Abstract

A geothermal energy storage/converting system utilizes hot water and pressure, such as steam, generated by the geothermal heat/ground water to store energy and/or generate electricity. The system utilizes a motion of a piston, driven by steam generated by geothermal heat, to control movement of an amount of water, which is used to store the energy by compressing gas as energy storage. When electricity is needed, the compressed gas provides a force to push the stored water to drive a hydrogenerator to generate electricity. In a geothermal energy converting embodiment, system utilizes a motion of a piston, driven by steam generated by geothermal heat, to control movement of an amount of water to drive a hydrogenerator to generate electricity.

Although the present disclosure relates to geothermal energy/geothermal heat, the present invention also encompasses the use of waste heat as a heat source for energy storage. Geothermal heat is one of various types of waste heat that occurs naturally in the environment.

Figure 1 illustrates a structural diagram of a generator and/or energy storage device according to some embodiments of the present invention. The generator and energy storage can be driven/powered by geothermal and thermal groundwater/steam. As shown in Figure 1, the geothermal feedback energy storage system includes a water inlet unit 1, a controller 2, a piston 12, a first air inlet 3, a second air inlet 4, and a first water pipe 5 (as one of the first fluid pipes). example), the energy storage cabin 6, the generator 7, the storage tank 8 (as an example of the fluid storage tank), the second water pipe 9 (as an example of the second fluid pipe), or a plurality of valves 10, 13, 14, 15 and 16. The third air inlet hole 11-1, the fourth air inlet hole 11-2, and another water storage tank 17 (as an example of another water storage tank).

In this system, groundwater enters the water inlet unit 1 from the groundwater source. The groundwater is heated by geothermal energy to form hot water with a predetermined pressure range. The temperature range of this groundwater is 120 degrees Celsius to 180 degrees Celsius (℃), and the pressure range is 4 kg/cm ² to 10 kg/cm ² . For example, when the groundwater is located 1,000 meters below the ground, its temperature can reach 180 degrees Celsius (℃) and its pressure can reach about 10 kg.

In the water inlet unit 1, the water inlet unit 1 can use a pump to extract a certain amount of groundwater, and enter the water inlet unit 1 through a water pump or other structures/methods. The water inlet unit 1 may be, for example, a storage tank, a container, or a container made of a specific material, such as a space surrounded by cement. After the water inlet unit 1 is injected with groundwater, the groundwater becomes hot water (such as steam) with pressure. For example, the water inlet unit 1 has groundwater with a temperature of 150 to 180 degrees Celsius (℃). The pressure value is between 6 kg/cm ² and 10 kg/cm ² . In the water inlet unit 1, pressure changes are used to convert liquid into gas. For example, the state of a gas can be converted into water vapor with a temperature of 150 degrees Celsius (°C) and a pressure of 6 kg/ ^cm2 .

Taking Figure 1 as an example, when the gas is guided/controlled by the controller 2, the gas enters the first air inlet 3 and the internal space of the piston 12 to drive the piston 12 (such as through gas pressure) as shown in Figure 1. As shown in Figure 1, it moves downward, thus forming a thrust, and then pushes (or squeezes) the material in the first water pipe 5. The substance in the first water pipe 5 (for example, it is a fluid, which may be a liquid, a solid, a gas, or a combination of any of the foregoing items) moves toward the energy storage cabin 6 . The gas (or steam) formed in the water inlet unit 1 can be guided by the controller 2 to guide the gas to the first air inlet 3 and the second air inlet 4 to drive the movement of the piston 12 .

In this embodiment, the piston 12 is further provided with a first air inlet hole 3 and a second air inlet hole 4 . The first air inlet hole 3 and the second air inlet hole 4 can be used as an injection port or a discharge port. The piston 12 is connected to the first water pipe 5 and the second water pipe 9 . In addition, in the above model, valves can be provided on both the first water pipe 5 and the second water pipe 9 . A valve 10 (such as a one-way valve) is provided at one end of the second water pipe 9 so that when the piston 12 (such as in push mode) is pressed toward the second air inlet 4, the valve 10 will prevent liquid from passing through the valve 10 . On the other hand, when the piston 12 is pulled towards the first water inlet hole 3 (as in extraction mode), liquid is allowed to pass through the valve 10 (as in moving upwards).

