Description

Management device, CO2 resource utilization system, and management method

[0001] The present invention relates to a management device, a CO2 resource utilization system, and a management method.

[0002] To mitigate climate change caused by the rapid global warming of recent years, there is a need for reliable CO2 reduction technologies that can ensure sustainability. One such CO2 reduction technology is a CO2 resource conversion system that absorbs CO2 and converts it into valuable materials.

[0003] Various activities are underway to capture CO2 from the atmosphere, primarily through direct air capture (DAC) technology using renewable energy. Furthermore, research and development are becoming increasingly active in the field of carbon dioxide capture and utilization (CCU), which involves either directly utilizing CO2 or converting it into valuable resources, specifically focusing on electrochemical reaction processes using renewable energy. The applicant is working on artificial photosynthesis technology that can reduce CO2 emissions by converting CO2 into valuable resources using electrochemical technology.

[0004] CO2 emissions amount to 1.3 billion tons per year domestically and 26 billion tons per year globally. Industrially, 1 million tons per year are produced domestically, and 150,000 tons per year are used industrially. CO2 derived from CO2 sources, primarily through direct air capture technologies, is increasing, and there are also CO2 products that contribute to CO2 reduction by using renewable energy during production. In recent years, the development of a carbon credit market has progressed, where CO2 is given a price and emissions are bought and sold between companies. Carbon credits, also known as carbon credits, allow companies to sell their surplus emissions when their total emissions fall below the set emission limit.

[0005] Patent Document 1 describes a process for producing butadiene using CO2 as a raw material, in which the flow rate of carbon dioxide is measured and the potential of the electrolytic reduction process in the electrolytic reduction step is controlled based on the flow rate of carbon dioxide.

[0007] Currently, while CO2 storage mechanisms are eligible for carbon credits, there is a problem in that mechanisms for the resource utilization of CO2 are not linked to carbon credits. One reason for this is that it is not possible to quantitatively evaluate the extent to which projects related to the resource utilization of CO2 contribute to CO2 reduction. Furthermore, if the reduction of CO2 from the environment through the resource utilization of CO2 is not recognized as eligible for carbon credits, CO2-derived products, which are valuable materials produced through the resource utilization of CO2, will appear to consumers as expensive products under economic price competition, resulting in low consumer demand and hindering the progress of CO2 utilization. If the origin of CO2 and the conversion rate of CO2 when it is utilized as a resource can be accurately managed and the amount of CO2 reduction can be quantitatively calculated, it is thought that the scale of the environmental economy will expand and CO2 reduction will be promoted if carbon credits can be introduced.

[0008] In order to assign carbon credits to CO2 reduced by a CO2 resource recovery system, proof of the CO2's origin and monitoring to quantify the amount of CO2 reduction are necessary. However, the conventional technology described in Patent Document 1 does not adequately quantify CO2 in the entire system, making it impossible to properly calculate the amount of CO2 reduction. Therefore, it is difficult to generate carbon credits that evaluate the results of CO2 reduction through CO2 resource recovery.

[0009] Therefore, the present invention aims to calculate the CO2 conversion rate necessary to determine the amount of CO2 reduced from the environment by a CO2 resource recovery device, and to accurately calculate the amount of CO2 reduction taking into account the CO2 recovery source.

[0010] To solve the aforementioned problems, the management device of the present invention comprises a memory for storing a program and a processor for executing the program, wherein the processor acquires a CO2 reduction constant, which is an index indicating the degree of CO2 reduction linked to the origin of CO2 recovery, the amount of CO2 supplied to a CO2 resource recovery device that generates products from CO2 using electricity, and the amount of products generated in the CO2 resource recovery device, calculates the CO2 conversion rate of the products based on the amount of CO2 supplied and the amount of products generated, and calculates a first CO2 reduction amount that the CO2 resource recovery device has reduced from the environment using the CO2 based on the CO2 conversion rate, the CO2 reduction constant, and the amount of CO2 supplied.

[0011] The CO2 resource recovery system of the present invention comprises a CO2 resource recovery device that generates products from CO2 supplied from a CO2 recovery system, a memory for storing programs and data, and a processor for executing the program. The processor acquires a CO2 reduction constant, which is an index indicating the degree of CO2 reduction linked to the origin of CO2 recovery, the amount of CO2 supplied to the CO2 resource recovery device that generates products from CO2 using electricity, and the amount of products generated in the CO2 resource recovery device. Based on the amount of CO2 supplied and the amount of products generated, the processor calculates the CO2 conversion rate of the products, and based on the CO2 conversion rate, the CO2 reduction constant, and the amount of CO2 supplied, it calculates a first CO2 reduction amount that the CO2 resource recovery device has reduced from the environment using the CO2.

[0012] The present invention relates to a management method performed by a management device having a memory for storing a program and a processor for executing the program, the method comprising: the processor obtaining a CO2 reduction constant, which is an index indicating the degree of CO2 reduction linked to the origin of CO2 recovery; the amount of CO2 supplied to a CO2 resource recovery device that generates products from CO2 using electricity; and the amount of products generated in the CO2 resource recovery device; and the processor calculating the CO2 conversion rate of the products based on the amount of CO2 supplied and the amount of products generated, and calculating a first CO2 reduction amount achieved by the CO2 resource recovery device using the CO2 based on the CO2 conversion rate, the CO2 reduction constant, and the amount of CO2 supplied. Other means will be described in the embodiments for carrying out the invention.

[0013] According to the present invention, it is possible to accurately calculate the amount of CO2 reduction by the CO2 resource recovery device, taking into account the origin of the CO2 recovery.

[0015] Hereafter, embodiments for carrying out the present invention will be described in detail with reference to the figures. The present invention aims to propose resources with carbon credits using a resource recovery system with certified origin data, utilizing CO2 with CO2 origin data from a CO2 capture system, and to construct an overall CO2 reduction system based on the amount of CO2 reduction, emissions, and resources calculated using the quantitative data that is a component of the resource recovery system.

[0016] This paper presents methods for proving the origin of CO2 used before, after, and during CO2 resource conversion processing. It also outlines monitoring methods and procedures for quantifying the reduced CO2. Furthermore, it presents quantitative management and efficient utilization methods for unused CO2 that could not be converted during the CO2 resource conversion process. In this way, it presents the overall system configuration for CO2 utilization.

[0017] This proposal proposes quantitatively evaluating and digitizing the CO2 involved in CO2 resource recovery systems, where CO2 from various sources is brought in, processed, utilized, and then emitted. While considering the electrical energy used for processing in CO2 resource recovery systems, a system capable of quantitatively evaluating CO2 in a way that allows for verifiable origins related to CO2 emissions for carbon credit conversion has not been considered conventionally.

