Abstract
Description
[Technical Field]
[0001] The present invention relates to a greenhouse gas emission reduction supply and demand management system for sewage treatment facilities and a method for managing supply and demand of greenhouse gas emission reductions at sewage treatment facilities, and in particular to a greenhouse gas emission reduction supply and demand management system for sewage treatment facilities and a method for managing supply and demand of greenhouse gas emission reductions at sewage treatment facilities that predict the demand for greenhouse gas emission reductions at facilities that have not achieved a specified greenhouse gas emission reduction amount, and match this with the surplus amount at facilities that have achieved the specified greenhouse gas emission reduction amount. [Background technology]
[0002] In order to curb global warming, it is urgent to reduce greenhouse gas emissions such as carbon dioxide, methane, and zinc nitride, and efforts are being made by countries, local governments, and even companies to curb and reduce emissions. To promote the reduction of greenhouse gas emissions, an emissions trading system has been established, which allows companies to curb and reduce apparent emissions by buying and selling the right to emit greenhouse gases (emissions credits). The emissions trading system is a mechanism in which companies that have achieved reductions in greenhouse gas emissions that exceed their target reduction amounts, based on the greenhouse gas emission allowances set for each country or company, and companies that are unable to achieve their target reduction amounts, buy and sell the excess or shortfall.
[0003] In these circumstances, a system is known that tracks greenhouse gas emissions and predicts final emissions. If emissions exceed the target, the system compares the options of obtaining emission credits from the trading market or reducing factory operations to reduce emissions from the perspective of corporate profitability, thereby supporting management decisions. The Ministry of the Environment has advocated carbon pricing as a policy method to put a price on carbon and change emitters' behavior. The main types of carbon pricing include carbon taxes, which impose a proportional tax on fuel and electricity use (CO2 emissions); domestic emissions trading, in which emissions are capped for each company and traded between companies that exceed and fall below the cap; credit trading, in which CO2 reduction value is documented and traded; market mechanisms operated by international organizations; and internal carbon pricing, in which companies independently price their own CO2 emissions and use them for investment decisions. The Japanese government operates non-fossil value trading, the J-Credit Scheme, and the JCM (Joint Crediting Mechanism). An example of the J-Credit System is the carbon credit market that the Tokyo Stock Exchange opened on October 11, 2023.
[0004] A proposed system for managing emission credits, such as J-Credits, includes a user terminal operated by a user who submits emission credits and a management server that manages the emission credits submitted by the user. The user terminal transmits basic emission credit data related to the emission credits to the management server. The management server, upon receiving the basic emission credit data from the user terminal, generates emission credit trading data by converting the emission credits indicated in the basic emission credit data into credits based on the received basic emission credit data. The system then determines the recipient of business support using emission credit trading based on the support objective specified by the user (see Patent Document 1). In this system, the basic emission credit data includes the amount of solar power generation, the amount of power generation obtained by subtracting the amount of power sold from the amount of power generated, or the amount of power reduced by installing LEDs. The emission credit trading data calculates the amount of greenhouse gas reduction based on the basic emission credit data, which is the amount of power, and is then calculated based on the calculated amount of greenhouse gas reduction. The management server matches the support objective of the user who creates the emission credits with the business content of the business that receives business support using the profits from the sale of the emission credits.
[0005] As a system for supplying electricity suitable for electricity consumers by appropriately selecting a power generation type in response to information requested by the electricity consumer, an electricity supply method has been proposed in which a computer managed by an intermediary company that instructs electricity suppliers to supply electricity receives, from the electricity consumer, designation information including information on the electricity supply ratio of the power generation type requested by the electricity consumer from multiple power generation types (solar power generation, thermal power generation, nuclear power generation, hydroelectric power generation, wind power generation, geothermal power generation, biomass power generation, waste plastic power generation, etc.), automatically selects, from the multiple power generation types, a power generation type that can achieve the electricity supply ratio according to the designation information, and instructs the electricity supplier that supplies electricity obtained from the selected power generation type to supply electricity to the electricity consumer (Patent Document 2).The computer managed by the intermediary company matches the power generation types of the electricity consumer and the electricity supplier.

[0008] Because wastewater treatment plants generate large amounts of greenhouse gases, particularly CO2, reducing CO2 emissions is an urgent issue. Sewage treatment plants consist of pipelines, pumping facilities, water treatment facilities, and sludge treatment facilities, and are equipped with equipment that consumes power, such as pumps, blowers, thickeners, and dehydrators. Emission credits can be generated by reducing power consumption through measures such as reducing the power consumed (energy conservation measures), switching to renewable energy (renewable energy utilization), generating electricity using methane gas from anaerobic treatment plants, and converting dehydrated cake produced at sludge treatment plants into solid fuel (energy creation). Facilitating and popularizing the trading of emission credits based on the amount of greenhouse gas emissions reduced at wastewater treatment plants is expected to motivate technological development for reducing greenhouse gases at wastewater treatment plants and contribute to further greenhouse gas reductions.
