Description

Technical Field

[0001] The present invention relates to the technical field of clean energy power generation, and in particular, to an energy storage system and method using a heterogeneous pressure energy interactive actuation module. Background Art

[0002] Since people on earth have a great demand for electricity, scientists have exhausted their ability to think of many ways to generate electricity, such as generating electricity through combustion, nuclear fission, nuclear fusion, sunlight, water power, wind power, etc.

[0003] Traditionally, scientists often use burning coal and nuclear energy to generate electricity, but the carbon dioxide after burning and the reaction materials used in nuclear energy reactions are very harmful to the environment. In addition, in order to avoid causing harm to the environment, scientists further use more environmentally friendly solar energy or hydropower for green power generation. Although green power generation may be more environmentally friendly and environmentally friendly, the power generation efficiency is usually affected and limited by the climate and environment, and the cost of power generation is usually expensive. Therefore, if the power generation method is to take into account both environmental protection and good power generation efficiency at the same time, it is very difficult with current technology.

The heterogeneous pressure energy interactive actuation module includes a first container and a second container. The first container forms a first accommodation space to store the first fluid. The second container is arranged on one side of the first container. The second container is connected to the first container. In addition, the second container forms a second accommodation space to store the second fluid. Wherein, when executing the first operation mode, the third fluid is injected into the second accommodation space, so that the third fluid drives the second fluid to flow toward the first accommodation space, and then continuously compresses the first fluid in the first accommodation space until the first fluid acts on the first accommodation space with a predetermined pressure, so that the first container stores the first pressure energy; and when executing the second operation mode, the first fluid continuously expands to drive the second fluid to leak out, so as to convert the first pressure energy into a second pressure energy to drive the converter.

[0017] In order to achieve the functions and purposes of the above-mentioned embodiments or other purposes, the present invention provides a heterogeneous pressure energy interactive actuation storage system. The heterogeneous pressure energy interactive actuation storage system includes a plurality of heterogeneous pressure energy interactive actuation modules, a liquid source, a pump, a converter, a first pipe and a second pipe. Each heterogeneous pressure energy interactive actuation module also includes a first container and a second container. The first container forms a first accommodation space to store a first fluid. The second container is arranged on one side of the first container. The second container is connected to the first container. The second container forms a second accommodation space to store a second fluid. The liquid source stores a third fluid. The pump is arranged between the liquid source and the heterogeneous pressure energy interactive actuation module. The pump regulates the third fluid of the liquid source to enter the heterogeneous pressure energy interactive actuation module. The converter receives and outputs the third fluid. The first pipe forms a third accommodation space. The first pipe has a plurality of connection ports, a first connection port and a third connection port. Each connection port connects each second accommodation space and each third accommodation space. The first connection port and the third connection port are respectively connected to the third accommodation space. The first connection port and the third connection port are formed at two ends of the first pipe. The first connection port is coupled to the first end of the liquid source and the third connection port is coupled to the first end of the converter. The second pipe forms a fourth storage space. A first end of the second pipe is coupled to a second end of the converter and a second end of the second pipe is coupled to a second end of the liquid source. When the first operation mode is executed, the third fluid from the liquid source is injected into the second storage space through the first pipe by the regulation of the pump, so that the third fluid drives the second fluid to flow toward the first storage space and then continuously compresses the first fluid in the first storage space until the first fluid acts on the first storage space with a predetermined pressure, so that the first container stores the first pressure energy; and when the second operation mode is executed, the first fluid continuously expands to drive the second fluid to discharge toward the first pipe, so that the second fluid that converts the first pressure energy into the second pressure energy drives the converter through the first pipe to generate electrical energy, and the third fluid after driving the converter flows back to the liquid source through the second pipe, and the pump injects the third fluid of the liquid source into the heterogeneous pressure energy interactive actuation module again.

