Description

[Technical Field]

[0001] Embodiments of the present invention relate to a CO2 resource utilization promotion device, a CO2 reduction and regeneration system, and a CO2 resource utilization promotion method. [Background technology]

[0002] Addressing global warming is a globally recognized challenge. Countries are expanding their renewable energy-based electricity supply to achieve this goal. Furthermore, surplus renewable energy is being used to electrolyze water and produce hydrogen (green hydrogen). Carbon recycling is also progressing, involving the separation and capture of carbon dioxide (CO2), the electrolysis of the captured CO2 to produce carbon monoxide (CO), and the creation of chemical products along with green hydrogen.

[0003] Figure 8 is a conceptual diagram showing an example of carbon recycling using a CO2 reduction and regeneration device.

[0004] CO2 from exhaust gases generated at CO2-generating facilities (original emitters) and CO2 in the atmosphere are separated and recovered at CO2 separation and recovery facilities. The separated and recovered CO2 is electrolytically reduced in a CO2 reduction and regeneration device, and further chemical products are produced. Specifically, in the CO2 reduction and regeneration device, CO is first reduced to CO in a CO2 electrolytic cell using electricity derived from renewable energy. The generated CO, along with green hydrogen produced by electrolysis in a separate electrolytic cell using electricity derived from renewable energy, becomes a raw material for synthesis in a synthesis facility, and chemical products are produced. In addition, jet fuel (SAF), diesel fuel, fibers, plastics, etc. are produced using the chemical products produced in the CO2 reduction and regeneration device as raw materials.

[0005] In particular, a significant portion of the CO2 released into the atmosphere by the combustion of SAF is absorbed by forests, but the remaining CO2 is recovered and separated again, thus forming a carbon recycling cycle. [Prior art documents] [Patent Documents]

[0007] Currently, the prevailing policy regarding CO2 emissions in carbon recycling is that the original emitter bears all responsibility. As a result, there is no incentive for original emitters to build carbon recycling systems. On the other hand, while secondary users of CO2 do not bear responsibility or burden for emissions, they need to procure CO2 from original emitters who do not provide incentives. Against this backdrop, the flow of CO2 as a resource is shrinking, and there is a concern that the carbon recycling cycle will not function adequately, or even break down altogether.

[0008] The problem that this invention aims to solve is to provide a CO2 resource utilization promotion device and a CO2 resource utilization promotion method that promote carbon recycling. [Means for solving the problem]

[0009] To achieve the above-mentioned objectives, the CO2 resource utilization promotion device according to this embodiment is CO 2 The waste disposal facility supplies CO2 reduction and regeneration equipment that accepts CO2, generates CO through electrolytic reduction using electricity from renewable energy sources, and produces chemical products through chemical synthesis. By building a carbon recycling system A CO2 resource utilization promotion device that promotes the utilization of CO2 resources, The aforementioneda contracting unit that determines conditions including a contracted price for purchasing CO2 emission credits in a CO2 emission credit trading market with a CO2 emission facility; an information acquisition unit that acquires information of the CO2 emission credit trading market; a purchase determination unit that determines whether the CO2 emission credits in the name of the CO2 emission facility are purchased and outputs an instruction for the purchase; and an emission credit delivery unit that delivers the purchased CO2 emission credits to the CO2 emission facility.

[0011] Hereinafter, with reference to the drawings, a CO2 resource recycling promotion device, a CO2 reduction regeneration system, and a CO2 resource recycling promotion method according to an embodiment of the present invention will be described. Here, common reference numerals are given to portions that are identical or similar to each other, and overlapping descriptions are omitted. Note that carbon dioxide (CO2) may be referred to as CO2 for convenience.

[0012] [First Embodiment] FIG. 1 is a block diagram showing the relationship in carbon recycling of the CO2 resource recycling promotion device 100 of the CO2 reduction regeneration system 10 according to the first embodiment.

