Description

[Technical field]

[0001] The present disclosure relates to a carbon sequestration assistance system, a carbon sequestration assistance device, and a vehicle. [Background technology]

[0002] As a measure against the depletion of fossil fuels and global warming caused by CO2 emissions, it has been proposed to turn biomass, such as woody biomass, which has traditionally been treated as waste, into a resource and make effective use of it. For example, sawmills and timber markets generate large amounts of bark. In forests, parks, and rivers, mowing and pruning generate large amounts of branches and leaves. By collecting these instead of disposing of them and turning them into resources by producing biofuels such as biochar, it is possible to reduce waste disposal costs and CO2 emissions.

[0003] However, such biomass materials, such as wood and branches and leaves, are widely scattered throughout the country. Therefore, it is desirable to efficiently recover and recycle such biomass materials. For example, Patent Document 1 discloses a waste material recycling system in which waste materials are steadily supplied from waste material dealers scattered throughout the country to processors, who then process the waste materials into carbonized materials (e.g., wood carbonized powder), thereby achieving effective use of the waste materials. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2004-78387 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the waste material recycling system disclosed in Patent Document 1 provides a stable supply of waste materials between waste material dealers and processors, and does not take into consideration the efficient recovery and recycling of widely scattered biomass raw materials. For effective utilization of biomass materials, it is important to efficiently recover the biomass materials.

[0006] The present disclosure has been made in consideration of the above circumstances, and aims to provide a carbon fixation support system, a carbon fixation support device, and a vehicle that can support the efficient recovery of biomass raw materials. [Means for solving the problem]

[0009] One aspect of the present disclosure is a carbon fixation assistance system including the carbon fixation assistance device and the vehicle.

[Figure 4] FIG. 2 is a functional configuration diagram showing an example of functions provided in a carbon fixation support device according to an embodiment of the present disclosure. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of a carbon fixation support system, a carbon fixation support device, and a vehicle according to the present disclosure will be described with reference to the drawings. Fig. 1 is a system configuration diagram that shows a schematic configuration of a carbon fixation support system 1 according to this embodiment. As shown in Fig. 1, a plurality of vehicles 10 (specifically, a carbonization management device 20 (see Fig. 3) mounted on the vehicles 10) and a carbon fixation support device 50 are connected to a network 8. In the example shown in Fig. 1, three vehicles 10 are shown, but the number of connected vehicles 10 is not limited to this. Each vehicle 10 and the carbon fixation support device 50 are configured to be able to communicate with each other via the network 8, for example.

[0014] Fig. 2 is a diagram showing a schematic configuration of a vehicle 10 according to this embodiment. The vehicle 10 travels around, for example, the generating site of biomass raw materials and collects the biomass raw materials. Furthermore, the vehicle 10 is equipped with a bioproduct production system 2 that produces bioproducts from the collected biomass raw materials. Examples of bioproducts include biochar and biofuel. The vehicle 10 may also be equipped with a conveyor 3 as a raw material transport means for supplying the biomass raw material to the bioproduct manufacturing system 2.

[0015] The vehicle 10 may also be equipped with a crane 4. The crane 4 is used, for example, to carry biomass raw materials into the bioproduct manufacturing system 2. The crane 4 is also used to carry out bioproducts manufactured by the bioproduct manufacturing system 2. For example, a cage is connected to the tip of the crane 4 via a wire, and the biomass raw materials and bioproducts are stored in the cage, thereby carrying in the biomass raw materials and carrying out the bioproducts.

[0016] The vehicle 10 is also provided with a drone port (not shown) that functions as a takeoff and landing base for the drone (aircraft) 5. The drone port is provided with a drone charging device (not shown) for charging the drone 5. The drone 5 functions, for example, as a device that supports the work of collecting biomass raw materials. For example, the drone 5 is used to search for a collection site for the biomass raw materials and obtain information regarding the collection site. The drone 5 may also function, for example, as a device that supports the work of spreading or incorporating a bioproduct (e.g., biochar) produced by the biological product production system 2 into farmland or the like. For example, the drone 5 may be used to search for land in which to incorporate biochar and obtain information regarding the land in which to incorporate biochar.

