Description

[Technical field]

[0001] The present invention relates to a CO2 capture system. [Background technology]

[0002] It is widely known that carbon dioxide (CO2) concentrations show a strong correlation with global warming, which leads to rising atmospheric temperatures and increased chances of natural disasters such as typhoons and floods. Power plants, oil refineries, cement factories, steel production processes, and other industries emit large amounts of CO2 from their plants, and how to reduce these CO2 emissions has become a major issue.

[0003] As a method for reducing the amount of CO2 emissions, several technologies have been proposed for capturing CO2 in exhaust gas. Patent Document 1 discloses a calculation system that calculates the amount of CO2 captured based on the cost of capturing CO2 in exhaust gas and the trading price of CO2 emission rights in the CO2 emission rights market. Furthermore, Patent Document 2 discloses an operation control system for a CO2 capture device for power generation equipment that maximizes an evaluation index obtained by subtracting the expenditure price arising from the operation of the power generation equipment including a CO2 capture device from the income price arising from the operation of the power generation equipment including a CO2 capture device. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2010-169282 A [Patent Document 2] JP 2012-245430 A Summary of the Invention [Problem to be solved by the invention]

[0005] While CO2 emissions are a target for reduction, it also has many uses, such as carbon dioxide gas for producing carbonated drinks and bath salts, dry ice, shielding gas for arc welding, carbon dioxide lasers, etc. There are many users across the country who require CO2 for these uses.

[0006] CO2 as an industrial product is obtained by refining carbon dioxide, a by-product emitted from steel mills and oil refineries. Currently, there are only a few plants that produce CO2 in Japan, but there are many consumers across the country who need CO2, making it necessary to transport it long distances. CO2 may also be imported from abroad, but in this case too, it must be transported long distances.

[0007] At a time when there is a demand to reduce CO2 emissions, it is undesirable that CO2 needs to be transported long distances. Therefore, there is a demand to shorten the distance between the places where CO2 is supplied and the people who need it, so that long-distance transport of CO2 is not necessary.

[0008] The above-mentioned Patent Documents 1 and 2 describe the capture of CO2, but do not describe how to handle the captured CO2.

[0009] If small-scale CO2 emission sources could be used as CO2 supply sources, rather than large-scale CO2 production plants, and the CO2 emitted from those sources could be captured and supplied to CO2 consumers, there would be no need to transport CO2 long distances.

[0010] The present invention has been made against the background described above, and aims to provide a CO2 capture system that captures CO2 near consumers, without transporting the CO2 long distances, and allows the consumers to use the captured CO2. [Means for solving the problem]

[0011] In order to achieve the above object, the CO2 capture system of the present invention includes a CO2 generation means for generating CO2 using a small power generation device installed in a business premises, and a CO2 capture means for capturing the generated CO2, and the CO2 capture means performs a CO2 capture operation to capture CO2. a CO2 consumer terminal having an input unit into which CO2 demand information is input by a CO2 consumer, and a transmission unit that transmits the demand information input from the input unit; a demand information processing terminal having a receiving unit that receives the demand information transmitted from the transmitting unit of the CO2 consumer terminal, a calculation unit that calculates the amount of CO2 to be recovered by the CO2 capture mechanism based on the demand information received by the receiving unit, and a transmitting unit that transmits the CO2 capture amount information calculated by the calculation unit to the CO2 capture mechanism, The CO2 capture mechanism has a receiving unit that receives the CO2 capture amount information transmitted from the transmitting unit of the demand information processing terminal, and is characterized in that it performs CO2 capture operation based on the CO2 capture amount information received by the receiving unit.

[0012] In the CO2 capture system of the present invention, a small power generation device installed at a business establishment is used as a CO2 generation means. Since the small power generation device is a device installed at a business establishment located in the area where the CO2 capture system is installed, using the small power generation device as a CO2 generation means is synonymous with installing a CO2 generation means in each area. Each small power generating device installed at the business site has its own CO2 capture means. Therefore, the CO2 generated by the small power generating device is captured by the CO2 capture means. The captured CO2 can be made into a transportable form such as a cylinder, and by delivering this cylinder to a CO2 consumer in the same area, it is possible to connect (match) the CO2 supply source and the CO2 consumer without transporting the CO2 long distances.

[0013] It is preferable to generate and capture CO2 when the CO2 is needed by the consumer. Conversely, it is preferable not to generate and capture CO2 when the CO2 is not needed by the consumer. In light of this background, the process of linking CO2 demand with CO2 generation and CO2 capture is carried out by the demand information processing terminal.

[0014] A CO2 demand information is inputted into an input section of a CO2 demand terminal by a CO2 demander, and the demand information is transmitted to a demand information processing terminal. The demand information processing terminal has a calculation unit, which calculates the amount of CO2 to be captured by the CO2 capture mechanism based on the demand information, and transmits the calculated CO2 capture amount information to the CO2 capture mechanism. The CO2 capture mechanism performs CO2 capture operation based on the received CO2 capture amount information. In this way, optimal CO2 capture can be performed according to the CO2 demand information. That is, according to the CO2 capture system of the present invention, CO2 can be captured near consumers, and the consumers can use the captured CO2.

[0015] In the CO2 capture system of the present invention, the calculation unit further calculates a CO2 delivery route for delivering the CO2 captured by the CO2 capture mechanism to a CO2 consumer, It is preferable that the CO2 delivery route information calculated in the calculation unit is transmitted from the transmission unit of the demand information processing terminal to a deliverer terminal owned by a deliverer. In the calculation unit, in addition to calculating the amount of CO2 recovered, it is also possible to calculate the CO2 delivery route, making it possible to more efficiently connect CO2 supply sources and CO2 consumers. For example, when there are multiple CO2 consumers, the amount of CO2 emissions associated with delivery can be reduced by streamlining the CO2 delivery route.