[0018] This invention aims to achieve carbon credit conversion of CO2 reduced from the environment through a comprehensive system centered on a CO2 resource conversion system aimed at achieving carbon negativity. Carbon negativity refers to the ideal situation where the amount of CO2 reduced from the environment exceeds the amount of CO2 emitted into the environment. As a challenge, this invention proposes a method to prove the origin of CO2 used before, after, and during the CO2 resource conversion process. When using CO2 with CO2 origin data, the CO2 is converted into a resource after being quantified and certified according to its origin in the CO2 recovery system. Quantitative monitoring of CO2 with certified origin is conducted before and after the CO2 resource conversion system. To utilize and monitor certified electricity, the amount of CO2 and emissions during the reaction are monitored, and the use of certifiable emissions and the reaction process are monitored.

[0019] To present the content and methods of monitoring for the quantification of CO2, the monitoring content will include CO2 quantity, electricity consumption, CO2 purity, and other related physical quantities within the system.

[0020] Furthermore, in order to quantitatively manage unused and emitted CO2 that could not be converted during the CO2 utilization process and to propose efficient utilization methods, this paper presents an overall system configuration for CO2 utilization, including the installation of monitoring equipment for unused and emitted CO2, and the recycling and quantification of unused and emitted CO2.

[0021] Figure 1 is a schematic diagram of the CO2 resource recovery system 1 according to the first embodiment. Figure 1 shows the CO2 resource recovery system 1, which includes a CO2 resource recovery device 13, a CO2 recovery system 3, and an energy supply system 2, which is an energy source with energy origin data and quantity data. The CO2 recovery system 3 generates CO2 with CO2 origin data by recovering CO2 from the environment. The CO2 with CO2 origin data generated by the CO2 recovery system 3 is supplied to the CO2 resource recovery device 13. In each drawing, solid arrows indicate matter and energy. Dashed arrows indicate data related to these.

[0022] The CO2 resource utilization system 1 according to this embodiment integrates hardware capable of utilizing CO2 as a resource necessary for creating carbon credits, with software that stores and provides information necessary for the process from approval and issuance to utilization.

[0023] The CO2-derived data attached to the CO2 supplied from the CO2 capture system 3 includes the CO2 capture method, CO2 capture area, CO2 capture equipment, CO2 capture timing, and the amount of CO2 captured. The energy-derived data from the energy supply system 2 includes the amount of energy used or supplied, the type of renewable energy source, the non-fossil energy ratio, and the CO2 emission coefficient designated for the project. These CO2-derived and energy-derived data constitute a dataset composed of multiple data points that allow for quantitative comparison and determination of how much the resource utilization of the CO2 used for energy contributes to CO2 reduction.

[0024] When CO2 is supplied to the CO2 resource recovery device 13, the CO2 is supplied in a state that is distinguished by origin, along with the information of the CO2 origin data. In this embodiment, when it is said that "CO2 origin data is linked," it means that when CO2 is supplied to the CO2 resource recovery device 13 for a predetermined period, the CO2 origin data and the predetermined period during which the CO2 is supplied are managed in combination, and the state in which the CO2 origin data and the supplied CO2 are consistent. Furthermore, when it is said that "CO2 with attached CO2 origin data" or "CO2 with CO2 origin data attached," it refers to CO2 that has been transmitted to the management device 10 with the information of the CO2 origin data attached when the CO2 is supplied, transferred, or transported.

[0025] Figure 2 shows CO2 origin data, which consists of data on the origins of several different types of CO2. Table #1 shows CO2 gas refined from exhaust gases from petrochemical plants as its origin. It includes location data indicating the regional address of the refined plant, company name, and place of manufacture, as well as form information (type data) indicating that the liquid CO2 is in a tank, purity, production date, quantity, and CO2 reduction constant data. The quantity can be expressed as either weight or container volume and pressure. The CO2 reduction constant is a provisional value; for example, reducing the amount of CO2 present in the environment increases the value of the reduction constant. In this case, if the CO2 emissions from the energy used for CO2 reduction are high, the value of the reduction constant decreases. On the other hand, if renewable energy is used for CO2 reduction, the value of the reduction constant increases. Also, when new CO2 is produced, for example, when CO2 is produced from fixed limestone, the reduction constant decreases. This is because it becomes zero as almost no CO2 is reduced. Similarly, Tables #2 to #5 show examples of different origins and variations in CO2 origin data for each type.

[0026] Next, the CO2 resource recovery device 13 converts the CO2 with CO2 origin data into a valuable substance, which is a product, and recovers it as a resource. The management device 10 calculates the CO2 resource origin data necessary to prove the origin of this product. As a result, the CO2 resource recovery system 1 generates a product 14 with CO2 resource origin data. The CO2 resource recovery system 1 provides the product 14 with CO2 resource origin data 14 as a resource to the consumer 4. Here, the consumer 4 is not limited to an individual, but may also be a legal entity such as a company. The CO2 resource recovery device 13 uses energy with energy origin data supplied from the energy supply system 2 to convert the CO2 with CO2 origin data into a valuable substance, which is a product, and recovers it as a resource.

[0027] The management device 10 is composed of an acquisition unit 11, a calculation unit 12, a processor 91, and a memory 93. The memory 93 stores a program. The processor 91 executes the program to realize the acquisition unit 11 and the calculation unit 12, which are described below. The acquisition unit 11 acquires the amount of CO2 linked to CO2 origin data indicating the origin of the CO2 supplied from the CO2 recovery system 3 to the CO2 resource recovery device 13, the composition and amount of products generated in the CO2 resource recovery device 13, and the CO2 reduction target value. For example, the CO2 reduction target value is input by the administrator who manages the CO2 resource recovery system 1.

[0028] The calculation unit 12 calculates the CO2 conversion rate from the amount of CO2 supplied to the CO2 resource recovery device 13 and linked to CO2-derived data, as well as the composition and amount of the products. Based on this, the control device 10 quantifies the amount of CO2 reduced from the environment by the CO2 resource recovery device 13. Regarding this calculation method, the following equations (1) to (11) show the definitions of the parameters and their relationships.

[0029] CO2 emissions for each source of supplied energy are calculated based on the amount of electricity (W) corresponding to the energy source (m). ｍ And the CO2 emissions per unit of electricity for each source are R ｍ This can be calculated based on equation (1).

[0030] The total energy consumption in the CO₂ resource conversion device 13 for each energy source is determined based on Equation (2).

