Description

[Technical field]

[0001] The present invention relates to a method for reducing CO2 emissions from businesses that consume biofuels over a given period of time. 2 This relates to an emission reduction calculation system. [Background technology]

[0002] In recent years, from the perspective of BCP (a plan for businesses to minimize damage and continue or recover from business emergencies such as disasters), an increasing number of businesses are installing private generators to ensure power in emergencies. However, fuel supplied (refueled) to the fuel tank of a private generator begins to deteriorate (deteriorate in quality) over time after a certain period of time (usable period) has passed since it was supplied, and the use of such deteriorated fuel can cause breakdowns in the fuel system. For this reason, it is preferable to replace (change) the fuel in the fuel tank with undeteriorated (i.e., new) fuel as needed.

[0003] In recent years, from the perspective of preventing global warming, 2 Reducing carbon dioxide (CO) emissions has become an urgent issue. 2 Businesses are expected to take steps to reduce CO emissions. For example, businesses that generate waste cooking oil, such as restaurants and food factories, can reduce CO emissions by recycling the oil instead of incinerating it and using it as raw material for biofuel, or by using the biofuel as fuel for generators. 2 This can contribute to reducing CO emissions. 2 Reduce emissions and CO 2 There are systems that calculate reduction credits (see Patent Document 1 below). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6763594 Summary of the Invention [Problem to be solved by the invention]

[0005] Regarding the fuel replacement (exchange) of the fuel tank mentioned above, if there is a lot of fuel remaining in the fuel tank at the time of replacement, the amount of wasted fuel will be large, which is not economical, so the timing is important. 2 Regarding emissions reduction efforts, if the results can be quantitatively visualized, businesses will be able to publicize the concrete results of their efforts to the outside world.

[0006] In view of the above, the present invention provides a method for notifying a company of the appropriate timing for replacing aged fuel in a fuel tank and for calculating the CO2 emission reduction amount for a predetermined period of time. 2 The objective is to provide a system capable of calculating emission reductions. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides 2 The emission reduction calculation system calculates the CO2 emissions for a specified period for businesses that consume biofuel or a mixture of biofuel in the fuel tank of their private generators. 2 A system for calculating an emission reduction amount, comprising: a supplier terminal of a fuel supplier that supplies fuel to a fuel tank of a private power generator that uses biofuel or a mixed fuel as fuel; The fuel tank includes a sensor that is attached to the fuel tank and detects that the amount of fuel in the fuel tank has reached a lower limit amount set in the fuel tank, and a server that can communicate with the supplier terminal and the sensor, and the server receives from the supplier terminal information on the fuel supply date when the fuel supplier supplies fuel to the fuel tank from an empty state, and information on the amount of fuel in the fuel tank at the time of completion of fuel supply, and transmits information to the supplier terminal notifying the timing of replacing the fuel in the fuel tank when a previously set and stored usable period of the fuel has elapsed counting from the fuel supply date, or when a detection signal is received from the sensor before the usable period has elapsed, calculates the amount of fuel consumed by the business operator based on at least two pieces of information, the information on the amount of fuel in the fuel tank at the time of completion of fuel supply, and the information on the amount of waste fuel removed from the fuel tank by replacing the fuel in the fuel tank, and calculates a first CO2 emission caused by the business operator's consumption of fuel based on the amount of consumption. 2 Calculate the amount of emission reduction and, assuming that the waste fuel is processed into recycled fuel, calculate the second CO reduction by using the waste fuel as a raw material for recycled fuel based on the fuel quantity information of the waste fuel. 2 Calculate the amount of emission reduction and the first CO 2 Emissions reductions and second CO 2 Based on the amount of CO emissions reductions, 2 Calculate emission reductions.

[0008] In addition, the above-mentioned CO 2In the emission reduction calculation system, the server may transmit information to the supplier terminal notifying the timing of replacing the fuel in the fuel tank when a preset and stored usable period of the fuel has elapsed from the fuel supply date or when a detection signal is received from the sensor, whichever is earlier. The server may also predict the amount of fuel consumed by the business operator from the fuel supply date until the preset and stored usable period of the fuel has elapsed based on the actual data of the business operator's consumption, and determine whether or not it is necessary to refuel the fuel tank before the usable period of the fuel has elapsed based on the predicted consumption and information on the amount of fuel in the fuel tank that exceeds the lower limit amount at the time of completion of the fuel supply, and if it determines that refueling is necessary, transmit information on the amount of fuel that needs to be refueled by the time the usable period of the fuel has elapsed to the supplier terminal. In addition, when the server receives information notifying the user of an emergency in which the use of a private generator is essential, the server may predict the operator's fuel consumption for the period from the date of fuel supply to the time of receipt based on the operator's actual consumption data, calculate the amount of fuel that can be delivered to the fuel tank based on the predicted consumption information, and transmit information on the calculated amount of fuel that can be delivered to the supplier terminal. Effect of the Invention

[0009] According to the present invention, the fuel supplier can know the appropriate timing to replace the aged fuel in the fuel tank. 2 Calculate the amount of CO emissions reduction. 2 The CO reduction figures for businesses 2 The results of emission reduction efforts can be quantitatively visualized, and businesses can then 2 CO using emission reduction figures 2 The results of our emissions reduction efforts can be publicly promoted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited thereto. 2 Emissions Reduction Calculation System (hereinafter simply referred to as "CO 2 The emission reduction calculation system (sometimes called the "emission reduction calculation system") calculates the CO2 emissions reduction amount for a specified period of time for businesses that consume biofuels or biofuel blends in their fuel tanks for private generators. 2 This is a system that calculates the amount of CO 2 The emission reduction calculation system is applicable in certain cases. 2 Before we go into the details of the emission reduction calculation system, let us first 2 We will explain the cases (situations) in which the emission reduction calculation system can be applied. 2FIG. 2 is a diagram for explaining a case in which the emission reduction calculation system can be applied.

