在非化石電源係不僅可再生能源,亦包含例如原子力。由非化石電源被發電出的電氣係包含以下二者。 1.電氣本身所具有的價值(kWh價值等) 2.作為非化石的價值 在本實施形態中,將上述2個價值之中「作為非化石的價值」稱為非化石價值。在電爐EF中,係使用以非化石價值予以定義的電力。在此的非化石價值係日本的「能源供給構造高度化法」上的非化石電源比率算定時作為非化石電源所被列入的價值。非化石價值係為了達成所設定的目標值,被新穎的電力零售事業者所購入的價值。 Non-fossil power sources include not only renewable energy, but also atomic power, for example. The electrical system generated by non-fossil power sources includes the following two types. 1. The value of the electricity itself (kWh value, etc.) 2. Value as non-fossil In this embodiment, among the above two values, "the value as a non-fossil" is called a non-fossil value. In the electric furnace EF, electricity defined by non-fossil value is used. The non-fossil value here is the value included as a non-fossil power source when calculating the ratio of non-fossil power sources in Japan's "Energy Supply Structural Advancement Law". The non-fossil value is the value purchased by a modern electricity retail business in order to achieve the set target value.

藉由非化石價值所定義的電力係可利用例如以下3個手段之中至少1個來取得及證明。 (1)非化石證書 (2)綠色電力證書 (3)J-Credit The electricity system defined by non-fossil value can be obtained and proven by at least one of the following three methods. (1) Non-fossil certificate (2)Green power certificate (3)J-Credit

非化石證書係指將以可再生能源被發電出的電氣的環境價值形成為證書的形式者。Non-fossil certificates are those that take the form of a certificate based on the environmental value of electricity generated by renewable energy.

綠色電力證書係指以可再生能源被發電出的電力的環境價值的證書。在綠色電力證書係標註序號,因此獨一無二。在綠色電力證書係包含發電電力量、發電期間、發電方法、與證書發行日的資訊。在綠色電力證書係另外包含認證機構名、與證書發行事業者名的資訊。Green power certificates refer to certificates of the environmental value of electricity generated with renewable energy. The green power certificate is marked with a serial number, making it unique. The green power certificate contains information on the amount of electricity generated, the period of power generation, the method of power generation, and the certificate issuance date. The green power certificate system also contains information on the name of the certification body and the name of the certificate issuing entity.

J-Credit係指將二氧化碳等溫室效應氣體的排出削減量與吸收量形成為「信用額度(credit)」而由國家所認證的制度。J-Credit is a system that converts emission reductions and absorptions of greenhouse gases such as carbon dioxide into "credits" and is certified by the country.

作為替代例,在電爐EF所使用的電力可為以零排放價值予以定義的電力,而非以非化石價值予以定義的電力。在此的零排放價值係指日本的「地球暖化對策推進相關法律」(以下為溫對法)上的二氧化碳排出係數為零的價值。具體而言,零排放價值係在電氣零售事業者在算定調整後排出係數時,可將對所籌備的非化石證書的電力量乘以「全國平均係數」所算出的二氧化碳排出量,由實際二氧化碳排出量進行減算的價值。製造業等電力購入者根據溫對法而對國家報告二氧化碳排出量時,具零排放價值的電力的二氧化碳排出係數成為零。例如,以零排放價值予以定義的電力可為既有的電力銷售公司以水力等可再生能源或原子力所發電的電力。以零排放價值予以定義的電力係可藉由以下手段來取得及證明。 (5)與電力零售的契約(例:被東京電力Energy Partner(註冊商標)公司所提供的「AQUA PREMIUM」(註冊商標)及「AQUA ENERGY 100」) As an alternative, the electricity used in the electric furnace EF may be electricity defined in terms of a zero-emission value, rather than electricity defined in terms of a non-fossil value. The zero-emission value here refers to the value where the carbon dioxide emission coefficient is zero according to Japan's "Law on the Promotion of Global Warming Countermeasures" (hereinafter referred to as the Temperature Control Law). Specifically, the zero-emission value is calculated by multiplying the electricity amount of the non-fossil certificate prepared by the "national average coefficient" when the electrical retail business calculates the adjusted emission coefficient. The discharge amount is subtracted from the value. When power purchasers such as the manufacturing industry report their carbon dioxide emissions to the country based on the Temperature Compensation Act, the carbon dioxide emission coefficient of electricity with zero-emission value becomes zero. For example, electricity defined by zero-emission value can be electricity generated by existing electricity sales companies using renewable energy sources such as hydropower or atomic power. Electricity systems defined by zero-emission values can be obtained and certified through the following means. (5) Contract with electricity retail (for example: "AQUA PREMIUM" (registered trademark) and "AQUA ENERGY 100" provided by Tokyo Electric Power Energy Partner (registered trademark))