[0018] To achieve the above-mentioned purpose or other purposes, the present invention provides a heterogeneous pressure energy interactive actuation module capable of executing a first operating mode and a second operating mode. When executing the first operating mode, the heterogeneous pressure energy interactive actuation module receives a third fluid, and when executing the second operating mode, the heterogeneous pressure energy interactive actuation module connects a converter to push the third fluid toward the converter. The heterogeneous pressure energy interactive actuation module includes a container. The container forms a first accommodating space to store the first fluid and forms a second accommodating space to store the second fluid. Among them, the first accommodating space is connected to the second accommodating space. The capacity size of the first accommodating space changes with the first fluid and the capacity size of the second accommodating space changes with the second fluid. The capacity size of the container is the sum of the capacity size of the first accommodating space and the capacity size of the second accommodating space. When the first operating mode is executed, the third fluid is injected into the second accommodating space, so that the third fluid drives the second fluid to flow toward the first accommodating space, thereby continuously compressing the first fluid in the first accommodating space until the first fluid acts on the first accommodating space to have a predetermined pressure, thereby allowing the first container to store the first pressure energy; and when the second operating mode is executed, the first fluid continuously expands to drive the second fluid to leak out, so as to convert the first pressure energy into a second pressure energy to drive the converter.

[0019] To achieve the above-mentioned purpose or other purposes, the present invention provides a heterogeneous pressure energy interactive actuation energy storage method, comprising step (a), i.e. providing a first fluid in a first container; step (b), i.e. providing a second fluid in a second container; step (c), i.e. connecting the first container and the second container; step (d), i.e. applying a third fluid in the second container to drive the second fluid to compress the first fluid and store the first pressure energy; step (e), i.e. releasing the first pressure energy to drive the second fluid to act on the third fluid and output the second pressure energy; and step (f), i.e. executing steps (d) to (e) to output energy by acting reciprocally between the first pressure energy and the second pressure energy.

[0020] Compared with the traditional way of generating electric energy, the heterogeneous pressure energy interactive actuation module and the energy storage system with heterogeneous pressure energy interactive actuation of the present invention can be a closed circulation system. The present invention uses the substances of the first fluid and the second fluid as the medium for generating pressure energy, and drives the converter (such as the converter) to generate electric energy by storing and releasing the pressure energy. In addition, the loss that may occur during the conversion process (such as heat energy loss) can be quickly compensated by simply replenishing the first fluid or the supplementary fluid. The present invention has at least the following advantages:

[0025] (e) Low maintenance cost: The present invention uses substances that can be easily obtained from the environment, such as water, ambient air, etc. Therefore, when the efficiency is reduced, the original energy storage and release efficiency can be restored simply by replenishing at least one of the first fluid, the second fluid and the third fluid, without the need to purchase natural gas, coal, nuclear materials, etc.

[0041] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific embodiments and in conjunction with the accompanying drawings, as follows:

[0042] In the present invention, "a" or "an" is used to describe the units, elements and components described herein. This is only for convenience of description and to provide a general meaning to the scope of the present invention. Therefore, unless it is obvious that it is otherwise intended, such description should be understood to include one, at least one, and the singular also includes the plural.

[0043] As used herein, the terms "comprises," "including," "having," "containing," or any other similar terms are intended to cover a non-exclusive inclusion. For example, an element, structure, article, or device containing multiple elements is not limited to those listed herein but may include other elements not expressly listed but generally inherent to the element, structure, article, or device. In addition, unless expressly stated to the contrary, the term "or" refers to an inclusive "or" and not to an exclusive "or."

[0044] In the following embodiments, the first fluid is described by taking the initial gas IG as an example; the second fluid is described by taking the initial liquid IL as an example; and the third fluid is described by taking the working liquid WL as an example. In other embodiments, the first fluid, the second fluid and the third fluid can be selected as gas, liquid, solid that can evaporate into gas or solid that can dissolve into liquid according to the situation.

