[0018] The present invention will be described below through embodiments of the invention, but the following embodiments do not limit the scope of the invention. Furthermore, not all of the combinations of features described in the embodiments are necessarily essential to the solution of the invention. First, a method for displaying carbon energy and carbon energy ratio according to one embodiment of the present invention will be described.

[0019] <<How to display carbon energy and carbon energy ratio>> 1 is a flowchart illustrating a method for displaying carbon energy and a carbon energy ratio according to an embodiment of the present invention. As shown in FIG. 1, the method for displaying carbon energy and a carbon energy ratio according to an embodiment of the present invention has the following features.

[0020] The method is characterized by comprising the steps of: calculating the carbon energy ratio using the carbon calorific value, the carbon mass in the fuel, the hydrogen calorific value, and the hydrogen mass in the fuel and formula (1); calculating the carbon energy by multiplying the carbon energy ratio by the calorific value of the fuel; and displaying the energy and carbon energy on a single display medium according to the magnitude of the energy and the magnitude of the carbon energy. Carbon energy ratio = (carbon calorific value * mass of carbon in fuel) / (carbon calorific value * mass of carbon in fuel + hydrogen calorific value * mass of hydrogen in fuel) Equation (1).

[0021] <Step of calculating the carbon energy ratio using the carbon calorific value, the carbon mass in the fuel, the hydrogen calorific value, the hydrogen mass in the fuel, and formula (1)> The carbon-to-energy ratio is calculated using the carbon calorific value, the mass of carbon in the fuel, the hydrogen calorific value, and the mass of hydrogen in the fuel, using equation (1). Fuel refers to fuel that is a primary energy source. Examples of fuel include fossil fuels and hydrocarbon fuels. Examples of fossil fuels include coal, oil, and natural gas. The mass of carbon in a fuel is the total mass of carbon contained in the fuel. The carbon calorific value is the amount of heat generated when all carbon per unit mass is burned and converted to carbon dioxide. The hydrogen mass in a fuel is the total mass of hydrogen per unit mass. The hydrogen calorific value is the amount of heat generated when all hydrogen contained in a fuel is burned and converted to water.

[0022] If the fuel contains carbon with two or more different bonding states, the carbon calorific value may be calculated by multiplying the mass of carbon in each bonding state by the calorific value when carbon in each bonding state is burned to form carbon dioxide, and then summing these values. A known value may be used for the calorific value when carbon in each bonding state is burned to form carbon dioxide. A known value may be used for the amount of heat generated when all hydrogen contained in the fuel is burned to form water.

[0023] The fuel may be a fuel used in any system, such as a company, a city, a prefecture, a nation, or the entire world.

[0024] The fuel may contain trace elements such as sulfur and nitrogen. The carbon-to-energy ratio may be calculated taking into account trace elements such as sulfur and nitrogen. In this case, the carbon-to-energy ratio may be calculated using the carbon calorific value, the carbon mass in the fuel, the hydrogen calorific value, the hydrogen mass in the fuel, the sulfur calorific value, and the sulfur mass in the fuel, using Equation (2). Carbon energy ratio = (carbon calorific value * mass of carbon in fuel) / (carbon calorific value * mass of carbon in fuel + hydrogen calorific value * mass of hydrogen in fuel + sulfur calorific value * mass of sulfur in fuel) Equation (2).

[0025] The sulfur calorific value is the amount of heat generated when sulfur per unit mass is burned and all of it becomes sulfur dioxide. The nitrogen calorific value is the amount of heat generated when nitrogen per unit mass is burned and all of it becomes nitrogen dioxide. Known values ​​for the sulfur calorific value and nitrogen calorific value can be used.

[0026] The carbon dioxide energy can be calculated more accurately if trace elements such as sulfur and nitrogen are taken into account when calculating the carbon energy ratio. Note that trace elements such as sulfur and nitrogen include not only elements chemically bonded to hydrocarbons in the fuel, but also elements that exist as simple elements.