[0009] An object of the present invention is to provide a system and method for managing supply and demand of greenhouse gas emission reductions at a sewage treatment facility, and in particular, to provide a system and method for managing supply and demand of greenhouse gas emission reductions at a sewage treatment facility that predicts the demand for greenhouse gas emission reductions at facilities that have not achieved a predetermined greenhouse gas emission reduction amount, and matches this with the surplus amount at facilities that have achieved the predetermined greenhouse gas emission reduction amount.

It is preferably determined by
[0016] The terms used in this application will be explained below. "Sewage treatment facility" means a sewage treatment facility equipped with at least a water treatment facility, a sludge treatment facility, and a deodorization facility. "Greenhouse gases" refers to carbon dioxide (CO2), methane, nitrous oxide (N2O), hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride, which are emitted from wastewater treatment plants. "Greenhouse gas emissions" refers to the sum of direct greenhouse gas emissions, which are the greenhouse gas emissions emitted from each piece of equipment at a sewage treatment facility, and energy-related greenhouse gas emissions resulting from the electricity, gas, fuel, and heat used to operate each piece of equipment at a sewage treatment facility. "Greenhouse gas emission reductions" refers to the amount of greenhouse gases that have been reduced as a result of implementing greenhouse gas emission reduction measures at a sewage treatment facility, compared to the "greenhouse gas emissions" at that facility before the measures were implemented. "Supplier-side greenhouse gas emission reduction information" refers to information on the surplus "greenhouse gas emission reduction amount" that exceeds the target value and information on sewage treatment facilities that can supply the surplus amount. "Information on the demand-side greenhouse gas emission reduction requirements" refers to the shortfall in the "greenhouse gas emission reductions" that is necessary to reach the target value, and information on the demand side that will make up the shortfall. [Effects of the Invention]
[0017] According to the present invention, a greenhouse gas emission reduction supply and demand management system and a greenhouse gas emission reduction supply and demand management method for a sewage treatment facility are provided, which predict the demand for greenhouse gas emission reductions on the demand side, such as sewage treatment facilities and businesses that have not achieved a specified greenhouse gas emission reduction amount, and match this with the surplus amount at sewage treatment facilities that have achieved the specified greenhouse gas emission reduction amount.
[0018] Greenhouse gases are a resource for wastewater treatment plants, and the resulting greenhouse gas emission reductions create economic value in the market, motivating further greenhouse gas reductions and contributing to decarbonization and carbon neutrality at wastewater treatment plants and other facilities.
[0019] Sewage treatment facilities are often managed and operated by local governments. According to the system and method of the present invention, the greenhouse gas emission reductions achieved at a sewage treatment facility can be allocated and effectively utilized to meet the greenhouse gas emission reduction needs of facilities that have not yet achieved the required greenhouse gas emission reductions, such as businesses in the sewage collection area of the facility or facilities of the local government that manages and operates the facility. The greenhouse gas emission reductions at each sewage treatment facility and the facilities with high greenhouse gas emissions can be identified, and by reflecting this information in plans for the renewal and renovation of sewage treatment facilities aimed at decarbonization, it can contribute to further decarbonization and carbon neutrality.
[0020] Greenhouse gas emission reductions have economic value in the market and contribute to the stabilization of sewerage business management. In particular, when trading greenhouse gas emission reductions within a municipality, the transaction is completed within the municipality, which is advantageous for the management of the municipality. When trading greenhouse gas emission reductions between a municipality and another municipality, it is clear which equipment in the sewage treatment facility contributed to the greenhouse gas emission reductions, allowing other purchasing municipalities to trade with peace of mind.

Preferred Embodiments
[0022] Figure 1 shows the overall structure of a sewage treatment facility and its positioning as a sewage treatment plant. A sewage treatment facility consists of a pipeline system that transports sewage to the sewage treatment plant, and the sewage treatment plant itself. Pipe systems include sewer pipes and pumping stations. Sewage treatment plants include water treatment facilities, deodorization facilities, and sludge treatment facilities. Water treatment facilities include aerobic water treatment facilities and anaerobic water treatment facilities. Sludge treatment facilities include sludge concentration facilities and sludge dewatering facilities. In addition, sludge treatment plants may also have facilities for drying the dehydrated cake after sludge treatment, as well as incineration facilities, melting facilities, and composting facilities.