[0012] CO 2 CO emission reduction calculation system 2 The businesses for which the emission reductions are calculated are businesses that discharge waste cooking oil, such as restaurants and food factories. Waste cooking oil is used cooking oil. For example, restaurants and food factories generate waste cooking oil because they use cooking oil and fats in the process of manufacturing, processing, cooking, and other aspects of food. In addition, the above businesses have private generators for business use. By installing such private generators, the above businesses can secure electricity in emergencies and continue their business even during, for example, a power outage (when the power company stops distributing electricity).

[0013] As shown in Figure 1(a), waste cooking oil discharged by businesses is collected and sent to a biofuel production plant. At the biofuel production plant, the collected waste cooking oil is processed into biofuel to produce fuel containing biofuel (biofuel or mixed fuel containing biofuel). Biofuel, also known as biomass fuel, is fuel made from biological resources (biomass) such as plants and animals, and examples include biodiesel and bioethanol.

[0014] The fuel produced at biofuel production plants is biofuel-mixed diesel (B5 fuel), which is produced by mixing biodiesel fuel with diesel at a ratio of 5 percent. The biodiesel fuel contained in B5 fuel is a diesel engine fuel produced from vegetable oils such as rapeseed oil, soybean oil, and corn oil, and is made from plants that have grown by absorbing carbon dioxide on Earth. For this reason, the carbon dioxide emissions emitted when biodiesel fuel is burned are theoretically counted as zero. B5 fuel has the advantage that it can be mixed with diesel and used, making it possible to handle it in the same way as diesel.

[0015] The fuel produced in the biofuel production plant is filled (supplied) by a fuel supplier into the fuel tank of the business's private generator, and is consumed by the business. A fuel supplier is a party that supplies fuel to the fuel tank of the business's private generator, such as a fuel delivery company. As described above, the fuel filled into the fuel tank starts to deteriorate over time after a certain period of time has passed since filling. For this reason, the deteriorated fuel is removed from the fuel tank and replaced with new (undeteriorated) fuel. Therefore, fuel is filled into an empty fuel tank not only when a new fuel tank is installed, but also when the fuel tank is replaced or refueled.

[0016] The fuel in the fuel tank is consumed and reduced as the business uses the private generator (see Figure 1 (b)). If the private generator is for regular use or for both regular and emergency use, the fuel in the fuel tank is consumed mainly for regular operations. If the private generator is for emergency use, the fuel in the fuel tank is consumed mainly for generator inspections and emergency training. The fuel in the fuel tank may be replenished (topped up) by the fuel supplier as appropriate.

[0017] When a certain period of time has passed since refueling, the fuel is replaced and the fuel is removed from the fuel tank. The fuel removed from the fuel tank at this time is called waste fuel. Waste fuel can be incinerated, but instead is sent to a recycled fuel manufacturing plant as shown in Figure 1(c) and processed into recycled fuel (e.g. recycled heavy oil). The recycled fuel is transported from the recycled fuel manufacturing plant and used, for example, as fuel for boilers, greenhouse heating, agricultural machinery, etc.

[0018] In the above case, the business operator not only contributes to environmental conservation by providing the waste cooking oil to the biofuel production plant as a raw material for biofuel instead of incinerating it, but also reduces CO2 emissions by consuming the biofuel and providing the waste fuel to the renewable fuel production plant as a raw material for renewable fuel. 2 In this case, CO 2The emission reduction calculation system calculates the CO emissions of businesses from the time they finish refueling their fuel tanks until they switch fuel. 2 Calculate the emission reductions, i.e. CO 2 The emission reduction calculation system calculates the amount of CO2 reduced by businesses through their consumption of biofuels during the above period. 2 Emissions (First CO 2 The amount of CO emissions reduced by recycling waste fuel removed from fuel tanks during fuel changes instead of incinerating it was also calculated. 2 Emissions (secondary CO 2 Then, calculate the CO 2 The emission reduction calculation system calculates the first CO 2 Emissions reductions and second CO 2 Based on the amount of emission reduction (e.g., the first CO 2 Emissions reductions and second CO 2 (Combined with the emission reduction amount) 2 Calculate emission reductions.

[0019] In addition, CO 2 CO emission reduction calculation system 2 The business entity for which the emission reduction amount is calculated may be any business entity that consumes fuel supplied to a fuel tank and provides waste fuel removed from the fuel tank to a recycled fuel manufacturing plant as a raw material for recycled fuel, and is not limited to any business entity that discharges waste edible oil. In addition, the fuel supplied to the business entity's fuel tank is not limited to B5 fuel, and may be any fuel that contains biofuel, for example, 100% biodiesel fuel (B100) or gasoline mixed with biofuel. In addition, the biofuel is not limited to biodiesel fuel made from waste edible oil, and may be, for example, fuel directly manufactured from edible biomass (grains, etc.), or bioethanol fuel. For biofuels other than biodiesel fuel, the carbon dioxide emissions emitted when burned are theoretically counted as zero.

[0020] First Embodiment Next, the CO2 The configuration of the emission reduction calculation system 100 will be described. 2 FIG. 2 is a schematic diagram showing an example of the configuration of an emission reduction amount calculation system 100. As shown in FIG. 2 The emission reduction calculation system 100 includes a server 10, a supplier terminal 20, and a sensor 30. The sensor 30 is attached to the fuel tank of the business operator and detects when the amount of fuel in the fuel tank reaches a preset lower limit. This lower limit is the lower limit of the operational range and is set with a margin up to the amount corresponding to an empty state of the fuel tank. For example, the amount of fuel expected to be consumed over several days in an emergency is set as the lower limit.

[0021] The server 10, the supplier terminal 20, and the sensor 30 are connected to each other so as to be able to communicate with each other via a network 40. The network 40 is a communication network including wired or wireless communication lines, such as the Internet or a wireless communication line network.

