogen release cooling bin, and the hydrogen release discharge bin all include a hydrogen storage material filling layer, a heat conduction layer, and a heat insulation layer arranged from inside to outside. In some embodiments, the heat conduction layer is a copper alloy, and the heat insulation layer is an aerogel material and a heat insulation blanket. A plurality of temperature sensors and pressure sensors are arranged in the interior of each bin to monitor the temperature and pressure changes of the hydrogen storage material in real time, and feed back the data to the control system.

[0045] Based on the above, the application makes full use of the energy of hydrogen storage heat release and cooling heat exchange to provide thermal energy for material preheating and steam power generation, greatly improving energy utilization efficiency.

[0046] Further, as shown in Figure 1 The cooling system includes a first heat exchanger 7 matched with the hydrogen storage cooling bin in the hydrogen storage system 4, a second heat exchanger 9 matched with the hydrogen release cooling bin in the hydrogen release system 5, a third heat exchanger 13 matched with the hydrogen release reaction bin in the hydrogen release system 5, and a chilled water unit 14. The inlet end of the chilled water unit is connected with the second steam generator 15, and the outlet end of the chilled water unit 14 is connected with the first heat exchanger 7, the second heat exchanger 9 and the third heat exchanger 13 respectively. The first heat exchanger 7 is connected with the second heat pump 6, and the second heat exchanger 9 is connected with the third heat pump 8. After the hydrogen storage system 4 is fully charged, the second heat pump 6 delivers the heat generated by the light magnesium alloy to the chilled water unit 14 through the first heat exchanger 7 to consume heat, and after the hydrogen release system 5 is fully discharged, the third heat pump 8 delivers the heat generated by the magnesium alloy to the chilled water unit 14 through the second heat exchanger 9 to consume heat. The hydrogen release system 5 needs to be cooled during hydrogen release, and the third heat exchanger 13 can provide cooling conditions for the hydrogen release reaction bin of the hydrogen release system 5. Based on this, the application efficiently couples the heating and cooling system with the hydrogen storage and release system 5, improves the rate of hydrogen storage and release and the stability of the system through efficient temperature control and heat recovery.

[0047] As described above, the application decouples the hydrogen storage and release units, avoids mutual interference of the two processes, improves the flexibility and reliability of the system, and prolongs the service life of the system.

[0048] Please refer to Figure 4 The application also provides a control method of the solid-state hydrogen storage charging and discharging decoupling system, including the following contents.

[0049] Step 110: According to whether the light condition is sufficient, the solar heat collection system and the electric heating device are used to deliver heat energy to the hydrogen storage system and the hydrogen release system through the working medium high-temperature tank. In the case that the light condition is sufficient, the solar heat collection system is used to provide heat for the heat conduction oil, and the heat energy is released from the working medium heat tank to the hydrogen storage system and the hydrogen release system. In the case that the light condition is not sufficient, the electric heating device is used to assist in providing heat for the heat conduction oil, and the heat energy is released from the working medium heat tank to the hydrogen storage system and the hydrogen release system.

[0050] Step 120: When the hydrogen storage system is running, the control working medium high-temperature tank transports heat energy to the hydrogen storage system and controls the temperature, and the heat energy is introduced into the hydrogen preheating bin and the material preheating bin of the hydrogen storage system to heat the internal medium. Then, the preheated magnesium alloy material and the preheated hydrogen are introduced into the hydrogen storage reaction bin which is purged by argon and vacuumized in sequence to start the first heat pump and the first steam generator to transport the heat energy generated in the hydrogen storage to the electric heating device. The excess electric energy is stored in the energy storage device. After the hydrogen storage is completed, the second heat pump and the second steam generator are started to connect the heat energy generated by the hydrogen storage material to the cooling system. The cooling system and the second heat pump consume the heat energy generated by the hydrogen storage material.

[0051] Step 130: When the hydrogen release system is running, the control working medium high-temperature tank transports heat energy to the hydrogen release system. The working medium heat pump first introduces heat energy into the material preheating bin of the hydrogen release system to heat the internal medium, and then introduces the preheated hydrogen magnesium alloy material into the hydrogen release reaction bin which is purged by argon and vacuumized. The working medium continuously introduces heat into the hydrogen release reaction bin to control the temperature of the bin body and the internal material until the hydrogen release is completed. The working medium stops heating the hydrogen release reaction bin during the period, and the released hot hydrogen gas is discharged from the system after being cooled. After the hydrogen release is completed, the third heat pump and the second steam generator are started to transport the heat energy generated by the hydrogen release material to the electric heating device, and the excess electric energy is stored in the energy storage device. After the temperature of the material in the cooling bin decreases to the required temperature, the material is introduced into the discharge bin and sent out of the system.

[0052] Step 140: When the hydrogen storage system and the hydrogen release system are running, the control working medium high-temperature tank transports heat energy to the hydrogen storage system and the hydrogen release system respectively, and the second heat pump is started to input the heat energy generated by the hydrogen storage system to the hydrogen release reaction bin of the hydrogen release system to preheat the hydrogen magnesium alloy. The hydrogen storage system and the hydrogen release system operate according to the above description of the hydrogen storage system and the hydrogen release system respectively.

[0053] Step 150: When the hydrogen storage or hydrogen release is completed, the working medium in the working medium high-temperature tank flows to the working medium low-temperature tank, and the working medium internal pump is started to transport the working medium in the working medium low-temperature tank to the solar heat collection system or the electric heating device for heat exchange to form a heat energy circulation use.