[0031] The CO₂ reduction constant for each energy source is an index indicating the amount of CO₂ relatively reduced according to the type of power generation included in the source information and selected, for example, based on liquefied natural gas power generation, and is determined based on Equation (3). The CO₂ reduction constant for each energy source means an index indicating how much CO₂ can be removed from the environment when the selected energy is used, considering the CO₂ emissions that vary depending on the power generation method.

[0032] The fifth CO₂ reduction amount Z due to energy selection for the entire mixed power when using this standard ｍ＠ is determined based on Equation (4).

[0033] That is, the processor 91 determines the CO₂ reduction amount β for each energy source among the plurality of energies used to generate the product ｍ the power ratio k for each energy source ｍ the power amount W for each energy source ｍ and acquires them. Then, the processor 91 determines the fifth CO₂ reduction amount Z shown in Equation (4) ｍ based on the CO₂ reduction amount β ｍ the power ratio k ｍ and the power amount W ｍ＠ . The fifth CO₂ reduction amount Z ｍ＠ is the reduction amount of CO₂ derived from the energy used. Since the processor 91 can calculate the fifth CO₂ reduction amount Z due to energy selection for the entire mixed power used, it is possible to easily calculate the total CO₂ reduction amount even in countries with different types of reference energy. ｍ＠

[0034] Next, assuming that the name of the source of the supplied CO₂ is n and the CO₂ supply amount for each source is x ｎ the total supply CO₂ amount X to the CO₂ resource conversion device 13 is determined based on Equation (5).

[0035] CO2 conversion rate δ when CO2 from recovered n is converted to product k ｋｎ This can be determined based on equation (6).

[0036] Furthermore, the CO2 conversion rate δ of product k ｋｎ This refers to the utilization rate of CO2 when producing product k using CO2 n derived from recovery. For example, when 100% of CO2 is supplied to the CO2 resource recovery device 13, and 20% of it is used for conversion to product k, the CO2 conversion rate δ of product k is... ｋｎ This accounts for 20%. The remaining 80% consists of other products k ２ It is converted to CO2 or released into the environment. Normally, under the same physical conditions such as temperature and pressure with 100% CO2, the CO2 conversion rate of product k is δ ｋｎ The CO2 conversion rate δ is constant regardless of n. However, the supply process differs depending on the origin of the supplied CO2, and the CO2 conversion rate δ ｋｎ Taking into account the possibility that it may differ, the CO2 conversion rate δ ｋｎ We will consider the case where the data is aggregated as individual data points as the basic approach.

[0037] CO2 reduction constant η for each CO2 source n ｎ Therefore, the first CO2 reduction amount Z achieved by the CO2 resource recovery device, which generates at least one product using at least one recovered CO2 source, is... ｋｎ This can be determined based on equation (7).

[0038] For example, if one product is generated using one source of recovered CO2, u ｋ The result is 1. For example, if product h is produced using CO2 from source f, the first CO2 reduction amount Z is ｆｈ is, (σ ｈｆ η ｆ ・x ｆ This is the result of calculating the CO2 reduction constant η for each CO2 source n. ｎ In other words, it is an indicator of how much CO2 can be reduced from the world when using the selected supply of CO2, taking into account the different CO2 emissions depending on the CO2 capture method.

[0039] The second amount of CO2 reduction Z achieved by the CO2 resource recovery device 13 from the environment through the generation of multiple products using at least one source of recovered CO2. ｋ＠ｎ This can be calculated based on equation (8). For example, if product h and product i are produced using CO2 from source f, the second CO2 reduction amount is Z ｆｈ and Z ｆｉ This is the result of adding them together.

[0040] The third amount of CO2 reduction Z achieved by the CO2 resource recovery device 13 from the environment through the generation of at least one product using CO2 from multiple recovery sources. ｋｎ＠ This can be determined based on equation (9).

[0041] For example, if product h is produced using CO2 from sources f and g, the third CO2 reduction amount is Z ｆｈと Z ｇｈ This is the result of adding them together. For example, if one product is produced using CO2 from multiple recovered sources, u ｋ The result is 1.

[0042] The fourth CO2 reduction amount Z achieved by the CO2 resource recovery device through the generation of multiple products k using CO2 n from multiple recovered sources is the amount of CO2 reduced from the environment. ｋ@ｎ@ This can be determined based on equation (10).

[0043] For example, if product h and product i are produced using CO2 from sources f and g, the fourth CO2 reduction amount is Z ｆｈ Z ｆｉ Z ｇｈ , and Z ｇｉThis is the result of adding the values ​​together. The CO2 utilization product composition ratio refers to the percentage of product k containing the target product among the multiple products produced using CO2. For example, when a mixture is produced from CO2, it contains alcohol and ethylene, and the CO2 utilization product composition ratio refers to the volume ratio of alcohol and ethylene within that mixture. The product composition ratio can be calculated by evaluating the product content measured by sensors 673, 674, 683, and 684, which will be described later.

[0044] Amount of product k produced by CO2 from source n T ｋｎ This value is calculated for each product k by evaluating the content of vaporized products through measurements by sensors 683, 673, etc., as described later. It is determined by equation (11).

[0045] The processor 91 has a CO2 conversion rate δ ｋｎ Based on this, the CO2 resource recovery device 13 reduced a fourth amount of CO2 from the environment, Z, by generating multiple products using CO2 from multiple sources. ｋ＠ｎ＠ The CO2 conversion rate δ of product k due to CO2 from source n is calculated. ｋｎ This can be determined based on equation (12).

[0046] CO2 conversion rate δ of product k from CO2 of origin n ｋｎ This is defined by equation (6) or equation (12), but it is preferable to calculate it using equation (12), which can be calculated using values ​​that can be evaluated during the manufacturing process of the CO2 resource recovery device 13. This makes it possible to calculate the CO2 conversion rate using parameters that can be measured during the manufacturing process.

[0047] The amount of CO2 emitted Q from the CO2 resource recovery device 13 is calculated based on equation (13). The sum of the amount of CO2 emitted Q and the amount of CO2 reused by the CO2 resource recovery device 13 S represents the total amount of CO2 that was not used by the CO2 resource recovery device 13.

[0048] Here, the composition ratio V of the waste ｋThis refers to the CO2 content of the emissions k among the materials generated or emitted during this production process. For example, the composition ratio of the emissions can be calculated by calculating the CO2 concentration using sensors 683 and 684, etc., as described later. The amount of CO2 emitted can also be calculated using sensors 683 and 684, etc.

[0049] Finally, the calculation unit 12 calculates the sixth CO2 reduction amount Z, which is the total amount of CO2 reduction by the CO2 resource recovery device 13. ａｌｌ This is calculated based on equation (14).