[0013] The CO2 reduction regeneration system 10 includes a CO2 reduction regeneration device 10a and a CO2 resource recycling promotion device 100. The CO2 reduction regeneration device 10a includes a CO2 electrolysis device 11 and a chemical synthesis device 12.

[0014] The gas containing CO2 discharged from the CO2 emission facility 20 is converted into high-purity CO2 by the CO2 separation and recovery device 25. Note that even when the CO2 separation and recovery device 25 is not provided, CO2 may be recovered by other means. Further, the operator of the CO2 reduction regeneration system 10 may own the CO2 separation and recovery device 25.

[0015] The CO2 reduction regeneration system 10 receives the recovered CO2. Since receiving CO2 is a CO2 treatment service, the system receives payment for the processing service. Details of the processing service fee will be described later with reference to FIG. 3.

[0016] The CO2 electrolysis device 11 of the CO2 reduction regeneration system 10 reduces CO2 to generate CO using electric power supplied from a renewable energy device 13 such as wind power or solar power, for example. Here, the renewable energy device 13 may be owned by the operator of the CO2 reduction regeneration system 10, or may be owned by another operator. Since the generated CO is produced using renewable energy, it is green CO.

[0017] Furthermore, although this may be owned by the operator of the CO2 reduction and regeneration system 10 or by another operator, the H2O electrolytic device 14 uses electricity from the renewable energy device 13 to reduce H2O and produce hydrogen (H2). Since the produced H2 is from renewable energy, it is green hydrogen.

[0018] The chemical synthesis apparatus 12 of the CO2 reduction and regeneration system 10 produces various chemical products using green CO generated by the CO2 electrolysis apparatus 11 and green hydrogen generated by the H2O electrolysis apparatus 14 as raw materials.

[0019] The operator of the CO2 reduction and regeneration system 10 sells various chemical products generated by the chemical synthesis device 12 to the demand facility 30, but may also sell the green CO itself generated by the CO2 electrolysis device 11 to the demand facility 30 in the process.

[0020] The CO2 resource utilization promotion device 100 promotes CO2 resource utilization through the exchange of information with the CO2 electrolysis device 11, the chemical synthesis device 12, the CO2 emission facility 20, and the emissions trading market 40. The details will be explained with reference to Figures 2 and 3.

[0021] As stated above, when referring to the CO2 reduction and regeneration system 10, the CO2 emission facility 20, and the demand facility 30, the terms should include not only the facilities themselves but also the businesses that own them. For example, when referring to the CO2 emission facility 20, it should also mean the original emitter that uses the CO2 emission facility 20 to conduct business and emit CO2. Similarly, when referring to the emissions trading market 40, it should include not only the market itself but also the businesses that operate the market.

[0022] Figure 2 is a block diagram showing the configuration of a CO2 resource recovery promotion device according to the first embodiment.

[0023] The CO2 resource utilization promotion device 100 includes an information acquisition unit 111, a calculation unit 120, a storage unit 130, an output unit 140, a contract unit 150, an emission allowance purchase unit 160, and an emission allowance delivery unit 170. The CO2 resource utilization promotion device 100 is, for example, a computer system, but it may also be a collection of individual devices and equipment each having the function of its respective element.

[0024] The information acquisition unit 111 acquires price information for CO2 emission allowances in the emissions trading market 40 on a case-by-case basis. The information acquisition unit 111 also acquires information such as the CO2 emissions from the CO2 emission facility 20 to the extent possible.

[0025] The calculation unit 120 includes a contract setting unit 121, a profit calculation unit 122, and a purchase determination unit 123.

[0026] The contract setting unit 121 sets or changes conditions (emission allowance purchase conditions) such as the purchase price from the emissions trading market 40 for the CO2 emissions and the associated CO2 emission allowances to be agreed upon with the CO2 emission facility 20 (contract price Pc [yen / kgCO2]), and the purchase quantity M [kg].

