[0002] As a representative of clean energy, hydrogen energy has the advantages of high energy density and zero emissions, but efficient and safe hydrogen storage technology has always been a key challenge for the large-scale application of hydrogen energy. At present, hydrogen storage technology mainly includes three forms: gaseous hydrogen storage, liquid hydrogen storage and solid hydrogen storage. Compared with gaseous and liquid hydrogen storage, solid hydrogen storage has attracted much attention due to its safety and high hydrogen storage density.
[0003] Hydrate storage is a special solid-state hydrogen storage method that combines hydrogen with water molecules under certain temperature and pressure conditions to form solid hydrogen hydrates. This method has the following characteristics: harsh generation conditions, kinetic limitations, insufficient material optimization, and limited control accuracy.

Figures 1 to 4The method for controlling solid-state composite hydrogen storage of hydrates includes: step S101: obtaining a set temperature curve and a set pressure curve corresponding to the inner tank where the hydrogen hydrate is located; wherein the set temperature curve and / or the set pressure curve are configured as a periodic curve; step S102: determining at least one of the hydrogen filling and hydrogen hydrate generation phase, the temperature rise and pressure reduction phase, the cooling and pressurization phase, and the hydrogen release phase in the process of controlling solid-state composite hydrogen storage of hydrates; step S103: in at least one of the hydrogen filling and hydrogen hydrate generation phase, the temperature rise and pressure reduction phase, the cooling and pressurization phase, and the hydrogen release phase, rhythmic control is performed on the solid-state composite hydrogen storage of hydrates by regulating the temperature initial value of the set temperature curve and the pressure initial value of the set pressure curve. This is to solve at least one of the technical problems of harsh generation conditions, kinetic limitations, insufficient material optimization, limited control accuracy, and the fact that the prior art relies on a single constant condition to control temperature and pressure, which makes it difficult to dynamically respond to complex working conditions, resulting in excessive energy consumption and low efficiency.
[0071] Step S101: obtaining a set temperature curve and a set pressure curve corresponding to an inner tank where hydrogen hydrate is located; wherein the set temperature curve and / or the set pressure curve are configured as periodic curves.
[0072] In the embodiments of the present disclosure and other possible embodiments, the set temperature curve and / or the set pressure curve are configured as periodic curves. For example, the periodic curve can be configured as a periodic curve corresponding to all trigonometric functions such as sin x, cos x, tan x, cot x, etc. For another example, the periodic curve can be configured as a periodic curve corresponding to periodic functions such as triangular waves and rectangular waves. For another example, for other possible functions f(x), for function f(x), if there is a constant T that is not 0, so that for any x in the definition domain, f(x+T)=f(x), then function f(x) is a periodic curve corresponding to a periodic function.
[0073] In the embodiments of the present disclosure and other possible embodiments, the following embodiments are described using a periodic curve corresponding to the sin x trigonometric function. For example, in a rhythmic pressure-temperature cycle, the temperature and pressure of the inner tank of the hydrogen storage bottle are adjusted according to the following function:
[0074] T(t)=T 初始 +ΔT amp ·sin(2πf T t)

[0084] In the embodiment of the present disclosure and other possible embodiments, after hydrogen is filled into the inner tank 3 of the hydrogen storage bottle and enters the hydrogen hydrate generation stage, the hydrogen is discharged through the air inlet 13 at a rate of 10 standard cubic meters (Nm3) per minute. 3 / min) (set hydrogen inlet rate), slowly introduces hydrogen, and enters the inner tank 3 after being filtered by the gas filter 12, and contacts with the responsive hydrate builder 4 in the inner tank 3 of the hydrogen storage bottle. Real-time adjustment is made according to the set temperature curve T(t) and the set pressure curve P(t) to ensure uniform adsorption of hydrogen and stable formation of hydrates. The adaptive dynamic fuzzy logic hybrid controller raises the pressure of the inner tank 3 to the initial pressure value P0=10MPa, and starts to execute the rhythmic control strategy, so that the temperature and pressure of the inner tank 3 of the hydrogen storage bottle change synchronously according to the set temperature curve and the set pressure curve.