[0050] The processor 91 calculates the fourth CO2 reduction amount Z shown in equation (10). ｋ＠ｎ＠ And the fifth CO2 reduction amount Z shown in equation (4) ｍ＠ Based on this, the sixth CO2 reduction amount Z is the total amount of CO2 reduced from the environment by the CO2 resource recovery device 13 using multiple sources of recovered CO2 and multiple energy sources. ａｌｌ This is calculated using equation (14). This allows the control device 10 to accurately calculate the CO2 reduction amount, including the energy used.

[0051] Here, the first CO2 reduction amount Z is achieved by utilizing the CO2 source n as a resource. ｋｎ The first term Z on the right-hand side of equation (14), obtained by summing the amounts of n from the source and k from the product. ｋ＠ｎ＠ This value represents the amount of CO2 reduced from the environment by the CO2 resource recovery device 13, taking into account the different CO2 reduction amounts depending on the CO2 recovery method and the CO2 reduction amount for each product. Also, the second term Z on the right side of equation (14) ｍ＠ This represents the amount of CO2 reduction due to energy selection across the entire mixed power generation, and is the relative amount of CO2 reduction depending on the type of power generation selected, with liquefied natural gas power generation as the baseline. The second term does not need to be calculated. By calculating the second term as well and calculating the total CO2 reduction, it becomes possible to calculate the total reduction while also considering the CO2 reduction due to energy selection.

[0052] CO2 derived data is attached to the CO2 supplied to the CO2 resource recovery device 13. The calculation unit 12 calculates the amount of CO2 reduction from the amount of CO2 supplied with CO2 derived data and the composition and amount of products generated by the CO2 resource recovery device 13. This makes it possible to determine the extent to which CO2 has been reduced throughout the entire system, including the CO2 emitted during the CO2 resource recovery process, and to calculate the amount of CO2 reduction with greater accuracy. Furthermore, it leads to process certification of what kind of CO2 was used for resource recovery.

[0053] The CO2 resource-derived data-attached product 14 is a substance produced from CO2 with CO2-derived data attached, such as CO, methane, methanol, formaldehyde, formic acid, ethylene, ethanol, acetaldehyde, acetic acid, propane, propylene, and propanol. This CO2 resource utilization system 1 can calculate and manage the CO2 conversion rate and CO2 reduction amount from data on the amount of CO2 with CO2-derived data attached used, the composition of the product, and the amount of the product. By considering the CO2-derived data, it becomes possible to accurately evaluate and prove the quality of the CO2 reduced when trading carbon credits.

[0054] Energy supply system 2 is a system that supplies energy to CO2 resource recovery device 13, and for example supplies mixed electricity in the following ratio: oil-fired power generation: hydroelectric power generation: bioethanol fuel power generation: solar energy: hydrogen power generation: wind power generation = 2:2:2:2:1:1. Energy supply system 2 can be adjusted so that the distribution of electricity used over a certain period is specified by contract, etc., and can present a breakdown of the supplied electricity. By monitoring the amount of electricity used for each electricity consumption, the CO2 resource recovery system 1 on the electricity demand side can verify the ratio of electricity from different carbon credit sources used, based on the CO2 reduction constant, which is the contribution rate to CO2 reduction.

[0055] The energy conversion efficiency of coal-fired power plants is 55%. The CO2 emissions per unit of electricity from coal-fired power plants are 943 [gCO2・kWh]. If we denote the origin of coal-fired power plants as c, then the CO2 reduction constant compared to, for example, liquefied natural gas power plants is -469 [gCO2・kWh], as shown in equation (15).

[0061] The energy conversion efficiency of wind power generation is 25%, and the CO2 emissions are 56 [gCO2・kWh].

[0069] 《Example Configuration of CO2 Resource Recovery Device 13》 The method of generating valuable substances from CO2, the types of valuable substances, electrode materials, and solutions are described below. The CO2 resource recovery device 13 is a device that uses electrical energy to generate valuable substances from CO2, that is, to recover resources. -《Method Using Electrical Reactions by Artificial Photosynthesis Technology》 In a cell structure in which electrolyzed water containing dissolved CO2 is separated into two chambers by a diaphragm placed in the middle, anode and cathode electrodes are inserted into each cell, and by passing an electric current from the cathode to the anode, CO2 and H2O decompose and recombine on the surface of the cathode electrode, and C1 organic substances such as methane, methanol, formaldehyde, and formic acid, as well as C2 organic substances such as ethylene, ethanol, acetaldehyde, and acetic acid, and organic compounds with a large number of carbon atoms are generated in the solution, as well as unreacted CO2, H2, CO, O2, CH3, C2H2, and vaporized alcohol as gases.

[0070] It can be manufactured by appropriately adjusting the electrode material (carbon, copper, copper oxide, silver, nickel, iron, palladium, zinc, cobalt, tin, manganese, titanium, platinum, gold, iridium, ruthenium) and structure (single film, multilayer film, porous structure, mesh structure, nanomesh structure film, coated film, cluster structure, impregnating material, powder, granules), electrical conditions, type of electrolytic solution and pH (for example, KCl, NaCl, Na2SO4, KHCO3, Na2CO3, NaHCO3, etc., for example, 2 moles / liter).

[0071] -《Chemical Synthesis》 After desulfurization and reforming of petrochemical exhaust gases, selective CO2 adsorption is carried out by pressure swing adsorption using an appropriate adsorbent. The adsorbed CO2 is separated by changing the pressure conditions, and the extracted CO2 is reacted with H2 gas in a catalytic reactor to convert it into a methanol-water mixture. The reaction purified water produced when methanol is synthesized from CO2 is separated using a zeolite membrane with H2O selective permeability, and methanol is extracted with high efficiency.

[0072] -《Application of electrolysis using catalytic electrodes in solid electrolyte electrode cells》 Figure 3 shows a cell 6 used in a CO2 resource recovery device 13. Cell 6 is composed of an anode electrode 61, an anode cell 62, a diaphragm 63, a cathode cell 64, a cathode electrode 65, and an electrode 69. The anode electrode 61 is located in the anode cell 62. The cathode electrode 65 and electrode 69 are located in the cathode cell 64. The anode cell 62 and the cathode cell 64 are separated by a diaphragm.

