This is a functional configuration diagram showing an example of the functions provided by the raw material information management system according to the fifth embodiment of this disclosure.

[0011] [First Embodiment] Below, a raw material information management system 1, a raw material information management method, and a raw material information management program according to the first embodiment of this disclosure will be described with reference to the drawings.

[0012] Figure 1 shows the network configuration of the raw material information management system 1 according to this embodiment. As shown in Figure 1, the raw material information management system 1 is connected via network 3 to a user terminal 70 used by a manufacturing plant 10 (see Figure 2) that manufactures fuel or chemical products, and is configured to send and receive information to and from each other. The raw material information management system 1 is also connected via network 3 to power plant operator terminals 80 (80a to 80c) of a power plant, and is configured to send and receive information to and from each other.

[0013] Figure 1 illustrates one user terminal 70 and three power generation operator terminals 80, but the number of these connected to the raw material information management system 1 is not limited to this example. In the following, when it is necessary to distinguish between power generation operator terminals 80a, 80b, etc., they will be referred to as power generation operator terminals 80a and 80b, respectively, and when it is not necessary to distinguish between them, they will simply be referred to as power generation operator terminal 80.

[0014] As described above, the user terminal 70 is an information processing device used by a business operator that operates a manufacturing plant 10 that produces fuel (synthetic fuel) or chemical products. The manufacturing plant 10 may be a plant that produces both fuel and chemical products. An example of fuel is carbon-neutral fuel such as SAF (Sustainable Aviation Fuel). An example of chemical products is low-environmental-impact chemical products such as blue hydrogen, blue ammonia, and blue methanol.

[0015] The user terminal 70 may also be a management server that manages various control data of the manufacturing plant 10. The operator of the fuel manufacturing plant is provided with an account and password, and the system is configured to allow access to the raw material information management system 1 from each user terminal 70 using this login information.

[0016] The power generation operator terminal 80 is, for example, an information processing device used by a business operator that operates a power plant supplying renewable energy. The power generation operator terminal 80 may also be a management server that manages various control data of the power plant. Power generation operator terminal 80a is a terminal used by the operator of power plant A (for example, a solar power plant), power generation operator terminal 80b is a terminal used by the operator of power plant B (for example, a wind power plant), and power generation operator terminal 80c is a terminal used by the operator of power plant C (for example, a hydroelectric power plant).

[0017] The raw material information management system 1 may be connected to an administrator terminal (not shown), and may be configured to allow data input and management from the administrator terminal. The administrator terminal is, for example, an information processing device used by the operating company of the raw material information management system 1. The system operating company may have an administrator account and password, and may be able to access the raw material information management system 1 from the administrator terminal using this login information.

[0018] Figure 2 shows an example configuration of a manufacturing plant. The manufacturing plant 10 shown in Figure 2 is a fuel manufacturing system that produces SAF, and includes, for example, a hydrolysis unit 11, a thermal power plant 12, a CO reverse shift reactor 13, a water electrolysis unit 14, an SOEC co-electrolysis unit 15, a hydrogen gas generator 16, and an FT synthesis unit 17.

[0019] The thermal power plant 12 is equipped with a gasifier. The gasifier uses oxygen gas and steam as gasifying agents to produce a product gas containing hydrogen and carbon monoxide from biomass raw materials. It also generates electricity using the combustible gas produced in the gasifier. Examples of biomass raw materials used include wood chips, wood pellets, thinned wood, waste wood, driftwood, bark, paper sludge, municipal solid waste, and agricultural residues. Municipal solid waste and agricultural residues are hydrolyzed in a hydrolysis unit 11, for example, and then supplied to the gasifier.

[0020] The CO reverse shift reactor 13 produces CO by reducing CO2 with H2 (reverse shift reaction). For example, the CO reverse shift reactor 13 produces CO by reducing CO2 emitted from a thermal power plant 12 with H2. The water electrolysis unit 14 produces hydrogen gas by electrolyzing water, for example. The SOEC co-electrolysis unit 15 produces H2 and CO by electrolyzing recovered CO2 recovered by a CO2 recovery unit, etc., and water vapor (H2O), for example. The hydrogen gas generator 16 produces hydrogen gas from waste cooking oil, etc. The FT synthesis unit 17 uses CO supplied from the CO reverse shift reactor 13, H2 supplied from the water electrolysis unit 14, the SOEC co-electrolysis unit 15, the hydrogen gas generator 16, etc., to react CO and H2 using the FT (Fischer-Tropsch) method (FT synthesis reaction) to produce synthetic fuel (e.g., SAF).