[0022] The server 10 notifies the fuel supplier when to replace the fuel in the fuel tank and also calculates the CO2 emission of the business operator for a predetermined period. 2 The server 10 functions as a device for calculating the amount of emission reduction. FIG. 3 is a block diagram showing the configuration of the server 10. As shown in FIG. 3, the server 10 includes a receiving unit 11, a usable period information storage unit 12, a fuel supply date information storage unit 13, a replenishment fuel amount information storage unit 14, a fuel supply completion time fuel amount information storage unit 15, a waste fuel amount information storage unit 16, a first refueling timing notification unit 17, and a CO 2 The system includes an emission reduction calculation unit 18 and a transmission unit 19.

[0023] The server 10 is configured with a computer. This computer has a function of informing a fuel supplier of the timing to replace the fuel in the fuel tank, and a function of calculating the CO2 emission of a business entity that consumes biofuel for a predetermined period of time. 2A program for realizing the emission reduction amount calculation function is stored in the server 10. By executing this program, each function of the server 10, that is, the receiving unit 11, the usable period information storage unit 12, the fuel supply date information storage unit 13, the replenishment fuel amount information storage unit 14, the fuel amount information storage unit at the time of fuel supply completion 15, the waste fuel amount information storage unit 16, the first refueling timing notification unit 17, the CO 2 The functions of an emission reduction amount calculation unit 18, a transmission unit 19, etc. are configured.

[0024] The receiving unit 11 is connected to the supplier terminal 20, the sensor 30, etc. via the network 40, and receives, for example, information on the amount of fuel in the fuel tank transmitted from the supplier terminal 20, a detection signal transmitted from the sensor 30, etc.

[0025] The usable period information storage unit 12 stores information on the usable period. The usable period is the period from when fuel is supplied to the fuel tank until the fuel starts to deteriorate over time, and is set in advance. The usable period may be set for each fuel tank depending on the type of fuel supplied to the fuel tank and the environment of the installation location of the fuel tank. For example, since B5 fuel starts to deteriorate over time about six months after refueling, the usable period when B5 fuel is refueled into the fuel tank may be set to six months.

[0026] The fuel supply date information storage unit 13 stores information on the date on which the fuel supplier supplies fuel to the fuel tank from an empty state. In the following description, the date on which the fuel supplier supplies fuel to the fuel tank from an empty state is referred to as the "fuel supply date". The replenishment fuel amount information storage unit 14 stores information on the replenishment fuel amount, which is the amount of fuel replenished when the fuel supplier replenishes fuel to the fuel tank during the period from the fuel supply date to the refueling time. The fuel supply completion fuel amount information storage unit 15 stores information on the fuel supply completion fuel amount, which is the amount of fuel in the fuel tank at the time of completion of fuel supply when the fuel supplier supplies fuel to the empty fuel tank. The waste fuel amount information storage unit 16 stores information on the waste fuel amount, which is the amount of waste fuel removed from the fuel tank by replacing the fuel in the fuel tank.

[0027] The first fuel change timing notification unit 17 is a processing unit that notifies the supplier terminal 20 of the timing to change (replace) the fuel in the fuel tank when a previously set and stored usable period of the fuel has elapsed counting from the fuel supply date, or when a detection signal is received from the sensor 30 before the usable period has elapsed. Note that the first fuel change timing notification unit 17 may be a processing unit that notifies the supplier terminal 20 of the timing to change the fuel in the fuel tank at the earlier timing of when a usable period has elapsed counting from the fuel supply date, or when a detection signal is received from the sensor 30.

[0028] CO 2 The emission reduction calculation unit 18 calculates the first CO 2 Emission reduction calculation unit 18a and second CO 2 The first CO 2 The emission reduction amount calculation unit 18a calculates the fuel consumption amount of the business operator based on the information on the fuel amount at the time of fuel supply completion, the information on the waste fuel amount, and, if there is information on the replenishment fuel amount, the information on the replenishment fuel amount. 2 The emission reduction calculation unit 18a calculates a first CO 2 Calculate the amount of emission reduction. Second CO 2 The emission reduction calculation unit 18b calculates the second CO emission reduction amount resulting from using the waste fuel as a raw material for the regenerated fuel based on the information on the amount of the waste fuel, on the assumption that all the waste fuel is processed into the regenerated fuel. 2 Calculate the emission reductions and CO 2 The emission reduction calculation unit 18 calculates the first CO 2 Emissions reductions and second CO 2 Based on the amount of CO2 emissions reduction, the company's CO2 emissions from the time fuel is supplied to an empty fuel tank until it is removed 2 Calculate emission reductions.

[0029] The transmitting unit 19 is connected to the supplier terminal 20 and the like via the network 40, and transmits, for example, information to the supplier terminal 20 notifying that it is time to replace the fuel in the fuel tank.

[0030] The supplier terminal 20 is a terminal used by a fuel supplier, and is, for example, a PC (Personal Computer). The supplier terminal 20 includes input and display means such as a keyboard and mouse, an information storage device such as a memory, an arithmetic processing device such as a CPU, a transmitting / receiving device, and the like. The supplier terminal 20 may be a tablet terminal or a mobile terminal, and may be, for example, a terminal carried by the driver of a fuel delivery vehicle. Note that the terminal of the business operator and the terminal of the renewable fuel production plant, both of which will be described later (neither of which are shown), are configured in the same manner as the supplier terminal 20 described above, and are connected to the server 10 via the network 40.

