[0020] [Problems to be Solved by the Present Disclosure]

[0021] The demand for reducing carbon dioxide is getting higher and higher. As disclosed in Patent Documents 1 and 2, the entities promoting reduction are not limited to public groups and enterprises, but are also promoting reduction at the individual level. Due to the popularity of smartphones and personal computers in recent years, electricity consumption at the individual level is on the rise. In particular, due to the expansion of the use of various application software represented by music, images, games and SNS in the so-called entertainment field, electricity consumption has increased significantly. The countermeasures for individual users of application software to contribute to the reduction of carbon dioxide are to reduce electricity consumption itself by reducing the use of application software, or to replace the energy used with so-called green energy.

[0022] The aforementioned measures merely reduce carbon dioxide emissions. They do not reduce the amount of carbon dioxide already released into the atmosphere. Patent Documents 1 and 2 only disclose reducing carbon dioxide emissions through the use of energy-saving equipment and electric vehicles. They do not disclose reducing the amount of carbon dioxide actually present in the atmosphere.

[0023] The present disclosure aims to promote carbon dioxide reduction activities mainly at the individual level and to promote the reduction of carbon dioxide actually present in the atmosphere by enabling individuals to quantitatively obtain the effect of carbon dioxide reduction.

[0024] [Effects of the Present Disclosure]

[0106] [Details of the embodiments of the present disclosure]

[0107] The embodiments of the present disclosure are described with reference to the accompanying drawings. It should be noted that the embodiment described below represents a specific example of the present disclosure. The numerical values, shapes, materials, components, configurations and connection methods of the components, steps, etc. described below are examples of an embodiment. In addition, each figure is a schematic diagram and may not be a strict depiction. The same components are marked with the same figure marks in the figures. The description of the functions of the same components is appropriately omitted. It should be noted that in the following description and drawings, carbon dioxide is sometimes expressed as CO2 in the molecular formula.

[0108] <Implementation Method>

[0109] (Basic structure of the CO2 reduction promotion system)

[0110] Reference Figure 1 , the basic structure of the carbon dioxide reduction promotion system 10 disclosed in the present invention is described. Figure 1 , two users are shown as an example, namely user 1 and user 2. User 1 uses user terminal 11, and user 2 uses user terminal 12. Application software (hereinafter sometimes referred to as "application") provided by or managed by a service provider 20 is installed on each of user terminals 11 and 12.

[0111] In the present disclosure, applications broadly include software that users make to operate, for example, on user terminals, and software that serves as an interface for providing services to users. In the present disclosure, installation is not limited to the case where software is loaded on a user terminal and operated on the user terminal. For example, the state where a service is provided to a user terminal by operating software placed on an external server or cloud via a network from an application on the user terminal is also interpreted as being included in installation. Similarly, the case of utilizing an application in a user terminal includes the case of direct operation on the user terminal and the case of indirect operation of the software via a network. In the following description, two users are shown as an example, but the number of users is not limited to this, and multiple users of more than one person are envisioned in the system of the present disclosure. User terminals are, for example, smartphones, tablet terminals, game consoles, or personal computers. It should be noted that applications can also be utilized in terminals provided by service operators.

[0112] A service provider 20, acting as an application provider or operator, operates a service provider device 21. The service provider device 21 performs various data processing tasks for the service provider 20 and is typically a general-purpose computer such as a personal computer, workstation, or server. The service provider device 21 can communicate with the user terminals 11 and 12 via a network 50. Through communication between the service provider device 21 and the user terminals 11 and 12, the service provider device 21 can understand the usage status of applications in the user terminals 11 and 12.

[0113] The CO2 reduction operator 30 is an operator that operates the CO2 reduction device 32. The CO2 reduction operator 30 operates the CO2 reduction device 32 in response to a request from another person and reports the amount of CO2 reduced to the requester. The CO2 reduction device 32 is a device that reduces, captures, and reduces CO2 from the atmosphere, various exhaust gases, and other gases. A specific example of the CO2 reduction device 32 will be described later. The CO2 reduction operator 30 operates a reduction operator device 31. The reduction operator device 31 is a device that performs externally requested processing and data processing related to the CO2 reduction performed by the CO2 reduction device 32. The reduction operator device 31 is typically a general-purpose computer such as a personal computer, workstation, or server. The reduction operator device 31 can communicate with other devices via a network 50.

[0114] The CO2 emissions monitor 40 is, for example, a national or local public entity or public institution, or a commissioned operator. The CO2 emissions monitor 40 accepts reports of CO2 reductions and emission reductions and certifies them. Certification involves demonstrating contributions to reductions, providing compensation corresponding to these reductions, and so on. The CO2 emissions monitor 40 owns and operates a monitor device 41. Monitor device 41 processes data related to the aforementioned certification and is typically a general-purpose computer. Monitor device 41 can communicate with other devices via a network 50.