[0016] In the CO2 capture system of the present invention, the demand information is preferably at least one piece of information selected from the group consisting of a CO2 delivery form, a required amount of CO2, a delivery location, a desired delivery time, and a desired purchase price. Depending on this demand information, the calculation unit can determine when, in what form, and how much CO2 will be captured. In addition, if the desired purchase price of CO2 is low and capturing CO2 is not profitable, a decision can be made not to capture CO2.

[0017] It is preferable that the CO2 capture system of the present invention further includes a CO2 storage mechanism for storing the CO2 captured by the CO2 capture mechanism. By storing the captured CO2 in a CO2 storage mechanism in the form of a cylinder or the like, if there is a sudden increase in demand for CO2, it is possible to respond to the increase in demand without wasting CO2 capture. Also, when calculating a CO2 delivery route, a CO2 storage mechanism may be added as a CO2 refill point on the delivery route.

[0018] In the CO2 capture system of the present invention, the CO2 storage mechanism includes a CO2 storage amount storage unit that stores the amount of CO2 stored in the CO2 storage mechanism, and a transmission unit that transmits CO2 storage amount information stored in the CO2 storage amount storage unit to the demand information processing terminal, It is preferable that the demand information processing terminal receives the CO2 storage amount information transmitted from the transmitter of the CO2 storage mechanism at the receiving unit, and the calculation unit further uses the received CO2 storage amount information to calculate the amount of CO2 to be recovered by the CO2 recovery mechanism.

[0019] When calculating the amount of CO2 captured, by using information on the amount of CO2 stored in addition to information on CO2 demand, the amount of CO2 captured by the CO2 capture mechanism can be calculated as a more optimal value. Assuming that there is a demand for the same amount of CO2, there may be cases where it is better not to capture CO2 when the amount of CO2 stored is large, and cases where it is better to capture CO2 when the amount of CO2 stored is small, so using information on the amount of CO2 stored is useful.

[0020] In the CO2 capture system of the present invention, the CO2 generating means is preferably a cogeneration system installed at a business establishment. In recent years, the number of companies installing cogeneration systems has increased due to growing environmental awareness. By using a cogeneration system as a means of generating CO2 and equipping it with a means of capturing CO2, the number of CO2 capture mechanisms can be increased.

[0021] In the CO2 capture system of the present invention, when the demand for CO2 is low or the price of CO2 is low, the calculation unit obtains CO2 capture amount information indicating that CO2 capture operation will not be performed as a result of calculation based on the demand information, and transmits the CO2 capture amount information from the transmission unit of the demand information processing terminal to the CO2 capture mechanism, It is preferable that the CO2 capture mechanism does not perform a CO2 capture operation.

[0022] Even if CO2 capture operation is performed and CO2 is captured, if there is no demand for the captured CO2 or capturing the CO2 is not profitable, the CO2 capture operation will not be performed. By doing so, it is possible to avoid operating the CO2 capture system in the red and to operate the CO2 capture system continuously in a profitable manner.

[0023] In the CO2 capture system of the present invention, the CO2 capture means is equipped with a CO2 capture structure in which a reaction layer that adsorbs and desorbs CO2 and a heating layer for heating the reaction layer are alternately stacked, and it is preferable that the reaction layer comprises a base, a support, and an adsorbent that adsorbs and desorbs CO2 supported on the support. In the CO2 capture means, reaction layers that adsorb and desorb CO2 and heating layers for heating the reaction layers are alternately stacked, and the reaction layers have a large contact area with the heating layers, so the reaction layers can be efficiently heated by the heating layers. In addition, since the heating layers are provided separately from the reaction layers that adsorb and desorb CO2, the heat source and the adsorbent in the reaction layers do not come into direct contact, and inexpensive water vapor can be used as the heat source for the heating layers, making it unnecessary to evaporate the water adsorbed in the reaction layers, and CO2 can be efficiently adsorbed and desorbed at low cost. In this specification, the term "adsorption / desorption" is used to mean not only "adsorption" and "desorption" but also "absorption" and "release." Also, an adsorbent is a substance that adsorbs and absorbs CO2 and desorbs and releases CO2 at a certain temperature.

[0024] In the CO2 capture system of the present invention, the range in which the CO2 capture system is operated is preferably a range that includes CO2 consumers within 50 km of one of the CO2 capture mechanisms. The CO2 capture system of the present invention makes it possible to create a cycle of CO2 capture and CO2 usage within a small area such as the above-mentioned range.

[0025] In the CO2 capture system of the present invention, the input unit is preferably an application provided to the CO2 consumer terminal. If CO2 consumers are allowed to input their own CO2 demand information on their own CO2 consumer terminals, it will be possible to connect (match) CO2 supply sources with CO2 consumers on the network.

[0026] In the CO2 capture system of the present invention, the calculation unit is provided with a trained artificial intelligence model that has learned the relationship between the weather conditions and the demand information based on training data that inputs weather conditions within the range in which the CO2 capture system is operated and outputs CO2 demand information, It is preferable that the calculation unit inputs weather conditions within the area in which the CO2 capture system is operated into the trained artificial intelligence model to estimate CO2 demand information, and calculates the amount of CO2 to be captured by the CO2 capture mechanism based on both the demand information input to the input means and received by the receiving unit and the demand information estimated by the artificial intelligence model.