[0031] Next, CO 2 The operation of the emission reduction calculation system 100 will be described with reference to the flowchart in FIG. 21 is a flowchart showing an example of the operation of the emission reduction calculation system 100. First, a fuel supplier supplies fuel to an empty fuel tank. For example, a fuel supplier supplies fuel to an empty fuel tank when a business operator installs a fuel tank or when fuel is removed from the fuel tank when replacing the fuel in the fuel tank. At this time, the supplier terminal 20 transmits information on the fuel supply date to the server 10 (step S01). The supplier terminal 20 also transmits information on the fuel amount at the time of fuel supply completion to the server 10 (step S02). The information on the fuel supply date and the fuel amount at the time of fuel supply completion transmitted to the server 10 in steps S01 and S02 is, for example, input to the supplier terminal 20 by the fuel supplier operating the supplier terminal 20 and transmitted to the server 10. Here, the fuel amount at the time of fuel supply completion (i.e., the amount of fuel in the fuel tank at the time of fuel supply completion) is the same amount of fuel supplied by the fuel supplier to the empty fuel tank. For this reason, the fuel supplier may input the amount of fuel supplied to the fuel tank as the fuel amount at the time of fuel supply completion. The information on the fuel supply date and the information on the fuel amount at the time of fuel supply completion are stored in the fuel supply date information storage unit 13 and the fuel amount at the time of fuel supply completion information storage unit 15, respectively.

[0032] Furthermore, when the fuel supplier refuels the fuel tank after the refueling date, information notifying the server 10 of the refueling is transmitted from the supplier terminal 20 to the server 10. The information notifying the refueling includes information on the date of the refueling and information on the amount of fuel refueled on that day (amount of refueled fuel). The information notifying the refueling is stored in the refueled fuel amount information storage unit 14.

[0033] Next, the server 10 transmits information notifying the timing of replacing the fuel in the fuel tank to the supplier terminal 20 (step S03). In step S03, the first fuel exchange timing notification unit 17 transmits information notifying the timing of replacing the fuel (for example, information instructing a fuel replacement) to the supplier terminal 20 when the pre-set and stored usable period of the fuel counting from the fuel supply date has elapsed, or when a detection signal is received from the sensor before the usable period has elapsed. Note that the time when the pre-set and stored usable period of the fuel counting from the fuel supply date has elapsed is, for example, six months after December 25, 2022, when the fuel supply date is set to December 25, 2022 and the usable period is set to six months.

[0034] For example, in step S03, the first fuel exchange timing notification unit 17 may transmit information notifying the supplier terminal 20 of the timing to replace the fuel when a previously set and stored usable period of the fuel has elapsed, calculated from the fuel supply date stored in the fuel supply date information storage unit 13. In this case, if a detection signal is received from the sensor before the usable period of the fuel has elapsed (i.e., when the amount of fuel in the fuel tank has reached a lower limit), information notifying the supplier terminal 20 of the timing to refuel (e.g., information instructing refueling) may be transmitted to the supplier terminal 20. Also, in step S03, the first fuel exchange timing notification unit 17 may transmit information notifying the supplier terminal 20 of the timing to replace the fuel in the fuel tank, either when a previously set and stored usable period of the fuel has elapsed, calculated from the fuel supply date, or when a detection signal is received from the sensor 30, whichever is earlier. In other words, when the amount of fuel in the fuel tank reaches the lower limit before the non-deteriorating period of the fuel has elapsed, the first fuel change timing notification unit 17 may transmit information notifying the supplier terminal 20 of the timing to change the fuel in the fuel tank at that timing. Note that when transmitting the information notifying the timing of fuel change to the supplier terminal 20, the first fuel change timing notification unit 17 may also transmit the information to the business operator's terminal to notify the business operator of the timing of fuel change.

[0035] Following step S03, the server 10 acquires fuel quantity information of the discarded fuel (step S04). That is, in step S04, the server 10 acquires information on the amount of discarded fuel removed from the fuel tank when replacing the fuel (hereinafter referred to as "discarded fuel amount"). The discarded fuel amount may be measured, for example, when the fuel is replaced, or may be calculated from the weight difference before and after unloading a transport vehicle carrying the discarded fuel, since the discarded fuel is transported to a recycled fuel production plant. In this case, the server 10 receives information on the discarded fuel amount transmitted from, for example, the supplier terminal 20, the business operator terminal, or a terminal of the recycled fuel production plant, and stores the received information on the discarded fuel amount in the discarded fuel amount information storage unit 16.

[0036] Following step S04, the server 10 2 The emission reduction amount is calculated (step S05). In step S05, first, the first CO 2 The emission reduction calculation unit 18a calculates the amount of fuel consumed by the business operator during a predetermined period. Specifically, if the fuel tank is not refueled during the period from the fuel supply date to the fuel replacement date (i.e., if there is no information on the refueled fuel amount in the refueled fuel amount information storage unit 14), the first CO 2 The emission reduction calculation unit 18a calculates the fuel consumption of the business operator during the above period by subtracting the amount of waste fuel from the amount of fuel at the time of fuel supply completion. 2 The emission reduction amount calculation unit 18a calculates the fuel consumption amount of the business operator during the above-mentioned period by adding the replenishment fuel amount to a value obtained by subtracting the waste fuel amount from the fuel amount at the time of fuel supply completion. 2 The emission reduction calculation unit 18a calculates a first CO 2 Calculate emission reductions.

[0037] For example, if a fuel supplier fills an empty fuel tank of an operator with 1,000 liters of B5 fuel, and then, without refueling, 500 liters of waste fuel is removed from the fuel tank by replacing the fuel in the fuel tank, the operator's fuel consumption is first calculated as 500 liters by subtracting the amount of waste fuel (500 liters) from the amount of fuel at the completion of fuel supply (1,000 liters). Next, 5% of the 500 liters of B5 fuel consumed by the business is biofuel, so the carbon dioxide emissions are theoretically counted as zero. Therefore, in the above case, the first CO 2 The reduction in emissions is calculated based on the fuel consumption (500 liters), the proportion of biofuel (5%), and the CO 2 Emission factor (2.58 kg CO 2 This is calculated by multiplying this by 1 / L (liters) and gets you 64.5kg. In other words, the carbon dioxide emissions when 500 liters of 100% diesel fuel is consumed are the sum of the fuel consumption (500 liters) and the CO 2 The carbon dioxide emissions from consuming 500 liters of B5 fuel are calculated by multiplying the fuel consumption, the proportion of biofuel, and the CO2 emissions from diesel. 2 In this case, the business operator has reduced carbon dioxide emissions by 64.5 kg, which is the difference between the amount of carbon dioxide emissions when 500 liters of 100% diesel fuel is consumed and the amount of carbon dioxide emissions when 500 liters of B5 fuel is consumed, i.e., 1,290 kg and 1,225.5 kg.