[0021] The configuration of the manufacturing plant 10 shown in Figure 2 is just one example and is not limited thereto. In other words, any configuration is acceptable as long as it is a plant that produces synthetic fuels and chemical products. Furthermore, some of the equipment in the manufacturing plant 10 shown in Figure 2 (for example, the water electrolysis unit 14) can also constitute the manufacturing plant 10.

[0022] As shown in Figure 2, electricity, CO2, water, etc. (hereinafter referred to as "raw materials") are used when manufacturing synthetic fuels or chemical products in the manufacturing plant 10. In order for the final fuel or chemical product to be certified as carbon neutral, these raw materials (electricity, CO2, water, etc.) used in the manufacturing process must also meet prescribed standards.

[0023] The raw material information management system 1 manages and guarantees the origin of these raw materials (especially electricity) used in the manufacturing plant 10, along with time information.

[0024] Figure 3 is a schematic diagram showing an example of the hardware configuration of the raw material information management system 1. The raw material information management system 1 is a so-called server (computer), and as shown in Figure 3 as an example, its main components include a CPU (processor) 31, an auxiliary storage device 32 for storing programs executed by the CPU 31 (for example, a CO2 trading program), a main memory 33 that functions as a work area when each program is executed, and a communication device 34 for connecting to a network. These components are connected via a bus 38. The raw material information management system 1 may further include an input unit 35 such as a keyboard and a display unit 36. The auxiliary storage device 32 stores, for example, an OS for controlling the entire raw material information management system 1, various drivers for hardware operation of peripheral devices, applications for realizing the raw material information management system 1, and various data and files. Examples of the auxiliary storage device 32 include semiconductor memory, magnetic disks, magneto-optical disks, etc.

[0025] The user terminal 70 and the power generation operator terminal 80 are, for example, desktop PCs, notebook PCs, tablet PCs, tablet terminals, mobile phone terminals, smartphones, servers, etc. Since the configuration of the user terminal 70 and the power generation operator terminal 80 is publicly known, a detailed explanation will be omitted, but like the raw material information management system 1 described above, they are equipped with a CPU, auxiliary storage device, main memory, communication device, input unit, etc. The auxiliary storage device stores, for example, an OS for controlling the user terminal 70 and the power generation operator terminal 80, various drivers for hardware operation of peripheral devices, applications for realizing the functions of the user terminal 70 and the power generation operator terminal 80 described later, and various data and files.

[0026] Next, the functions of the raw material information management system 1 according to this embodiment will be described. Figure 4 is a functional configuration diagram showing an example of the functions provided by the raw material information management system 1 according to this embodiment. A series of processes for realizing each of the functions described below are stored as a program (for example, a raw material management program) in the auxiliary storage device 32 of the raw material information management system 1, and the CPU 31 reads this program into the main memory 33 and executes it to realize various functions. The program may be provided in a form that is pre-installed in the auxiliary storage device 32 of the raw material information management system 1, in a form that is stored in a computer-readable storage medium, or in a form that is distributed via wired or wireless communication means. Computer-readable storage mediums include magnetic disks, magneto-optical disks, CD-ROMs, DVD-ROMs, semiconductor memory, etc.

[0027] As shown in Figure 4, the raw material information management system 1 includes a raw material detailed information acquisition unit 41, a power supply information acquisition unit 42, a determination unit 43, an output unit 44, and the like. The raw material information management system 1 may also include a raw material detailed information database 45 for storing raw material detailed information, a power supply information database 46 for storing power supply information, and a standard information database 47 for storing various standard information.