[0027] Weather conditions are one of the factors that affect the demand for CO2. For example, when temperatures are high, the demand for carbon dioxide for carbonated drinks and dry ice for refrigeration increases, which is likely to lead to an increase in the demand for CO2. If the results of estimating CO2 demand information using an artificial intelligence model that has learned the relationship between factors that affect CO2 demand, such as weather conditions, and CO2 demand information are used to calculate the amount of CO2 captured by the CO2 capture mechanism, it is possible to predict increases in CO2 demand in advance and take measures such as increasing the amount of CO2 captured in advance. This makes it possible to create a CO2 capture system that can respond to increases and decreases in the demand for CO2.

[0028] In the CO2 capture system of the present invention, the calculation unit is provided with a trained artificial intelligence model that has learned a relationship between the past demand information from a specific CO2 consumer within the range in which the CO2 capture system is operated and the demand information received from the CO2 consumer based on training data that inputs a history of past demand information from the CO2 consumer and outputs the demand information received from the CO2 consumer, It is preferable that the calculation unit inputs a history of past demand information from the CO2 consumer into the trained artificial intelligence model to estimate CO2 demand information from the CO2 consumer, and calculates the amount of CO2 to be captured by the CO2 capture mechanism based on both the demand information input to the input means and received by the receiving unit and the demand information estimated by the artificial intelligence model.

[0029] If the results of estimating CO2 demand information using an AI model that has learned the relationship between the history of past demand information from CO2 consumers and CO2 demand information are used to calculate the amount of CO2 captured by the CO2 capture mechanism, it will be possible to predict increases in CO2 demand from the consumer in advance and take measures such as increasing the amount of CO2 captured in advance. This makes it possible to create a CO2 capture system that can respond to increases and decreases in CO2 demand. [Brief description of the drawings]

[0031] Detailed Description of the Invention [CO2 capture system] The CO2 capture system of the present invention includes a CO2 generation means for generating CO2 using a small power generation device installed at a business premises, and a CO2 capture means for capturing the generated CO2, and the CO2 capture means performs a CO2 capture operation to capture CO2. a CO2 consumer terminal having an input unit into which CO2 demand information is input by a CO2 consumer, and a transmission unit that transmits the demand information input from the input unit; a demand information processing terminal having a receiving unit that receives the demand information transmitted from the transmitting unit of the CO2 consumer terminal, a calculation unit that calculates the amount of CO2 to be recovered by the CO2 capture mechanism based on the demand information received by the receiving unit, and a transmitting unit that transmits the CO2 capture amount information calculated by the calculation unit to the CO2 capture mechanism, The CO2 capture mechanism has a receiving unit that receives the CO2 capture amount information transmitted from the transmitting unit of the demand information processing terminal, and is characterized in that it performs CO2 capture operation based on the CO2 capture amount information received by the receiving unit.

[0032] FIG. 1 is a block diagram showing a schematic example of the configuration of a CO2 capture system according to the present invention and the flow of information in the CO2 capture system. The arrows in Figure 1 indicate the direction of information flow between each element. FIG. 1 shows, as components of the CO2 capture system 1, a CO2 capture mechanism 10, a CO2 consumer terminal 20, a demand information processing terminal 30, a CO2 storage mechanism 40, and a deliverer terminal 50. Each of these components will be described below, along with the flow of information between the components.

[0033] [CO2 Capture Mechanism] The CO2 capture mechanism 10 includes a CO2 generating means 11, a CO2 capture means 12, and a receiving unit 13 (a receiving unit of the CO2 capture mechanism).

[0034] The CO2 generating means 11 is a small power generating device installed at the business premises. Since this is a power generating device that generates CO2 during power generation, a thermal power generating device can be used. In addition, it is preferable that the CO2 generating means is a cogeneration system installed at the business premises. Since cogeneration systems are often installed in business establishments, the number of CO2 capture mechanisms can be increased by using the cogeneration system as a means for generating CO2 and attaching a CO2 capture means to the cogeneration system. An outlet through which CO2 is discharged from the CO2 generation means 11 and the CO2 capture means 12 are connected by a pipeline or the like, and the CO2 generated in the CO2 generation means 11 is sent to the CO2 capture means 12.

[0035] The CO2-containing gas generated from the CO2 generation means is introduced into the CO2 capture means 12. CO2 is adsorbed and captured in the CO2 capture means 12. The CO2-containing gas that has passed through the CO2 capture means 12 passes through a chimney or the like and is discharged as exhaust gas.

[0036] The CO2 capture means 12 preferably includes a structure for CO2 capture in which reaction layers for adsorbing and desorbing CO2 and heating layers for heating the reaction layers are alternately stacked. The reaction layers preferably include a substrate, a support, and an adsorbent for adsorbing and desorbing CO2 supported on the support.

[0037] The substrate is a basic member constituting the reaction layer, and a support is coated on the portion of the substrate that comes into contact with the gas containing CO2, and the adsorbent is supported on the support. Alternatively, the substrate may also serve as a support, and the adsorbent may be supported on the substrate that also serves as a support. The material constituting the substrate is not particularly limited, but may be at least one selected from the group consisting of carbon, metal, and highly thermally conductive ceramic.

[0038] Examples of the support include Al2O3, TiO2, SiO2, ZrO2, zeolite, carbon, etc. In practice, these can be made into supports made of the above materials by using a suspension in which the above oxides are dispersed in a dispersion medium such as an inorganic sol, an organic binder, or a mixture of these, and attaching the suspension to the surface of a substrate, followed by drying and firing.