[0073] CO2-containing electrolyzed water 661 is injected into the anode cell 62, and waste liquid 671 is discharged. CO2-containing electrolyzed water 662 is injected into the cathode cell 64, and waste liquid 672 is discharged. The amount of CO2-containing electrolyzed water 661 injected is measured by sensor 663. The amount of CO2-containing electrolyzed water 662 injected is measured by sensor 664. In addition, electrolyzed water and CO2 gas are mixed and introduced into the anode cell 62 as CO2-containing electrolyzed water 661, and discharged as waste liquid 671 and exhaust gas 681. In addition, the electrode 69 is made of a porous and water-repellent material, and is a so-called gas diffusion electrode structure in which one electrode surface is in contact with the CO2-containing electrolyzed water 661 in the anode cell 62, and the other electrode surface is in direct contact with the atmosphere or separately introduced CO2 gas.

[0074] The discharge rate of waste liquid 671 is measured by sensor 673. The discharge rate of waste liquid 672 is measured by sensor 674. In exhaust gas 681, sensor 683 evaluates the CO2 concentration and the content of vaporized products such as ethylene and ethanol. Sensor 683 includes a gas flow meter. In exhaust gas 682, sensor 684 evaluates the CO2 concentration and the content of vaporized products such as hydrogen. Sensors 663 and 664 include flow meters. They may also include component CO2 sensors. Sensors 673 and 674 include flow meters. Sensors 663, 673, and 674 may further include a Raman spectrometer, gas chromatography-mass spectroscopy (GC-MS), liquid chromatography-mass spectroscopy (LC-MS), emission spectrometer (ICP), Rutherford backscattering (RBS), and component CO2 sensors.

[0075] The anode electrode 61 and cathode electrode 65 are composed of a film made of a catalyst consisting of a solid electrolyte material such as CsH2PO4 / SiP2O7. These anode electrode 61 and cathode electrode 65 are heated to 200-250°C, exposed to a mixed gas of CO2 and H2O, and an electric current is passed through them. This causes a reaction to proceed on the surfaces of the anode electrode 61 and cathode electrode 65, generating valuable substances. The resulting substance changes depending on the combination of catalysts.

[0076] Figure 4 is a schematic diagram of a modified CO2 resource recovery system 1. Figure 4 shows a CO2 resource recovery device 13 and the CO2 resource recovery system 1 including it, a CO2 recovery system 3, and an energy supply system 2 which is an energy source with energy origin data.

[0077] The CO2 with CO2 origin data, suitably generated in the CO2 recovery system 3, is supplied to the CO2 resource recovery device 13 of the CO2 resource recovery system 1. Next, the CO2 resource recovery system 1 converts the CO2 with CO2 origin data into a valuable substance, the product, in the CO2 resource recovery device 13. Then, the management device 10 calculates the CO2 resource origin data necessary for the origin. As a result, the CO2 resource recovery system 1 produces the product 14 with CO2 resource origin data.

[0078] The CO2 resource-derived data calculated by the calculation unit 12 of the management device 10 includes, in addition to the CO2 recovery method, CO2 recovery area, CO2 recovery equipment, and CO2 recovery time included in the CO2-derived data, the amount of CO2 used in the product, the product generation method, the product manufacturing equipment, and the product manufacturing time.

[0079] The CO2 resource recovery system 1 discharges CO2-containing emissions to the emission destination 5. The CO2 resource recovery system 1, using a management device 10, adds CO2 emission origin data and CO2 emission data to the CO2-containing emissions discharged from the CO2 resource recovery system 1. The CO2 resource recovery system 1 then notifies the emission destination 5 of the CO2 emission origin data and CO2 emission data. The management device 10 further adds the CO2 emission origin data to the CO2 resource origin data-attached product 14 and provides it to the consumer 4.

[0080] The CO2 emission-derived data calculated by the calculation unit 12 of the control device 10 includes the amount of CO2 corresponding to the emission, the emission method, the equipment used for emission, and the timing of emission.

[0081] Here, the processor 91 calculates the sixth CO2 reduction amount Z as shown in equation (23). ａｌｌ From this, the amount of CO2 emissions Q contained in the emissions is subtracted to calculate the seventh CO2 reduction P removed from the environment by the CO2 resource recovery device 13.

[0082] The management device 10 also adds CO2 emission origin data and data on the composition and quantity of the monitored emissions and products to the emissions from the CO2 resource recovery device 13. The acquisition unit 11 further acquires the composition and quantity of emissions that are discharged as by-products of the products produced by the CO2 resource recovery device 13 and that are linked to CO2 emission origin data. The calculation unit 12 further calculates the amount of CO2 reduction from the amount of CO2 supplied to the CO2 resource recovery device 13 and linked to CO2 origin data, the composition and quantity of products linked to CO2 resource origin data, and the composition and quantity of emissions linked to CO2 emission origin data. Specifically, the CO2 emission amount Q measured by sensors 683 and 684 is used to calculate the sixth CO2 reduction amount Z, which is the sum of the CO2 reduction amounts calculated using equation (12). ａｌｌBy subtracting from this, the seventh CO2 reduction amount is calculated. This makes it possible to calculate and manage CO2 reductions that also take into account the amount of CO2 emitted. By considering CO2 emission-derived data, it becomes possible to accurately evaluate and prove the quality of the reduced CO2 when trading carbon credits. Furthermore, the CO2 resource conversion system 1 provides the product 14 with CO2 resource-derived data as a resource to the consumer 4.

[0083] The CO2 resource utilization system 1 adds data on the composition and quantity of the products and provides the products with CO2 resource origin data to consumers 4 as resources. Examples of CO2 resource origin data products 14 include CO, methane, methanol, formaldehyde, formic acid, ethylene, ethanol, acetaldehyde, acetic acid, propane, propylene, and propanol.

[0084] The CO2 resource recovery system 1 calculates the CO2 conversion rate from the amount of CO2 supplied to the CO2 resource recovery device 13 and linked to CO2-derived data, as well as the composition and amount of products linked to CO2 resource-derived data. Furthermore, by adding the amount of products linked to CO2 resource-derived data and the amount of CO2 reduced by selecting energy linked to energy-derived data, and then subtracting the amount of emissions linked to CO2 emission-derived data from this value, it is possible to calculate and manage the total CO2 reduction amount for the entire CO2 resource recovery system 1.

[0085] Figure 5 shows the monitoring points of the CO2 resource recovery system 1. Monitoring point 301 is where the CO2 supplied by the CO2 capture system 3 to the CO2 resource recovery system 1 is monitored. Monitoring of the amount of CO2 is necessary for each process such as capture, sequestration, utilization, emission, and reuse, so monitoring is performed at the connection point.

[0086] For CO2 measurements at monitoring point 301, if pure gas is guaranteed, measurement data such as gas flow rate, gas pressure, and usage time may suffice. For mixtures, verify the gas and liquid composition and measure the CO2 partial pressure. Detailed measurements should be obtained by appropriately utilizing GCMS, LCMS, other mass spectrometry, fluorescence analysis methods, etc., to determine the composition and evaluate whether there are any sequential changes in the composition. If stable, measure the CO2 partial pressure using a CO2 gas sensor, etc. If unstable, select an evaluation method appropriate to the composition and monitor it.