Therefore, in the pushing mode (such as energy storage), the liquid in the first water pipe 5 is pushed into the energy storage cabin 6; therefore, the gas volume in the energy storage cabin 6 is reduced, thereby compressing the gas (For example in operating mode, valves 13 and 15 are open and valve 14 is closed). In this embodiment, the gas may be insoluble or partially soluble in the liquid during compression. If the substance (such as liquid or gas) in the first water pipe 5 has no other leakage path except the energy storage tank 6, the gas in the energy storage tank 6 will continue to be compressed. The piston 12 can control the flow of material in the first water pipe 5 and the amount of material (such as liquid) entering the energy storage cabin 6 . The piston 12 is controlled by the controller 2 and water vapor.

In the energy release/generation mode, the air pressure in the energy storage chamber 6 will push the material out of the energy storage chamber 6, so that the material located in the first water pipe 5 moves to the generator 7, thereby The substance (liquid or gas) acts on the generator 7 to generate electricity (for example, in operation mode, the piston remains pushed and valves 13, 14 and 15 are open). For example, when the substance is a liquid, the generator 7 can be a water turbine generator, a turbine, a water turbine or a water turbine, and the liquid pushes/drives the water turbine generator to rotate to generate electricity.

In some embodiments, the movement path of the substance in the first water pipe 5 can be controlled by a valve. For example, the valve can allow the material in the first water pipe 5 to enter the energy storage chamber 6 to compress the gas, so that the gas pressure increases due to the reduction of air space (such as space displacement).

In some embodiments, when the substance is in a gaseous form, the generator 7 may be an air/gas turbine generator, and the gas propels/drives the gas turbine generator to rotate to generate electricity.

Then, after operating/closing the valve 13 (opening valves 15 and 14), the material in the first water pipe 5 moves towards the generator 7 because the material located in the energy storage chamber 6 pushes the material located in the first The material in the water pipe 5 forms a strong thrust to push the generator 7 until the material in the energy storage chamber 6 is exhausted (for example, reduced to a predetermined gas pressure or water level), or until the material cannot effectively drive the generator 7 until the generator 7 generates a predetermined rate/amount of electricity. The substances acting on the generator 7 will be collected into the storage tank 8 .

In some embodiments, the valves and all other control components of the system are controlled by a computer or remote (such as wireless network) control system, including control systems utilizing AI artificial intelligence.

Now let’s talk about pulling mode. In the pulling mode of the piston 12 , the substance stored in the water storage tank 8 will return to the valve 10 via the second water pipe 9 again.

After the material in the energy storage cabin 6 no longer acts on the generator 7 or after the material in the energy storage cabin 6 has been consumed, the aforementioned controller 2 introduces the gas into the second air inlet 4 of the piston 12 , as shown in Figure 1, to return the system to the initial startup state. For example, after the controller 2 guides the gas, the gas enters the inner space of the second air inlet 4 and the piston 12, driving the piston 12 in Figure 1 to move upward (such as through gas pressure) to form a stream of gas. Tensile force, thereby pulling the substance (such as liquid, solid, gas or any combination of the above items) from the second water pipe 9 to the direction of the first water pipe 5 and the energy storage cabin 6, thereby completing the storage of the water cycle. It can reach the power generation process.

In the above process, it can be understood that the groundwater provided by the geothermal energy that already exists in the natural environment can be used for water circulation energy storage and power generation through the operation of continuously generated water vapor (such as repeatedly pushing/pulling the piston 12). system.

In addition, after the gas (or water vapor, steam) acts on the first air inlet hole 3 and the second air inlet hole 4 of the piston 12, the gas can pass through the third air inlet hole 11-1 and the second air inlet hole 4 of the controller 2. The fourth air inlet 11-2 enters another water storage tank 17 for cooling. After cooling, the water temperature of the water vapor drops to, for example, about 60 degrees Celsius (℃), and is further discharged to the bottom of the surface layer. This can avoid land collapse or depression, and can also continue to generate hot groundwater through geothermal heat.