[0028] The raw material information management system 1 may include a screen data creation unit (not shown) that creates various screen data to be displayed on the user terminal 70 in accordance with various information received from the user terminal 70 and the power generation operator terminal 80, and a storage unit (not shown) that stores various information exchanged between the user terminal 70 and the power generation operator terminal 80.

[0029] The raw material details acquisition unit 41 acquires raw material details, including power usage information related to the electricity used in the manufacture of fuel or chemical products. The raw material details acquisition unit 41 acquires this information, for example, by receiving raw material details from the user terminal 70. The power usage information includes, for example, power usage time (in other words, time information, for example, from XX / XX / XX / XX XX:XX to △△ / △△ / △△ / XX:XX), amount of power used, and information related to the power receiving system. For example, taking the manufacturing plant 10 shown in Figure 2 as an example, raw material details including power usage information related to the electricity used in the CO reverse shift reactor 13 and the water electrolysis unit 14 are acquired from the user terminal 70. When the raw material details acquisition unit 41 acquires raw material details including power usage information from the user terminal 70, it stores this information in the raw material details database 45.

[0030] The power supply information acquisition unit 42 acquires power supply information related to renewable energy generated by each power plant A to C. The power supply information acquisition unit 42 acquires this information, for example, by receiving power supply information from each power generator terminal 80a to 80c. The power supply information includes power generation time, power generation amount, and information related to the power distribution system. Once the power supply information acquisition unit 42 acquires power supply information from each power generator terminal 80a to 80c, it stores this information in the power supply information database 46.

[0031] The determination unit 43 determines whether the electricity used in the manufacture of fuel or chemical products is renewable energy by comparing the electricity usage information with the electricity supply information of each power plant A to C.

[0032] More specifically, the power plant that supplies electricity is identified from the power receiving system included in the power usage information and the power distribution system included in each power supply information. Then, it is determined whether the identified power plant generated more electricity than was used during the power usage time period included in the power usage information. As a result, if the power plant that supplies electricity generated more renewable energy than was used and supplied it to the distribution system, it is determined that the electricity is derived from renewable energy.

[0033] By making such a determination, it becomes possible to confirm and guarantee that electricity is being generated at the power plant during the time the manufacturing plant is using electricity, that the power distribution system of the power plant is connected to the power receiving system of the manufacturing plant, and that the renewable energy generated at the power plant is being supplied to the manufacturing plant. The determination unit 43 stores the determination result in the raw material details database 45 in association with the raw material details. The determination unit 43 may also compare the raw material details with various regulation data stored in the regulation information database 47 to determine whether the raw materials used in the manufacture of synthetic fuels or chemical products meet the regulations. For example, one example of a regulation is various regulations related to Life Cycle Assessment (LCA).

[0034] The output unit 44 outputs the determination result. For example, the output unit 44 transmits the raw material details data, which is linked to the raw material details and the determination result, to the user terminal 70. In this case, if the determination result is that the product was manufactured using renewable energy, the output unit 44 may create certificate data indicating that fact and transmit the certificate data linked to the raw material details data to the user terminal 70. Furthermore, if the determination unit 43 determines that the raw material details meet the requirements, the output unit 44 may generate certificate data indicating that the requirements are met and transmit it linked to the raw material details data to the user terminal 70.

[0035] Next, the raw material information management method according to this embodiment will be described with reference to the drawings. The series of processes shown below are stored as a program (for example, a raw material information management program) in the auxiliary storage device 32 of the raw material information management system 1, and are realized when the CPU 31 reads this program into the main memory 33 and executes it. Figure 5 is a flowchart showing an example of the processing procedure for the CO2 trading method according to this embodiment. The flowchart shown in Figure 5 is executed repeatedly at predetermined timings.

[0036] First, for example, in each manufacturing plant, electricity usage is acquired from electricity meters installed in each piece of equipment within the plant at predetermined intervals (e.g., every 10 minutes, every hour, every day, etc.), and electricity usage information is created that associates the electricity usage amount, the period of electricity usage, and the power receiving system. Then, this electricity usage information is transmitted to the raw material information management system 1 via the user terminal 70 (SA1). The process of creating the electricity usage information may be performed on the user terminal 70, or it may be performed on the management server that manages the manufacturing plant.