Obtained by business operators or certification agencies. The above means (1) to (5) are examples, and can be replaced by any other means that proves that the electricity used in the electric furnace EF is electricity defined by non-fossil value or zero-emission value.

在本發明中,在電爐EF所使用的電力為以非化石價值或零排放價值予以定義的電力的證明方法係有:藉由上述(1)至(5)之任一者,取得證明資訊來進行證明的方法、或若無法取得證明資訊,則利用藉由電力公司等所被公開的任意證明資訊(例如二氧化碳排出係數(殘渣))而僅特定由可再生能源而來的電力的方法(詳容後述)。In the present invention, the method for proving that the electric power used in the electric furnace EF is electric power defined by non-fossil value or zero-emission value is to obtain certification information through any one of the above (1) to (5).

Integration of certification information for defined electric power. Here, certification information means that it can be obtained through the following methods. In order to realize that the electric power used in the electric furnace EF is electric power defined in terms of non-fossil value or zero-emission value, first, the electric furnace EF is used to manufacture the steel product with the manufacturing batch number recorded in the test certificate of the subject steel. Calculate the power usage per ton of steel based on the actual power usage of the factory per unit of heat energy. The calculation can be performed by the control unit 11 (for example, a process computer) or manually (the same applies below). 1Thermal energy refers to the molten steel that is melted once in the electric furnace EF. From the melted molten steel, steel products are manufactured in batches. Next, the amount of electricity used per ton of steel is multiplied by the weight of the product stated in the test certificate of the subject steel product to calculate the actual power usage used to manufacture the subject steel product. By converting the actual amount of electricity used into non-fossil electricity, it is possible to realize and prove that the electricity used in the electric furnace EF is electricity defined by non-fossil value or zero-emission value.

以將鋼材試驗證書資訊與證明資訊一體化的方法的具體而言,控制部11係如圖7的製造批次DB所示,與製造批次L1建立關連而將區塊鏈BC的區塊B1、鋼材試驗證書資訊M1與證明資訊V1記憶在記憶部13。亦即,鋼材試驗證書資訊M1與證明資訊V1係作為交易資料而被登錄在區塊鏈BC的區塊B1內。所被登錄的資訊係被記憶作為區塊鏈BC的代幣(token)。以替代例而言,證明資訊V1亦可被埋入在鋼材試驗證書資訊M1。Specifically, in the method of integrating steel test certificate information and certification information, the control unit 11 establishes a relationship with the manufacturing batch L1 as shown in the manufacturing batch DB in FIG. 7 and links the block B1 of the blockchain BC , the steel test certificate information M1 and the certification information V1 are stored in the memory unit 13 . That is, the steel test certificate information M1 and certification information V1 are registered in block B1 of the blockchain BC as transaction data. The registered information is stored as the token of the blockchain BC. As an alternative example, the certification information V1 can also be embedded in the steel test certificate information M1.

控制部11係可以任意第三者為對象,在網際網路等公開鋼材試驗證書資訊M1及證明資訊V1。The control unit 11 can disclose the steel material test certificate information M1 and certification information V1 to any third party on the Internet or the like.