[0023] In the present invention, the supply and demand adjustment is targeted at greenhouse gas emission reductions from sewage treatment facilities that have at least water treatment facilities, sludge treatment facilities, and deodorization facilities, but this does not exclude supply and demand adjustments for greenhouse gas emissions from other facilities or auxiliary facilities of sewage treatment facilities.
[0024] FIG. 2 shows an outline of the main components of the greenhouse gas emission reduction supply and demand system of the present invention. The greenhouse gas emission reduction supply and demand system of the present invention comprises a supply-side terminal 10 that inputs supply-side greenhouse gas emission reduction amount information and outputs the collation result, a demand-side terminal 20 that inputs demand-side greenhouse gas emission reduction required information and outputs the collation result, an information processing means 30 that collects information from the supply-side terminal 10 and the demand-side terminal 20, compares the supply and demand information to match supply and demand, and provides the matching result, and electronic information transmission means 42, 44, 46, 48 that transmit information between the supply-side terminal 10, the demand-side terminal 20, and the information processing means 30.
[0025] The information processing means 30 includes an information storage unit 32 that records supply-side greenhouse gas emission reduction amount information and demand-side greenhouse gas emission reduction requirement information collected via electronic information communication means 42, 44; a matching identification processing unit 34 that compares the supply-side greenhouse gas emission reduction amount information with the demand-side greenhouse gas emission reduction requirement information to identify one or more supply-side greenhouse gas emission reduction amount information that matches the demand-side greenhouse gas emission reduction requirement information; and a matching result issuing unit 36 that issues a matching identification result to the identified combination of supply-side terminal and demand-side terminal.
[0026] The electronic information transmission means 42, 44, 46, 48 are not particularly limited as long as they are capable of transmitting electronic information, such as wired or wireless Internet, intranet, WAN, LAN, etc. The information processing means 30 may be any means capable of performing the above-mentioned predetermined information processing function, and may be a cloud server. When supply and demand of greenhouse gas emission reductions are carried out within the same sewage treatment facility, it may be a computer installed within the sewage treatment facility.
[0027] The matching specification processing unit 34 matches the supply-side greenhouse gas emission reduction amount information recorded in the information storage unit 32 with the demand-side greenhouse gas emission reduction requirement information, and specifies one or more supply-side greenhouse gas emission reduction amount information that matches one or more demand-side greenhouse gas emission reduction requirement information. If a one-to-one match between the supply side and the demand side is not possible, the matching specification processing unit 34 specifies multiple supply sides that satisfy the demand-side greenhouse gas emission reduction requirement information, or multiple demand-side greenhouse gas emission reduction requirement information that matches the supply-side greenhouse gas emission reduction amount information.
[0028] The matching result issuing unit 36 issues a matching identification result to each of the supply side terminal 10 and the demand side terminal 20 of the combination identified by the matching identification processing unit 34. The issued matching identification result is sent to the demand side terminal 20 via electronic information transmission means 46 and to the supply side terminal 10 via electronic information transmission means 48.
[0029] The supply-side greenhouse gas emission reduction information stored in the information storage unit 32 of the information processing means 30 includes at least the actual and predicted greenhouse gas emission reduction amounts at the sewage treatment facility. The supply-side greenhouse gas emission reduction information stored in the information storage unit 32 of the information processing means 30 can also include, in addition to the actual and predicted greenhouse gas emission reduction amounts, traceability information such as the reduction method implemented, the location and equipment where the reduction was performed, and the period during which the greenhouse gas emission reduction amount can be supplied.
[0030] In sewage treatment facilities, greenhouse gases are generated in each treatment facility and are emitted either directly or after treatment. Greenhouse gas emissions within a sewage treatment facility are the sum of direct greenhouse gas emissions (Scope 1), which are the greenhouse gas emissions emitted by the facility, and energy-related greenhouse gas emissions (Scope 2), which are calculated from the amount of electricity, gas, fuel, and heat used at the facility (hereinafter referred to as "electricity consumption, etc.").
[0031] The greenhouse gas emission reduction information input to the supply-side terminal 10 includes at least the amount of greenhouse gases emitted in the sewage treatment facility and the amount of electricity and other consumption. The energy-origin greenhouse gas emissions can be calculated by the information processing means 30 using the input amount of electricity and other consumption.