[0039] The adsorbent includes an amine compound, and specific examples of the amine compound include polyethyleneimine, monoethanolamine, diethanolamine, triethanolamine, tetraethyleneaminepentamine, methyldiethanolamine, dibutylamine, ethylenediamine, diethylenetriamine, triethylenetetramine, hexaethylenediamine, benzylamine, metaxylenediamine, polyethyleneimine, ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, and pentaethylenehexamine.

[0040] The amine compound may be supported on the support by, for example, passing an aqueous solution of the amine compound through the through-holes of the honeycomb structure or immersing the honeycomb structure in an aqueous solution of the amine compound. Alternatively, an aqueous solution or an alcohol solution of the amine compound may be mixed with particles constituting the support, and the particles or the like may be sufficiently impregnated with the solution, and then the partition walls inside the reaction layer may be covered with the support containing the amine compound, and the water or alcohol may be removed. By the supporting step of impregnating the partition walls with the amine compound, a CO2 adsorbent having residues derived from the amine compound on the surfaces of the partition walls is obtained.

[0041] The heating layer is made of a plate-like heat transfer material or heating element, or is made of a heat transfer material having one or a plurality of through holes which serve as a flow path for a heating fluid, and is bonded to the reaction layer. The heating layer is desirably made of at least one material selected from the group consisting of carbon, metal and ceramic.

[0042] FIG. 2 is a perspective view that illustrates an example of a structure for CO2 capture. As shown in Figure 2, the structure 200 is composed of a honeycomb structure 220, which is a ceramic reaction layer in which a large number of through holes 221, which serve as flow paths for gases including CO2, are arranged in parallel in the longitudinal direction separated by partition walls 222, and a heat transfer body 210, which is a heating layer in which a plurality of through holes 211, which serve as flow paths for heat sources such as water vapor, are arranged in parallel in the extension direction of the through holes 211, separated by partition walls 212. These are layered so that the flow paths (through holes 221) of the honeycomb structure 220 intersect with the flow paths (through holes 211) of the heat transfer body 210.

[0043] In addition, an adhesive layer 230 is formed between the honeycomb structure 220 and the heat transfer body 210, and the honeycomb structure 220 and the heat transfer body 210 are bonded to each other by this adhesive layer 230.

[0044] In the structure 200 shown in FIG. 2, in the honeycomb structure 220, through-holes 221 are exposed on the left front side and right rear side, and in the heat transfer body 210, through-holes 211 are exposed on the right front side and left rear side. Therefore, in honeycomb structure 220, gas containing CO2 flows from the front left side to the rear right side or in the opposite direction, and in heat transfer body 210, gas containing water vapor, etc. flows from the front right side to the rear left side or in the opposite direction. Since the two flow paths intersect at right angles, it is easy to circulate the two types of fluids (gases), and heat from heat transfer body 210 can be efficiently transferred to honeycomb structure 220.

[0045] In the structure 200, the honeycomb structure 220 constituting the structure 200 is composed of one honeycomb structure 220, but a plurality of small honeycomb structures may be combined and bonded together to form a honeycomb structure, and the heat transfer body 210 may also be a plurality of small heat transfer bodies combined and bonded together to form a heat transfer body.

[0046] When the structure 200 is operated as a CO2 recovery means, first, a CO2-containing gas is introduced into the honeycomb structure 220 (reaction layer), and after the CO2 is adsorbed and absorbed, the gas is discharged through a chimney. Steam gas is introduced into the heat transfer body 210 (heating layer) of the structure 200 that has sufficiently adsorbed and absorbed CO2, and CO2 is desorbed and released from the honeycomb structure 220 of the structure 200 that is heated by the heat transfer body 210. The desorbed and released CO2 is introduced into a pump together with the CO2 capture gas, and after leaving the pump, is stored as CO2, and the CO2 generated by the CO2 generation means is captured.

[0047] The receiving unit 13 of the CO2 capture mechanism receives the CO2 capture amount information transmitted from the demand information processing terminal 30 described later. Based on the CO2 capture amount information received by the receiving unit 13, the CO2 generation means 11 and the CO2 capture means 12 are operated to perform the CO2 capture operation.

[0048] [CO2 consumer terminal] The CO2 consumer terminal 20 includes an input unit 21 and a transmission unit 22 (a transmission unit of the CO2 consumer terminal). The CO2 consumer terminal 20 is a terminal owned by a CO2 consumer, and may be a personal computer, tablet, smartphone, or other information terminal.

[0049] The input unit 21 is an input device provided in the CO2 consumer terminal 20, and may use input devices such as a keyboard, a mouse, a touch panel, and a voice input device (including a smart speaker, etc.). In the input unit 21, CO2 demand information is input by a CO2 demander. The CO2 demand information is preferably at least one piece of information selected from the group consisting of a CO2 delivery form, a required amount of CO2, a delivery location, a desired delivery time, and a desired purchase price. The form in which CO2 is delivered means in cylinders, dry ice, gas, etc. The required amount of CO2 means the required number of cylinders, weight of dry ice, weight of gas, etc. The delivery location and desired delivery time are information regarding the location and time that the CO2 consumer desires for delivery. The desired purchase price refers to the price per unit of CO2 purchased (price per cylinder, per kg of dry ice, per kg of gas, etc.). Of these pieces of information, the necessary information is input to the input unit 21 by the CO2 consumer.