[0115] <First embodiment>

[0116] One embodiment of the present disclosure is a carbon dioxide reduction promotion system 10 in which a user 1 who utilizes an application provided by a service provider 20 on a user terminal 11 receives contribution points from the service provider 20 based on the actual usage of the application. The following description of the system uses user 1 as a representative example, but multiple users are possible in the embodiments, and the number of users is not limited.

[0117] Reference Figure 1 as well as Figure 2Next, the operation of the carbon dioxide reduction promotion system 10 according to the first embodiment of the present disclosure will be described.

[0118] The service operator device 21 receives application usage records 81 and user identification information 82 from the user terminal 11 through communication with the user terminal 11. The usage records 81 are associated with the user identification information 82 of the user 1 and stored in the service operator device 21. The service operator device 21 creates request information 83. Request information 83 includes the amount of CO2 reduction work performed according to the usage records 81. The service operator device 21 transmits the created request information 83 to the reduction operator device 31. The service operator device 21 receives a reduction performance value 84 corresponding to the completion of the CO2 reduction work from the reduction operator device 31. The service operator device 21 transmits the reduction performance value 84 to the supervisor device 41. The supervisor device 41 issues CO2 credits 85 corresponding to the reported reduction performance value 84. The service operator device 21 receives the CO2 credits 85 from the supervisor device 41. The service operator device 21 calculates contribution points 86 based on the received CO2 credits 85 and the usage records 81 of the user terminal 11. The service operator device 21 transmits the calculated contribution points 86 to the user terminal 11 .

[0119] The transmission of contribution points 86 to the user terminal 11 is not limited to direct transmission of the contribution points 86 themselves. As is generally implemented in many point systems, the points themselves can also be configured as virtual numerical values, managed as numerical values ​​assigned to users registered on the server of the operator that utilizes the points (e.g., point balance). In this case, the contribution points 86 are transmitted to the user terminal 11 in the form of notification of the addition of contribution points 86. Furthermore, the transmission of contribution points 86 to the user terminal 11 is not limited to unsolicited transmission from the service operator device 21; it can also be notification in the form of a numerical value returned by the user 1 based on data referenced by the service operator device 21, etc.

[0120] The above description relates to user 1 and user terminal 11. If there are multiple users, such as user 2, the same information applies to each user. In the case of multiple users, the request information 83 sent from the service operator device 21 to the reduction operator device 31 may aggregate the requests related to multiple users into a single request information 83. Furthermore, the reduction performance value 84 sent from the service operator device 21 to the supervisor device 41 and the CO2 credits 85 received from the supervisor device 41 may also be the total value related to multiple users.

[0121] In the present disclosure, the contents of tangible and intangible objects that have economic value and can be traded and that are granted as certification are collectively referred to as carbon dioxide credits 85. As an example, at the time of this application, the J-credit system is in use in Japan (reference URL: https: / / japancredit.go.jp / ). The system is described as "The J-credit system refers to a system in which the state certifies the reduction in emissions of CO2, etc. brought about by the introduction of energy-saving equipment, the use of renewable energy, and the reduction in CO2, etc. brought about by appropriate forest management as 'credits'. This system is a system that is a developmental integration of the domestic credit system and the offset credit (J-VER) system and is operated by the state. The credits created through this system can be flexibly used for various purposes such as achieving the goals of the Japan Business Federation's carbon neutrality action plan and carbon offsets." The owner of the credit can obtain economic and social benefits through various methods such as selling credits.

[0122] (User Terminal)

[0123] User 1 is, for example, an individual or legal entity that owns user terminal 11. "Ownership" is not limited to a legal relationship and may also encompass a person who substantially benefits from user terminal 11. User terminal 11 may typically be a smartphone, tablet, or personal computer used by user 1. User terminal 11 is configured to communicate via network 50.

[0124] Reference Figure 3 , an application 110 provided by a service provider 20 is installed on the user terminal 11. The user terminal 11 includes a usage performance transmission unit 120. The usage performance transmission unit 120 transmits the usage performance 81 of the application 110 and the user identification information 82 unique to the user 1 and the user terminal 11 to a service provider device 21 owned by the service provider 20. Furthermore, the user terminal 11 includes a points reception unit 130 for receiving contribution points 86 from the service provider device 21. Other basic components of the user terminal 11 as its original function are not shown. For example, if the user terminal 11 is a smartphone, the basic components include an input unit, a communication unit, a display unit, and the like.

[0125] User 1 uses user terminal 11 to access application 110. Usage record sending unit 120 compiles statistics on usage record 81 of application 110 and sends it to service operator device 21 at predetermined times. Usage record 81 primarily represents the time application 110 is used, but may also include specific usage information such as the date and time, location, and the content of application 110's actions. The timing for sending usage record 81 is not particularly limited; examples include when application 110 usage ends, at regular times such as once a day or once an hour, or at a user-specified time. In addition to sending usage record 81, usage record sending unit 120 also sends user identification information 82 specific to user 1 and user terminal 11 to service operator device 21. User identification information 82 may be, for example, user 1's name or a pre-assigned ID. Alternatively, user identification information 82 may be a device number or address information specific to user terminal 11.