[0027] <Process of calculating carbon energy by multiplying the carbon energy ratio by the calorific value of the fuel> In the step of calculating carbon energy by multiplying the carbon energy ratio by the calorific value of the fuel, the carbon energy calculated above is multiplied by the calorific value of the fuel to calculate carbon energy. The calorific value of the fuel refers to the calorific value when the fuel is completely combusted. When the fuel is a hydrocarbon fuel, the calorific value of the fuel may be the sum of the calorific values ​​of the carbon and hydrogen in the hydrocarbon fuel when all of them become carbon dioxide and water. When the fuel is a fossil fuel containing elements other than carbon and hydrogen, the calorific value may be the sum of the calorific values ​​of the carbon and hydrogen in the hydrocarbon fuel when all of them become carbon dioxide and water, plus the calorific value when the elements other than carbon and hydrogen are combusted.

[0028] Energy and carbon energy are displayed on a single display medium according to the amount of energy and the amount of carbon energy calculated above. The amount of energy refers to the amount of primary energy used in the same system as the aforementioned fuel. Primary energy includes renewable energy, fossil fuel energy, and nuclear energy. Renewable energy includes solar, wind, hydropower, heat found in nature, biomass, and ocean energy.

[0029] Depending on the magnitude of energy and the magnitude of carbon energy calculated above, the energy and carbon energy may be displayed on the same display medium while maintaining the ratio between the magnitude of energy and the magnitude of carbon energy, or the magnitude of energy and the magnitude of carbon energy may be converted to other quantities and displayed on the same display medium. Energy and carbon energy may also be displayed graphically. For example, if the figure is a line, it may be represented by the length of the line; if the figure is two-dimensional, it may be represented by the area of ​​the figure; and if the figure is three-dimensional, it may be represented by the volume of the figure.

[0030] The magnitude of energy may be represented by a single figure, and the magnitude of carbon energy may be represented in a form that allows a portion of the figure to be visually distinguished from the other portions. For example, the magnitude of energy may be represented by a straight line, and a portion of the line may be colored differently so that the ratio of the length of the entire straight line to the length of the colored portion is the same as the ratio of the magnitude of energy to the magnitude of carbon energy.

[0031] The display method may be to display it in the form of an attachment to an object, or to display it as an image using an electromagnetic method. The carbon energy may be calculated over time, and the energy and carbon energy may be displayed in chronological order.

[0032] The mass ratio of carbon and hydrogen in fuel varies depending on the type of fuel. Therefore, the mass of fuel is not necessarily proportional to the mass of carbon dioxide produced when all of the fuel is burned. This makes it difficult for energy consumers to easily recognize carbon dioxide emissions from their energy consumption. As a result, energy consumers are less motivated to review their energy consumption in order to reduce carbon dioxide emissions. It is also difficult to grasp the appropriate energy consumption to reduce carbon dioxide emissions. On the other hand, according to the method for displaying carbon energy and carbon energy ratio according to this embodiment, carbon energy has a strong correlation with carbon dioxide emissions. Therefore, the amount of carbon dioxide emissions can be understood from carbon energy, which represents the amount of energy consumed. This makes it easier to determine the amount of carbon dioxide emissions.

[0033] Furthermore, carbon energy has the same dimensions as consumed energy. Therefore, carbon energy can be displayed on the same chart as other consumed energy. This allows for a more accurate determination of the proportion of energy that emits carbon dioxide in total energy. The relationship between carbon dioxide-emitting energy and other energy sources can be clearly understood, making it easier to consider policies for reducing carbon dioxide emissions.