[0050] Moreover, the input unit is preferably an application provided to the CO2 consumer terminal. By installing an application that allows CO2 users to easily input their CO2 demand information on their terminals in advance, CO2 users can input their demand information themselves. Then, it is possible to connect (match) CO2 supply sources and CO2 users on the network. In this specification, the term "network" refers to a network via a telecommunication line or the Internet.

[0051] The application may have a function that enables a CO2 consumer to check information on a CO2 supply source on the network. The information on the CO2 supply source may include information on the price of CO2, information on the delivery date when CO2 is ordered, information on the operation status of the CO2 capture mechanism, information on the amount of CO2 stored in the CO2 storage mechanism, etc. When using such a function, it is only necessary to provide the CO2 consumer terminal with a receiving unit capable of receiving information from the network.

[0052] The transmission unit 22 transmits the demand information inputted to the input unit 21 to a demand information processing terminal 30 (described later) via a network.

[0053] [Demand information processing terminal] The demand information processing terminal 30 includes a receiving unit 31 , a calculation unit 32 , and a transmitting unit 33 .

[0054] The demand information processing terminal 30 is a terminal that can be managed by an operating company that operates the entire CO2 capture system 1. As the demand information processing terminal 30, a personal computer, tablet, smartphone, or other information processing terminal owned by the operating company can be used.

[0055] The receiving unit 31 receives the demand information transmitted from the transmitting unit 22 of the CO2 demander terminal 20. The calculating unit 32 calculates the amount of CO2 to be recovered by the CO2 capture mechanism 10 based on the demand information received by the receiving unit 31. The calculation unit 32 is provided with a control unit 34. The control unit 34 includes, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory). The ROM included in the control unit 34 stores a computer program and the like for calculating the amount of CO2 captured based on demand information in the calculation unit 32. The CPU in the control unit 34 executes a computer program stored in the ROM or a storage unit 35 described later, and realizes a process of calculating the amount of CO2 captured based on the demand information. The RAM included in the control unit 34 temporarily stores data used during the execution of calculations. The configuration of the control unit 34 is not limited to the above configuration, and may be one or more arithmetic circuits including other volatile or non-volatile memories or the like.

[0056] The storage unit 35 stores computer programs used by the control unit. The memory unit 35 stores a trained artificial intelligence model 36, and the calculation unit 32 can use the artificial intelligence model to calculate the amount of CO2 captured. The calculation of the amount of CO2 captured using an artificial intelligence model will be described later. Specific examples of calculations that can be performed by the calculation unit 32 will also be described later.

[0057] The transmitting unit 33 transmits the CO2 capture amount information calculated in the calculating unit 32 to the CO2 capture mechanism 10. The receiving unit 13 of the CO2 capture mechanism 10 receives the CO2 capture amount information transmitted from the demand information processing terminal 30. Based on the CO2 capture amount information received by the receiving unit 13, the CO2 generation means 11 and the CO2 capture means 12 are operated to perform CO2 capture operation.

[0058] The CO2 capture system of the present invention includes at least a CO2 capture mechanism, a CO2 consumer terminal, and a demand information processing terminal. A CO2 demand information is inputted into an input section of a CO2 demand terminal by a CO2 demander, and the demand information is transmitted to a demand information processing terminal. The demand information processing terminal has a calculation unit, which calculates the amount of CO2 to be captured by the CO2 capture mechanism based on the demand information, and transmits the calculated CO2 capture amount information to the CO2 capture mechanism. The CO2 capture mechanism performs CO2 capture operation based on the received CO2 capture amount information. In this way, optimal CO2 capture can be performed according to the CO2 demand information. That is, according to the CO2 capture system of the present invention, CO2 can be captured near consumers, and the consumers can use the captured CO2.

[0059] [CO2 capture system using CO2 storage mechanism] The CO2 capture system of the present invention may further include a CO2 storage mechanism that stores the CO2 captured by the CO2 capture mechanism. The CO 2 capture system 1 shown in FIG. The CO2 storage mechanism 40 stores the CO2 captured by the CO2 capture mechanism 10. An example of the CO2 storage mechanism 40 is a warehouse that stores CO2 cylinders 41. The form of CO2 stored in the CO2 storage mechanism 40 is not limited to the form of a CO2 cylinder, but may be stored in another form such as dry ice. The CO2 storage mechanism may be located on the same site as the CO2 capture mechanism or on a different site, but it is preferable that it is located not too far from the CO2 capture mechanism constituting the CO2 capture system and the consumers who use the CO2 capture system.

[0060] The CO2 storage mechanism 40 has a CO2 storage amount memory unit 42 that stores the amount of CO2 stored in the CO2 storage mechanism 40, and a transmission unit 43 that transmits the CO2 storage amount information stored in the CO2 storage amount memory unit 42 to the demand information processing terminal 30.

[0061] The demand information processing terminal 30 receives the CO2 storage amount information transmitted from the transmitter 43 of the CO2 storage mechanism at the receiver 31 of the demand information processing terminal. The calculation unit 32 can calculate the amount of CO2 captured by the CO2 capture mechanism 10 by using the received CO2 storage amount information in addition to the CO2 demand information. In a CO2 recovery system designed to calculate the CO2 recovery amount using CO2 storage amount information, a computer program for calculating the CO2 recovery amount using CO2 demand information and CO2 storage amount information is stored in the control unit 34 or memory unit 35 provided in the calculation unit 32.

[0062] When calculating the amount of CO2 captured, by using information on the amount of CO2 stored in addition to information on CO2 demand, the amount of CO2 captured by the CO2 capture mechanism can be calculated as a more optimal value. Assuming that there is a demand for the same amount of CO2, there may be cases where it is better not to capture CO2 when the amount of CO2 stored is large, and cases where it is better to capture CO2 when the amount of CO2 stored is small, so using information on the amount of CO2 stored is useful.