[0126] The points receiving unit 130 receives contribution points 86 provided by the service operator 20 from the service operator device 21. Contribution points 86 are not particularly limited, as long as they are contribution points that can directly or indirectly benefit the user 1. Contribution points 86 can be, for example, points from various known point systems, mileage points from mileage systems, electronic currency, virtual currency, or discount coupons. It should be noted that the points receiving unit 130 and the usage performance sending unit 120 can also be configured as software integrated with the application 110. That is, the points receiving unit 130 and the usage performance sending unit 120 can also be configured as part of the functionality of the application 110.

[0127] (Service Operator Device and Reduction Operator Device)

[0128] like Figure 1 As shown in FIG. 2 , the service operator device 21 is a device operated by the service operator 20. The reduction operator device 31 is a device operated by the carbon dioxide reduction operator 30. Figure 2 As shown, the service operator device 21 is a device for performing the following series of operations: the service operator 20 obtains the actual usage performance 81 of the application 110 of user 1, requests the CO2 reduction operator 30 to perform CO2 reduction work corresponding to the actual usage performance 81, reports the actual reduction performance value 84 to the CO2 emission supervisor 40 and receives CO2 credits 85, and then awards contribution points 86 corresponding to the CO2 credits 85 to user 1. The CO2 reduction operator device 31 is a device for performing the following operations: the CO2 reduction operator 30 receives the CO2 reduction request information 83 and transmits the actual reduction performance value 84 to the service operator device 21.

Refer to Figure 5 The operator device 31 is a device that includes at least a calculation unit 310, a communication unit 313, and a storage unit 314.

For example, the program stored in the ROM is loaded into the RAM and executed on the CPU, thereby realizing the function of the operation unit 310. The communication unit 313 is configured to send and receive Ethernet frames as data generated by the operation unit 310 to the outside via the network 50 which is Ethernet (registered trademark).

[0130] Below, refer to Figure 2 as well as Figure 4 The following describes the functional units included in the calculation unit 210. These functional units are stored in the storage unit 230 and are executed by programs executed by the processor.

[0131] The computing unit 210 includes a usage record receiving unit 211 that receives usage record 81 and user identification information 82 from the user terminal 11. The contents of the usage record 81 and user identification information 82 are as described above. The computing unit 210 also includes a performance storage unit 212 that stores the usage record 81 and user identification information 82 in association with each other. The performance storage unit 212 stores information about which user used the application 110 and to what extent in the storage unit 230 for each user. It should be noted that the service operator device 21 does not necessarily need to include the performance storage unit 212. In this case, a cloud service or external storage medium, for example, may be used to store the usage record 81 and user identification information 82 in association with each other.

[0132] The calculation unit 210 includes a request information creation unit 213 that creates request information 83 for a CO2 reduction operation based on the stored usage records 81. The request information 83 is data containing the CO2 reduction amount requested from the CO2 reduction operator 30, as well as general information such as the requestor and the delivery date. The CO2 reduction amount included in the request information 83 is a value calculated based on the usage records 81. The CO2 reduction amount is calculated, for example, as follows. If the usage records 81 are, for example, the usage time of the application 110, the estimated power consumption is calculated based on the usage time. The CO2 generation amount corresponding to this power consumption is calculated using a predetermined method. The calculated CO2 generation amount may also be used as the requested CO2 reduction amount. In other words, the concept is to determine the energy consumed by the user 1 and the user terminal 11 based on the usage of the application 110, and reduce the amount of CO2 generated by the amount estimated based on this energy. The method for calculating the CO2 reduction amount based on the usage records 81 can be variously specified and is not limited. These calculations can be performed based on predefined mathematical formulas or by referencing a predefined table of numerical relationships stored in storage unit 230. This calculation method is implemented as a function of request information creation unit 213 via a program. It should be noted that the calculation of the requested CO2 reduction amount may also take into account various factors, such as a request from user 1 to purchase additional CO2 reduction amounts, or the acquisition of CO2 reduction amounts in response to events within application 110.

[0133] The timing for creating request information 83 can be arbitrarily determined based on the timing of requesting work from the service operator 20 to the CO2 reduction service operator 30. Request information 83 can include a CO2 reduction amount corresponding to each user's actual usage performance 81 or a CO2 reduction amount corresponding to a total value obtained by summarizing the usage performance 81 of multiple users. The service operator 20 can also create request information 83 including a predetermined CO2 reduction amount regardless of the actual usage performance 81. Alternatively, the service operator 20 can request CO2 reduction work using pre-created request information 83 and obtain the actual reduction performance value 84 at a separate timing.