[0087] Monitoring point 201 is where the energy supplied by the energy supply system 2 to the CO2 resource recovery system 1 is monitored. At monitoring point 201, the total amount of electricity consumed is measured using a power meter. The CO2 resource recovery system 1 then saves a log of the measurement data and stores logs of energy source data, including electricity-derived data and the amount of electricity for each electricity-derived source, based on the contract or from the power company. The stored energy source data is used by the management device 10 to calculate the individual CO2 consumption associated with electricity.

[0088] Monitoring point 1301 is where the products recovered by the CO2 resource recovery device 13 are monitored. At monitoring point 1301, the recovered liquid and gaseous substances are periodically monitored using highly accurate measurement methods, such as gas chromatography, liquid chromatography, and Raman chromatograph. For continuous monitoring after obtaining accurate evaluation values ​​and composition data, a gas sensor, which is a simple evaluation method with numerical calibration for specific substances such as CO2, is selected, and the measurement results are monitored sequentially, accumulating data logs.

[0089] Monitoring point 101 is a point for monitoring the products that the CO2 resource recovery system 1 has recovered and provided to consumers 4. Monitoring point 102 is a point for monitoring the emissions that the CO2 resource recovery system 1 has emitted to the emission destination 5.

[0090] 《Acquired Data Content》 Electricity may be supplied from a single power source or composed of a mix of different power sources. In either case, the ratio is publicly disclosed by the power company, or it is possible to have such a contract. With such a contract, the receiving side can monitor the amount of electricity and calculate the individual CO2 consumption associated with electricity for each monitored mechanism, process, equipment, or device. Alternatively, it is possible to collect certified power consumption logs from the equipment used in each process, ensure there is no duplication, and use the aggregated data as the monitoring value.

[0091] 《Time-series data》 In cases where the type of electricity used changes depending on the time of day in each process and mechanism, such as with solar power utilization, this may affect the calculation of CO2 emissions. Therefore, the management device 10 maintains hourly usage log data. Even when considering a system with a mix of energy types and fluctuating type selections, the accumulation of data acquired by this system makes it possible to appropriately calculate electricity usage with energy-derived data, as well as CO2 consumption and reduction.

[0092] 《CO2 Amount Data》 The data on the amount of CO2 measured by the CO2 sensor, along with the associated origin data, is presented in the form of data measuring the amount input, the amount recycled / utilized, the amount emitted, and the amount recovered, each with its respective origin data attached.

[0093] 《Composition and Quantity of Products and Emissions》 The products obtained by converting CO2 are mixtures of various substances. Therefore, the compositional distribution of the products in each state is quantitatively evaluated using mass spectrometry techniques such as gas chromatography, liquid chromatography, and inductively coupled plasma mass spectrometry. The composition and content ratio of these products are then obtained as data, along with data on the CO2 resource origin. Valuable materials and resources are monitored separately as resource quantities, and the CO2 contained in emissions is also monitored on a regular basis. These are quantified, recovered, and reused as appropriate. Unused CO2 and unreacted, unused, and by-generated CO2 are included in emissions. These are recovered and reused while quantitatively monitoring them, along with data on CO2 emission origin and data on unused emission CO2 origin.

[0094] The management device 10 is an information processing device that calculates CO2 emissions. It manages the power supply side, including power suppliers, power generators, transmission companies, and grid management companies, as well as the energy of CO2 conversion operators, equipment, and devices.

[0095] The control devices 10 work in conjunction with each other to take action when power fluctuations occur, and to control the overall operation of the production line when CO2 emissions fluctuate, in order to maintain the CO2 emission target. Data retention is long-term archiving, assuming that the data will be traceable as energy-derived data.

[0096] The control device 10 manages energy consumption, recovered CO2 amount, composition and weight of emissions, and composition and weight of resources and products. Energy consumption is measured by measuring electrical energy with a power meter and measuring the composition and weight of fuel.

[0097] The control device 10 mechanically evaluates the amount of recovered CO2 using flow meters, pressure gauges, and weighing scales, measures it using gas chromatography and CO2 sensors as purity confirmation monitors, and also measures it using optical measurements, discharge spectroscopy, and sampling analysis.

[0098] The control device 10 measures the composition, weight, and volume of the waste by X-ray fluorescence analysis and inductively coupled plasma mass spectrometry for metal composition analysis. The control device 10 also analyzes the amount of resources and products by X-ray fluorescence analysis and inductively coupled plasma mass spectrometry, and measures the weight and quantity of the products.

[0099] Figures 6A and 6B are flowcharts of the operations performed by the control device 10. Initially, the control device 10 receives inputs of total energy consumption, recovery source name, CO2 reduction constant and CO2 emissions per unit energy for each recovery source, energy efficiency, and energy consumption ratio (step S10).

[0100] The control device 10 calculates the amount of CO2 reduction per unit of electricity for each recovery source from the CO2 reduction constant for each recovery source (step S11). Then, the control device 10 adds the amount of CO2 reduction per unit of electricity for each recovery source according to the types of electricity included in the mixed electricity to calculate the amount of CO2 reduction per unit of electricity for the mixed electricity (step S12).

[0101] Next, the management device 10 calculates the amount of CO2 reduction per unit of electricity for each source of renewable energy electricity, according to the types of electricity included in the mixed renewable electricity (step S13). Then, based on the amount of CO2 sensed at monitoring points 301, 1301, and 102, the management device 10 calculates the CO2 conversion rate of the products, the amount of CO2 recovered as resources, the amount for each product, the amount of CO2 emitted, and the amount of reuse (step S15). The CO2 conversion rate of the products is obtained by dividing the amount of CO2 measured at monitoring point 1301 by the amount of CO2 measured at monitoring point 301.

[0102] Furthermore, based on the results sensed at monitoring points 1301 and 102, the management device 10 calculates the product composition ratio and the emission composition ratio, which are the composition ratios of the products after CO2 resource recovery (step S16), calculates the amount of CO2 reduction for each type of recovered product or manufactured product (step S17), and calculates the total amount of CO2 reduction for the entire utilization (step S18).

[0103] Subsequently, the control device 10 determines whether the amount of CO2 reduction calculated in step S18 is equal to or greater than the target value acquired by the acquisition unit 11 (step S19). If the amount of CO2 reduction is equal to or greater than the target value (Yes), the process proceeds to step S20, and the consumer 4 consumes the generated resources and ends the process shown in Figure 6A. If the amount of CO2 reduction is less than the target value (No), the process proceeds to step S21.