參照圖8,說明藉由資訊處理裝置1的控制部11所進行之資訊處理方法。Referring to FIG. 8 , the information processing method performed by the control unit 11 of the information processing device 1 will be described.

在步驟S1中,控制部11係取得:關於鋼材製品的製造批次的鋼材試驗證書資訊;及證明製造批次的製造所使用的電力為以非化石價值或零排放價值予以定義的電力的證明資訊。In step S1, the control unit 11 obtains: steel material test certificate information on the manufacturing batch of the steel product; and proof that the electricity used in the manufacturing of the manufacturing batch is electricity defined in terms of non-fossil value or zero-emission value. information.

在步驟S2中,控制部11係藉由將鋼材試驗證書資訊與證明資訊建立關連而一體化。In step S2, the control unit 11 integrates the steel material test certificate information and the certification information by establishing a relationship.

在步驟S3中,控制部11係將建立關連的鋼材試驗證書資訊與證明資訊登錄在網路NW(例如區塊鏈網路NW)。步驟S3為任意。In step S3, the control unit 11 registers the associated steel material test certificate information and certification information in the network NW (for example, the blockchain network NW). Step S3 is optional.

在步驟S4中,控制部11係在網際網路公開建立關連的鋼材試驗證書資訊與證明資訊。步驟S4為任意。In step S4, the control unit 11 publishes the related steel material test certificate information and certification information on the Internet. Step S4 is optional.

[變形例] 在上述實施形態中,鋼材試驗證書資訊與證明資訊建立關連被記憶在記憶部13。但是,有控制部11無法取得綠色電力證書等證明資訊的情形。因此,控制部11係若被電力需要者所購入的電力的發電過程為複合式利用了可再生能源與可再生能源以外的能源的過程時,可僅特定所被購入及使用的電力之中由可再生能源而來的電力。如上所示之特定係可利用被電力公司等所公開的任意證明資訊(例如二氧化碳排出係數(殘渣))來進行。控制部11可將證明資訊,與鋼材試驗證書資訊建立關連來進行記憶。 [Modification] In the above embodiment, the steel material test certificate information and the certification information are associated and stored in the memory unit 13 . However, the control unit 11 may not be able to obtain certification information such as a green power certificate. Therefore, if the power generation process of the electric power purchased by the electric power demander is a process that compositely utilizes renewable energy and energy other than renewable energy, the control unit 11 can only specify the source of the electric power purchased and used. Electricity from renewable sources. The above-mentioned specification can be performed using any certification information (such as carbon dioxide emission coefficient (residue)) disclosed by electric power companies and the like. The control unit 11 can associate the certification information with the steel material test certificate information and store it.

如上所述,若被電力需要者所購入的電力的發電過程為複合式利用了可再生能源與可再生能源以外的能源的過程,可僅特定所被購入及使用的電力之中由可再生能源而來的電力。可特定的理由係基於在「日本經濟產業省第15次綜合資源能源調查會電力/天然氣事業分科會 電力/天然氣基本政策小委員會制度檢討作業部會(2017年11月28日)」中被設定為如下所示之故。亦即,若假定FIT(Feed-in Tariff:固定價格躉購制度)對象的非化石證書的競標(auction)的結果,發生未被約定而賣剩的非化石證書時,該非化石證書並無法被轉至下年度之後,形成為「剩餘非化石電氣相當量」,惟有關剩餘非化石電氣相當量的環境價值之中針對零排放價值,鑑於用戶負擔費用作為FIT賦稅款等,不會有使價值埋没的情形,按照銷售電力量的占有率來作分配。As mentioned above, if the power generation process of the power purchased by the power demander is a process that uses renewable energy and energy other than renewable energy in a composite manner, only the renewable energy source in the purchased and used power can be specified. coming electricity. The reason for specifying is based on the "15th Comprehensive Resources and Energy Survey of Japan's Ministry of Economy, Trade and Industry, Electricity/Gas Business Subcommittee Electricity/Gas Basic Policy Subcommittee System Review Operation Committee (November 28, 2017)" The reason is as follows. That is, if, as a result of the auction of non-fossil certificates subject to FIT (Feed-in Tariff: fixed-price wholesale purchase system), non-fossil certificates are sold without being agreed upon, the non-fossil certificates cannot be sold. After the transfer to the next fiscal year, it will be regarded as "residual non-fossil electricity equivalent". However, the environmental value of the remaining non-fossil electricity equivalent is zero-emission value. Since users pay fees as FIT taxes, etc., there will be no usable value. In the case of burying, allocation will be made according to the share of the power sold.