[0134] The request information transmitting unit 214 transmits the request information 83 to the reduction operator device 31. The reduction value receiving unit 215 receives the actual reduction performance value 84 from the reduction operator device 31. In the CO2 reduction operator 30, CO2 reduction work is performed by operating the CO2 reduction device 32 in accordance with the request information 83. The actual amount of CO2 reduced is stored in the reduction operator device 31 as the actual reduction performance value 84 and transmitted from the reduction operator device 31 to the service operator device 21.

[0135] Below, refer to Figure 5 , the functional units of the calculation unit 310 will be described. These functional units are stored in the storage unit 314 and are executed by programs executed by the processor.

[0136] The calculation unit 310 includes a request information performance receiving unit 311 that receives the CO2 reduction work request information 83 sent from the service operator device 21 . The calculation unit 310 includes a reduction value transmitting unit 312 that transmits the reduction performance value 84 to the service operator device 21 .

[0137] The transmission of information from the service operator device 21 to the reduction operator device 31 and the reception of information from the reduction operator device 31 by the service operator device 21 are performed by the function of the communication unit 220 of the service operator device 21. This transmission and reception is not limited to communication via the Internet by the communication unit 220. For example, instead of communicating via the Internet, the service operator device 21 may output the transmission information created by the request information transmission unit 214 and transmit the output transmission information to the reduction operator device 31 via other means. Alternatively, instead of communicating via the Internet, the reduction value receiving unit 215 may receive information output from the reduction operator device 31 via other input means.

[0138] The calculation unit 210 includes a reduction value transmitting unit 216 that transmits the reduction performance value 84 received from the reduction operator device 31 to the supervisor device 41. The calculation unit 210 also includes a credit receiving unit 217 that receives carbon dioxide credits 85 corresponding to the reduction performance value 84 from the supervisor device 41.

[0139] The timing for transmitting the reduction performance value 84 can be arbitrarily determined. The reduction performance value 84 transmitted may be a value corresponding to each request information 83 or a total value obtained by summarizing values ​​corresponding to request information 83 transmitted a plurality of times.

[0140] The CO2 emission supervisor 40 issues CO2 credits 85 based on the actual reduction performance value 84. The issued CO2 credits 85 are stored in the supervisor device 41 and transmitted from the supervisor device 41 to the service operator device 21.

[0141] The transmission of information from the service operator device 21 to the supervisor device 41 and the reception of information from the supervisor device 41 by the service operator device 21 are performed by the functions of the communication unit 220 of the service operator device 21. This transmission and reception is not limited to communication via the Internet by the communication unit 220. For example, instead of communicating via the Internet, the service operator device 21 may output the transmission information created by the reduction value transmission unit 216 and transmit the output transmission information to the supervisor device 41 via other means. Alternatively, the credit point receiving unit 217 may receive information output from the supervisor device 41 via other input means instead of communicating via the Internet.

[0142] The calculation unit 210 includes a points calculation unit 218 for calculating the contribution points 86 based on the carbon dioxide credits 85 received from the supervisor device 41 and the actual utilization performance 81 of the user 1. As described above, the service operator 20 can define the relationship between the actual utilization performance 81 and the contribution points 86 by various conditions. In other words, it is not excluded that the contribution points 86 may be determined based on conditions other than the actual utilization performance 81. In addition, the calculated contribution points 86 are sent to the user terminal 11 via the points sending unit 219. The contribution points 86 sent from the service operator device 21 are received by the points receiving unit 130 (refer to Figure 3 )take over.

[0143] Through the above process, user 1 can receive contribution points 86 corresponding to actual usage performance 81 of application 110. User 1 can be notified of the acquisition of contribution points 86 by displaying application 110 on user terminal 11. In this embodiment, the amount of carbon dioxide emissions estimated based on the energy consumption associated with user 1's use of application 110 corresponds to the amount of carbon dioxide actually reduced from the atmosphere. As a result, carbon dioxide emissions into the atmosphere are offset, and the user can benefit from the contribution points 86.

[0144] <Second embodiment>

[0145] The second embodiment of the present disclosure is a carbon dioxide reduction promotion system 10 in which a user 1, utilizing an application provided by a service provider 20 on a user terminal 11, obtains carbon dioxide credits 85 corresponding to actual usage performance 81 of the application 110 from a carbon dioxide emission supervisor 40. The following system description uses user 1 as a representative example, but the embodiment includes multiple users, and the number of users is not limited. Furthermore, descriptions that overlap with the first embodiment are omitted.

[0146] Reference Figure 1 as well as Figure 6 Next, the operation of the carbon dioxide reduction promotion system 10 according to the second embodiment of the present disclosure will be described.