[0104] In step S21, the control device 10 determines whether the reduction constant can be increased. If the reduction index can be increased (Yes), the process proceeds to step S22. If the control device 10 increases the proportion of those with large reduction constants (Step S22), the process returns to step S11. If the reduction constant cannot be increased (No), the process proceeds to step S23. Increasing the reduction constant can be done by referring to energy-derived data and selecting, for example, energy with a high reduction constant from among the energy types. Alternatively, it can be done by referring to CO2-derived data and selecting CO2 with a high reduction constant from among the CO2 to be supplied.

[0105] In step S23, the control device 10 determines whether the total amount of CO2 emissions can be reduced. If the total amount of CO2 emissions can be reduced (Yes), the process proceeds to step S24. If the control device 10 reduces the total amount of CO2 emissions (Step S24), the process returns to step S11. If the total amount of CO2 emissions cannot be reduced (No), the process proceeds to step S25. The total amount of CO2 emissions is calculated by adding the amount of CO2 emitted from the power generation of energy used in the energy supply system 2, the amount of CO2 contained in the emissions from the CO2 resource recovery device 13, and referring to energy-derived data and CO2 emission-derived data.

[0106] In step S25, the control device 10 determines whether the amount of CCS (Carbon dioxide Capture and Storage) can be increased. If the amount of CCS can be increased (Yes), the process proceeds to step S26. When the control device 10 increases the amount of CCS, the process returns to step S11. If the amount of CCS cannot be increased (No), the process shown in Figure 6B ends. The amount of CCS refers to the sum of the amount of CO2 stored in the CO2 recovery system 3 and the amount of CO2 used to produce products in the CO2 resource recovery device 13.

[0107] Figure 7 is a schematic configuration diagram of the CO2 resource recovery system 1 with the addition of a productization device 15 according to the second embodiment. Figure 7 shows the CO2 resource recovery system 1 including the CO2 resource recovery device 13 and the productization device 15, the CO2 recovery system 3, and the energy supply system 2 which is an energy source with energy origin data.

[0108] CO2 generated in the CO2 capture system 3 and with proven origin data is supplied to the CO2 resource recovery system 1, which includes the CO2 resource recovery device 13.

[0109] Next, the CO2 resource recovery device 13 of the CO2 resource recovery system 1 converts the CO2 with CO2 origin data into a valuable substance, which is then used as a resource. The management device 10 calculates the CO2 resource origin data necessary for origin certification and adds it to the product of the CO2 resource recovery device 13 to create a CO2 resource origin data-attached product 14. Furthermore, the management device 10 may also calculate CO2 emission origin data and add it to the CO2 resource origin data-attached product 14.

[0110] The product manufacturing device 15 uses the recycled CO2 resource-derived product 14 with data attached to it to manufacture a product. The acquisition unit 11 acquires the composition and quantity of the product manufactured by the product manufacturing device 15. The calculation unit 12 calculates product-derived data by adding the product manufacturing method, product manufacturing region, product manufacturing equipment, product manufacturing period, product composition, and quantity to the various data included in the CO2 resource-derived data. The product manufacturing device 15 adds the product-derived data to the manufactured product to create a product with product-derived data attached 17.

[0111] Furthermore, the calculation unit 12 calculates the CO2 conversion rate from the amount of CO2 linked to CO2-derived data supplied to the CO2 resource recovery device 13, the composition and amount of the product 14 with CO2 resource-derived data, and the composition and amount of the product 17 with product-derived data linked to the product. In addition, when calculating the CO2 conversion rate, the composition and amount of emissions linked to CO2 emission-derived data may also be included.

[0112] The productization apparatus 15 provides consumers 4 with products that include CO2 resource-derived data-attached products 14, purified and diluted products of the CO2 resource-derived data-attached products 14, or mixtures or reaction products in which the ratios of different materials contained in the CO2 resource-derived data-attached products 14 are adjusted, and these are sealed and packaged in appropriate containers for sale. The productization apparatus 15 may also calculate CO2 emission-derived data and generate product-derived data-attached products 17, which are products to which CO2 emission-derived data is attached.

[0113] The control device 10 also adds CO2-derived data and data on the composition and quantity of the monitored emissions and products to the emissions from the CO2 resource recovery device 13. As a result, the CO2 resource recovery system 1 processes the products 14 with CO2 resource-derived data as resources and provides and consumes them as products 17 with product-derived data.

[0114] Products 17 with product origin data include, for example, CO, methane, methanol, formaldehyde, formic acid, ethylene, ethanol, acetaldehyde, acetic acid, propane, propylene, and propanol. Products 17 with product origin data also include purified and diluted versions of these substances. Products 17 with product origin data also include mixtures of different materials contained in these CO2 resource-derived product 14, mixed in adjusted ratios, or products produced by reaction. Products 17 with product origin data are sealed and packaged in appropriate containers for sale. The CO2 resource utilization system 1 can calculate and manage the CO2 conversion rate and CO2 reduction amount from the amount used to convert CO2 with CO2 origin data into products and CO2 emission data.

[0115] Figure 8 is a schematic diagram of the CO2 resource recovery system 1 with the addition of a productization device 15 according to the third embodiment. Figure 8 shows the CO2 resource recovery system 1 including the CO2 resource recovery device 13 and the productization device 15, the CO2 recovery system 3, and the energy supply system 2 which is an energy source with energy origin data.

[0116] The CO2 capture system 3 generates CO2 with CO2 origin data and supplies it to the CO2 resource recovery system 1, which includes the CO2 resource recovery device 13. The CO2 resource recovery device 13 of the CO2 resource recovery system 1 converts the CO2 into valuable substances for resource recovery. The management device 10 calculates the CO2 resource origin data and CO2 emission origin data necessary for origin certification and adds this to the valuable substances to create a CO2 resource origin data-attached product 14. Next, the CO2 resource origin data-attached product 14 is sent to the product development device 15 along with the product origin data. Furthermore, the product development device 15 uses this resource-recovered product to manufacture products and adds product origin data and CO2 emission origin data to create a product with product origin data 17. At this time, the management device 10 calculates the product origin data necessary for origin certification. Finally, the CO2 resource recovery system 1 provides the CO2 resource origin data-attached product 14 and the product origin data-attached product 17 using it to the consumer 4.

[0117] Based on the energy source with energy-derived data supplied by the energy supply system 2 to the productization device 15, and the product 14 with CO2 resource-derived data, the control device 10 adds CO2 emission-derived data and data on the composition and quantity of monitored emissions and products to the emissions from the productization device 15. The productization device 15 manufactures products 17 with product-derived data and provides them to consumers 4.