[0027] The profit calculation unit 122 calculates the purchase profit G1 associated with the purchase of CO2 emission allowances from the emissions trading market 40. Here, the purchase profit G1 [yen] is given by the following equation (1). G1 = (Pc - Pt) × M - Cf ... (1) Here, Pt[kg] is the purchase price [yen / kgCO2] when actually purchased from the emissions trading market 40, and Cf[yen] is the fees and expenses associated with purchasing CO2 emission allowances from the emissions trading market 40.

[0028] The purchase determination unit 123 determines whether or not to purchase based on the amount of purchase profit G1 [yen] calculated by the profit calculation unit 122. The determination may be made, for example, if the following equation (2) is true, then purchase is made. G1 / M≧g min ...(2) Here, g min The value of [yen / kgCO2] may depend on the value of M.

[0029] The memory unit 130 includes a contract information memory unit 131, an emission allowance memory unit 132, and a profit memory unit 133.

[0030] The contract information storage unit 131 stores the terms and conditions for purchasing emission allowances agreed upon with the CO2 emission facility 20.

[0031] The emission allowance storage unit 132 stores, for each CO2 emission facility 20, the purchase history of CO2 emission allowances and information regarding emission allowances N agreed upon before purchase.

[0032] The profit storage unit 133 stores the results calculated by the profit calculation unit 122.

[0033] The output unit 140 displays the information acquired by the information acquisition unit 111 and the information stored in the storage unit 130. The output unit 140 may also function as a human interface, for example, by allowing input from a screen and displaying information upon request.

[0034] The contracting unit 150 exchanges information with the CO2 emission facility 20 and determines the conditions for purchasing emission allowances.

[0035] The emission allowance purchase unit 160 purchases CO2 emission allowances from the emission allowance trading market 40 if the purchase determination unit 123 determines that a purchase is appropriate. In this case, the CO2 emission allowances are in the name of the CO2 emission facility 20, which is the counterparty to the agreement, and this is clearly stated in the certificate issued by the emission allowance trading market 40.

[0036] Alternatively, the administrator or other relevant party may purchase CO2 emission credits without establishing an emission credit purchase department 160.

[0037] The emission allowance transfer unit 170 transfers the purchased CO2 emission allowances to the CO2 emission facility 20. Specifically, it sends the certificate issued by the emission allowance trading market 40 to the CO2 emission facility 20. In this case, if the certificate is in the form of an electronic certificate, it may also be transmitted electronically to the CO2 emission facility 20.

[0038] Figure 3 is a flowchart showing the procedure for the CO2 resource utilization promotion method according to the first embodiment.

[0039] Figure 3 shows, from left to right, the operations of the emissions trading market 40, the CO2 emission facilities 20, the CO2 resource utilization promotion device 100 and other devices of the CO2 reduction and regeneration system 10, and the demand facilities 30, as well as the flow of goods and information between them. The flow of goods is shown with thick white arrows, and the flow of information is shown with arrows. In Figure 3, the flow of time and the order of operations are shown from top to bottom.

[0040] First, the contract setting unit 121 of the CO2 resource utilization promotion device 100 creates a draft contract condition based on the emission allowance purchase condition 1, and the contract unit 150 presents this emission allowance purchase condition 1 to the CO2 emission facility 20 (step S11).

[0041] Upon receiving the emission allowance purchase conditions 1, the CO2 emission facility 20 presents emission allowance purchase conditions 2 to the contract section 150 of the CO2 resource recovery promotion device 100 (step S12).

[0042] The contracting unit 150 compares emission allowance purchase condition 2 with emission allowance purchase condition 1 and determines whether they match or if any differences are within an acceptable range, i.e., whether the condition is met (step S13).

[0043] If the contract unit 150 does not determine that the contract has been concluded (step S13 NO), steps S11 to S13 are repeated.

[0044] If the contracting unit 150 determines that the agreement is concluded (step S13 NO), the contracting unit 150 enters into an agreement with the CO2 emission facility 20 regarding the terms of purchasing emission allowances (step S14).