[0147] The service operator device 21 receives application usage records 81 and user identification information 82 from the user terminal 11 through communication with the user terminal 11. The usage records 81 are associated with the user identification information 82 of user 1 and stored in the service operator device 21. The service operator device 21 creates request information 83. Request information 83 includes the amount of CO2 reduction work performed according to the usage records 81. The service operator device 21 transmits the created request information 83 to the reduction operator device 31. The service operator device 21 receives from the reduction operator device 31 the reduction performance value 84 associated with the completion of the CO2 reduction work. Based on the usage records 81 of user 1, the service operator device 21 calculates the allocated performance value 87 to be allocated to user 1 from the reduction performance value 84. The service operator device 21 creates data associating the allocated performance value 87 with the user identification information 82. The service operator device 21 transmits the associated data, the allocated performance value 87, with the user identification information 82, to the supervisor device 41. In other words, the data transmitted to the supervisor device 41 is composed of a combination of the user identified by the user identification information 82 and the actual distribution performance value 87 to be allocated to the user. The supervisor device 41 issues CO2 credits 85 corresponding to the reported actual distribution performance value 87. The supervisor device 41 transmits the CO2 credits 85 to the user 1 corresponding to the user terminal 11 to the user terminal 11. The user terminal 11 receives the CO2 credits 85 from the supervisor device 41.

[0148] The above description relates to user 1 and user terminal 11. If there are multiple users, such as user 2, the same applies to each user. If there are multiple users, the request information 83 sent from the service operator device 21 to the reduction operator device 31 can aggregate the requests related to multiple users into a single request.

[0149] (User Terminal)

[0150] The configuration and function of the user terminal 11 in the second embodiment are similar to those of the user terminal 11 in the first embodiment. Figure 3 In the second embodiment, the point receiving unit 130 receives the carbon dioxide credits 85 from the supervisor device 41. That is, the carbon dioxide credits 85 may be received as contribution points 86 instead.

[0151] (Service Operator Device and Reduction Operator Device)

[0152] The service operator device 21 is a device operated by the service operator 20. The service operator device 21 is used to perform the following series of operations: the service operator 20 obtains the actual usage performance 81 of the user 1's application 110, requests the CO2 reduction operator 30 to perform CO2 reduction work corresponding to the actual usage performance 81, compiles the actual reduction performance value 84 into an allocated performance value 87 for each user, and then reports it to the CO2 emission supervisor 40. The configuration and functions of the reduction operator device 31 are the same as those in the first embodiment, and therefore description thereof will be omitted.

[0153] Reference Figure 7 The service provider device 21 is a device that includes at least a computing unit 210, a communication unit 220, and a storage unit 230. The service provider device 21 may also include a general display unit, an input unit, etc., but Figure 7 Illustration omitted. The service operator device 21 can be composed of a computer including a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), a communication interface, an input / output interface, etc. The operation unit 210, the communication unit 220, the storage unit 230, etc. are connected to each other via a bus 240. The storage unit 230 is composed of a volatile or non-volatile storage element, etc. Programs and data are stored in the storage unit 230. For example, the program stored in the ROM is loaded into the RAM and executed on the CPU, thereby realizing the function of the operation unit 210. The communication unit 220 is configured to send and receive data generated by the operation unit 210, etc., such as Ethernet frames, to the outside via the network 50 which is Ethernet (registered trademark).

[0154] Below, refer to Figure 6 as well as Figure 7 The functional units of the calculation unit 210 will be described. These functional units are stored in the storage unit 230 and are executed by programs executed by the processor. Among the functional units of the calculation unit 210, the utilization performance receiving unit 211, the performance storage unit 212, the request information generating unit 213, the request information transmitting unit 214, and the reduction value receiving unit 215 are the same as those in the first embodiment. The description of these functional units will be omitted.

[0155] The calculation unit 210 includes an allocation performance value calculation unit 251 and an allocation performance value transmission unit 252. The allocation performance value calculation unit 251 calculates the amount of carbon dioxide reduction that should be associated with the utilization performance 81 of the user terminal 11 from the reduction performance value 84 received from the reduction operator device 31, and uses this as the allocation performance value 87. The allocation performance value transmission unit 252 transmits the calculated allocation performance value 87 to the supervisor device 41 along with the user identification information 82 that identifies the user terminal 11 associated with the allocation performance value 87.

[0156] The timing for transmitting the distribution performance value 87 can be arbitrarily determined. The distribution performance value 87 to be transmitted may be a value corresponding to each request information 83 or a total value obtained by summarizing values ​​corresponding to a plurality of request information 83 .

[0157] In the CO2 emission supervisor 40, CO2 credits 85 are issued according to the respective distribution performance values ​​87. The issued CO2 credits 85 are stored in the supervisor device 41 and transmitted from the supervisor device 41 to the corresponding user terminal 11.

[0158] The transmission of information from the service operator device 21 to the supervisor device 41 and the receipt of CO2 credits 85 in the user terminal 11 from the supervisor device 41 are not limited to communication via the Internet. For example, instead of communicating via the Internet, the service operator device 21 may output transmission information that organizes data on the user terminal 11 and the distribution performance value 87, and transmit the output transmission information to the supervisor device 41 via other means. Alternatively, the user terminal 11 or the user 1 may receive the CO2 credits 85 output from the supervisor device 41 via other input means, instead of communicating via the Internet.