[0017] The drone 5 may also be equipped with a collection device that collects and transports biomass raw materials and bioproducts. By equipping the drone 5 with the collection device, it becomes possible not only to collect information on collection locations but also to collect biomass raw materials and transport them to the vehicle 10, and to transport bioproducts from the vehicle 10 to agricultural land or the like for scattering. The recovery device may use known technology. For example, a claw-shaped support tool that grabs the transported object is provided at the tip of a support wire that is unwound from a winch fixed to the drone 5, and the support tool opens and closes to enable recovery, scattering, etc. of the transported object.

[0018] The bioproduction system 2 includes, for example, a drying device 11, a grinder 12, a pyrolysis furnace 13, and a combustion chamber 14. The drying device 11 dries, for example, the biomass raw material fed from the conveyor 3. The biomass raw material is, for example, woody biomass (biological resource) made of wood, forest residues such as branches and leaves generated during tree felling and lumber processing, bark generated from sawmills, wood pellets and wood chips generated from bark and sawdust, etc. For example, a belt dryer that dries the biomass raw material placed on a belt by contacting it with high-temperature gas can be used as the drying device 11. Also, instead of a belt dryer, a rotary kiln dryer, a disk dryer, or the like can be used as the drying device 11. The heating method of the drying device 11 may be either indirect heating or direct heating.

[0019] The pulverizer 12 pulverizes the dried biomass raw material into particles of an appropriate size. The pulverizer 12 is also configured to be capable of pulverizing the bioproducts (e.g., biochar, biofuel, etc.) produced in the pyrolysis furnace 13. The pyrolysis furnace 13 generates bio-products such as biochar and biofuel by pyrolyzing the biomass raw material. The pyrolysis furnace 13 includes a combustion chamber 14. The combustion chamber 14 burns fuel to generate heat. A part of the biomass raw material pulverized by the pulverizer 12 may be fed into the combustion chamber 14 as fuel. The pyrolysis furnace 13 indirectly heats the biomass raw material with heat supplied from the combustion chamber 14, causing pyrolysis and gasification reactions. As the pyrolysis progresses, the biomass raw material is carbonized while generating pyrolysis gas. The generated biofuel (e.g., biochar, etc.) is discharged and stored in, for example, a predetermined collection container (not shown). As described above, the biofuel such as biochar may be pulverized by the pulverizer 12 and then stored in the collection container. The heating method of the pyrolysis furnace 13 may be either indirect heating or direct heating. Examples of the pyrolysis furnace 13 include an indirect heating rotary kiln, a direct heating rotary kiln, a fluidized bed furnace, and a screw-type carbonization furnace.

[0020] Here, the configuration of the biological product manufacturing system 2 is an example, and is not limited to this. For example, the configuration may be such that the pulverizer 12 is omitted. Furthermore, the operation control of the biological product manufacturing system 2 may be appropriately combined with known techniques. For example, known techniques can be appropriately adopted for the various operating conditions of the above-mentioned biological product manufacturing system 2 (e.g., drying temperature, drying time, fineness of pulverization, pyrolysis temperature, time, oxygen concentration, etc.).

[0021] As shown in Fig. 3, the vehicle 10 is equipped with a weight measuring device (weight measuring means) 31 that measures the weight of the biomass raw material, and a composition analyzing device (composition analyzing means) 32 that performs a composition analysis of the biomass raw material. The composition analyzing device 32, for example, performs a composition analysis of the biomass raw material to measure the amount of carbon contained in the biomass raw material, specifically, the carbon content per unit weight of the biomass raw material. As an analytical method, for example, the fixed carbon ratio based on "JIS M 8812:2004 (or 2006) Coals and cokes - Methods of proximate analysis" or the "Liebig modified method" described in "JIS M 8813:2004 (or 2006) Coals and cokes - Methods of elemental analysis" can be used.