[0045] Please refer to Figure 1 , is a three-dimensional schematic diagram of a heterogeneous pressure energy interactive actuation module according to a first embodiment of the present invention. Figure 1 In the embodiment, the heterogeneous pressure energy interaction actuation module 10 can execute the first operation mode M1 and the second operation mode M2. For the description of the heterogeneous pressure energy interaction actuation module 10 executing the first operation mode M1 and the second operation mode M1, please refer to FIG. 2(a) and FIG. 2(b) together. FIG. 2(a) is a diagram illustrating the present invention. Figure 1 FIG. 2( b) is a schematic diagram of the operation of the heterogeneous pressure energy interaction actuation module of the first embodiment of the present invention in the first operation mode; and FIG. Figure 1 FIG. 4 is a schematic diagram of the operation of the heterogeneous pressure energy interaction actuation module of the first embodiment executing the second operation mode.

[0046] When executing the first operation mode M1, the heterogeneous pressure energy interaction actuation module 10 receives the working liquid WL, and when executing the second operation mode M2, the heterogeneous pressure energy interaction actuation module 10 connects to a converter (not shown) to push the working liquid WL to the converter 4, for example, the converter can be a liquid pump, a turbine pump, a liquid generator, a liquid turbine generator, a water turbine generator, etc. Generally speaking, the first operation mode M1 and the second operation module are operated in different time periods, for example, the first operation mode M1 is executed during the low power consumption period and the second operation mode M2 ​​is executed during the peak power consumption period. In addition, in other embodiments, for example, when there are multiple heterogeneous pressure energy interaction actuation modules, it is possible that the first operation mode M1 and the second operation module M2 can be executed simultaneously at the same time.

[0047] In FIG. 2( a ), the first operation mode M1 means that when the first operation mode M1 is executed, the working liquid WL is injected into the heterogeneous pressure energy interaction actuation module 10. In addition, the working liquid WL can come from a liquid source, such as a water tank, a reservoir, a water tower, etc., which can provide a device or equipment for storing the working liquid WL. In FIG. 2( a ), the arrows represent the flow path of the working liquid WL.

[0048] In Figure 2(b), the second operating mode M2 ​​means that when the second operating mode M2 ​​is executed, the working fluid WL is discharged from the heterogeneous pressure energy interaction actuation module 10, so that when the heterogeneous pressure energy interaction actuation module 10 is connected to, for example, a converter, the working fluid WL can be discharged to the converter to drive the converter to operate.

[0049] It is worth noting that the aforementioned working liquid WL is water as one of the embodiments of the present invention. Other movable fluids or liquids are also within the scope of the embodiments of the present invention, such as organic solvents, inorganic solvents, molten salts, fluid ion salts, supercritical fluids, and various gases or other flowable substances or substances and mechanisms that can generate pressure.

[0050] Back to Figure 1 , the heterogeneous pressure energy interactive actuation module 10 includes a first container 12 and a second container 14. Among them, the names of the first container 12 and the second container 14 are containers, but the term container is not limited to a specific shape, etc. As long as it can be used to accommodate liquids, gases or solids and can bear the pressure generated at the same time, it belongs to the category of the first container 12 and the second container 14 in this embodiment. In addition, the material and thickness of the first container 12 and the second container 14 can also determine the pressure, the liquid used, the gas used or the solid used. For example, the material can be stainless steel, iron and other materials. In addition, it is worth noting that when the heterogeneous pressure energy interactive actuation module 10 is set underground or is sealed by other materials (such as cement, concrete, etc.). For example, when the first container 12 and the second container 14 are encapsulated by cement, the first container 12 and the second container 14 can enhance the pressure tolerance strength.

[0051] The first container 12 forms a first accommodating space SP1 to store the initial gas IG. Here, the first container 12 is described by taking a cylindrical tank as an example. In other embodiments, the first container 12 may also be a polygonal tank, a honeycomb tank or other shapes.