[0159] Through the above process, user 1 can receive CO2 credits 85 corresponding to actual usage performance 81 of application 110. In this embodiment, the amount of CO2 emissions estimated based on the energy consumption associated with user 1's use of application 110 corresponds to the amount of CO2 actually reduced from the atmosphere. As a result, CO2 emissions into the atmosphere are offset, and the user can receive this contribution in the form of CO2 credits 85.

[0160] The processing of each functional unit in each of the above-mentioned embodiments is implemented by a processing circuit (Circuitry) including one or more processors. The processing circuit can also be composed of an integrated circuit composed of one or more memories, various analog circuits, and various digital circuits on the basis of one or more processors. One or more memories store programs (commands) that enable one or more processors to perform each process. One or more processors can perform each process according to the program read from one or more memories, or can perform each process according to a logic circuit pre-designed to perform each process. The processor can be a CPU (Central Processing Unit), GPU (Graphics Processing Unit: Graphics Processor), DSP (Digital Signal Processor: Digital Signal Processor), FPGA (Field Programmable Gate Array: Field Programmable Gate Array), ASIC (Application Specific Integrated Circuit: Application Specific Integrated Circuit) and other various processors suitable for computer control. It should be noted that multiple physically separated processors can also cooperate with each other to perform each process. For example, the processors installed in each of multiple physically separated computers can cooperate with each other to perform processing via a network such as a LAN (Local Area Network: Local Area Network), a WAN (Wide Area Network: Wide Area Network), and the Internet. The program can be installed into the memory from an external server device via a network, or it can be circulated in a state stored in a recording medium such as a CD-ROM (Compact Disc Read Only Memory), DVD-ROM (Digital Versatile Disk Read Only Memory), or semiconductor memory, and installed into the memory from the recording medium.

[0161] <Carbon Dioxide Reduction Device>

[0162] The following describes the carbon dioxide reduction device 32 used by the carbon dioxide reduction operator 30. This device reduces, captures, and reduces carbon dioxide from the atmosphere, various exhaust gases, and other gases. The carbon dioxide reduction device 32 described in this disclosure is a general term for equipment including carbon dioxide reduction capture devices and their associated equipment, piping, control devices, and power supplies.

[0163] <Capture Device>

[0164] As an example of a capture device, a device that uses a carbon dioxide capture material in a solution to fix carbon dioxide as a capture product and reduce it will be described. The capture device that can be applied to the carbon dioxide reduction promotion system 10 of the present disclosure is not limited to the device described below, and various devices that can separate and reduce carbon dioxide in the gas can be applied. The capture device specifically described below is a device that can reduce and reduce carbon dioxide with a simple structure, and can be applied to the carbon dioxide reduction promotion system 10 of the present disclosure due to the feature of being able to fix and reduce carbon dioxide in the gas as a capture product.

[0165] use Figure 8 and Figure 9 Next, the structure of the capture device 500 will be described. A treatment target gas 512, which is a gas containing carbon dioxide, is supplied to the capture device 500. The carbon dioxide in the treatment target gas 512 is captured in the solution 520 by the action of the carbon dioxide capture material 510.

[0166] The size of the capture device 500 is appropriately set according to the place of use and the purpose.

[0167] The capture device 500 includes a storage tank 501, a carbon dioxide capture material 510, a solution 520 covering the carbon dioxide capture material 510, and a supply unit 530 for supplying a treatment target gas 512 containing carbon dioxide to the solution 520. Carbon dioxide is converted into carbonate ions in the solution 520. The capture device 500 may also include a dissolution promoting mechanism 540 for promoting the dissolution of carbon dioxide into the solution 520, a dispersing mechanism 550 for dispersing a plurality of carbon dioxide capture materials 510 in the solution 520, and a porous support 571 on which the carbon dioxide capture materials 510 are placed. Furthermore, the capture device 500 may also include a solution adjusting mechanism 560 for supplying at least one of an acidic substance, a reducing agent, a metal ion chelating agent, and a detergent to the solution 520.

[0168] (Carbon dioxide capture material)

[0169] The carbon dioxide capture material 510 is in a granular or powdered form. In the present embodiment, the carbon dioxide capture material 510 is a particle having iron or an iron compound as a main component. Examples of the carbon dioxide capture material 510 having iron as a main component are iron and iron alloys. The iron alloy may contain iron and manganese, chromium, molybdenum, aluminum, copper, zinc, nickel, and the like. Examples of iron compounds include iron (II) hydroxide, iron (II) hexacyanoferrate (II), and the like. It should be noted that the carbon dioxide capture material 510 may also be a layered double hydroxide, alkaline metal oxide, or alkaline metal hydroxide other than iron.

[0170] Carbon dioxide capture material 510, which contains iron or an iron compound as its main component, can easily capture carbonate ions and the like in solution 520. Iron ions are generated in solution 520 from the iron and the like in carbon dioxide capture material 510. The carbonate ions and iron ions present in solution 520 are precipitated as iron carbonate and reduced as a capture product.