[0037] The raw material information management system 1 obtains raw material details from the user terminal 70 (SA2) and stores the obtained raw material details in the raw material details database 45.

[0038] At each power plant A to C, power supply information regarding power generation time, power generation amount, and distribution system is created, and this power supply information is transmitted to the raw material information management system 1 via power plant operator terminals 80a to 80c (SA3). The power supply information creation process may be performed at power plant operator terminal 80, or it may be performed at each management server or control system that manages the various power plants A to C.

[0039] The raw material information management system 1 acquires power supply information from each power generation operator terminal 80a to 80c (SA4) and stores the acquired power supply information in the power supply information database 46.

[0040] The raw material information management system 1 determines whether the electricity used in the manufacture of fuel or chemical products is renewable energy by comparing the acquired electricity usage information with the electricity supply information (SA5). The raw material information management system 1 stores the determination result in the raw material details database 45, associating it with the raw material details.

[0041] The raw material information management system 1 transmits raw material detailed data in which the raw material detailed information and the determination result are associated to the user terminal 70 (SA6). Also, at this time, when the raw material information management system 1 obtains a determination result that the production was performed using renewable energy, it may create certificate data indicating the same, associate the certificate data with the raw material detailed data, and transmit it to the user terminal 70. The user terminal 70 receives and acquires the raw material detailed data and the like transmitted from the raw material information management system 1 (SA7).

[0042] According to this embodiment, the following operational effects are achieved. It becomes possible to easily prove whether the electric power used in the production of fuel or chemical products is renewable energy. Thereby, it becomes possible to guarantee whether fuel or chemical products were produced using clean energy. Also, by issuing the certificate data, it becomes possible to use it for applications for various subsidies and the like.

[0043] Also, by associating the raw material detailed information including the power usage information with the determination result, it is possible to grasp at which time zone the fuel or chemical product produced is a fuel or chemical product derived from renewable energy. Thereby, it is possible to distinguish between the fuel or chemical product produced using renewable energy and the fuel or chemical product produced using non-renewable energy. As a result, by distinguishing the produced fuel or chemical products and storing them in individual tanks, it becomes possible to continuously operate the plant. As a result, it is possible to avoid a decrease in the operating rate of the plant.

[0044] In this embodiment, the raw material information management system 1 may further acquire the power supply plan of renewable energy in each of the power generation plants A to C. In this case, the raw material information management system 1 may predict the future producible amount of fuel or chemical products based on the plurality of raw material detailed data stored in the raw material detailed information database 45 and the power supply plan in the power generation plant.

[0045] [Second Embodiment] Next, a raw material information management system 1 according to the second embodiment of this disclosure will be described. In the raw material information management system 1 according to this embodiment, the raw material detailed information includes CO2 usage information relating to CO2 used in the manufacture of fuel or chemical products, as described in the raw material information management system 1 according to the first embodiment described above. Hereinafter, in the raw material information management system 1 according to this embodiment, the points that are common with the first embodiment will be omitted from the explanation, and the differences will be mainly described.

[0046] CO2 usage information includes at least one of the following: type of CO2 capture, CO2 source, amount of CO2 generated during CO2 transport, and means of CO2 transport. Examples of CO2 capture types include atmospheric CO2 captured by DAC and point source CO2 (such as CO2 emitted from steel mills, boilers, turbines, etc.). The CO2 source is the location information where the CO2 was collected, and in the case of point source CO2, it may also include the location information of the plant from which it was collected. Here, regarding the amount of CO2 generated during CO2 transport, the distance may be calculated from the location information of the CO2 source and the location information of the manufacturing plant, and the amount of CO2 emissions may be calculated based on the calculated distance and the information of the means of CO2 transport. This calculation process may be performed on the manufacturing plant side or in the raw material information management system 1.