[0052] It is worth noting that the aforementioned initial gas IG uses air as one of the embodiments of the present invention, and other movable fluids or gases are also within the scope of the embodiments of the present invention, such as single hydrogen, helium, nitrogen or mixed gases (such as 20% hydrogen and 80% helium), etc., as well as various gases or other flowable substances or substances and mechanisms that can generate pressure. In addition, the initial gas IG can also be transformed from other material states, such as the gas state is transformed from the solid state or the liquid state, and the aforementioned transformation can occur through changes in temperature, pressure, etc. It is worth noting that in other embodiments, the initial gas IG can not only stay in the first accommodating space SP1, but also appear in the second accommodating space SP2. In addition, in addition to filling the entire first accommodating space SP1, the initial gas IG can also only fill part of the first accommodating space SP1.

[0053] The second container 14 is disposed on one side of the first container 12. Here, the second container 14 is described by taking the lower side of the first container 12 as an example. In other embodiments, the second container 14 can be disposed on any side of the first container 12, that is, it is not limited to being disposed on the lower side. The second container 14 forms a second accommodation space SP2 to store the initial liquid IL. After the second container 14 is connected to the first container 12, the second accommodation space SP2 is connected to the first accommodation space SP1. Here, the second container 12 is also described by taking a cylindrical tank as an example, and its description can refer to the description of the first container 12, which is not repeated here. Furthermore, the shape of the second container 12 can be the same as or different from the shape of the first container 12. It is worth noting that in other embodiments, the initial liquid IL can not only stay in the second accommodation space SP2, but also appear in the first accommodation space SP1. In addition, in addition to filling the entire second accommodation space SP2, the initial liquid IL can also only fill part of the second accommodation space SP2.

[0054] It is worth noting that the aforementioned initial liquid IL uses water as one of the embodiments of the present invention, and other movable fluids or liquids are also within the scope of the embodiments of the present invention, such as organic solvents, inorganic solvents, molten salts, fluid ion salts, supercritical fluids, and various gases or other flowable substances or substances and mechanisms that can generate pressure. Furthermore, the substance used in the initial liquid IL can be the same as or different from the substance of the working liquid WL. In addition, the initial liquid IL can also be transformed from other material states, such as a liquid state is transformed from a solid state or a gaseous state, and the aforementioned transformation can occur through changes such as temperature and pressure.

[0055] Continuing with the description of FIG. 2( a ), when the first operation mode M1 is executed, the working liquid WL is continuously injected into the second accommodating space SP2, so that the injected working liquid WL gradually increases the space occupied by the second accommodating space SP2 by gradually increasing the volume in the second accommodating space SP2, thereby driving the initial liquid IL to continuously compress the initial gas IG in the first accommodating space SP1, until the initial gas IG acts on the first accommodating space SP1 with a predetermined pressure, thereby allowing the first container 12 to reach and store the first pressure energy FPE. Since the distance between the molecules of the initial gas IG is squeezed and becomes smaller due to the push from the initial liquid IL, the initial gas IG is compressed to achieve the effect of energy storage. Among them, the numerical value of the predetermined pressure can range from several thousand Pascals to several MPa. For example, the numerical value of the predetermined pressure can range from 4 MPa (Mpa) (or N / m2) to 12 MPa. It is worth noting that as long as the initial liquid IL thrust continues to occur, the initial gas IG will also be continuously compressed until the initial liquid IL no longer pushes the initial gas IG due to pressure balance or the initial gas IG can no longer be compressed, and the initial gas IG will stop being compressed. In addition, the pressure of the initial gas IG can be adjusted to reach or maintain a predetermined pressure by adjusting the initial liquid IL to push the initial gas IG, thereby determining the amount of the first pressure energy FPE.