[0171] The average particle size of the plurality of carbon dioxide capture materials 510 may be, for example, 5 nm to 500 μm, 10 nm to 200 μm, or 15 nm to 100 μm.

[0172] (Supporting Body)

[0173] A plurality of carbon dioxide capture materials 510 are arranged on a support 571. The carbon dioxide capture device 500 includes the support 571, which allows the carbon dioxide capture materials 510 to be stably held. Furthermore, the captured product, which is iron carbonate, adhering to the carbon dioxide capture materials 510 can be easily reduced and cleaned.

[0174] The support body 571 of this embodiment is a porous sheet. A plurality of carbon dioxide capture materials 510 are arranged on a porous sheet. By making the support body 571 a porous sheet, the carbon dioxide capture material 510 can be easily and reliably brought into contact with carbonate ions and the like. In addition, a plurality of carbon dioxide capture materials 510 are arranged at intervals on a porous sheet. By arranging the plurality of carbon dioxide capture materials 510 at intervals, the aggregation of the carbon dioxide capture materials 510 is suppressed, and the capture effect of the carbon dioxide capture materials 510 on carbonate ions and the like is easily improved.

[0175] Support 571 may be, for example, cloth, a nonwoven fabric sheet, a fabric sheet, a sponge sheet, a cellulose fiber sheet such as Japanese paper, a carbon fiber sheet, a ceramic fiber sheet made of, for example, alumina, or a metal fiber sheet made of, for example, copper or stainless steel. Carbon dioxide capture material 510 may be disposed on the surface of support 571 or within support 571. Support 571 is not limited to a porous sheet and may be, for example, porous particles or porous fibers.

[0176] When the capture device 500 includes a plurality of supports 571, the supports 571 may be spaced apart from each other. This configuration allows the plurality of carbon dioxide capture materials 510 to be easily and stably held in a state where they can easily come into contact with carbonate ions and the like.

[0177] When a plurality of support bodies 571 are arranged at intervals from each other, these support bodies 571 may be arranged with spacers 572 interposed therebetween. Figure 8 as well as Figure 9In the embodiment, a plurality of supports 571 are alternately arranged with spacers 572 in the thickness direction thereof. The spacers 572 are, for example, plate-shaped. The spacers 572 are alternately arranged with the supports 571 in a state where their plate surfaces are in contact with the supports 571. The spacers 572 are porous bodies. By making the spacers 572 porous bodies, a passage is formed for carbonate ions and the like to reach the carbon dioxide capture material 510. The spacers 572 are, for example, mesh bodies and sponges. It should be noted that the spacers 572 are not limited to plate-shaped, and may be rod-shaped members that are in contact with only a portion of the supports 571. By having the spacers 572, the plurality of supports 571 can be easily kept apart from each other and arranged at a high density.

[0178] (Supply Department)

[0179] The supply unit 530 supplies the treatment target gas 512, which is a gas containing carbon dioxide, to the solution 520. The supply unit 530 includes, for example, a supply pipe capable of supplying the gas containing carbon dioxide into the storage tank 501 from the lower portion of the storage tank 501.

[0180] (Solution)

[0181] The solution 520 always covers the plurality of carbon dioxide capture materials 510. In the capture device 500, the plurality of carbon dioxide capture materials 510 are immersed in the solution 520.

[0182] The pH of the solution 520 and the potential of the carbon dioxide capture material 510 can be controlled within the range in which divalent iron ions or divalent iron hydroxide are stable in the potential-pH diagram. In other words, the pH of the solution 520 and the potential of the carbon dioxide capture material 510 can be controlled so as to increase the content of divalent iron ions or divalent iron hydroxide in the solution 520.

[0183] The solution 520 contains water as a solvent. In addition, the solution 520 may contain a dissolution promoter that promotes the dissolution of carbon dioxide in the solution 520, and may also contain a pH buffer. In order to reduce the pH of the solution 520, the solution 520 may contain a salt that exhibits acidity in the solution 520. The solution 520 may contain a carbonation promoter 521 for promoting the carbonation of iron ions dissolved from the carbon dioxide capture material 510. The dissolution promoter is, for example, carbonic anhydrase. Carbonic anhydrase promotes the carbonation of bicarbonate ions (HCO3 -) is generated. The pH buffer (Buffer) easily maintains the pH of the solution 520 at a desired value. Examples of pH buffers include sodium tartrate, sodium acetate, sodium borate, sodium citrate, ammonium chloride, and sodium phosphate. Salts that show acidity in the solution 520, that is, salts that dissolve in the solution 520 and show acidity, include sodium bisulfate, ammonium bisulfate, sodium dihydrogen phosphate, iron (II) sulfate, and iron (II) chloride. By making the solution 520 contain salt in this way, the pH of the solution 520 can be easily reduced. In this embodiment, the carbonation promoter 521 is granular. The carbonation promoter 521 has iron carbonate or iron bicarbonate as its main component. The carbonation promoter 521 can become a seed crystal for carbonating iron ions.