[0034] This embodiment may further include a step of calculating the hydrogen energy in the hydrocarbon from the difference between the hydrocarbon energy and the carbon energy. The hydrogen energy may be calculated using the following formula: Hydrogen energy = Hydrocarbon energy - Carbon energy

[0035] In this embodiment, the carbon energy ratio may be calculated from the carbon dioxide emission intensity and the relationship between the carbon energy ratio and the carbon dioxide emission intensity. The relationship between the carbon energy ratio and the carbon dioxide emission intensity may be expressed by, for example, the following formula (3). Carbon energy ratio = carbon dioxide emission intensity * coefficient (3) Here, the coefficient may be an emission coefficient that indicates the rate at which various hydrocarbons are emitted. For example, as shown in Figure 3, the carbon energy ratio of various hydrocarbons may be calculated using the carbon dioxide emission intensity of each hydrocarbon and the emission coefficient that indicates the rate at which each hydrocarbon is emitted.

[0036] In this embodiment, the energy and carbon energy may be displayed directly, or information obtained based on the energy and carbon energy may be displayed.

[0037] Next, a carbon energy and carbon energy ratio display device according to another embodiment of the present invention will be described.

[0038] <Carbon energy and carbon energy ratio display device> Another embodiment of the present invention provides a carbon energy and carbon energy ratio display device, characterized by comprising: a calculation unit that calculates the carbon energy ratio using the carbon calorific value, the carbon mass in the fuel, the hydrogen calorific value, the hydrogen mass in the fuel, and equation (1), and calculates the carbon energy by multiplying the carbon energy ratio by the calorific value of the fuel; and a display unit that displays the energy and carbon energy on a single display medium according to the magnitude of the energy and the magnitude of the carbon energy.

[0039] Carbon energy ratio = (Carbon calorific value * Carbon mass in fuel) / (Carbon calorific value * Carbon mass in fuel + Hydrogen calorific value * Hydrogen mass in fuel) Equation (1)

[0040] An information provision system 100 including a display device for carbon energy and carbon energy ratio according to an embodiment of the present invention will be described. FIG. 2 is a diagram illustrating an example of the configuration of the information provision system 100 including a display device for carbon energy and carbon energy ratio according to an embodiment of the present invention. As illustrated in FIG. 2, the information provision system 100 includes a display device 200 for carbon energy and carbon energy ratio and a terminal device 300. The display device 200 for carbon energy and carbon energy ratio includes a control device 15, a calculation device 25, and a receiving device 35. The terminal device 300 is a specific example of a user terminal. The display device 200 for carbon energy and carbon energy ratio and the terminal device 300 are communicatively connected via a network 60. The network 60 may be a wireless communication network, a wired communication network, or a combination of a wireless communication network and a wired communication network. The network 60 may be a wide-area communication network, a local communication network, or a single cable. In other words, the network 60 may be configured in any manner as long as it is a communication path capable of transmitting data.

[0041] The carbon energy and carbon energy ratio display device 200 receives data on at least the carbon calorific value, the carbon mass in the fuel, the hydrogen calorific value, and the hydrogen mass in the fuel via a network, calculates the carbon energy ratio using the carbon calorific value, the carbon mass in the fuel, the hydrogen calorific value, and the hydrogen mass in the fuel and equation (1), and calculates the carbon energy by multiplying the carbon energy ratio by the calorific value of the fuel. The carbon calorific value and the hydrogen calorific value may be known values. Carbon energy ratio = (Carbon calorific value * Carbon mass in fuel) / (Carbon calorific value * Carbon mass in fuel + Hydrogen calorific value * Hydrogen mass in fuel) Equation (1)

[0042] In addition, the carbon energy and carbon energy ratio display device 200 receives data on at least the carbon calorific value, the carbon mass in the fuel, the hydrogen calorific value, the hydrogen mass in the fuel, the sulfur calorific value, the sulfur mass in the fuel, the nitrogen calorific value, and the nitrogen mass in the fuel via the network, and calculates the carbon energy ratio using the carbon calorific value, the carbon mass in the fuel, the hydrogen calorific value, the hydrogen mass in the fuel, the sulfur calorific value, and the sulfur mass in the fuel, and equation (2). Carbon energy ratio = (Carbon calorific value * Carbon mass in fuel) / (Carbon calorific value * Carbon mass in fuel + Hydrogen calorific value * Hydrogen mass in fuel + Sulfur calorific value * Sulfur mass in fuel) Equation (2)

[0043] The control device 15 is configured using an information processing device such as a programmable logic controller (PLC), a single-board computer, a personal computer, etc. The control device 15 controls the calculation device 25 to perform calculations. The control device 15 controls the reception device 35 to receive.