此外,本年度的電力公司的二氧化碳排出係數係有在年度結束後被公開的情形。此時,本年度的二氧化碳排出係數係可藉由控制部11依以下順序算出。 順序1.由前年度的二氧化碳排出係數與非化石電力比率,推定前年度基礎下的非化石電力的可使用量,且對本年度在工廠使用的預定電力計畫反映推定結果。以替代例而言,在非化石電力比率可採用被任意自治團體所公開的能源環境計畫書所記載的本年度可再生能源比率目標值。 順序2.按照來自顧客的要求,撥出本年度的非化石電力。 順序3.在本年度的二氧化碳排出係數已被公開的時點,調整及確定非化石電力的撥出份、與非化石電力以外的剩餘的電力的撥出份的實績。 In addition, the carbon dioxide emission coefficient of electric power companies for the current year may be disclosed after the end of the year. At this time, the carbon dioxide emission coefficient for this year can be calculated by the control unit 11 according to the following procedure. Procedure 1. Based on the carbon dioxide emission coefficient and the non-fossil electricity ratio of the previous year, estimate the usable amount of non-fossil electricity based on the previous year, and reflect the estimation results on the power plan scheduled to be used at the factory this year. As an alternative example, the non-fossil electricity ratio may be the current year's renewable energy ratio target value recorded in an energy environment plan published by any local government. Sequence 2. Allocate non-fossil electricity for the current year in accordance with requests from customers. Procedure 3. When the carbon dioxide emission coefficient for the current year is disclosed, adjust and determine the actual performance of the allocation of non-fossil electricity and the allocation of remaining electricity other than non-fossil electricity.

若發電過程為複合式利用了可再生能源與可再生能源以外的能源的過程,僅特定所被購入及使用的電力之中由可再生能源而來的電力的方法係可由以下方法取得。為了實現在電爐EF所使用的電力為以非化石價值或零排放價值予以定義的電力,首先,由相當於製造出成為對象的鋼材試驗證書所記載的製造批次號的鋼材製品的電爐EF的1熱能份的工廠電力使用量實績,算出每噸鋼的電力使用量。算出係可藉由控制部11(例如製程電腦)進行,亦可以手動進行(以下同)。1熱能係指在電爐EF中1次熔解的熔鋼。由經熔解的熔鋼,依批次別製造鋼材製品。接著,對1次熔解的熔鋼量,乘上藉由電力公司等被公開的可再生能源比率,藉此算出從由可再生能源而來的電力所製造出的熔鋼量。控制部11係對使用從由可再生能源而來的電力所製造出的熔鋼所製造的鋼材製品的鋼材試驗證書,將所使用之由可再生能源而來的電力量建立關連而一體化。If the power generation process is a process that combines renewable energy and energy sources other than renewable energy, the following method can be used to identify only the electricity generated from renewable energy among the purchased and used electricity. In order to realize that the electric power used in the electric furnace EF is electric power defined in terms of non-fossil value or zero-emission value, first, the electric furnace EF is used to manufacture the steel product with the manufacturing batch number recorded in the test certificate of the subject steel. Calculate the power usage per ton of steel based on the actual power usage of the factory per unit of heat energy. The calculation can be performed by the control unit 11 (for example, a process computer) or manually (the same applies below). 1Thermal energy refers to the molten steel that is melted once in the electric furnace EF. From the melted molten steel, steel products are manufactured in batches. Next, the amount of molten steel produced in one melting is multiplied by the renewable energy ratio disclosed by electric power companies, etc., to calculate the amount of molten steel produced from electricity generated from renewable energy. The control unit 11 correlates and integrates the steel material test certificates of steel products produced using molten steel produced from electricity derived from renewable energy, and the amount of electricity used from renewable energy.