[0038] Following step S05, the server 10 2 The emission reduction amount is calculated (step S06). In step S06, the second CO 2 The emission reduction calculation unit 18b calculates a second CO 2 Calculate emission reductions.

[0039] In the above example, the amount of waste fuel is 500 liters of B5 fuel. This waste fuel is not incinerated but processed into recycled fuel and recycled. Therefore, the amount of CO 2 Emissions are the second CO2 from using waste fuel as a raw material for renewable fuels. 2 This corresponds to the amount of CO2 emissions reduced. 2 The emission reduction amount is the amount of B5 fuel, which is waste fuel, excluding biofuel, i.e., 95% (475 liters) of the waste fuel amount, plus CO2 from diesel. 2 In the above example, the second CO 2 The emission reduction amount will be 1,225.5 kg.

[0040] Next, the server 10 receives the operator's CO 2 Calculate the emission reduction amount (step S07). In step S07, CO 2 The emission reduction calculation unit 18 calculates the first CO 2 Emissions reductions and second CO 2 Based on the amount of CO2 emissions reduction, the company's CO2 emissions from the time fuel is supplied to an empty fuel tank until it is removed 2 The amount of emission reduction is calculated. Although not shown in the figure, the server 10 calculates the CO 2 Information on the amount of emission reductions is sent to the business operator's terminal.

[0041] For example, CO 2 The emission reduction calculation unit 18 calculates the first CO 2 Emissions reductions and second CO 2 Add the emission reductions to the total CO 2 Calculate the emission reduction amount. In the above example, the first CO 2 Emission reduction of 64.5 kg, second CO 2 The emission reduction is 1,225.5 kg, so CO 2 The emission reduction amount will be 1,290 kg.

[0042] Figure 5 shows the CO 25 is a diagram showing an example of information on the amount of emission reduction. In the example shown in FIG. 5, the (current) fuel exchange date and the previous fuel exchange date are displayed, and the CO2 reduction amount of the company during the period from the previous fuel exchange date to the (current) fuel exchange date is displayed. 2 The amount of emission reduction is displayed. In this case, the usable period is set to six months, and fuel exchange is performed when the usable period has elapsed without receiving a detection signal from the sensor.

[0043] That's all, CO 2 The operation of the emission reduction calculation system 100 has been described. 2 The operation of the emission reduction calculation system 100 is not limited to the above. For example, each of steps S01 to S07 in the flowchart shown in Fig. 4 may be executed in an order different from that shown in the figure, or multiple steps S01, etc. may be executed simultaneously. Also, some of the steps shown in the figure may be omitted.

[0044] CO according to the first embodiment 2 According to the emission reduction calculation system 100, the CO 2 Calculate the amount of CO emissions reduction. 2 Using the emission reduction figures, 2 The results of emission reduction efforts can be quantitatively visualized, and businesses can then use the calculated CO 2 By using the numerical value of emission reduction, 2 The results of our emissions reduction efforts can be publicly promoted.

[0045] In addition, CO 2According to the emission reduction calculation system 100, if the server 10 is configured to transmit information to the supplier terminal 20, etc., notifying the timing of replacing the fuel in the fuel tank when a previously set and stored usable period of the fuel has elapsed, counting from the date of fuel supply, or when a detection signal is received from the sensor 30, whichever is earlier, the server 10 will transmit information notifying the timing of replacing the fuel if the amount of fuel in the fuel tank reaches a lower limit before the usable period has elapsed, and by replacing the fuel at this timing, the amount of wasted fuel can be reduced.

[0046] <Second embodiment> Next, a second embodiment will be described. In the description of the second embodiment, the same or equivalent components as those in the first embodiment will be denoted by the same reference numerals, and the description will be omitted or simplified. 2 The emission reduction calculation system includes a server 210 (see FIG. 6), a supplier terminal 20, and a sensor 30. The server 210, the supplier terminal 20, and the sensor 30 are connected via a network 40 so as to be able to communicate with each other.

[0047] The server 210 notifies the operator when to replace the fuel in the fuel tank and also displays the CO2 emission of the operator for a specified period. 2 It functions as a device for calculating the amount of CO emission reduction. 2 6 is a block diagram showing the configuration of a server 210 of the emission reduction calculation system. As shown in FIG. 6, the server 210 includes a receiving unit 11, a usable period information storage unit 12, a fuel supply date information storage unit 13, a replenishment fuel amount information storage unit 14, a fuel supply completion time fuel amount information storage unit 15, a waste fuel amount information storage unit 16, and a CO 2 The device includes an emission reduction calculation unit 18, a transmission unit 19, a fuel consumption actual data storage unit 41, a fuel consumption prediction unit 42, a lower limit fuel amount information storage unit 43, a consumable fuel amount calculation unit 44, a refueling determination unit 45, and a second refueling timing notification unit 46.