[0093] In the embodiment of the present disclosure and other possible embodiments, in the cooling and pressurizing stage (the third cycle pressure and temperature), the adaptive dynamic fuzzy logic hybrid controller increases the refrigerant flow rate by adjusting the refrigerant inlet, and adjusts the initial value T of the temperature of the inner tank 3 of the hydrogen storage bottle. 初始 The temperature of the inner tank 3 of the hydrogen storage bottle is maintained within the range of T 初始 -ΔT amp To T 初始 +ΔT amp At the same time, the hydrogen input of the air inlet 13 is adjusted again, and the pressure of the inner tank 3 of the hydrogen storage bottle is maintained within the range of P0-ΔP by increasing the pressure from the first set pressure target value to the second set pressure target value (for example, to 12MPa). amp To P0+ΔP amp In between, the incompletely reacted hydrogen is further converted into hydrogen hydrate.
[0094] In the embodiment of the present disclosure and other possible embodiments, the adaptive dynamic fuzzy logic hybrid controller sets hysteresis zones for temperature and pressure to prevent frequent switching of control modes and improve energy efficiency.
[0095] In the embodiment of the present disclosure and other possible embodiments, the above two stages of heating and depressurizing and cooling and pressurizing constitute a cycle of pressure and temperature. According to the demand, the cycle of pressure and temperature can be repeated many times to make the amount of hydrogen adsorbed tend to saturation.
[0096] In the embodiments of the present disclosure and other possible embodiments, the further reduction of temperature and the increase of pressure strengthen the stability of the hydrate lattice, promote the adsorption of the remaining hydrogen molecules and the further formation of hydrates. The hydrate lattice vibration is more orderly under high pressure and low temperature conditions, ensuring that the hydrogen molecules are effectively locked in the lattice structure, and improving the density and safety of hydrogen storage.

[0098] In an embodiment of the present disclosure, after each of the temperature rising and pressure reducing phases or each of the cooling and pressure increasing phases, the hydrogen storage capacity increment between this cycle and the previous cycle and the pressure increasing phases is calculated; if the hydrogen storage capacity increment is less than a set hydrogen storage capacity increment threshold and / or the actual hydrogen storage capacity of the inner tank reaches a set hydrogen storage capacity target and / or a preset maximum number of cycles corresponding to the set hydrogen storage capacity target, the cycle and the pressure increasing phases or the temperature rising and pressure reducing phases or the cooling and pressure increasing phases are stopped, and the static pressure and temperature phase is entered.

Each cycle promotes the rearrangement and optimization of the hydrate lattice, ensuring the efficient embedding and stable storage of hydrogen molecules in the structure of the hydrate lattice.
[0101] In the embodiments of the present disclosure and other possible embodiments, the basis for controlling the number of cycles is hydrogen adsorption saturation: by real-time monitoring of the pressure and temperature changes of the inner tank 3, it is determined whether the hydrogen adsorption has reached a saturated state. After multiple cycles of pressure and temperature, the amount of hydrogen adsorption tends to be stable, and the fluctuation amplitude of the pressure and temperature of the inner tank 3 is reduced, which means that the saturation state is reached and the circulation is stopped. System performance indicators: set a hydrogen storage capacity target. When the actual hydrogen storage capacity of the inner tank 3 in the system reaches more than 95% of the design capacity (that is, the set hydrogen storage capacity target), stop the pressure and temperature circulation. By regularly detecting the set hydrogen storage capacity target corresponding to the adsorption performance of the responsive hydrate builder 4, it is ensured that its pore structure has been fully utilized. Preset value of the number of cycles: according to experimental data and system design analysis, set a preset maximum number of cycles corresponding to the hydrogen storage capacity target (such as 10 times) to prevent excessive cycling from causing system fatigue or material damage. When the preset number of cycles or saturation is reached, the circulation is automatically stopped. Energy efficiency considerations: monitor the energy consumption of each cycle.