[0184] A gas containing carbon dioxide is supplied from the supply unit 530 to the solution 520. As a result, carbonate ions (CO3 2- ) or bicarbonate ion (HCO3 - ).

[0185] (Dissolution promoting mechanism)

[0186] As described above, the dissolution promoting mechanism 540 promotes the dissolution of carbon dioxide in the solution 520. The capture device 500 can easily increase the amount of carbon dioxide in the solution 520 by including the dissolution promoting mechanism 540. Therefore, the efficiency of capturing carbon dioxide is further improved.

[0187] The dissolution promoting mechanism 540 is, for example, a bubble generating device capable of generating microbubbles such as nanobubbles and microbubbles in the solution 520, an ultrasonic generating device capable of generating cavitation bubbles in the solution 520, and a temperature-pressure control device capable of lowering the water temperature of the solution 520 and increasing the partial pressure of carbon dioxide.

[0188] exist Figure 8 as well as Figure 9 In the embodiment, the capture device 500 includes a bubble generator as a dissolution promoting mechanism 540. The bubble generator is disposed in the flow path of the gas containing carbon dioxide from the supply unit 530 to the storage tank 501. The bubble generator converts the gas containing carbon dioxide into fine bubbles and supplies them to the solution 520.

[0189] (Decentralized Organization)

[0190] Dispersion mechanism 550 disperses the plurality of carbon dioxide capture materials 510 in solution 520. Dispersion mechanism 550 maintains the average particle size of the plurality of carbon dioxide capture materials 510. Dispersion mechanism 550 functions particularly effectively when the plurality of carbon dioxide capture materials 510 tend to aggregate. Dispersion mechanism 550 can be a mechanism that generates a water flow in solution 520, such as an ultrasonic generator or a stirring device. Figure 8An ultrasonic generator is shown as the dispersion mechanism 550. Alternatively, a device that uses magnetic force to induce, fractionate, and fix (fix to a specific position) the carbon dioxide capture material 510 may be used as the dispersion mechanism 550. Such a device is, for example, a magnetic separation device.

[0191] (Solution adjustment mechanism)

[0192] The solution adjusting mechanism 560 supplies an acidic substance to the solution 520 when the pH of the solution 520 increases, for example. The acidic substance is, for example, the above-mentioned salt and a solution in which the salt is dissolved.

[0193] (Storage tank)

[0194] A solution 520 is stored in a storage tank 501. The capture device 500 also includes a degassing mechanism 503 for discharging gas released from the solution 520. In this embodiment, the storage tank 501 includes a porous membrane 502 for separating the carbonation promoter 521 from the carbon dioxide capture material 510 and the support 571.

[0195] (Porous membrane)

[0196] like Figure 9 As shown, the porous membrane 502, for example, separates the carbonation promoter 521, the carbon dioxide capture material 510, and the support 571 from one another in the storage tank 501. The carbonation promoter 521 can be positioned below the porous membrane 502, and the carbon dioxide capture material 510 and the support 571 can be positioned above the porous membrane 502. In this way, by separating the carbonation promoter 521 from the carbon dioxide capture material 510 and the support 571 through the porous membrane 502, it is possible to easily reduce iron carbonate, etc., which is a seed crystal of the carbonation promoter 521, as described above.

[0197] The porous membrane 502 can also be configured to suppress the passing through of iron carbonate etc., so that carbonate ion etc. is passed through. By suppressing the passing through of iron carbonate etc. by the porous membrane 502, it is possible to suppress the situation that the iron carbonate etc. of seed are coated on the carbon dioxide capture material 510 with the carbonation promoter 521, so the active reduction of the carbon dioxide capture material 510 can be further suppressed. In addition, by porous membrane 502, carbonate ion etc. is passed through, and it is easy to promote the supply of carbonate ion etc. to the carbon dioxide capture material 510.

[0198] (Degassing promotion mechanism)

[0199] The degassing mechanism 503 is disposed above the storage tank 501. The degassing mechanism 503 discharges gas released from the liquid surface of the solution 520 as it rises within the solution 520, out of the capture device 500. Furthermore, the degassing mechanism 503 discharges the gas out of the capture device 500 to reduce the pressure of the gas in contact with the solution 520. By reducing the pressure of the gas in contact with the solution 520, the degassing mechanism 503 reduces the dissolved oxygen content in the solution 520. This reduces the oxidizing effect of the dissolved oxygen in the solution 520, making it easier to maintain an increased ratio of divalent iron ions in the solution 520.

[0200] It should be noted that the embodiments disclosed herein are illustrative in all respects and are not restrictive. The present invention is not limited to these examples but is defined by the claims, and is intended to encompass all modifications within the meaning and scope of the claims and equivalents thereof.