[0045] The above outlines the steps related to the agreement between the CO2 resource utilization promotion device 100 and the CO2 emission facility 20.

[0046] Once an agreement is reached regarding the purchase of emission allowances, the flow of goods begins. The following describes the sequence of goods flow.

[0047] First, the CO2 emission facility 20 ships CO2 to the CO2 reduction and regeneration system 10 (step S01), and the CO2 reduction and regeneration system 10 receives this CO2 (step S02).

[0048] In the CO2 reduction and regeneration system 10, green CO is generated by the electrolysis of CO2 by the CO2 electrolyzer 11 (step S03), and chemical products are further generated by synthesis in the chemical synthesis apparatus 12 (step S04). In addition, the demand facility 30 purchases the CO generated in step S03 (step S04) and the chemical products generated in step S05 (step S06). Furthermore, the demander makes payment for the chemical products (step S07), and the CO2 reduction and regeneration system receives payment (step S08).

[0049] The above describes the flow of goods after the agreement between the CO2 resource utilization promotion device 100 and the CO2 emission facility 20, specifically the CO2 reduction and regeneration system 10.

[0050] Next, we will explain the flow of information after the agreement between the CO2 resource utilization promotion device 100 and the CO2 emission facility 20.

[0051] First, the information acquisition unit 111 continuously acquires information from the emissions trading market 40 (step S21). The information from the emissions trading market 40 includes, in particular, the market price of CO2 emission allowances and its changes over time.

[0052] The profit calculation unit 122 calculates the purchase profit G1 associated with the purchase of CO2 emission rights from the emissions trading market 40. Here, the purchase profit G1 [yen] is given by the following equation (3). G1 = (Pc - Pt) × M - Cf ... (3) Here, Pt[kg] is the purchase price [yen / kgCO2] when actually purchased from the emissions trading market 40, and Cf[yen] is the fees and expenses associated with purchasing CO2 emission allowances from the emissions trading market 40.

[0053] The purchase determination unit 123 determines whether or not to make a purchase based on the amount of the purchase profit G1 [yen] calculated by the profit calculation unit 122. The determination is made, for example, if the following equation (4) is true, that is, (G1 / M) is g min If the above conditions are met, you may decide to purchase the item. G1 / M≧g min ...(4) Here, g min The value of [yen / kgCO2] may depend on the value of M.

[0054] If the purchase determination unit 123 does not determine that a purchase is possible (step S22 NO), then steps S21 and S22 are continued.

[0055] If the purchase determination unit 123 determines that a purchase is necessary (step S22 YES), the emission allowance purchase unit 160 purchases CO2 emission allowances from the emission allowance trading market 40 (step S23). The purchase transaction between the emission allowance purchase unit 160 and the emission allowance trading market 40 is conducted online.

[0056] The emissions trading market 40 receives purchase application information from the emissions purchasing department 160 (step S24) and issues emissions certificates in the name of the CO2 emission facility 20 (step S25). During this time, the payment for the purchase of CO2 emissions is made online from the emissions purchasing department 160 to the emissions trading market 40.

[0057] The emission allowance purchase unit 160 receives the emission allowance certificate sent as electronic data online (step S26). The emission allowance delivery unit 170 delivers the emission allowance certificate received as electronic data by the emission allowance purchase unit 160 (step S27). In other words, it sends the emission allowance certificate as electronic data to the CO2 emission facility 20. The CO2 emission facility 20 receives the emission allowance certificate sent as electronic data (step S28).

[0058] Furthermore, the issuance of emission allowance certificates from the emission allowance trading market 40 to the emission allowance purchasing unit 160, and the delivery of emission allowance certificates from the emission allowance delivery unit 170 to the CO2 emission facility 20, may be done in the form of physical certificates rather than electronic data.