[0022] Furthermore, the vehicle 10 may be equipped with a product weight measuring device 34 that measures the weight of the bioproduct, and a product composition analyzing device 35 that performs composition analysis of the bioproduct. The product composition analyzing device 35 performs composition analysis of the bioproduct to measure the amount of carbon contained in the bioproduct, specifically, the carbon content per unit weight of the bioproduct. For example, "JIS M 8812:2004 (or 2006) Coals and cokes - Industrial analysis method" or the like can be used as an analysis method. In addition, the degree of refinement may be measured. For example, when the bioproduct is biochar, the degree of refinement is a value determined by the degree of electrical resistance measured as a result of passing an electric current through the biochar, and is measured using a machine called a refining meter. Here, the value indicated by the degree of refinement is low when the degree of carbonization is high, i.e., when the carbon purity is high and the quality of the biochar is good, the electrical resistance will be low and the degree of refinement will be low. Conversely, when the degree of carbonization is low, i.e., when the carbon purity is low and the quality of the biochar is poor, the electrical resistance will be high and the degree of refinement will be high.

[0023] As shown in FIG. 3, the vehicle 10 is equipped with a carbonization management device 20 for managing a series of processes from collection of biomass raw materials to production of bioproducts such as biochar. The carbonization management device 20 is a computer, and includes, for example, a CPU (Central Processing Unit: processor), a main memory, a secondary storage, an external interface, a communication interface, and the like. A series of processes for realizing various functions described below is stored in a secondary storage device or the like in the form of a program, for example, and the CPU (processor) reads out the program into the main storage device and executes information processing and arithmetic processing to realize various functions. The program may be installed in the secondary storage device in advance, provided in a state stored in a non-transient computer-readable storage medium, or distributed via a wired or wireless communication means. Examples of non-transient computer-readable storage media include magnetic disks, optical magnetic disks, CD-ROMs, DVD-ROMs, and semiconductor memories.

[0024] As shown in FIG. 3, the carbonization management device 20 includes a communication unit 21 and a position information acquisition unit 22. The communication unit (transmission means / reception means) 21 is connected to an external device via a network 8 or the like, and transmits and receives information to and from the external device. Examples of the external device include a carbon fixation assistance device 50, a drone 5, another vehicle 10, and the like. The position information acquisition unit 22 acquires the position of the vehicle 10. The position information acquisition unit 22 is, for example, a GPS, and various known devices and techniques may be appropriately adopted.

[0025] The carbonization management device 20 also includes a raw material information acquisition unit 23 , a raw material carbon amount calculation unit 24 , and an area information generation unit 25 . The raw material information acquisition unit 23 acquires the weight of the biomass raw material measured by the weight measurement device 31 and the analysis results by the composition analysis device 32, specifically, the carbon content per unit weight of the biomass raw material. The raw material carbon amount calculation unit 24 calculates the raw material carbon amount, which is the amount of carbon contained in the biomass raw material, using the composition analysis results and weight of the biomass raw material. Specifically, the amount of carbon contained in the biomass raw material is calculated by multiplying the weight by the carbon content per unit weight of the biomass raw material. The area information generating unit 25 generates carbon fixation area information that associates the location information of where the biomass raw material was collected with the raw material carbon amount. The carbon fixation area information generated by the area information generating unit 25 is transmitted to the carbon fixation support device 50 via the communication unit 21.

[0026] The carbonization management device 20 also includes an exhaust carbon amount calculation unit 26 and a carbonization information generation unit 27. The carbon emission calculation unit 26 communicates with, for example, a vehicle control device 36 mounted on the vehicle 10, and calculates the amount of carbon emission emitted to recover the biomass raw material. For example, the amount of carbon emission can be calculated from the amount of fuel consumed (for example, the amount of electricity consumed, the amount of diesel consumed, the amount of gasoline consumed). The carbon emission calculation unit 26 has, for example, a conversion formula for converting the amount of fuel consumed into the amount of carbon emission, and calculates the amount of carbon emission by substituting the amount of fuel consumed into the conversion formula. In addition, for example, the amount of fuel consumed can also be found from the amount of fuel refueled when refueling the vehicle, and the amount of carbon emission may be calculated by inputting the amount of fuel refueled to the carbon emission calculation unit 26.