[0048] The server 210 is configured with a computer. This computer has a function of informing a fuel supplier of the timing to replace the fuel in the fuel tank, and a function of calculating the CO2 emission amount for a given period of time of a business entity that consumes biofuel. 2 A program for realizing the emission reduction amount calculation function is stored in the server 210. By executing this program, each function of the server 210, that is, the receiving unit 11, the usable period information storage unit 12, the fuel supply date information storage unit 13, the replenishment fuel amount information storage unit 14, the fuel supply completion fuel amount information storage unit 15, the waste fuel amount information storage unit 16, the CO 2 The system is configured with functions such as an emission reduction calculation unit 18, a transmission unit 19, a fuel consumption actual data storage unit 41, a fuel consumption prediction unit 42, a lower limit fuel amount information storage unit 43, a consumable fuel amount calculation unit 44, a refueling determination unit 45, and a second refueling timing notification unit 46.

[0049] The fuel consumption performance data storage unit 41 stores the performance data of the fuel consumption of the company in the past. 2 The data includes data on the fuel consumption of the business operator for a specified period calculated by the emission reduction calculation unit 18a, and is, for example, data that links information on the fuel usage period (the period from the fuel supply date to the fuel exchange) with the fuel consumption of the business operator for that usage period.

[0050] The fuel consumption prediction unit 42 is a processing unit that predicts the amount of fuel consumed by the business operator during the period from the fuel supply date until the expiration of the usable period of the fuel, based on the past data of the fuel consumption.

[0051] The lower limit fuel amount information storage unit 43 stores information on the lower limit fuel amount. The lower limit fuel amount is the amount of fuel in the fuel tank when the fuel in the fuel tank is at the lower limit, in other words, the amount of fuel supplied when fuel is supplied to an empty fuel tank until the amount reaches the lower limit.

[0052] The consumable fuel amount calculation unit 44 is a processing unit that calculates the consumable fuel amount. The consumable fuel amount refers to the amount of fuel that is permitted to be consumed out of the amount of fuel in the fuel tank when fuel supply is completed, and specifically refers to the amount of fuel in the fuel tank that exceeds the lower limit amount of the fuel tank when fuel supply is completed. The consumable fuel amount calculation unit 44 calculates the consumable fuel amount, for example, by subtracting the lower limit amount of fuel from the amount of fuel at the time of fuel supply completion.

[0053] The refueling determination unit 45 is a processing unit that determines whether or not it is necessary to refuel the fuel tank before the expiration of a previously set and stored usable period of the fuel, calculated from the fuel supply date. If the refueling determination unit 45 determines that refueling is necessary, it calculates the amount of fuel that needs to be refueled before the usable period expires (hereinafter referred to as the "amount of fuel required for refueling") and transmits information on the calculated amount of fuel required for refueling to the supplier terminal 20.

[0054] When the refueling determination unit 45 determines that refueling is not necessary, the second refueling timing notification unit 46 notifies the supplier terminal 20 of the timing to replace (change) the fuel in the fuel tank at the same timing as the above-mentioned first refueling timing notification unit 17. On the other hand, when the refueling determination unit 45 determines that refueling is necessary, the second refueling timing notification unit 46 notifies the supplier terminal 20 of the timing to replace the fuel in the fuel tank at the earlier of when the usable period has elapsed counting from the fuel supply date, or when a detection signal is received from the sensor 30 after refueling of the amount of fuel required for refueling calculated by the refueling determination unit 45 has been completed.

[0055] Next, the second embodiment of the CO 2 The operation of the emission reduction calculation system will be described with reference to the flowchart in FIG. 7. 21 is a flowchart showing an example of the operation of the emission reduction calculation system. First, a fuel supplier supplies fuel to an empty fuel tank. At this time, the supplier terminal 20 transmits information on the fuel supply date to the server 210 (step S11). In addition, the supplier terminal 20 transmits information on the amount of fuel at the time of completion of fuel supply to the server 210 (step S12). The operations of steps S11 and S12 are similar to the operations of steps S01 and S02 described above.

[0056] Following step S12, the server 210 calculates the consumable fuel amount in the fuel tank (step S13). In step S13, for example, the consumable fuel amount calculation unit 44 calculates the consumable fuel amount by subtracting the lower limit fuel amount from the fuel amount at the time of fuel supply completion. For example, when the fuel amount at the time of fuel supply completion is 1,000 liters and the lower limit fuel amount is 100 liters, the consumable fuel amount calculation unit 44 calculates the consumable fuel amount to be 900 liters.

[0057] The server 210 also predicts the fuel consumption (step S14). In step S14, the fuel consumption prediction unit 42 predicts the fuel consumption of the business entity from the fuel supply date until the expiration of the usable period of the fuel based on the actual fuel consumption data. For example, if the preset usable period is six months and the actual fuel consumption data shows that the business entity consumed 1,200 liters of fuel in six months, the fuel consumption prediction unit 42 predicts the predicted fuel consumption of the business entity from the fuel supply date until the expiration of the usable period to be 1,200 liters.

[0058] Next, the server 210 judges whether or not refueling is necessary (step S15). In step S15, the refueling judgment unit 45 judges whether or not it is necessary to refuel the fuel tank from the fuel supply date until the expiration of the usable period of the fuel. The refueling judgment unit 45 judges this based on, for example, the consumable fuel amount in the fuel tank calculated in step S13 and the predicted fuel consumption amount of the business operator predicted in step S14. Specifically, when the predicted fuel consumption amount is less than the consumable fuel amount, or when the predicted fuel consumption amount and the consumable fuel amount are the same, the refueling judgment unit 45 judges that refueling is unnecessary. When the refueling judgment unit 45 judges that refueling is unnecessary, steps S16 and S17 are not executed, and the process proceeds to step S18. On the other hand, when the predicted fuel consumption amount exceeds the consumable fuel amount, the refueling judgment unit 45 judges that refueling is necessary.