[0059] According to this embodiment, the CO2 emission facility 20 (original emitter) can automatically receive emission credit certificates for the CO2 by requesting the CO2 reduction and regeneration system 10 to process the CO2. In other words, it can obtain CO2 emission credits (CO2 credits) for the amount of CO2 it requests the CO2 reduction and regeneration system 10 to process, and offset that amount against its CO2 emissions. Obtaining such CO2 credits provides an incentive for the original emitter (CO2 emission facility 20) to request the CO2 reduction and regeneration system 10 to process the CO2. Furthermore, it allows the CO2 reduction and regeneration system 10 to more reliably secure its source of CO2.

[0060] As a result, the process of converting CO2 into a resource will accelerate, strengthening the carbon recycling cycle.

[0061] [Second Embodiment] Figure 4 is a block diagram showing the configuration of the CO2 resource recovery promotion device 100a according to the second embodiment.

[0062] This embodiment is a modification of the first embodiment, in which the CO2 resource utilization promotion device 100a further includes a rebate benefit granting unit 180, and the calculation unit 120a further includes a rebate benefit calculation unit 124, and the storage unit 130a further includes an external input storage unit 134. In addition, the calculation unit 120 has a profit calculation unit 122a instead of the profit calculation unit 122 in the first embodiment. In other respects, it is the same as the first embodiment. The differences from the first embodiment will be described below.

[0063] In this embodiment, in addition to the delivery of emission rights certificates to the original emitter (CO2 emission facility 20) as in the first embodiment, the CO2 reduction and regeneration system 10 returns to the CO2 emission facility 20 a portion of the profits it obtains from the CO2 it receives from the CO2 emission facility 20.

[0064] Here, the CO2 reduction and regeneration system 10 can obtain the following three types of benefits:

[0065] (1) The first is the emissions trading profit G1 [yen] calculated by the profit calculation unit 122 in the first embodiment. That is, it is the profit from purchasing CO2 credits in the name of the original emitter from the emissions trading market 40.

[0066] (2) The second is the acceptance profit G2 [yen] from the CO2 emission facility 20 for the purpose of treating the CO2 generated by the CO2 emission facility 20.

[0067] (3) The third is the sales profit G3 [yen] from the sale of green CO2 and green chemical products generated by the CO2 reduction and regeneration system 10.

[0068] The first emission allowance purchase profit G1 [yen] is calculated by the profit calculation unit 122a in the same manner as in the first embodiment. The profit calculation unit 122a further calculates the second receipt profit G2 [yen] and the third sales profit G3 [yen].

[0069] The calculated emission allowance purchase profit G1 [yen], receipt profit G2 [yen], and sales profit G3 [yen] are stored in the profit storage unit 133.

[0070] The profit Gr [yen] returned to the original emitter (CO2 emission facility 20) may be Gr1 [yen], which is part of the profit G1 from purchasing emission rights as described in (1) above; or it may be Gr2 [yen], which is part of the profit G2 from receiving emissions as described in (2) above; or it may be Gr3 [yen], which is part of the profit G3 from sales as described in (3) above. The CO2 reduction and regeneration system 10 selects one of these options in advance.

[0071] Note that these three cases (reduction level 1 is only (1), reduction level 2 is (1)+(2), and reduction level 3 is (1)+(2)+(3)) may be selected according to the original emitter (CO2 emission facility 20). For example, if stable acceptance from the original emitter is possible in the future, or if the purity of the accepted CO2 is high, the reduction level may be increased. Note that reduction profit Gr2 and reduction profit Gr3 may be positioned as investments for promoting CO2 recycling.

[0072] The reduction level and each reduction profit Gr described later j Parameters for calculating [yen] (j=1 to 3) are received as external inputs by the external input receiving unit 112, and stored and saved in the external input storage unit 134.

[0073] Hereinafter, the calculation content performed by the reduction profit calculation unit 124 for each profit will be described. The results calculated by the reduction profit calculation unit 124 are stored and saved in the profit storage unit 133.