[0027] The carbonization information generation unit 27 generates carbon fixation information using the raw material carbon amount calculated by the raw material carbon amount calculation unit 24 and the emitted carbon amount calculated by the emitted carbon amount calculation unit 26. For example, the carbonization information generation unit 27 calculates a net carbon amount by subtracting the emitted carbon amount from the raw material carbon amount, and outputs the net carbon amount to the communication unit 21 as carbon fixation information. The communication unit 21 transmits the carbon fixation information to the carbon fixation support device 50 .

[0028] The carbonization management device 20 may also include a product information acquisition unit 28 , a product carbon amount calculation unit 29 , and a standard compliance determination unit 30 . The product information acquisition unit 28 acquires the weight of the bioproduct measured by the product weight measurement device 34 and the analysis results by the product composition analysis device 35, specifically, the carbon content per unit weight of the bioproduct. The product carbon amount calculation unit 29 calculates the product carbon amount, which is the amount of carbon contained in the biological product, by using the composition analysis result and the weight of the biological product. Specifically, the amount of carbon contained in the biological product is calculated by multiplying the weight by the carbon content per unit weight of the biological product. The standard compliance determination unit 30 determines whether or not the carbon amount contained in the bioproduct calculated by the product carbon amount calculation unit 29 complies with the standard information. For example, the standard compliance determination unit 30 determines whether or not a manufactured bioproduct (e.g., biochar, biofuel, etc.) has a quality that allows sale, etc., by determining whether or not the manufactured bioproduct satisfies a specific standard that has been established for it.

[0029] Next, a description will be given of the carbon fixation support device 50. The carbon fixation support device 50 is configured to be able to communicate with the vehicle 10, and supports carbon fixation by sending and receiving information to and from the vehicle 10 and the like. The carbon fixation support device 50 is a computer, and includes, for example, a CPU (Central Processing Unit: processor), a main memory, a secondary storage, an external interface, a communication interface, and the like. A series of processes for realizing various functions described below is stored in a secondary storage device or the like in the form of a program, and the CPU (processor) reads out this program into the main storage device and executes information processing and arithmetic processing to realize various functions. The program may be installed in the secondary storage device in advance, provided in a state stored in a non-transient computer-readable storage medium, or distributed via a wired or wireless communication means. Examples of non-transient computer-readable storage media include magnetic disks, magneto-optical disks, CD-ROMs, DVD-ROMs, and semiconductor memories.

[0030] Fig. 4 is a functional configuration diagram showing an example of functions included in the carbon fixation support device 50. As shown in Fig. 4, the carbon fixation support device 50 includes, for example, a communication unit 51, an area information acquisition unit 52, an area information database 53, a map creation unit 54, and an area information provision unit 55.

[0031] The communication unit 51 is connected to an external device via a network 8 or the like, and transmits and receives information to and from the external device. Examples of the external device include a plurality of vehicles 10, a drone 5, and the like. The area information acquisition unit 52 acquires carbon fixation area information from each vehicle 10 , and stores the acquired carbon fixation area information in the area information database 53 .

[0032] The area information database 53 stores carbon fixation area information received from each vehicle 10. Here, as described above, the carbon fixation area information is, for example, information that associates location information where biomass raw materials were collected with the amount of carbon contained in the collected biomass raw materials. As a result, the area information database 53 stores information on locations where biomass raw materials were collected in the past and information on the amount of carbon contained in the biomass raw materials collected at those locations.

[0033] The map creation unit 54 creates a collection area map showing the collection locations of the biomass raw materials based on the carbon fixation area information accumulated in the area information database 53. For example, the map creation unit 54 creates the collection area map by plotting the collection locations of the biomass raw materials on a map. The collection area map also shows, for example, the amount of carbon contained in the biomass raw materials collected at each collection location in association with each collection location. For example, the amount of carbon may be shown as a numerical value. The collection area map may also be a map showing the ratio of the carbon amount of the biomass raw materials to the area as a heat map.

[0034] When the area information providing unit 55 receives an area information transmission request including the vehicle's location information from the vehicle 10, the area information providing unit 55 specifies a target area corresponding to the location information of the vehicle 10. For example, the area information providing unit 55 specifies a predetermined range (e.g., a range with a radius of 2 km) centered on the location information of the vehicle 10 as the target area. Here, the area information transmission request may include vehicle identification information capable of identifying the vehicle 10, instead of the location information of the vehicle 10. In this case, the request has information that associates the vehicle identification information with the target area that the vehicle 10 is responsible for, and the target area corresponding to the vehicle identification information can be identified based on this information.