[效果] 如以上所述,藉由本實施形態,鋼材製品係在使用了以非化石價值或零排放價值予以定義的電力的電爐中所製造。在此,在電爐所製造的鋼材製品係由僅有鋼的單一素材所構成,主原料為廢鐵。此外,在電爐所使用的能源的大部分(例如80%以上)為電力。基於該等情形,藉由籌備以非化石價值或零排放價值予以定義的電力(例如綠色電力)而在電爐使用,可將由在製造工程中所使用的焦炭等被排出的二氧化碳相抵。亦即,相抵係指算出相當於焦炭等能源的非化石電力使用量,將所被算出的非化石電力使用量追加記載在鋼材試驗證書,且作為在鋼材製品的製造中所使用的非化石電力而與鋼材製品建立關連來進行。因此,可製造碳中和的鋼材製品。此外,即使為小批次,亦容易證明鋼材製品為碳中和。因此,可進行銷售價格上升等PR(宣傳、理解促進)活動。 [Effect] As described above, according to this embodiment, steel products are produced in an electric furnace using electricity defined in terms of non-fossil value or zero-emission value. Here, the steel products manufactured in the electric furnace are composed of a single material of only steel, and the main raw material is scrap iron. In addition, most (for example, more than 80%) of the energy used in electric furnaces is electricity. Based on these circumstances, by preparing electricity defined by non-fossil value or zero-emission value (such as green electricity) for use in electric furnaces, the carbon dioxide emitted from coke, etc. used in the manufacturing process can be offset. That is, offsetting means to calculate the non-fossil electricity usage equivalent to energy such as coke, add the calculated non-fossil electricity usage to the steel test certificate, and treat it as non-fossil electricity used in the manufacture of steel products. And to establish a relationship with steel products. As a result, carbon-neutral steel products can be produced. In addition, it is easy to prove that steel products are carbon neutral, even for small batches. Therefore, PR (publicity and understanding promotion) activities such as increasing sales prices can be carried out.

在對照上,製造汽車等時,係使用由各種原料而來的各種零件。此外,製造時所使用的能源為電力、天然氣、及石油等多種。此時,為了證明製品為碳中和,必須針對各個零件全部證明為碳中和。因此,證明非常複雜且困難。為了實現碳中和,可利用根據LCA評估的環保標章等,但是由於進行定性上的評估,因此影響力較弱。此外,該評估僅為全體性評估。因此,若為自動車等的製造,難以製造碳中和製品的可能性高。In contrast, when manufacturing automobiles, various parts made from various raw materials are used. In addition, the energy used in manufacturing includes electricity, natural gas, and oil. At this time, in order to prove that the product is carbon neutral, each part must be certified as carbon neutral. Therefore, the proof is very complex and difficult. In order to achieve carbon neutrality, environmental labels based on LCA evaluation can be used, but since the evaluation is qualitative, the impact is weak. Furthermore, this evaluation is a comprehensive evaluation only. Therefore, in the manufacturing of automobiles and the like, there is a high possibility that it will be difficult to produce carbon-neutral products.