[0074] FIG. 5 is a graph illustrating the first reduction profit Gr1 obtained by the reduction profit calculation unit 124 of the CO2 recycling promotion apparatus 100a according to the second embodiment. The horizontal axis represents emission right purchase profit G1 [yen], and the vertical axis represents various profits [yen].

[0075] Straight line A is a straight line that gives the same value as the horizontal axis when the slope is 1. That is, straight line A is the value of the emission right purchase profit G1 [yen].

[0076] The external input receiving unit 112 receives the fixed profit G 10 [yen] and the reduction rate r1 as external inputs. The external input storage unit 134 stores and saves these pieces of information.

[0077] The reduction profit calculation unit 124 calculates the reduction profit Gr1 [yen] by the following equation (5). Gr1=(G1-G 10 )×r1···(5) Here, the reduction rate r1 is obtained by subtracting the fixed profit G from the purchase profit G1 10The value G obtained by subtracting 11 This is the ratio of the return on investment Gr1 to the total return.

[0078] Fixed profit G 10 The value of [yen] can be zero. Also, the reduction rate r1 relates to the purchase of CO2 emission allowances from the emissions trading market 40, so if it is split equally with the original emitter, for example, it will be 0.5.

[0079] Figure 6 is a graph illustrating the second reduction profit Gr2 calculated by the reduction profit calculation unit 124 of the CO2 resource utilization promotion device 100a according to the second embodiment.

[0080] Line B is a line that gives the same value as the horizontal axis with a slope of 1. In other words, line B represents the value of the profit received G2 [yen].

[0081] The external input receiving unit 112 receives fixed profit G 20 The system accepts the currency (yen) and the return rate r2 as external inputs. The external input storage unit 134 stores and stores this information.

[0082] The capitalization profit calculation unit 124 calculates the capitalization profit Gr2 [yen] using the following formula (6). Gr2=(G2-G 20 ) × r2···(6) Here, the return rate r2 is calculated by subtracting the fixed profit G from the received profit G2. 20 The value G obtained by subtracting 21 This is the ratio of the capitalization profit Gr2 to the fixed profit G. 20 The value of [yen] may be zero.

[0083] The same method can be used to derive the third sales profit G3 [yen] as to the capitalization profit Gr2 [yen]. Therefore, the explanation is omitted.

[0084] Figure 7 is a flowchart showing the procedure for the CO2 resource utilization promotion method according to the second embodiment. Below, only the parts added to the first embodiment will be described.

[0085] First, the profit calculation unit 122a further calculates the received profit G2 [yen] and the sales profit G3 [yen], and then calculates the return profit for each (step S31). In detail, the process is as follows: When CO2 is shipped from the CO2 emission facility 20 (step S01) and CO2 is received by the CO2 reduction and regeneration system 10 (step S02), payment for the received CO2 is exchanged. In addition, when a consumer purchases chemical products (step S06), the consumer pays the price (step S07), and the CO2 reduction and regeneration system receives the payment (step S08). Based on these details, the profit calculation unit 122a calculates the received profit G2 [yen] and the sales profit G3 [yen], respectively. The calculated results are stored in the profit storage unit 133.

[0086] The rebate granting unit 180 grants the original emitter a rebate of Grj in the form of electronic information, based on the information stored in the benefit storage unit 133, according to the rebate level (step S32). The CO2 emitting facility 20 (original emitter) receives the rebate (step S33).

[0087] Thus, in this embodiment, the original emitter (CO2 emission facility 20) can acquire a portion of the profits earned by the CO2 reduction and regeneration system 10, further motivating them to request CO2 treatment from the CO2 reduction and regeneration system 10. Furthermore, the CO2 reduction and regeneration system 10 can more reliably secure its source of CO2.

[0088] As a result, the process of converting CO2 into a resource will be further accelerated, strengthening the carbon recycling cycle.

[0089] According to the embodiments described above, it is possible to provide a CO2 resource utilization promotion device and a CO2 resource utilization promotion method that promote carbon recycling.