[0035] Next, the area information providing unit 55 acquires a collection area map corresponding to the specified target area, and transmits the acquired collection area map to the vehicle 10. As a result, the collection area map is transmitted via the communication unit 51 to the vehicle 10 that is the source of the area information transmission request. This enables the driver of the vehicle 10 to efficiently collect biomass materials based on the received collection area map.

[0036] The carbon fixation assistance device 50 also includes a carbon information acquisition unit 56 , a carbon information database 57 , and a carbon credit application unit 58 . The carbon information acquisition unit 56 acquires carbon fixation information from the vehicle 10, and stores the acquired carbon fixation information in the carbon information database 57. As a result, the carbon information database 57 accumulates the carbon fixation information received from each vehicle 10. The carbon credit application unit 58 applies for carbon credits to a carbon credit certification organization based on the carbon fixation information stored in the carbon information database 57 .

[0037] Next, the carbon fixation support method according to this embodiment will be described. For example, when starting collection of biomass raw materials, the vehicle 10 transmits an area information transmission request to the carbon fixation assistance device 50 together with the current location information acquired by the location information acquisition unit 22. When the carbon fixation support device 50 receives a request to send area information, it identifies the target area based on the location information included in the request to send area information, obtains a collection area map corresponding to the identified target area, and transmits the obtained collection area map to the vehicle 10 that sent the request to send area information.

[0038] When the vehicle 10 receives the collection area map, the vehicle 10 displays the collection area map on an in-vehicle display or the like. The driver of the vehicle 10 checks the collection area map and drives the vehicle 10 according to the collection area map to collect the biomass raw materials. At this time, the collection area map shows the carbon amount of the biomass raw materials expected to be collected at each collection location, so the driver can collect the biomass raw materials efficiently by preferentially going around locations with a large carbon amount. Regarding the collection of the biomass raw materials, in addition to moving the vehicle to the collection location, the drone 5 may be flown to collect and transport the biomass raw materials using the drone 5. The drone 5 can also be used to search for a collection location for the biomass raw materials in the vicinity. In this way, the drone 5 is used to search for a new collection location for the biomass raw materials, and the biomass raw materials are collected at the new collection location, making it possible to enrich the collection area map managed by the carbon fixation support device 50.

[0039] When biomass raw materials are collected at a collection site, the composition of the collected biomass raw materials is analyzed by a composition analyzer 32, and the weight is measured by a weight measuring device 31. Then, based on the results of these analyses and the measured weight, the amount of carbon contained in the biomass raw materials is calculated. Next, carbon fixation area information in which the calculated carbon amount and the recovery location are associated with each other is generated and transmitted to the carbon fixation assistance device 50 .

[0040] When the carbon fixation assistance device 50 receives the carbon fixation area information, it stores this information in the area information database 53 . Then, multiple vehicles 10 generate carbon fixation area information at each biomass raw material collection site and transmit it to the carbon fixation support device 50, so that new information is continually accumulated in the area information database 53, and the collection area map is continually updated accordingly.

[0041] Furthermore, the vehicle 10 calculates the amount of carbon emitted from the vehicle 10 in order to move to the collection site. Then, the amount of carbon emitted is subtracted from the carbon amount of the biomass raw material to calculate the net carbon amount, which is transmitted to the carbon fixation support device 50 as carbon fixation information. When the carbon fixation support device 50 receives the carbon fixation information, it stores it in the carbon information database 57. Then, at a predetermined timing, an application for carbon credits is made for the certification period based on the carbon fixation information stored in the carbon information database 57. The application may be made every time carbon fixation information is received, or may be made collectively at predetermined time intervals (for example, every day, every month, every few months, etc.).