[0032] Energy-related greenhouse gas emissions can be calculated by multiplying the amount of electricity used at a sewage treatment facility by the emission intensity (emission coefficient). This calculation method is publicly known, and highly accurate calculation methods have been proposed, so an appropriate calculation method can be selected. For example, energy-related greenhouse gas emissions can be calculated using commercially available greenhouse gas emissions calculation software or estimation methods used by financial institutions. However, because the greenhouse gas emission reduction amount is the difference between the greenhouse gas emissions after the implementation of greenhouse gas emission reduction measures and the greenhouse gas emissions before the implementation or in the base year, the energy-related greenhouse gas emissions to be compared must be calculated using the same calculation method. If the same calculation method cannot be used, energy-related greenhouse gas emissions before and after the implementation of greenhouse gas emission reduction measures must be converted so that they can be compared.
[0033] The greenhouse gases emitted at wastewater treatment plants are mainly carbon dioxide, methane, and nitrous oxide. The following emission factors are used to calculate energy-related greenhouse gas emissions: Carbon dioxide: 1 Methane: 28 Nitrous oxide: 265
[0034] This section explains how to calculate the actual reductions in greenhouse gas emissions from energy sources. (1) Calculation based on the current or past base year electricity consumption at sewage treatment facilities The actual reduction in greenhouse gas emissions can be calculated by multiplying the actual reduction in electricity consumption by the greenhouse gas emission coefficient for electricity. For example, if the greenhouse gas is CO2, the emission coefficient is the CO2 emission coefficient of the power distribution company that transmits electricity to the sewage treatment facility. For example, the CO2 emission coefficient (preliminary value) for Tokyo Electric Power Company Energy Partner, Inc. for fiscal year 2022 is 0.376 kg-CO2 / kWh.
[0035] (2) Calculation based on the current or past base year gas and fossil fuel consumption at sewage treatment facilities The actual reduction in greenhouse gas emissions can be calculated by multiplying the reduction in gas and fossil fuel consumption by the greenhouse gas emission coefficient of the gas or fossil fuel. For example, the CO2 emission coefficient for city gas is 2.65 kg-CO2 / m 3 If the fossil fuel is heavy oil A, the CO2 emission coefficient is 2627 kg-CO2 / kL.
[0036] (3) Calculation based on the current or past base year water consumption at the sewage treatment facility The actual reduction in greenhouse gas emissions is calculated by comparing the reduction in tap water consumption and the number of sewage treatment facilities in the area where the facility is located, as published by the waterworks bureau. 3 For example, the greenhouse gas emissions per 1 m3 of tap water from the Tokyo Metropolitan Government's Waterworks Bureau in fiscal 2020 can be calculated by multiplying the amount of greenhouse gas emissions per 1 m3. 3 The CO2 emissions per serving is 245g.
[0037] (4) Calculation based on the current or past base year raw material usage at the sewage treatment facility. The actual greenhouse gas emission reduction amount can be calculated by multiplying the amount of raw materials used at a sewage treatment facility by the greenhouse gas emission coefficient for each raw material published by the Ministry of the Environment. For example, the greenhouse gas emission coefficient for each raw material is listed in the emission intensity in the Ministry of the Environment's "Towards Calculating and Reducing Supply Chain Emissions" (Supply Chain Emissions Detailed Information (released March 16, 2023)). In addition, in utilizing LCA to reduce the environmental impact of sewage facilities, the LCA intensity is shown for civil engineering materials and electrical facility-related materials used during construction, and for chemicals used during operation (pages 44, 47, and 121, respectively).
[0038] The projected greenhouse gas emission reductions are the sum of (1) the direct greenhouse gas emission reductions, calculated by the difference between the greenhouse gas emissions from sewage treatment facilities in the current or past base year and the greenhouse gas emissions from sewage treatment facilities after future greenhouse gas emission reduction measures are implemented, and (2) the energy-related greenhouse gas emission reductions, calculated by multiplying the difference between the electricity and other consumption in the current or past base year and the electricity and other consumption after future energy conservation measures are implemented or the electricity and other consumption derived from renewable energy after renewable energy is introduced, by an emission coefficient.
[0039] The actual and predicted greenhouse gas emission reductions will be explained using Figures 3 and 4. Figure 3 shows the case where further measures are taken after greenhouse gas emission reduction measures have been implemented, while Figure 4 shows the case where no further measures are taken after greenhouse gas emission reduction measures have been implemented.