[0047] The raw material information management system 1 acquires CO2 supply information from, for example, a CO2 recovery plant. The raw material information management system 1 manages and guarantees the origin of CO2 by comparing the CO2 usage information contained in the raw material details obtained from, for example, a manufacturing plant with the CO2 supply information. The raw material information management system 1 then transmits the raw material details data, including the CO2 usage information and the comparison results, to the user terminal 70. At this time, it may also create certificate data that guarantees the origin of CO2 and transmit the certificate data to the user terminal 70 in association with the raw material details data. Furthermore, the raw material information management system 1 may determine whether the raw material details, including the CO2 usage information, meet the requirements, generate certificate data indicating that the requirements are met, and transmit it to the user terminal 70 in association with the raw material details data.

[0048] According to this embodiment, by including CO2 usage information in the raw material detailed information, it is possible to manage and guarantee not only the electric power but also the origin of CO2.

[0049] 〔Third Embodiment〕Next, the raw material information management system 1 according to the third embodiment of the present disclosure will be described. The raw material information management system 1 according to this embodiment is the raw material information management system 1 according to the above-described first or second embodiment, and the raw material detailed information includes hydrogen usage information regarding hydrogen used in the production of fuels or chemical products. Hereinafter, in the raw material information management system 1 according to this embodiment, the description of the points common to the first or second embodiment will be omitted, and the different points will be mainly described.

[0050] The hydrogen usage information includes information on the power usage time, power usage amount, and power receiving system of the hydrogen production facility. For example, in the case of the production plant shown in FIG. 2, the raw material detailed information including information on the power usage time, power usage amount, and power receiving system in the water electrolysis device 14, the SOEC co-electrolysis device 15, and the hydrogen gas generation device 16 is transmitted from the user terminal 70 to the raw material information management system 1.

[0051] The raw material information management system 1 stores the raw material detailed information including the hydrogen usage information acquired from the user terminal 70 in the raw material detailed information database 45, and collates the hydrogen usage information with the power supply information acquired from each of the power generation plants A to C, thereby determining whether the hydrogen used as a raw material when manufacturing a fuel or a chemical product is blue hydrogen. Here, the collation process can be performed in the same manner as in the first embodiment described above.

[0052] Here, the raw material details may include location information for the manufacturing plant 10 and location information for the hydrogen production equipment. The raw material information management system 1 may determine whether the hydrogen used as a raw material when manufacturing fuel or chemical products is blue hydrogen based on the distance between the manufacturing plant 10 and the hydrogen production equipment. For example, even if hydrogen is produced using renewable energy, if the manufacturing plant 10 and the hydrogen production equipment are far apart, there is a possibility that a predetermined amount of CO2 will be generated when transporting hydrogen from the hydrogen production equipment to the manufacturing plant. Therefore, if the distance between the two exceeds a predetermined threshold, it may be determined that the requirements for blue hydrogen are not met, regardless of whether or not renewable energy is used to produce the hydrogen.

[0053] The raw material information management system 1 stores the raw material details data, including hydrogen usage information and the determination result of whether or not it is blue hydrogen, in the raw material details database 45 and transmits it to the user terminal 70. At this time, it may also create certificate data that guarantees that it is blue hydrogen, associate the certificate data with the raw material details data, and transmit it to the user terminal 70. Furthermore, the raw material information management system may determine whether or not the raw material details data, including hydrogen usage information, meets the requirements for life cycle assessment, generate certificate data that the requirements are met, associate it with the raw material details data, and transmit it to the user terminal 70.

[0054] According to this embodiment, by including hydrogen usage information in the raw material details, it becomes possible to manage and guarantee the power generated during hydrogen production.

[0055] [Fourth Embodiment] Next, a raw material information management system 1 according to the fourth embodiment of this disclosure will be described. The raw material information management system 1 according to this embodiment is a raw material information management system 1 according to any of the first to third embodiments described above, in which the raw material details include water usage information relating to the water used in the manufacture of fuel or chemical products. Hereinafter, in the raw material information management system 1 according to this embodiment, the explanation of points common to any of the first to third embodiments will be omitted, and the differences will be mainly explained.

[0056] Water usage information includes at least one of the following: the type of water used, water consumption, water source, and water volume. Examples of the type of water used include industrial wastewater, seawater, groundwater, and freshwater. When industrial wastewater or other types of wastewater are used, information indicating water quality may also be included. When seawater is used, the water usage information may include information on the desalination plant that produces freshwater from seawater. Information on the desalination plant may include the location of the desalination plant and information on the electricity used for desalination.