[0042] In addition, in the vehicle 10, the bioproduct manufacturing system 2 is operated to manufacture a bioproduct from the collected biomass raw material, and the composition of the bioproduct is analyzed by the product composition analyzer 35, while the weight is measured by the product weight measuring device 34. The amount of carbon contained in the bioproduct is calculated based on the analysis results and the measured weight. Next, it is determined whether the components contained therein, such as the amount of carbon, meet product standards for judging the quality of the bioproduct. In this way, by determining whether the bioproduct meets a certain level of quality based on the amounts of components contained in the bioproduct, the quality of the bioproduct can be maintained at a certain level or higher, and a bioproduct of stable quality can be provided to the user.

[0043] As described above, according to this embodiment, the vehicle 10 that collects biomass raw materials and the carbon fixation support device 50 that supports carbon fixation are configured to be able to communicate with each other via the network 8. Then, the vehicle 10 transmits to the carbon fixation support device 50 carbon fixation area information that associates location information where the biomass raw materials were collected with the raw material carbon amount, which is the amount of carbon contained in the collected biomass raw materials. The carbon fixation support device 50 accumulates the carbon fixation area information received from each vehicle in the area information database 53. This makes it possible to accumulate and manage a large amount of data about biomass raw material collection sites.

[0044] Furthermore, according to this embodiment, when the carbon fixation support device 50 receives an area information transmission request including location information or vehicle identification information capable of identifying the vehicle 10 from the vehicle 10, the carbon fixation support device 50 identifies a target area from these pieces of information and transmits a collection area map corresponding to the identified target area to the vehicle 10. This makes it possible to notify the vehicle 10 of collection locations for biomass raw materials that exist around the current location of the vehicle 10. As a result, it is possible to support efficient collection of biomass raw materials. Furthermore, since the carbon fixation area information is associated with not only location information of the collection location but also information on the amount of carbon contained in the biomass raw materials collected at that collection location, it is possible to identify a collection location where a large amount of carbon can be collected, and it becomes possible to further improve collection efficiency.

[0045] The carbon fixation support system 1, the carbon fixation support device 50, and the vehicle 10 according to the present disclosure have been described above using embodiments, but the technical scope of the present disclosure is not limited to the scope described in the above embodiments. Various modifications or improvements can be made to the above embodiments without departing from the gist of the disclosure, and forms with such modifications or improvements are also included in the technical scope of the present disclosure. In addition, the above embodiments may be combined as appropriate.

[0046] For example, the configuration of the biological product manufacturing system 2 in the above-described embodiment is merely an example, and is not limited thereto. For example, the crusher 12 may be omitted. Also, a cutter may be used instead of the crusher 12.

[0047] For example, in the above-described embodiment, the carbon fixation area information is information that associates the location information of where the biomass raw material was collected with the amount of raw material carbon, but is not limited to this. For example, the carbon fixation area information may be information that is associated with the amount of product carbon in addition to or instead of the amount of raw material carbon. Furthermore, the carbon fixation area information may include at least one of the carbon amount per unit weight of the biomass raw material collected at the collection location, the accumulated amount of the biomass raw material collected at the collection location, the carbon amount per unit weight of the bioproduct produced from the biomass raw material collected at the collection location, or the accumulated amount of the bioproduct produced from the biomass raw material collected at the collection location. In addition, the collection area map created based on the carbon fixation area information may, for example, display this information numerically, or may be displayed as a heat map in which the information is displayed in colors or shades corresponding to the numerical values.

[0048] The carbon fixation support system 1 may also manage land on which bioproducts (e.g., biochar) are spread or incorporated in the same manner as for the collection site of biomass raw materials. For example, when the vehicle 10 (or the drone 5) spreads or incorporates biochar into farmland or the like, information associating the location of the spreading or incorporating with the weight of the spread or incorporated bioproduct may be transmitted to the carbon fixation support device 50, and the carbon fixation support device 50 may manage this information in an integrated manner.

[0049] The carbon fixation support device 50 may have a land database that acquires appropriate land use and soil classification information from public information such as the land classification survey and land use map by the Ministry of Land, Infrastructure, Transport and Tourism, the eMAFF Farmland Navi by the Ministry of Agriculture, Forestry and Fisheries, and the Japan Soil Inventory by the National Agriculture and Food Research Organization, and accumulates land information on which carbon fixation (spreading or mixing of bioproducts) is performed based on the information. When an area information transmission request for spreading or mixing of bioproducts is received from the vehicle 10, land information close to the current position may be transmitted from the land database to the vehicle 10. This allows the bioproduct to be used efficiently. If the vehicle 10 transmits the analysis results of the composition components of the bioproduct to the carbon fixation support device 50, it is also possible to provide land information suitable for the components of the bioproduct.