Figure 2 illustrates an energy storage mode 200 according to some embodiments of the invention.

When the gas is guided/controlled by the controller 2, the gas enters the first air inlet 3 to drive the piston 12 to move downward as shown in Figure 1 to form thrust, and then pushes (or squeezes) the first water pipe 5 substances. The substance in the first water pipe 5 (for example, it is a fluid, which can be, for example, a liquid, a solid, a gas, or a combination of any of the foregoing items) moves toward the energy storage cabin 6 . The reduction of the space in the energy storage cabin 6 causes the gas pressure inside the energy storage 6 to increase (for example, from 1 atm to 50-110 atm). This achieves energy storage. In this embodiment, the energy storage cabin 6 is provided with a valve 15 , which is located near the connection of the energy storage cabin 6 to determine the entry/exit of fluid or the storage/release of energy. For example, when power demand is low, the valve 15 is closed so that the compressed gas in the energy storage tank cannot expand or push out liquid to store energy (such as pressure energy). During periods of high power demand, this valve 15 opens, allowing the compressed gas to expand back to its original lower pressure state (i.e., back to the initial or original pressure), thereby moving the liquid to drive the turbine to generate electricity.

This embodiment uses a piston as the actuating unit. Any type of force can be used to trigger the piston to move up and down. In some embodiments a machine is used to trigger the push and pull of the piston.

In some embodiments, the actuating unit and the energy storage cabin are coplanar, such that the actuating unit and the energy storage cabin are disposed on the same horizontal plane. In some embodiments, the actuating unit, fluid pipe and energy storage chamber are disposed on the same horizontal plane. In this way, the energy storage system (or power generation system) is not limited by terrain conditions.

Figure 3 illustrates an energy release/generation pattern 300 according to some embodiments of the present invention.

After operating/closing valve 13 (while keeping valves 14 and 15 open), the contents of the first water pipe 5 move towards the generator 7 because the gas pressure in the energy storage chamber 6 pushes the gas located in the first water pipe The material in 5 forms a strong thrust to push the generator 7 until the material in the energy storage chamber 6 is exhausted (for example, reduced to a predetermined level), or until the material cannot effectively drive the generator 7 to produce a predetermined speed. /amount of electricity. The substance in the first water pipe 5 may be gas, liquid, solid, slurry or a combination of the aforementioned items. In this embodiment, the substance located in the first water pipe 5 is water. As shown in Figure 3, the generator is connected to a water storage tank 8, which serves as an example of a fluid storage tank. The fluid storage tank recovers the material (such as water) that acts on the generator. The fluid storage tank may be a natural facility. For example, natural facilities can be rivers, lakes, etc.

Figure 4 illustrates an energy release/generation pattern 400 in accordance with some embodiments of the present invention.

In Figure 4, pattern 400 shows a plurality of energy storage units relative to a hydrogenerator (many to one). The energy storage unit may include: an actuating unit, a first water pipe 5 (as a first fluid pipe), an energy storage chamber 6, and a second water pipe 9 (as an example of a second fluid pipe). The energy storage/power generation system shown in Figure 4 includes: two water inlet units, two storage tanks, and two control units, but it is also possible to use only one water inlet unit, one storage tank, and one control unit. For example, in Figure 4, both actuation units can be connected to the same control unit, thereby omitting the other control unit. The system may include one or more energy storage units. In this embodiment, the system includes two energy storage units. The number of energy storage units and their associated hydrogenerators can be adjusted according to user needs.

In Figure 4, the piston 12 can be replaced by a heavy object (for example, a stone with a certain weight). The weight can vary from 40kg to 60kg. The weight of the weight can be adjusted as needed, for example, it can be between 1 kilogram and 100 tons. When a heavy object is used as the actuating unit, the weight is dropped from a higher position to generate thrust. In some embodiments, the drop of the weight may be triggered by a machine. With thrust, the energy storage/generation process in Figure 1 can be implemented as described above. The weight can be pushed back to its original (higher) position by mechanical force, and the energy storage and power generation process can be repeated.