[0063] [CO2 capture system using delivery terminals] The CO2 capture system of the present invention may further include a deliverer terminal as a component thereof. If the CO2 capture system includes a deliverer terminal, it is preferable that the calculation unit of the demand information processing terminal further calculates a CO2 delivery route for delivering the CO2 captured by the CO2 capture mechanism to the CO2 consumer, and transmits the CO2 delivery route information calculated in the calculation unit from the transmission unit of the demand information processing terminal to a deliverer terminal owned by the deliverer.

[0064] The CO 2 recovery system 1 shown in FIG. The deliverer terminal 50 is a terminal for receiving CO2 delivery route information from the transmission unit 33 of the demand information processing terminal 30 by a deliverer who delivers the CO2 captured by the CO2 capture mechanism to a CO2 consumer. In this specification, a deliverer is typically a delivery company, either a natural person or a legal entity, that owns transportation equipment for delivery (such as a truck), but the deliverer may not be a natural person or a legal entity, but may be the transportation equipment itself, such as an autonomous vehicle or drone. If the deliverer is a delivery company, the deliverer terminal may be a personal computer, tablet, smartphone, or other information processing terminal owned by the delivery company. In the case where the deliverer is the transport equipment itself, the deliverer terminal is integrated with the transport equipment, and an information processing device installed inside the transport equipment functions as the deliverer terminal. In this specification, the deliverer terminal integrated with the transport equipment that is the deliverer is also considered to be a deliverer terminal "owned" by the deliverer.

[0065] In a CO2 capture system equipped with a distributor terminal, delivery information, which is information necessary for delivering CO2 to consumers, is used from among the demand information inputted in the CO2 consumer terminal. The delivery information includes information such as the delivery location for each CO2 consumer, the desired delivery time, the delivery form of CO2, and the required amount of CO2. In addition, the delivery information may include individual agreements made between the distributor and the consumer.

[0066] The calculation unit 32 of the demand information processing terminal 30 performs calculations using the delivery information, and calculates a CO2 delivery route for delivering the CO2 captured by the CO2 capture mechanism to the CO2 demander. In a CO2 capture system designed to calculate a CO2 delivery route using delivery information, a control unit 34 or memory unit 35 provided in the calculation unit 32 stores a computer program for calculating a CO2 delivery route using the delivery information. In addition, the control unit 34 or memory unit 35 provided in the calculation unit 32 may pre-store information such as the location of the delivery person, the location of the CO2 capture mechanism, the location of the CO2 storage mechanism, the location of each consumer, and road information between each point.

[0067] The distributor delivers CO2 to multiple CO2 consumers who use the same CO2 capture system. Therefore, when calculating the CO2 delivery route, the distributor calculates the CO2 delivery route so that the delivery route is optimized (optimized from the viewpoint of the shortest delivery time, the shortest delivery route, etc.) based on the delivery information of the delivery locations and desired delivery times of the multiple consumers.

[0068] The CO2 delivery route information calculated by the calculation unit 32 is transmitted to the deliverer terminal 50 from the transmission unit 33 of the demand information processing terminal. If the deliverer is a delivery company, the delivery company refers to the CO2 delivery route information transmitted to the deliverer terminal 50 and delivers the CO2 to each CO2 consumer in accordance with the CO2 delivery route information. If the deliverer is the transportation equipment itself, the CO2 delivery route information sent to the transportation equipment becomes a command signal to move the transportation equipment. The transportation equipment delivers the CO2 to the CO2 consumer according to the received CO2 delivery route information.

[0069] [CO2 flow in the CO2 capture system] FIG. 3 is a block diagram that illustrates an example of the flow of CO2 transfer in the CO2 capture system of the present invention. The arrows in Figure 3 indicate the direction in which CO2 is exchanged between each element. FIG. 3 shows an example in which CO2 is exchanged between a CO2 capture mechanism 10, a CO2 storage mechanism 40, a deliverer 60, and a CO2 consumer 70. The CO2 exchanged in the CO2 capture system is generated by CO2 generation means 11 in the CO2 capture mechanism 10 and captured by CO2 capture means 12. The CO2 captured by the CO2 capture mechanism 10 is either delivered to the deliverer 60 or temporarily stored in the CO2 storage mechanism 40 in the form of a CO2 cylinder 41. Whether the CO2 captured by the CO2 capture mechanism 10 is delivered to the deliverer 60 or stored in the CO2 storage mechanism 40 is determined based on the CO2 capture amount information received by the CO2 capture mechanism 10 from the demand information processing terminal and the CO2 delivery route information received by the deliverer 60 from the demand information processing terminal.

[0070] The deliverer 60 receives CO2 from the CO2 capture mechanism 10 or the CO2 storage mechanism 40 based on the CO2 delivery route information received from the demand information processing terminal. When the deliverer 60 receives CO2 from the CO2 capture mechanism 10, the deliverer 60 receives the CO2 in a transportable form such as a CO2 cylinder, but the CO2 cylinder between the CO2 capture mechanism 10 and the deliverer 60 is not shown in Figure 3.

[0071] The deliverer 60 delivers CO2 to a plurality of CO2 consumers 70 who use the same CO2 capture system. The deliverer 60 delivers CO2 to each CO2 consumer 70 according to the CO2 delivery route information received from the demand information processing terminal.