[0059] In step S15, if the refueling determination unit 45 determines that refueling is necessary, the server 210 transmits information on the amount of fuel required for refueling to the supplier terminal 20 (step S16). In step S16, the refueling determination unit 45 calculates the amount of fuel that needs to be refueled before the usable period expires, and transmits information on the calculated amount of fuel required for refueling to the supplier terminal 20. Here, the amount of fuel that needs to be refueled (amount of fuel required for refueling) is the amount of fuel that corresponds to the difference between the predicted fuel consumption amount and the consumable fuel amount. For example, when the predicted fuel consumption amount is 1,200 liters and the consumable fuel amount is 900 liters, the predicted fuel consumption amount exceeds the consumable fuel amount, so the refueling determination unit 45 determines that refueling is necessary and transmits information to the supplier terminal 20 notifying that the amount of fuel required for refueling is 300 liters.

[0060] After step S16, when the fuel supplier completes refueling, the supplier terminal 20 transmits information notifying the completion of refueling (e.g., information on the refueling date, information on the amount of fuel refueled, etc.) to the server 210 (step S17). At this time, the information notifying the completion of refueling is, for example, input to the supplier terminal 20 by the fuel supplier operating the supplier terminal 20 and transmitted to the server 210. The information on the amount of refueled fuel received by the server 210 is stored in the refueled fuel amount information storage unit 14. Note that, in cases such as when the amount of fuel required for refueling exceeds the capacity of the fuel tank, the fuel supplier refuels in multiple batches. In this case, when the entire amount of fuel required for refueling has been refueled, the supplier terminal 20 transmits information notifying the completion of refueling (hereinafter referred to as "refueling completion notification information") to the server 210.

[0061] Following step 17 (or step 15), the server 210 transmits information notifying the timing of replacing the fuel in the fuel tank to the supplier terminal 20 (step S18). Specifically, if the refueling determination unit 45 determines in step S15 that refueling is not necessary, the second refueling timing notification unit 46 transmits information notifying the timing of replacing the fuel in the fuel tank to the supplier terminal 20 at the earlier timing of when the usable period of the fuel has elapsed from the fuel supply date or when a detection signal is received from the sensor 30. On the other hand, if the refueling determination unit 45 determines in step S15 that refueling is necessary, the second refueling timing notification unit 46 notifies the supplier terminal 20 of the timing of replacing the fuel in the fuel tank at the earlier timing of when the usable period of the fuel has elapsed from the fuel supply date or when a detection signal is received from the sensor 30 after the refueling completion information is received (step S17). The server 210 may transmit information notifying the timing of refueling to the supplier terminal 20 when it receives a detection signal from the sensor 30 before, rather than after, receiving the refueling completion information.

[0062] Following step S18, the server 210 acquires information on the amount of waste fuel (step S19).2 Emission reductions and secondary CO 2 Calculate the emission reduction amount for each business (step S20, step S21) and calculate the CO 2 The emission reduction amount is calculated (step S22). The operations in steps S19 to S22 are similar to those in steps S04 to S07 described above.

[0063] CO according to the second embodiment 2 The operation of the emission reduction calculation system has been explained. 2 The operation of the emission reduction calculation system is not limited to the above. For example, steps S11 to S22 in the flowchart shown in Fig. 7 may be executed in an order different from that shown in the figure, or multiple steps S11, etc. may be executed simultaneously. Also, some of the steps shown in the figure may be omitted.

[0064] The above-described CO according to the second embodiment 2 The emission reduction calculation system also uses the above-mentioned CO 2 The same effects as those of the emission reduction calculation system 100 are achieved. 2 When the emission reduction calculation system determines that the predicted fuel consumption amount exceeds the consumable fuel amount, the information on the amount of fuel required for replenishment is transmitted to the supplier terminal 20. 2 According to the configuration of the emission reduction calculation system, by replenishing the fuel with the required amount of fuel, the timing when the fuel in the fuel tank is consumed and reaches the lower limit amount can be delayed until the usable period has elapsed. Therefore, according to the second embodiment, the amount of wasted fuel can be reduced and fuel replacement can be performed less frequently.

[0065] <Third embodiment> Next, a third embodiment will be described. In the following description, the same or equivalent components as those in the first or second embodiment will be denoted by the same reference numerals, and the description thereof will be omitted or simplified. 2The emission reduction calculation system includes a server 310 (see FIG. 8), a supplier terminal 20, and a sensor 30. The server 310, the supplier terminal 20, and the sensor 30 are connected via a network 40 so as to be able to communicate with each other.

[0066] The server 310, like the servers 10 and 210 described above, notifies the fuel supplier of the timing to replace the fuel in the fuel tank and also records the CO2 emissions of the company for a predetermined period. 2 The server 310 functions as a device for calculating the amount of emission reduction. The server 310 also functions as a device for calculating the amount of fuel that can be delivered to the fuel tank in an emergency.

[0067] Fig. 8 is a block diagram showing the configuration of the server 310. As shown in Fig. 8, the server 310 includes a receiving unit 11, a usable period information storage unit 12, a fuel supply date information storage unit 13, a replenishment fuel amount information storage unit 14, a fuel supply completion time fuel amount information storage unit 15, a waste fuel amount information storage unit 16, a first refueling timing notification unit 17, and a CO 2 The system includes an emission reduction amount calculation unit 18, a transmission unit 19, a fuel consumption performance data storage unit 41, a fuel consumption amount prediction unit 47 until an emergency, and a deliverable fuel amount calculation unit .

[0068] The server 310 is configured with a computer. This computer has a function of informing a fuel supplier of the timing to replace the fuel in the fuel tank, and a function of calculating the CO2 emission amount for a predetermined period of time of a business entity that consumes biofuel. 2 A program for realizing the emission reduction amount calculation function is stored in the server 310. By executing this program, each function of the server 310, that is, the receiving unit 11, the usable period information storage unit 12, the fuel supply date information storage unit 13, the replenishment fuel amount information storage unit 14, the fuel supply completion fuel amount information storage unit 15, the waste fuel amount information storage unit 16, the first refueling timing notification unit 17, the CO 2 The system is made up of an emission reduction amount calculation unit 18, a transmission unit 19, a fuel consumption performance data storage unit 41, a fuel consumption amount prediction unit 47 until an emergency, a deliverable fuel amount calculation unit 48, and the like.