[0056] Continuing with the aforementioned Figure 2(b), when the second operating mode is executed, the working liquid WL is discharged from the second accommodating space SP2 in the opposite direction. At this time, the initial liquid IL is pushed by the first pressure energy FPE, which causes the working liquid WL to be pushed in the direction of, for example, a converter. This is due to the pressure release caused by the continuous expansion of the compressed initial gas IG, that is, the initial gas IG drives the initial liquid IL to discharge, so as to convert the first pressure energy FPE into a second pressure energy SPE to drive the converter, and the converter 4 is acted upon by the second pressure energy SPE to generate electrical energy E (or electricity).

[0057] In an experimental simulation embodiment, a heterogeneous pressure energy interactive actuation module can generate electricity ranging from 30 kilowatts to 300 kilowatts (kW) through the action of a first container and a second container tank (or capsule) whose pressure is maintained between several MPa and tens of MPa. Taking the example that the heterogeneous pressure energy interactive actuation module can provide 300 kilowatts, when 2,500 heterogeneous pressure energy interactive actuation modules are used, approximately 750,000 kilowatts of electricity can be generated.

[0058] In another embodiment, the first container 12 and the second container 14 can be a separate container (not shown) having a storage space (not shown). For ease of understanding, the space for storing the initial gas IG in the container is defined as the first storage space SP1 and the space for storing the initial liquid IL in the container is defined as the second storage space SP2. In other words, the capacity size of the storage space is the sum of the capacity size of the first storage space SP1 and the capacity size of the second storage space SP2. Therefore, when executing the first operation mode M1 and the second operation mode M2 ​​mentioned above, as the capacity (or volume) of the initial gas IG changes, the capacity size of the first storage space SP1 will also change, and as the capacity (or volume) of the initial liquid IL changes, the capacity size of the second storage space SP2 will also change. In this embodiment, the principle of actuation can refer to the description of the first embodiment, and will not be repeated here.

[0059] Please refer to Figure 3 , is a three-dimensional schematic diagram of a heterogeneous pressure energy interactive actuation module according to a second embodiment of the present invention. Figure 3 In, with Figure 1 The difference is that the heterogeneous pressure energy interaction actuation module 10' includes a first tube 16 and a second tube 18 in addition to the first container 12 and the second container 14 mentioned in the first embodiment. The configuration of the first tube 16 and the second tube 18 makes the configuration of the first container 12 and the second container 14 more flexible.

[0060] The description of the first container 12 and the second container 14 may refer to the description of the first embodiment, and will not be repeated here.

[0061] exist Figure 3 In the embodiment, the first tube 16 provides a first end 162 and a first third end 164. The first end 162 is coupled to the first container 12 and the first third end 164 is coupled to the second container 14, so that the first tube 16 communicates with the first accommodation space SP1 and the second accommodation space SP2.

[0062] The second tube 18 provides a second second end 182 and a second fourth end 184. The second second end 182 is coupled to the second container 14 and the second fourth end 184 to connect the converter 4 shown in FIG. 4( b) and the liquid source 2 shown in FIG. 4( a). Here, the diameter of the second tube 14 is larger than the diameter of the first tube 12. In another embodiment, the diameter of the second tube 14 can also be equal to the diameter of the first tube 12. Under the condition that the diameter of the second tube 14 is larger than the diameter of the first tube 12, the initial liquid IL can pass through the first tube 16 to accelerate the speed of compressing the initial gas IG.

[0063] For the description of the heterogeneous pressure energy interaction actuation module 10' executing the first operation mode M1 and the second operation mode M2, please refer to FIG. 4(a) and FIG. 4(b). Figure 3 FIG. 4( b) is a schematic diagram of the operation of the heterogeneous pressure energy interaction actuation module of the second embodiment of the present invention in the first operation mode; and FIG. Figure 3 An operation diagram of the heterogeneous pressure energy interaction actuation module of the second embodiment executing the second operation mode.