[0072] [Calculation taking into account CO2 demand or CO2 price] In the CO2 capture system of the present invention, when the demand for CO2 is low or the price of CO2 is low, calculations based on demand information result in CO2 capture volume information indicating that CO2 capture operation will not be performed, and the CO2 capture volume information is transmitted from the transmitting unit of the demand information processing terminal to the CO2 capture mechanism, so that the CO2 capture mechanism does not perform CO2 capture operation. In the following description, a CO2 capture system that performs calculations taking into account the demand for CO2 is referred to as a demand-considered CO2 capture system. Also, in the following description, a CO2 capture system that performs calculations taking into account the price of CO2 is referred to as a price-considered CO2 capture system.

[0073] In the demand-aware CO2 capture system, the demand amount of CO2 contained in the demand information inputted at the CO2 demander terminal is used for calculation. In this case, it is preferable to use the demand information including the demand amount of CO2 and the CO2 storage amount information transmitted from the CO2 storage mechanism in combination for the calculation. If a comparison is made between the CO2 demand and the CO2 storage volume and the calculation results show that the CO2 storage volume is greater and that the demand can be met with the amount of CO2 stored in the CO2 storage mechanism, then information indicating that the CO2 capture volume is zero is sent to the CO2 capture mechanism, and the CO2 capture mechanism will not perform CO2 capture operation. In addition, even if the CO2 storage amount is greater than the CO2 demand, if the remaining amount of CO2 storage after subtracting the CO2 demand from the CO2 storage amount is small, CO2 capture operation may be performed.

[0074] In addition, when the demand for CO2 is low, if a CO2 capture operation is performed to capture a small amount of CO2, the cost of capturing CO2 will be high, and a loss may occur due to the capture of CO2. In such a case, it is preferable not to perform the CO2 capture operation.

[0075] In the price-sensitive CO2 capture system, the price of CO2 contained in the demand information inputted at the CO2 demander terminal is used for calculation. A calculation is made by comparing the price of CO2 paid by consumers (the income that the operator of the CO2 capture system receives from the supply of CO2) with the cost required to capture that CO2 by the CO2 capture mechanism.If the calculation result indicates that it is better not to capture CO2, information on the amount of CO2 captured that is zero is sent to the CO2 capture mechanism, and the mechanism is prevented from performing CO2 capture operation.

[0076] The CO2 capture mechanism has a CO2 generating means, which is a small power generating device installed at the business premises. Power generation by the small power generating device may be carried out if electricity is needed, regardless of the demand for CO2 or the price of CO2. Power generation by the small power generating device generates CO2, but if the calculation results show that it is better not to capture CO2, it may be decided not to perform CO2 capture operation. In this case, the CO2 generated by power generation will be released into the atmosphere without being captured.

[0077] [CO2 capture system using artificial intelligence model] The CO2 capture system of the present invention may be configured so that a calculation unit of the demand information processing terminal estimates demand information using a trained artificial intelligence model, and calculates the amount of CO2 to be captured by the CO2 capture mechanism based on both the demand information received by a receiving unit of the demand information processing terminal and the demand information estimated by the artificial intelligence model. The artificial intelligence model is a machine learning learning model including deep learning, and is composed of, for example, a neural network.

[0078] The trained artificial intelligence model can be stored as a computer program in the storage unit 35 included in the calculation unit 32 of the demand information processing terminal 30 in the CO2 capture system 1 shown in Fig. 1. The computer program may also be stored in a storage medium such as a CD-ROM, a DVD-ROM, or a HDD.

[0079] As the artificial intelligence model, a trained artificial intelligence model that has learned the relationship between weather conditions and demand information can be used. In the following description, this will be referred to as a weather condition trained artificial intelligence model. In addition, as the artificial intelligence model, a trained artificial intelligence model that has learned the relationship between past demand information from CO2 demanders and demand information received from CO2 demanders can be used. In the following description, this will be referred to as a past demand trained artificial intelligence model.

[0080] (CO2 capture system using artificial intelligence model trained on weather conditions) In the CO2 capture system of the present invention, the calculation unit is equipped with a trained artificial intelligence model that has learned the relationship between weather conditions and demand information based on teacher data that inputs weather conditions within the area in which the CO2 capture system is operated and outputs CO2 demand information, and the calculation unit may input weather conditions within the area in which the CO2 capture system is operated to the trained artificial intelligence model to estimate CO2 demand information, and calculate the amount of CO2 to be captured by the CO2 capture mechanism based on both the demand information received by the receiving unit and the demand information estimated by the artificial intelligence model.

[0081] To create an artificial intelligence model that has learned weather conditions, training data is prepared that inputs the weather conditions within the area in which the CO2 capture system will be operated and outputs CO2 demand information. Weather conditions that affect the demand for CO2 include the weather, temperature (maximum and / or minimum temperature), humidity, discomfort index, etc. in the area in which the CO2 capture system is operated. By inputting the prepared training data into the artificial intelligence model, an artificial intelligence model that has learned weather conditions can be obtained.

[0082] When operating the CO2 capture system of the present invention, the weather conditions within the area in which the CO2 capture system is operated are input to the weather condition learned artificial intelligence model. The "weather conditions within the area in which the CO2 capture system will be operated" that is input to the weather condition-trained artificial intelligence model does not refer to the weather conditions used as training data, but rather to the weather conditions at the time the CO2 capture system will be operated. "Weather conditions at the time of operating the CO2 capture system" does not mean the weather conditions at that time (moment). For example, when using maximum temperature as a weather condition, the maximum temperature of that day may be used, or the average value of the maximum temperature over the past few days including that day may be used.