[0069] The fuel consumption until emergency prediction unit 47 is a processing unit that predicts the fuel consumption of the business operator during the period from the fuel supply date to the time of receiving the emergency notification information (hereinafter referred to as "fuel consumption until emergency") when the server 310 receives information (hereinafter referred to as "emergency notification information") notifying the business operator that an emergency occurs when the use of the private generator is essential. In other words, the fuel consumption until emergency prediction unit 47 predicts how much fuel the business operator has consumed during the normal period leading up to the emergency. The fuel consumption until emergency prediction unit 47 predicts the fuel consumption of the business operator during the above-mentioned period based on the actual fuel consumption data.

[0070] The deliverable fuel amount calculation unit 48 is a processing unit that calculates the deliverable fuel amount. The deliverable fuel amount is the amount of fuel that can be replenished to the fuel tank in an emergency. The deliverable fuel amount calculation unit 48 calculates the deliverable fuel amount based on information on the fuel consumption amount up to the emergency predicted by the fuel consumption prediction unit 47 and information on the replenishment fuel amount. For example, the deliverable fuel amount calculation unit 48 calculates the deliverable fuel amount by subtracting the replenishment fuel amount from the fuel consumption amount up to the emergency. However, if refueling has not been performed after the fuel supply date, the deliverable fuel amount is the same as the fuel consumption amount up to the emergency.

[0071] In the event of an emergency, such as a power outage, businesses operate private generators to secure power sources, so the demand for fuel in fuel tanks increases significantly compared to normal times. In such an emergency, fuel suppliers are required to refuel fuel tanks quickly, and in particular, when delivering fuel to multiple fuel tanks, it is necessary to deliver the fuel efficiently.

[0072] Next, the third embodiment of the CO 2 The operation of the emission reduction calculation system according to the third embodiment will be described. 2 The emission reduction calculation system is the CO 2 Like the emission reduction calculation system 100, each step (S01 to S07) of the flowchart in FIG. 4 is executed, but in an emergency, processing such as notifying the supplier terminal 20 of the deliverable fuel amount is also executed.

[0073] Therefore, the third embodiment of the CO 2 The operation of the emission reduction calculation system in an emergency will be described with reference to the flowchart in FIG. 2 A flowchart showing an example of an operation of the emission reduction calculation system in an emergency. After the processing of steps S01 and S02 (see FIG. 4), when an emergency occurs in which the use of a private generator is essential for a business, the business's terminal transmits information notifying the server 310 of the emergency, as shown in FIG. 9 (step S31). In step S31, for example, when a power outage occurs due to a natural disaster or accident in a business such as a restaurant or food factory, the business's terminal transmits information to the server 310 notifying the server 310 that the business is in an emergency and the use of a private generator is essential, together with information identifying the business that has experienced a power outage (for example, the business's name or ID). Note that the source of the information notifying the emergency in step S31 is not limited to the business's terminal, and may be, for example, the supplier terminal 20. In addition, the information notifying the emergency is not limited to information transmitted from the terminal, and may be, for example, an emergency alert when a power outage occurs.

[0074] When the server 310 receives the information notifying the emergency in step S31, it predicts the fuel consumption until the emergency (step S32). In step S32, the fuel consumption until emergency prediction unit 47 predicts the fuel consumption until the emergency based on the actual fuel consumption data of the business operator. For example, if the period from the fuel supply date to the time when the information notifying the emergency is received is three months, and the actual fuel consumption data shows that the business operator consumed 1,200 liters of fuel in six months, the fuel consumption until emergency prediction unit 42 predicts the fuel consumption until the emergency to be 600 liters.

[0075] Following step S32, server 310 calculates the deliverable fuel amount (step S33). In step S33, deliverable fuel amount calculation unit 48 calculates the deliverable fuel amount to the fuel tank based on information including information on the fuel consumption amount until the emergency. For example, if the predicted fuel consumption amount until the emergency is 600 liters and the replenishment fuel amount is 200 liters, deliverable fuel amount calculation unit 48 calculates the deliverable fuel amount to be 400 liters.

[0076] Following step S33, the server 310 transmits information on the deliverable fuel amount to the supplier terminal 20 (step S34). When the fuel supplier refuels the fuel tank, information notifying the server 10 that refueling has occurred is transmitted from the supplier terminal 20 to the server 10. The information notifying the server 10 that refueling has occurred includes information on the date of refueling and information on the amount of fuel refueled on that day (amount of refueled fuel). The information notifying the server 10 that refueling has occurred is stored in the refueled fuel amount information storage unit 14.

[0077] The above-described CO according to the third embodiment 2 The emission reduction calculation system also uses the above-mentioned CO 2 The same effects as those of the emission reduction calculation system 100 are achieved. 2 The emission reduction calculation system transmits information on the amount of fuel that can be delivered in an emergency to the supplier terminal 20. Therefore, particularly in cases where a fuel supplier supplies fuel to the fuel tanks of multiple businesses, the fuel supplier can use the information on the amount of fuel that can be delivered to efficiently deliver (transport) fuel to each of the fuel tanks of the multiple businesses.

[0078] Although the embodiments of the present invention have been described above, the technical scope of the present invention 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 spirit of the present invention. Furthermore, one or more of the requirements described in the above embodiments may be omitted. Such modifications, improvements, and omitted forms are also included in the technical scope of the present invention. Furthermore, the configurations of the above embodiments can be applied in appropriate combination. For example, the CO2 The emission reduction calculation system may be configured to have an emergency processing function according to the third embodiment. [Explanation of symbols]