[0057] For example, in the case of the manufacturing plant shown in Figure 2, detailed raw material information, including water usage information regarding the water used in the hydrolysis unit 11, thermal power plant 12, CO reverse shift reactor 13, water electrolysis unit 14, and SOEC co-electrolysis unit 15, is transmitted from the user terminal 70 to the raw material information management system 1.

[0058] The raw material information management system 1 stores raw material details, including water usage information, obtained from the user terminal 70, in the raw material details database 45. If the water usage information includes desalination equipment information, the system may determine whether the electricity used to produce fresh water is renewable energy by comparing the electricity information used for desalination with the electricity supply information obtained from each power plant A to C. Here, the determination process can be carried out using the same method as in the first embodiment described above.

[0059] According to this embodiment, by including water usage information in the raw material details, it becomes possible to manage information about the water used in the manufacture of fuels or chemical products. This allows for detailed management of raw material information, which can then be used to optimize the manufacture of fuels or chemical products.

[0060] [Fifth Embodiment] Next, a raw material information management system 1a according to the fifth embodiment of the present disclosure will be described. The raw material information management system 1a according to this embodiment further includes a price calculation unit 48 in addition to the raw material information management system 1 according to any of the first to fourth embodiments described above. Hereinafter, in the raw material information management system 1a according to this embodiment, the explanation of points common to the first or second embodiment will be omitted, and the differences will be mainly explained.

[0061] Figure 6 is a diagram showing an example of the functions of the raw material information management system 1a according to this embodiment. As shown in Figure 6, the raw material information management system 1a further includes a price calculation unit 48. The price calculation unit 48 calculates the sales price of fuel or chemical products based on a plurality of raw material detail data stored in the raw material detail database 45. As described above, the raw material detail data is associated with the origin of each raw material, such as electricity, CO2, hydrogen, and water. Specifically, for electricity, it is associated with information such as whether it is renewable energy or not; for CO2, it is associated with whether it is atmospheric CO2 captured by DAC or point source CO2 or not; and for hydrogen, it is associated with whether it is blue hydrogen or not. For water, the type of water (industrial wastewater, seawater, groundwater, freshwater, etc.) is also included as information. The price calculation unit 48 sets the sales price of fuel or chemical products using the information on the origin of each raw material included in the raw material detail data.

[0062] The raw material information management system 1a may also acquire information such as the cost of raw materials used in manufacturing the fuel, for example, electricity costs and hydrogen purchase costs, from the user terminal 70 as detailed raw material information. The price calculation unit 48 may also acquire the market price of the fuel or chemical product.

[0063] The price calculation unit 48 has a price calculation formula that includes, for example, parameters related to the origin of raw materials and parameters related to raw material costs. Using this formula and the raw material origin information and raw material costs included in the raw material detailed data, it calculates the selling price. For example, the price calculation formula is weighted so that the cleaner the energy, the higher the price. The weighting may be adjusted by the fuel manufacturer. Once the price calculation unit 48 has calculated the selling price of the fuel or price product, it transmits the calculated price to the user terminal 70.

[0064] According to this embodiment, it is possible to calculate a sales price in accordance with the degree of environmental contribution and provide it to the fuel plant operator. This allows the fuel plant operator to use this sales price as a reference price and set an appropriate price in accordance with the degree of environmental contribution.

[0065] As mentioned above, the raw material detailed data includes detailed information about the raw materials used in the process of manufacturing fuels or chemical products. Therefore, this data can be used to calculate potential sites for future plant construction. For example, it is possible to use machine learning and statistical processing to calculate land where renewable energy electricity, CO2 supply, and water supply can all be provided cleanly from the raw material detailed data.

[0066] Although the present disclosure has been described above using embodiments, the technical scope of this disclosure is not limited to the scope described in the embodiments above. Various modifications or improvements can be made to the embodiments above without departing from the gist of the disclosure, and such modified or improved forms are also included in the technical scope of this disclosure.