此外,藉由本實施形態,資訊處理裝置1係將關於鋼材製品的製造批次的鋼材試驗證書資訊、與證明製造批次的製造所使用的電力為以非化石價值或零排放價值予以定義的電力的證明資訊建立關連。藉由該構成,形成為關於製造批次的鋼材試驗證書資訊、與證明前述製造批次的製造所使用的電力為以非化石價值或零排放價值予以定義的電力的證明資訊建立關連的鋼材製品,且容易證明所製造出的鋼材製品為碳中和。In addition, according to this embodiment, the information processing device 1 combines the steel material test certificate information regarding the manufacturing batch of the steel product and the electricity used to prove that the manufacturing batch is defined as a non-fossil value or a zero-emission value. Establish a relationship with the certification information. This configuration creates a steel product that is linked to the steel product test certificate information on the production batch and the certification information proving that the electricity used in the production of the production batch is electricity defined in terms of non-fossil value or zero-emission value. , and it is easy to prove that the steel products produced are carbon neutral.

此外,藉由本實施形態,網路NW係包含區塊鏈網路,已建立關連的鋼材試驗證書資訊與證明資訊係被登錄在區塊鏈。若如上所示利用區塊鏈技術,登錄資訊分散在全部節點共有。亦即不需要中央管理者。因此,達成以下效果。 ・不易篡改 ・由於無單一障礙點,因此無系統故障 ・與他者系統的資料共有容易 因此,資訊處理裝置1係可實現安全性高且低成本的系統。此外,由於在區塊鏈記錄全部資料,因此確保可追溯性(traceability)。 In addition, according to this embodiment, the network NW includes a blockchain network, and the related steel material test certificate information and certification information are registered in the blockchain. If blockchain technology is used as shown above, the login information is dispersed and shared by all nodes. That is, there is no need for a central manager. Therefore, the following effects are achieved. ・Not easy to tamper with ・Since there is no single point of failure, there are no system failures ・Easy to share data with other systems Therefore, the information processing device 1 can realize a highly secure and low-cost system. In addition, since all data is recorded on the blockchain, traceability is ensured.

此外,藉由本實施形態,控制部11係在網際網路公開已建立關連的鋼材試驗證書資訊與證明資訊。藉由該構成,資訊處理裝置1係可對外地表示鋼材製品為碳中和。In addition, according to this embodiment, the control unit 11 discloses the related steel material test certificate information and certification information on the Internet. With this configuration, the information processing device 1 can externally indicate that the steel product is carbon neutral.

此外,藉由本實施形態,控制部11係若所被購入的電力的發電過程為複合式利用了可再生能源與可再生能源以外的能源的過程時,將特定電力之中由可再生能源而來的電力、及證明所被特定出的電力為由可再生能源而來的電力的證明資訊,與關於鋼材製品的製造批次的鋼材試驗證書資訊建立關連。藉由該構成,資訊處理裝置1即使在發電過程中使用了可再生能源以外的能源,亦可證明鋼材製品部分為碳中和。In addition, according to this embodiment, when the power generation process of the purchased electric power is a process in which renewable energy and energy sources other than renewable energy are used in a composite manner, the specific electric power is generated from the renewable energy. The electric power and the certification information proving that the specified electric power is generated from renewable energy are related to the steel test certificate information on the manufacturing batch of the steel product. With this configuration, even if the information processing device 1 uses energy other than renewable energy in the power generation process, it can be proven that the steel product part is carbon neutral.

Computer-readable recording media include non-transitory computer-readable media, such as magnetic recording devices, optical discs, magneto-optical recording media, or semiconductor memories. The distribution of programs is, for example, through the sale, transfer, or transfer of portable recording media such as DVDs (Digital Versatile Discs) or CDROMs (Compact Disc Read Only Memory) on which programs are recorded.

Then, the computer uses the processor to read the program stored in the main memory device, and the processor executes processing according to the read program. The computer can also directly read the program from the portable recording medium and perform processing according to the program. The computer can also execute the processing according to the received program each time the server transfers the program to the computer. It is also possible to realize the function only by executing instructions and obtaining results without transferring the program from the server to the computer, and the processing can be performed by a so-called ASP type service. "ASP" is the abbreviation of application service provider. A program contains information for processing by an electronic computer and is in accordance with the program. For example, although it is not a direct instruction to a computer, data of a nature that requires computer processing is equivalent to "according to a program."