Figure 5 illustrates a geothermal energy converter 500 according to some embodiments of the invention.

The geothermal energy converter 500 described below can be combined with the energy storage device shown in Figures 1 to 4 above, so that the system can simultaneously perform conversion and storage of geothermal energy. The geothermal energy converter 500 can be driven/powered by geothermal and hot groundwater/steam.

In Figure 5, the geothermal energy converter 500 includes: a first water inlet unit 501, a second water inlet unit 521, a first controller 502, a second controller 525, a first piston 512, a second piston 523, The first group of first air inlet holes 513, the second group of first air inlet holes 522, the first group of second air inlet holes 514, the second group of second air inlet holes 524, the first water pipe 505, the second water pipe 515, A first liquid storage container 506, a generator (eg, a hydroelectric generator), a second liquid storage container 509, one or more valves 516, 517, and 518, and water storage tanks 530 and 531.

The geothermal energy converter 500 may include a first operation unit 532 and a second operation unit 533 . The first operation unit 532 and the second operation unit 533 can jointly operate as an uninterrupted power generation system.

During operation, groundwater enters the water inlet unit 501 from a groundwater source. The groundwater is heated by geothermal energy to form hot water with a predetermined pressure range. The temperature range of this groundwater is 120 degrees Celsius to 180 degrees Celsius (℃), and the pressure range is 4 kg/cm ² to 10 kg/cm ² . For example, when the groundwater is located 1,000 meters below the ground, its temperature can reach 180 degrees Celsius (℃) and its pressure can reach about 10 kg.

In the water inlet unit 501, the water inlet unit 501 can use a pump to extract a certain amount of groundwater, which enters the water inlet unit 501 via a water pump or other structures/methods. The water inlet unit 501 may be, for example, a storage tank, a container, or a container made of a specific material, such as a space surrounded by cement. After the water inlet unit 501 injects groundwater, the groundwater becomes hot water (such as steam) with pressure. For example, the water inlet unit 1 has groundwater with a temperature of 150 to 180 degrees Celsius (°C). The pressure value is between 6 kg/cm ² and 10 kg/cm ² . In the water inlet unit 501, pressure changes are used to convert liquid into gas. For example, the state of a gas can be converted into water vapor with a temperature of 150 degrees Celsius (°C) and a pressure of 6 kg/ ^cm2 .

In the example of Figure 5, when the gas is guided/controlled by the controller 502, the gas enters the first air inlet 513 and the internal space of the piston 512 to drive the piston 512 (such as via gas pressure) as As shown in Figure 5, it moves downward, thus forming a thrust force, and then pushes (or squeezes) the liquid (such as water) in the first water pipe 505. The substance in the first water pipe 505 (for example, it is a fluid, which may be a liquid, a solid, a gas, or a combination of any of the foregoing items, etc.) moves toward the first liquid storage container 506 . The gas (or steam) formed in the water inlet unit 501 can be guided by the controller 502 to guide the gas to the first group of first air inlet holes 513 and the first group of second air inlet holes 514. The movement of the piston 512 is driven.

In this embodiment, the piston 512 is also provided with a first group of first air inlet holes 513 and a first group of second air inlet holes 514 . The first air inlet hole 513 and the second air inlet hole 514 can be used as an injection port or a discharge port. The piston 512 is connected to the first water pipe 505 .

Valves 516, 517, and 518 control the flow of a fluid stream.

Therefore, in the power generation mode of the first operating unit 532, the liquid in the first water pipe 505 is pushed toward the first liquid storage container 506 by the reduced space occupied by the piston 512. Since the first liquid storage container 506 is filled with liquid, additional liquid entering is pushed toward the hydrogenerator 507 to generate electricity. The liquid system passing through the hydroelectric generator 507 is stored in the second liquid storage container 509 . When the additional liquid (the volume of liquid moved by the space reduction of the piston) from the first operating unit 532 is consumed or exhausted, the second operating unit 533 begins to move the second piston 523 to the push mode, It is similar to the operation mode of the first operating unit 532 mentioned above. Therefore, the first operating unit 532 and the second operating unit 533 operate in turn to form an uninterrupted and continuous geothermal energy converter to convert geothermal energy or any other type of thermal energy/pressure into electrical energy.