[0064] According to the technical features of the first tube body 16 and the second tube body 18 added in this embodiment, the first operation mode M1 and the second operation mode M2 ​​can be adjusted as follows with reference to the description of FIG. 2( a ) and FIG. 2( b ) above:

[0065] When the first operation mode M1 is executed, the working liquid WL from the liquid source 2 is continuously injected into the second accommodation space SP2 through the second tube 18, so that the working liquid WL drives the initial liquid IL to continuously compress the initial gas IG in the first accommodation space SP1 through the first tube 16, until the initial gas IG acts on the first accommodation space SP1 to have a predetermined pressure, thereby allowing the first container 12 to store the first pressure energy FPE. Since the distance between the molecules of the initial gas IG is squeezed and becomes smaller due to the pushing of the initial liquid IL, the initial gas IG is compressed to achieve the effect of energy storage.

[0066] When the second operating mode is executed, the working liquid WL is no longer continuously injected into the second accommodating space SP2 through the second tube body 18, but is discharged from the second tube body 18 in the opposite direction. At this time, the compressed initial gas IG continues to expand and causes the initial liquid IL to be pushed by the first pressure energy FPE, which causes the working liquid WL to be pushed toward the direction of the converter 4, that is, the initial gas IG drives the initial liquid IL to discharge toward the second fourth end 184 of the second tube body 18, so as to convert the first pressure energy FPE into a second pressure energy SPE to drive the converter 4, and the converter 4 is acted upon by the second pressure energy SPE to generate electric energy E (or electricity).

[0067] Please refer to Figure 5 , is a three-dimensional schematic diagram of a heterogeneous pressure energy interactive actuation module according to the third embodiment of the present invention. Figure 5 In the embodiment, the heterogeneous pressure energy interactive actuation module 10 ″ includes not only the first container 12 , the second container 14 , the first tube 16 and the second tube 18 of the second embodiment, but also a third tube 28 , a hole cover 29 and a maintenance pipe 30 .

[0068] The description of the first container 12 , the second container 14 , the first tube 16 and the second tube 18 are the same as those of the second embodiment and are not repeated here.

[0069] The third tube 28 is disposed in the first container 12. One end of the third tube 28 is coupled to the first accommodating space SP1 and the other end of the third tube 28 is used to receive external gas EG to supplement the initial gas IG.

[0078] One end of the second tube 18 is coupled to the second container 14 and the other end of the second tube 18 is coupled to the first pipe 6. The diameter of the second tube 18 can be larger or smaller than the diameter of the first tube 16.

[0079] The liquid source 2 supplies and recovers the working liquid WL. For example, the liquid source 2 may be a water tank, a water tower, a reservoir, etc. The supply function of the liquid source 2 may refer to the description of the first embodiment, and will not be repeated here. Here, in addition to the supply function, the liquid source 2 may also recover the working liquid WL output from the converter 4 through the second pipe 8.

[0080] The converter 4 receives and outputs the working liquid WL.

[0083] When the first operating mode M1 is executed, the working liquid WL from the liquid source 2 is injected into the second storage space SP2 via the first pipe 6 and the second tube body 18, so that the working liquid WL drives the initial liquid IL to continuously compress the initial gas IG in the first storage space SP through the first tube body 16 until the initial gas IG acts on the first storage space SP1 with a predetermined pressure, thereby allowing the first container 12 to store the first pressure energy FPE.

[0084] When the second operating mode M2 ​​is executed, the initial gas IG continues to expand to drive the initial liquid IL to discharge toward the second tube body 18, so as to convert the first pressure energy FPE into the second pressure energy SPE and drive the converter 4 to generate electrical energy E through the first pipeline 6. After driving the converter 4, the working liquid WL returns to the liquid source 2 through the second pipeline 8.

[0085] Please refer to Figure 7 , Figure 7 1 is a three-dimensional schematic diagram of a heterogeneous pressure energy interactive actuation energy storage system according to the fifth embodiment of the present invention.

Compared with the aforementioned fourth embodiment, the pump 34 in this embodiment can make the heterogeneous pressure energy interactive actuation energy storage system have a better energy storage effect and store and release more energy.