[0083] The weather conditions may be input to the artificial intelligence model by the operator of the CO2 capture system through a separate input unit (not shown) in the demand information processing terminal, or may be input by the consumer through the CO2 consumer terminal. In addition, a program can be set up to receive necessary weather conditions via a network and automatically input the received weather conditions into an artificial intelligence model that has learned weather conditions, so that weather conditions can be input to the artificial intelligence model that has learned weather conditions on a regular basis.

[0084] The calculation unit of the demand information processing terminal inputs the weather conditions within the area where the CO2 capture system is operated into the trained artificial intelligence model to estimate CO2 demand information. The demand information processing terminal also inputs the demand information received from the CO2 consumer terminal, and calculates the amount of CO2 to be captured by the CO2 capture mechanism based on both the demand information received from the CO2 consumer terminal and the demand information estimated by the artificial intelligence model. The CO2 capture amount information calculated in the calculation unit is transmitted to the CO2 capture mechanism. In the CO2 capture mechanism, the CO2 generation means and the CO2 capture means are operated based on the CO2 capture amount information, thereby performing a CO2 capture operation.

[0085] If the results of estimating CO2 demand information using an AI model that has learned the relationship between factors that affect CO2 demand, such as weather conditions, and CO2 demand information are used to calculate the amount of CO2 captured by the CO2 capture mechanism, it will be possible to predict increases in CO2 demand in advance and take measures such as increasing the amount of CO2 captured in advance. This makes it possible to create a CO2 capture system that can respond to increases and decreases in CO2 demand.

[0086] (CO2 capture system using artificial intelligence model trained on past demand) In the CO2 capture system of the present invention, the calculation unit is equipped with a trained artificial intelligence model that has learned the relationship between past demand information from CO2 consumer and the demand information received from CO2 consumer based on training data that inputs a history of past demand information from a specific CO2 consumer within the range in which the CO2 capture system is operated and outputs the demand information received from the CO2 consumer, and the calculation unit may input the history of past demand information from the CO2 consumer to the trained artificial intelligence model to estimate CO2 demand information from the CO2 consumer, and calculate the amount of CO2 to be captured by the CO2 capture mechanism based on both the demand information received by the receiving unit and the demand information estimated by the artificial intelligence model.

[0087] When creating an artificial intelligence model that has learned past demand, training data is prepared in which the past demand information history from specific CO2 consumers within the area in which the CO2 capture system is operated is input, and the demand information received from those CO2 consumers is output. The history of past demand information refers to information such as the CO2 delivery method, required amount of CO2, delivery location, desired delivery time, and desired purchase price contained in the history of demand information that a specific CO2 consumer has previously entered into a CO2 consumer terminal. From the history of past demand information, the frequency (order interval) at which the CO2 consumer requires CO2 is obtained, and further, the amount of CO2 required when CO2 is required is obtained. From this information, it is preferable to obtain the amount of CO2 required by the CO2 consumer within a specific period (e.g., one month) and use this as training data. It is believed that by using the history of past demand information from a specific CO2 consumer as training data, it is possible to predict in advance an increase in CO2 demand from that consumer. By inputting the prepared training data into the artificial intelligence model, an artificial intelligence model that has been trained on past demand can be obtained.

[0088] When operating the CO2 capture system of the present invention, a history of past demand information from a specific CO2 consumer is input into the past demand learned artificial intelligence model. The "history of past demand information from specific CO2 consumers" that is input into the past demand-trained artificial intelligence model does not refer to the history of past demand information used as training data, but rather to the history of demand information for a specific period going back from the time the CO2 capture system is put into operation. For example, if the frequency (order interval) at which the CO2 consumer requires CO2 is used as past demand information, it is preferable to use a history of demand information for a period going back longer than the period used to estimate the average order interval.

[0089] The operator of the CO2 capture system may input the history of demand information for the period going back a specific period from a separate input unit (not shown) in the demand information processing terminal, but it is preferable to store past demand information received from specific CO2 demanders in a memory unit in the demand information processing terminal and to input the history of demand information by referring to the history of demand information for the required period from the memory unit.

[0090] The historical demand information from that long period back is input into the AI ​​model with past demand learning to estimate the demand information for CO2. The demand information processing terminal also inputs the demand information received from the CO2 consumer terminal, so the amount of CO2 to be captured by the CO2 capture mechanism is calculated based on both the demand information received from the CO2 consumer terminal and the demand information estimated by the AI ​​model. The CO2 capture amount information calculated in the calculation unit is transmitted to the CO2 capture mechanism. In the CO2 capture mechanism, the CO2 generation means and the CO2 capture means are operated based on the CO2 capture amount information, thereby performing a CO2 capture operation.

[0091] If the results of estimating CO2 demand information using an AI model that has learned the relationship between the history of past demand information from CO2 consumers and CO2 demand information are used to calculate the amount of CO2 captured by the CO2 capture mechanism, it will be possible to predict increases in CO2 demand from the consumer in advance and take measures such as increasing the amount of CO2 captured in advance. This makes it possible to create a CO2 capture system that can respond to increases and decreases in CO2 demand.

[0092] [Scope of operation of CO2 capture system] In the CO2 capture system of the present invention, the range in which the CO2 capture system is operated is not particularly limited, but it is preferable that the range includes CO2 consumers within 50 km of one CO2 capture mechanism. The CO2 capture system of the present invention captures CO2 near the consumer without transporting it long distances, allowing the consumer to use the captured CO2. This makes it possible to create a cycle of CO2 capture and use within a small area of ​​within 50 km of the CO2 capture facility. [Explanation of symbols]