[0050] In addition, the carbon fixation support system 1 may further have a function of predicting the remaining lifespan of the biological product manufacturing system 2 based on operation information of the vehicle 10, operation information of the biological product manufacturing system 2, the results of an analysis of the compositional components of the biological product, the accumulation and deposition status of by-products, the frequency of part replacement, the degree of thinning due to corrosion and wear, etc., and proposing the content and timing of maintenance based on the predicted remaining lifespan.

[0051] The carbon fixation assistance system, the carbon fixation assistance device, and the vehicle described in the above-described embodiment can be understood, for example, as follows.

[0052] A carbon fixation support device (50) according to a first aspect of the present disclosure is a carbon fixation support device (50) configured to be able to communicate with a vehicle (10) that recovers biomass raw materials, and includes an area information acquisition means (52) that acquires from the vehicle carbon fixation area information that associates location information of the recovered biomass raw material with information on a raw material carbon amount, which is the amount of carbon contained in the recovered biomass raw material, or information on a product carbon amount, which is the amount of carbon contained in a bioproduct produced from the recovered biomass raw material, an area information database (53) that accumulates the acquired carbon fixation area information, and an area information provision means (55) that, when an area information transmission request including location information or vehicle identification information capable of identifying the vehicle is received from the vehicle, identifies a target area identified from the location information or vehicle identification information of the vehicle, acquires carbon fixation area information corresponding to the identified target area from the area information database, and transmits the carbon fixation area information to the vehicle.

[0053] According to the above aspect, the carbon fixation area information is acquired from the vehicle, and the area information database is provided, which associates location information of where the biomass raw material was collected with information on the raw material carbon amount, which is the amount of carbon contained in the biomass raw material collected at the collection location, or the product carbon amount, which is the amount of carbon contained in a bioproduct produced from the collected biomass raw material, and stores the acquired carbon fixation area information. This makes it possible to comprehensively manage the carbon fixation area information received from the vehicle. This makes it possible to store a lot of data on the collection locations of biomass raw materials. Furthermore, when an area information transmission request including location information or vehicle identification information capable of identifying the vehicle is received from a vehicle, a target area identified from the vehicle's location information or vehicle identification information is identified, and carbon fixation area information corresponding to the identified target area is obtained from the area information database and transmitted to the vehicle. This makes it possible to notify the vehicle of a collection location for biomass raw materials that exists around the current location of the vehicle. This makes it possible to support efficient collection of biomass raw materials. Furthermore, the carbon fixation area information is associated with not only the location information of the collection location, but also information on the amount of carbon contained in the biomass raw materials collected at the collection location or the amount of carbon contained in the bioproducts produced from those biomass raw materials, so that a collection location where a large amount of carbon can be collected can be identified, making it possible to further improve collection efficiency.

[0054] In the first aspect, the carbon fixation support device (50) according to the second aspect of the present disclosure includes a map creation means (54) that creates a collection area map indicating a collection location of biomass raw materials based on the carbon fixation area information accumulated in the area information database (53), and when the area information providing means (55) receives the area information transmission request, it transmits to the vehicle (10) a collection area map corresponding to a target area identified from the position information of the vehicle (10) or the vehicle identification information.

[0055] According to the above aspect, a collection area map is created in which collection locations and carbon amount information are associated based on the carbon fixation area information, and this collection area map is transmitted to the vehicle. In this way, since information showing the collection locations of the biomass raw materials on the map is transmitted, it becomes possible to easily move the vehicle to the desired collection location.

[0061] According to the above aspect, carbon fixation area information that associates the amount of raw material carbon, which is the amount of carbon contained in the recovered biomass raw materials, with location information on where the biomass raw materials were recovered is transmitted to the carbon fixation support device. This enables the carbon fixation support device to manage how much carbon was recovered at which recovery location.