[0118] According to this CO2 resource utilization system 1, it is possible to calculate and manage the CO2 conversion rate and CO2 reduction amount from the CO2 emission data of the CO2 used and the CO2 emission data of the emissions, including the product manufacturing process by the product manufacturing device 15. In other words, the CO2 conversion rate and CO2 reduction amount for the entire system can be calculated by also considering the CO2 emission data and CO2 emission data of the emissions from the product manufacturing device 15.

[0119] Figure 9 is a schematic configuration diagram of the CO2 resource recovery system 1 with an added overall control device 7 according to the fourth embodiment. Figure 9 shows the CO2 resource recovery system 1 including the CO2 resource recovery device 13, the CO2 recovery system 3, the energy supply system 2 which is an energy source with energy origin data, and the product processing device 15. CO2 with CO2 origin data, which is generated in the CO2 recovery system 3 and whose origin has been verified, is supplied to the CO2 resource recovery system 1 including the CO2 resource recovery device 13.

[0120] The CO2 resource recovery device 13 of the CO2 resource recovery system 1 converts CO2 with CO2 origin data into valuable substances for resource recovery. The management device 10 calculates the CO2 resource origin data and CO2 emission origin data necessary for proof of origin, generates a product 14 with CO2 resource origin data, adds CO2 emission origin data, and provides the consumer 4 with a product using the product 14 with CO2 resource origin data. Furthermore, a product development device 15 may be provided to create a product 17 with product origin data using the product 14 with CO2 resource origin data and provide it to the consumer 4.

[0121] The management device 10 adds CO2-derived data, energy-derived data, and data on the composition and quantity of monitored emissions to the emissions after CO2 resource conversion, and provides the consumer 4 with the CO2 resource-derived data product 14. The management device 10 may further provide the consumer 4 with the product-derived data product 17.

[0122] The overall control device 7 can calculate and manage the CO2 conversion rate and CO2 reduction amount for the entire related CO2 resource utilization system 1, based on the CO2 usage amount with individual CO2-derived data for each of the related CO2 resource utilization systems 1, and the energy and CO2 emission data with energy-derived data.

[0123] Figure 10 is a configuration diagram reflecting the energy origin data of the electricity used by the CO2 capture system 3. The CO2 capture system 3 is composed of a capture origin unit 31 and a CO2 origin data assignment unit 32. The capture origin unit 31 stores capture origin data for the captured CO2, including energy origin data of the energy required for capture and generation. The CO2 origin data assignment unit 32 associates the captured CO2 with CO2 origin data indicating the origin of this CO2. As a result, the CO2 resource utilization system 1 generates valuable materials with CO2 origin data attached using CO2 with CO2 origin data attached, and utilizes them as resources.

[0124] The CO2 resource recovery system 1 adds CO2 emission origin data and data on the composition and quantity of the emissions during CO2 resource recovery, generating CO2 emission origin data and CO2 resource origin data-attached product 14. The CO2 resource recovery system 1 can calculate and manage the CO2 conversion rate and CO2 reduction amount from the amount of CO2 used with CO2 origin data-attached CO2 and the CO2 emission origin data. By adding origin data to the CO2 supplied to the CO2 resource recovery device 13 using data including energy origin data from the CO2 recovery system 3, it becomes possible to accurately calculate the amount of CO2 reduction corresponding to the emissions during CO2 resource recovery.

[0125] Figure 11 is a schematic diagram of a CO2 resource recovery system 1 with an added unused CO2 recovery device 16 according to the fifth embodiment. Figure 11 shows a CO2 resource recovery system 1 including a CO2 resource recovery device 13 and an unused CO2 recovery device 16, a CO2 recovery system 3, and an energy supply system 2 which is an energy source with energy origin data.

[0126] The CO2 resource recovery system 1 receives CO2 with CO2 origin data based on energy with energy origin data, and generates CO2 resource-derived products 14 with CO2 resource origin data. Unused CO2 emissions and other emissions after the CO2 resource recovery device 13 has utilized the CO2 are sent to the unused CO2 recovery device 16 along with unused emission origin data. Unused emission origin data is data indicating the origin of the unused CO2 emissions discharged from the CO2 resource recovery device 13 to the unused CO2 recovery device 16.

[0127] The unused CO2 recovery device 16 recovers CO2 from a mixture of unused CO2 and other emissions after the CO2 resource recovery device 13 has utilized the CO2. The recovered CO2 is then given data on its origin and quantity, and returned to the CO2 resource recovery device 13. The reuse origin data is data indicating the origin of the recovered CO2 that is recovered by the unused CO2 recovery device 16 and returned to the CO2 resource recovery device 13.

[0128] Furthermore, the unused CO2 capture device 16 adds final CO2 emission origin data to the CO2-separated emissions and discharges them to the destination 5. The CO2 resource recovery system 1 provides the product 14 with CO2 resource origin data to the consumer 4. This makes it possible to reuse the CO2 contained in the emissions of the CO2 resource recovery device 13, thereby increasing the amount of CO2 reduction.

[0129] The acquisition unit 11 acquires the amount of recovered CO2 linked to reuse-derived data, which is supplied from the unused CO2 emission recovery device 16 to the CO2 resource recovery device 13. The calculation unit 12 calculates the CO2 conversion rate from the amount of CO2 linked to CO2-derived data and reuse-derived data supplied to the CO2 resource recovery device 13, the composition and amount of the products, the composition and amount of the emissions linked to CO2 emission-derived data, and the amount of recovered CO2 linked to reuse-derived data, which indicates the origin of the recovered CO2 returned from the unused CO2 emission recovery device 16 to the CO2 resource recovery device 13.

[0130] The CO2 resource recovery system 1 can calculate and manage the CO2 conversion rate and CO2 reduction amount from data on CO2 usage linked to CO2 origin data and reuse origin data, the amount of unused CO2 emitted by the CO2 resource recovery device 13, and the amount of CO2 recovered by the unused CO2 recovery device 16.

[0131] Figure 12 is a schematic diagram of a CO2 resource recovery system 1 with an added unused CO2 recovery device 16 according to the sixth embodiment. Figure 12 shows a CO2 resource recovery system 1 including a CO2 resource recovery device 13 and an unused CO2 recovery device 16, a CO2 recovery system 3, and an energy supply system 2 which is an energy source with energy origin data. The CO2 resource recovery system 1 is supplied with CO2 with CO2 origin data including energy, and generates a CO2 resource origin data product 14.