In the receiving mode, the piston 512 moves upward by passing steam through the first set of second air inlet holes 514, causing the first piston to move upward (as in the extraction mode), thereby returning the fluid to the first operating unit 532. The operation of the receiving mode of the second operating unit 533 is similar to the receiving mode of the first operating unit 532 .

In some embodiments, the first operating unit 532 may be constructed as a stand-alone unit (eg, without the second operating unit 533 ) by providing a return unit 550 controlled by a valve 518 . In this configuration, valve 517 (eg in the closed state) may be the stopping point/dividing point to achieve the independent unit described above.

After the gas (or water vapor, steam) acts on the first group of first air inlet holes 513 and the first group of second air inlet holes 514 of the first piston 512 of the first operating unit 532, the gas can pass through the first group of first air inlet holes 513 and the first group of second air inlet holes 514. The first set of third air inlets 519 and the first set of fourth air inlets 520 of a controller 512 enter another water storage tank 530 for cooling. Similarly, after the gas (or water vapor, steam) acts on the second group of first air inlet holes 522 and the second group of second air inlet holes 524 of the second piston 523 of the second operating unit 533, the gas can Through the second set of third air inlet holes 526 and the second set of fourth air inlet holes 527 of the second controller 525, it enters another water storage tank 531 for cooling. After cooling, the water temperature of the water vapor drops to, for example, about 60 degrees Celsius (℃), and is further discharged to the bottom of the surface layer. This can avoid land collapse or depression, and can also continue to generate hot groundwater through geothermal heat.

Figure 6 illustrates a flow chart of an energy storage and generation cycle process according to some embodiments of the present invention.

In step S1, thrust is generated. The thrust can be controlled by an actuating unit (such as a piston) and generated by steam (through geothermal heat) or heavy objects.

In step S2, the first substance (such as water) located in the flow path uses the thrust to compress the second substance (such as air or gas), so that energy is stored in the second substance. Each of the first substance and the second substance can be a gas, liquid, solid or a combination thereof. In some embodiments, the first substance is a fluid. The fluid may be water. In some embodiments, the second substance is a compressible substance (such as a gas). The gas can be an inert gas (such as helium), nitrogen, or a mixture of different types of gases. In Figure 1, the force causes the substance (first substance) located in the first water pipe 5 to compress the substance (second substance) located in the energy storage chamber 6. The compressed material stores energy (pressure energy) as its volume decreases and pressure increases. Therefore, steps S1 and S2 can be regarded as energy storage processes. Since the compressed material has a high pressure (such as a pressure between 40 and 60 atm or between 1 and 200 atm), the energy storage cabin 6 can be made of pressure-resistant material.

In step S3, the compressed second material will expand to push the first material out of the energy storage cabin 6, thereby causing the first material to flow to the generator to generate electricity. The generator may be a water turbine generator, a turbine, a water turbine or a water turbine. Therefore, step S3 can be regarded as an energy generation/release process. During the energy transfer process, energy may be lost in the form of waste heat. Therefore, the energy release/generation system may further comprise a heat recovery unit. The heat recovery unit can connect the first fluid pipe and the water inlet unit, so that the groundwater in the water inlet unit can be heated by waste heat.

In step S4, the first substance transferring energy to the generator is recovered. Specifically, after the first substance completes energy transfer, it will be collected into, for example, a storage tank.

In step S5, the recovered first substance is guided to the flow path by pulling force. The guided first substance will be used for the next round of energy storage/power generation, thereby completing the energy storage and power generation process of fluid (such as water) circulation. The pulling force may be generated by the actuating unit used to generate thrust force in step S1. Steps S1 to S5 can be repeated to form a complete energy storage and regeneration cycle.