[0044] The calculation device 25 performs calculations using the data received by the receiving device 35. The calculation device 25 is a specific example of a calculation unit. The calculation device 25 may calculate the hydrogen energy in the hydrocarbon from the difference between the hydrocarbon energy and the carbon energy.

[0045] The receiving device 35 receives data from the terminal device 300. The received data includes, for example, the carbon calorific value, the carbon mass in the fuel, the hydrogen calorific value, the hydrogen mass in the fuel, the sulfur calorific value, the sulfur mass in the fuel, the nitrogen calorific value, and the nitrogen mass in the fuel.

[0046] The terminal device 300 is configured using an information processing device such as a personal computer, a server device, or a dedicated device. When the terminal device 300 acquires a state value or a physical quantity, it stores the acquired state value or physical quantity in a storage device in association with date and time information. The terminal device 300 transmits predetermined values ​​of the acquired state values ​​or physical quantities to the carbon energy and carbon energy ratio display device 200 via the network 60. The transmitted values ​​include, for example, the carbon calorific value, the carbon mass in the fuel, the hydrogen calorific value, the hydrogen mass in the fuel, the sulfur calorific value, the sulfur mass in the fuel, the nitrogen calorific value, and the nitrogen mass in the fuel.

[0047] The terminal device 300 may include an input device and an output device. The input device may be configured using existing input devices such as a keyboard, a pointing device (mouse, tablet, etc.), buttons, and a touch panel. The input device may be configured using a microphone and a voice recognition device. In this case, the input device performs voice recognition on words spoken by a user and inputs the character string information resulting from the recognition to the terminal device 300. The input device may be configured in any manner as long as it can input user instructions to the terminal device 300. The output device may be configured using, for example, a device that outputs images and text to a screen. For example, the output device may be configured using a CRT (Cathode Ray Tube), a liquid crystal display, an organic EL (Electro-Luminescent) display, or the like. The output device may also be configured using a device that prints images and text on a sheet. For example, the output device may be configured using an inkjet printer, a laser printer, or the like. The output device may also be configured using a device that converts text into speech and outputs it. In this case, the output device may be configured using a speech synthesizer and a voice output device (speaker). The output device may be configured using a light-emitting device such as an LED (Light Emitting Diode). In this case, the output device may cause the light-emitting device to emit light in a manner that is pre-associated with the information to be output, or may cause the light-emitting device to emit light at a position that is pre-associated with the information to be output.

[0048] The terminal device 300 acquires values ​​obtained by the user operating the input device. For example, the output device outputs values ​​input via the input device, values ​​of carbon energy and carbon energy ratio estimated by the display device 200, and the like.

[0049] This embodiment also provides a turbulent kinetic energy dissipation rate estimation program for causing a computer to function as a display device for carbon energy and carbon energy ratio, and a non-transitory computer-readable recording medium storing the program. Examples of non-transitory computer-readable recording media include magnetic tape (such as digital data storage (DSS)), magnetic disks (such as hard disk drives (HDDs) and flexible disks (FDs)), optical disks (such as compact disks (CDs), digital versatile disks (DVDs), and Blu-ray disks (BDs)), magneto-optical disks (MOs), and flash memories (such as solid-state drives (SSDs), memory cards, and USB memories).

[0050] In this embodiment, the energy and carbon energy may be displayed directly, or information obtained based on the energy and carbon energy may be displayed. [Example]

[0051] The effects of the present invention will be explained in more detail below with reference to examples. The conditions in the examples are merely examples adopted to confirm the feasibility and effects of the present invention, and the present invention is not limited to these examples. Various conditions may be adopted in the present invention as long as they do not deviate from the gist of the present invention and the object of the present invention is achieved.