[0040] As shown in Figures 3(a) and 4(a), the actual greenhouse gas emission reduction amount C is calculated by subtracting the actual greenhouse gas emission amount B after the implementation of the greenhouse gas emission reduction measures from the actual greenhouse gas emission amount A for the base year before the implementation of the greenhouse gas emission reduction measures. C=A-B
[0041] As shown in Figures 3(b) and 4(b), the predicted greenhouse gas emission reduction amount F is calculated by subtracting the predicted greenhouse gas emission amount E after the implementation of greenhouse gas emission reduction measures from the predicted greenhouse gas emission amount D for the base year before the implementation of greenhouse gas emission reduction measures. F=DE
[0042] The sum of the actual and predicted greenhouse gas emission reduction amounts stored in the information storage unit 32 of the information processing means 30 is AE. Here, if greenhouse gas emission reduction measures are implemented and an actual greenhouse gas emission reduction amount B is achieved, and then no further reduction measures are taken (FIG. 4), then actual value B is equal to predicted value D, and so the sum of the actual and predicted greenhouse gas emission reduction amounts is AE=(C+B)-(DF)=C+F.
[0043] Greenhouse gas emission reductions can be predicted for any period, such as fiscal year, yearly, monthly, or semi-annually. Greenhouse gas emissions from sewage treatment facilities can be predicted based on past operating records, including seasonal and treatment volume fluctuations, and no significant fluctuations will occur unless the facilities are significantly renovated, remodeled, or updated.
[0044] Greenhouse gas emissions can be reduced by updating water treatment facilities, sludge treatment facilities, or deodorization equipment to energy-saving types, or by adopting energy-saving operating methods for these facilities. Table 1 below shows some representative measures for reducing greenhouse gas emissions.
[0045] [Table 1]
[0046] The demand-side greenhouse gas emission reduction requirement information stored in the information storage unit 32 of the information processing means 30 can include, in addition to the greenhouse gas emission reduction requirement, traceability information such as the timing or period for which the greenhouse gas emission reduction amount will be supplied, and the locations and facilities where greenhouse gas emission reduction is required.
[0047] The information processing means 30 calculates actual and predicted values of greenhouse gas emission reduction amounts on the supply side 10 based on the direct greenhouse gas emission reduction amounts and electricity and other consumption amounts provided by the supply side 10, and calculates actual and predicted values of required greenhouse gas emission reduction amounts on the demand side 20 based on the required greenhouse gas emission reduction amount and required period provided by the demand side 20. The predictions can also be made using AI.
[0048] The matching / identification processing unit 34 of the information processing means 30 matches the supply-side greenhouse gas reduction amount information with the demand-side greenhouse gas requirement amount information stored in the information storage unit 32, calculates the supply-demand balance, and identifies a combination of one or more supply sides and one or more demand sides that satisfies the supply-demand balance. The combination of supply sides and demand sides is not limited to 1:1, and may be 1:many, many:1, or many:many.
[0049] The matching result issuing unit 36 of the information processing means 30 issues a matching identification result to the supply side and the demand side of the combination identified by the matching identification processing unit 34. The matching identification result is transmitted to the demand side terminal 20 and the supply side terminal 10 via electronic information transmission means 46, 48, respectively.
[0050] Figure 5 shows the flow of greenhouse gas emission reduction amount information and greenhouse gas emission reduction requirement information, taking as an example a case where the supply-side terminal 10 is a sewage treatment facility that has implemented a greenhouse gas emission reduction and the information processing means 30 is installed in a supply and demand adjustment center.
[0051] The demand side 20 includes sewage treatment facilities, companies, businesses, local governments, etc., where it is difficult to reduce greenhouse gas emissions. Examples include sewage treatment facilities, sludge recycling centers, water treatment facilities, municipal waste incineration plants, public transportation, and public facilities managed and operated by local governments.
[0052] The supply and demand sides may be facilities managed by the same local government, or by different local governments. The supply and demand adjustment center may be the management department of a sewage treatment facility on the supply or demand side, the management department of a sewage business in the local government that manages a sewage treatment facility on the supply or demand side, or a private business that conducts emissions trading.
[0053] If the supply and demand adjustment center is a private business operator that trades emissions credits, the supply and demand adjustment center may be in cooperation with a financial institution. If the supply and demand adjustment center trades emissions credits, the greenhouse gas emission reduction amount information and the greenhouse gas emission reduction requirement information may also include trading information such as the price of the emission credits and the payment method.
[0054] Figure 6 shows an example of the application of the supply and demand adjustment of greenhouse gas emission reduction amounts of the present invention to the trading of greenhouse gas emission reduction amounts. By adjusting the supply and demand of greenhouse gas emission reduction amounts of the present invention, matching between emission credit sellers (supply side) and emission credit buyers (demand side) is easily performed, and the information necessary for emission credit trading is provided.