[0086] The description of the heterogeneous pressure energy interactive actuation module 10 ″, the liquid source 2 , the converter 4 , the first pipeline 6 and the second pipeline 8 are the same as those of the third embodiment, and will not be repeated here.

[0087] The pressure sensor 32 can be used to sense changes in, for example, the working liquid WL, the initial liquid IL, or the initial gas IG and generate a corresponding sensing signal SS. Here, the pressure sensor 32 is described by taking the first container 12 as an example. In other embodiments, the pressure sensor 32 can also be disposed in at least one of the second container 14, the first tube 16, the second tube 18, the first pipe 6, and the second pipe 8.

[0088] The pump 34 can be used to adjust the flow rate of, for example, the working liquid WL or the initial liquid IL. The pump 34 here can be specially designed to provide the working liquid WL with a very large flow rate and pressure to act on the initial liquid IL and the initial gas IG, so that energy can be quickly and easily stored in the first container 12 and the second container 14. Here, the pump 34 is described by taking the example of being arranged between the first pipe 6 and the liquid source 2. In other embodiments, the pump 34 can also be arranged in at least one of the first accommodating space SP1, the second accommodating space SP2, the first tube 16, the second tube 18, the first tube 16 and the first container 12, the second tube 18 and the second container 14, the first pipe 6, the second pipe 8, the second pipe 8 and the liquid source 2, and the second pipe 8 and the converter 2. In addition, the pump 34 adjusts the working liquid WL of the liquid source 2 to enter the heterogeneous pressure energy interactive actuation module 10".

[0089] The valve bodies 36, 36' can provide an open mode and a closed mode manually or automatically. The automatic mode can be controlled by a control signal CS, and the control signal CS can be generated by a controller 38. In addition, in the open mode, the working liquid WL, the initial liquid IL and the initial gas IG can pass through the valve body, and in the closed mode, the working liquid WL, the initial liquid IL and the initial gas IG are blocked by the valve body. Here, the valve body 36 is described by taking the first pipe 6 and the liquid source 2 and the valve body 36' is described by taking the first pipe 6 and the converter 4 as an example. In other embodiments, the valve body can also be set at least one of the first container 12, the second container 14, the first tube 16, the second tube 18, the first tube 16 and the first container 12, the second tube 18 and the second container 14, the first pipe 6, the second pipe 8, the second pipe 8 and the liquid source 2, and the second pipe 8 and the converter 4.

[0090] The controller 38 can receive the pressure generated by the pressure sensor 32 to sense, for example, the working liquid WL, the initial liquid IL, or the initial gas IG to generate a sensing signal SS. The controller 38 generates a control signal CS according to the sensing signal SS to operate the valve body 36, 36' to further perform the opening mode or the closing mode. In detail, the controller 38 outputs the control signal CS to operate the valve body 36 to control the initial gas IG to a predetermined pressure, and when the initial gas IG has the predetermined pressure, the initial gas IG stops being compressed.

For example, the controller 38 controls the valve body 36 to allow the four heterogeneous pressure energy interactive actuation modules 102, 104, 106, 108 to store about four times the first pressure energy FPE at the same time, or to allow the four heterogeneous pressure energy interactive actuation modules 102, 104, 106, 108 to release about four times the second pressure energy SPE at the same time.

[0092] In another embodiment, the controller 38 can also execute the control program APP to allow the heterogeneous pressure energy interactive actuation modules 102, 104, 106, 108 to store the first pressure energy FPE or convert the second pressure energy SPE asynchronously. For example, the controller 38 controls the valve body 36 to allow any heterogeneous pressure energy interactive actuation module 102, 104, 106, 108 to independently store or release energy. In other words, the controller 38 can select a single, multiple or all heterogeneous pressure energy interactive actuation modules to drive the converter to generate one or more times of electrical energy or extend the time for generating electrical energy E.