[0052] First, the carbon energy of different types of energy was calculated to examine the relationship between carbon energy and carbon dioxide emissions. Using equation (1), the carbon energy was calculated for hydrogen, methane, ethane, propane, n-butane, n-pentane, crude oil, and seven types of coal produced in the United States and Australia. The calculated carbon energy for hydrogen, methane, ethane, propane, n-butane, n-pentane, crude oil, and the seven types of coal produced in the United States and Australia was plotted on the horizontal axis of a graph, and their carbon dioxide emissions on the vertical axis.

[0053] Figure 3 shows the relationship between carbon energy and carbon dioxide emissions for various energy sources. As shown in Figure 3, it was confirmed that there is a high correlation between carbon energy and carbon dioxide emissions. In other words, even if carbon energy is used instead of carbon dioxide emissions, carbon dioxide emissions can be quantitatively analyzed.

[0054] Next, we used carbon energy to analyze actual data and confirmed the versatility of carbon energy.

[0055] Figure 4 shows the changes in primary energy, the breakdown of primary energy, and carbon dioxide emissions over time. In Figure 4, CE represents carbon energy, HE represents hydrogen-related energy, Traditional RE represents classical renewable energy (bioenergy), RE represents non-classical renewable energy, and NE represents nuclear energy. Note that 2040CP, 2040NP, and 2040SD are forecast values ​​calculated using data from the International Energy Agency (IEA), World Energy Balances and Statistics, IEA, 2019. As shown in Figure 4, we confirmed that there is a strong correlation between the changes in carbon energy over time and changes in carbon dioxide emissions. Furthermore, the proportion of carbon energy in total energy can be easily confirmed. In other words, a single graph allows us to confirm both carbon dioxide emissions, carbon energy, and the carbon energy ratio. The "energy" in the proportion of carbon energy in total energy mentioned here may refer to all primary energy.

[0056] Figure 5 shows the data normalized to 100% primary energy in Figure 4. The symbols showing the breakdown of primary energy in Figure 5 have the same meaning as in Figure 4. In Figure 5, carbon dioxide emissions are normalized by the energy corresponding to each period. As shown in Figure 5, it is easy to see the changes over time in the proportion of carbon energy and carbon-to-energy ratios in energy.

[0057] Next, we analyzed the changes in the proportions of CE, HE, traditional RE, RE, and NE in ENE (total primary energy). The data used for the analysis was disclosed in the reference (Ritchie and Roser (2020)). ENE can be expressed as follows. RE t is the sum of Trad.RE and RE. ENE=CE+HE+RE t +NE···Eq. (3)

[0058] Dividing both sides of equation (3) by ENE and rearranging gives equation (4). (CE / ENE)=1.0-(HE / ENE)-(RE t / ENE)-(NE / ENE) Equation (4)

[0059] Differentiating both sides of equation (4) with respect to time gives equation (5). d(CE / ENE) / dt=-d(HE / ENE) / dt-d(RE t / ENE) / dt-d(NE / ENE) / dt...Equation (5)

[0060] Figure 6 shows the changes in the proportions of CE, HE, traditional RE, RE, and NE in ENE (total primary energy). As shown in Figure 6, it is possible to see the increase and decrease in energy over time.

[0061] Next, we analyzed the relationship between changes in carbon energy and GDP (Gross Domestic Product). Equation (3) can be transformed as follows:

[0062] CE=(CE / GDP)GDP =(ENE / GDP-HE / GDP-RE t / GDP-NE / GDP)GDP···Equation (6)

[0063] Differentiating both sides of equation (6) with respect to time and rearranging them gives equation (7). dCE / dt / CE=d(CE / GDP) / dt / (CE / GDP)+dGDP / dt / GDP =d(ENE / GDP) / dt / (ENE / GDP)(ENE / CE) -d(HE / GDP) / dt / (HE / GDP)(HE / CE) -d(RE / GDP) / dt / (RE / GDP)(RE / CE) -d(NE / GDP) / dt / (NE / GDP)(NE / CE) +dGDP / dt / GDP Equation (8)

[0064] Here, if dt in equation (8) is replaced with Δt, which represents a fixed period of time, equation (8) can be transformed as follows: ΔCE / CE≒Δ(CE / GDP) / (CE / GDP)+ΔGDP / GDP ≒Δ(ENE / GDP) / (ENE / GDP)(ENE / CE) -Δ(HE / GDP) / (HE / GDP)(HE / CE) -Δ(RE / GDP) / (RE / GDP)(RE / CE) -Δ(NE / GDP) / (NE / GDP)(NE / CE) +ΔGDP / GDP Equation (9)

[0065] Using equation (9), we can relate the change in carbon energy per unit of GDP to the change in GDP and the change in energy consumption per unit of GDP.

[0066] Figure 7 shows the change in carbon energy per unit GDP, the change in GDP, and the change in energy consumption per unit GDP. As shown in Figure 7, in order to reduce the change in carbon energy per unit GDP (CE / GDP), it is necessary not only to reduce the change in primary energy per unit GDP (ENE / GDP), but also to reduce the change in hydrogen energy per unit GDP (HE / GDP) and the change in renewable energy per unit GDP (RE t It can be seen that there is also a need to increase the hydrogen energy change per unit of GDP (NE / GDP) and the hydrogen energy change per unit of GDP (NE / GDP).

[0067] Next, to confirm that carbon energy is effective in visualizing carbon dioxide emissions, we created an energy flow diagram that takes carbon energy into account. Figure 8 shows the data used to create the energy flow. Figure 8 uses statistical data from Japan in 2010.

[0068] Figure 9 is a diagram showing energy flows created based on the data shown in Figure 8. The left column in Figure 9 shows primary energy sources. The thickness of the bands coming out of the left column indicates the amount of energy. The breakdown of each band indicates the type of energy produced from the primary energy source. The middle column in Figure 9 shows secondary energy generated from primary energy. The right column in Figure 9 shows where the energy is consumed. As shown in Figure 9, by referring to the flow of carbon energy bands, information can be obtained about the source of carbon energy and when it is emitted as carbon dioxide.

[0069] Figure 10 shows the data used to create the energy flow. Figure 10 uses statistical data from Japan in 2010. Figure 10 also shows a breakdown of the types of energy that generate the electricity shown in Figure 8.

[0070] Figure 11 is a diagram showing energy flows created based on the data shown in Figure 10. The items shown in the left, middle, and right columns of Figure 10 are the same as those in Figure 9. Figure 11 also shows a breakdown of the types of energy in the electricity band. As shown in Figure 11, it is clear how much carbon energy is consumed at the energy consumption destination. In other words, it shows how much carbon dioxide is emitted at the energy consumption destination.

[0071] As described above, according to the embodiment of the present invention, carbon energy, which has a strong correlation with carbon dioxide emissions, can be plotted on the same chart as other energies, allowing for a clearer understanding of the primary energy sources that cause carbon dioxide emissions and the energy consumption destinations that emit the carbon dioxide.

[0072] Throughout this specification, when a part is described as "having" or "comprising" a certain element, this does not mean that it excludes other elements, but that it may further include other elements, unless otherwise specified.

[0073] Furthermore, the term "unit" used in the specification means a unit that processes at least one function or operation, which may be embodied as hardware or software, or as a combination of hardware and software.

[0074] In addition, the components in the above-described embodiment may be replaced with known components as appropriate within the scope of the present invention. Furthermore, the above-described modifications may be combined as appropriate. [Industrial Applicability]

[0075] As described above, according to the present invention, a method for displaying carbon energy and a display device for carbon energy can be provided that can clearly display the amount of carbon dioxide in energy in energy units, and therefore have high industrial utility value.
