[0013] (Overview of the asset management system) As shown in Figure 1, the asset management device 10 according to the first embodiment of this disclosure has the following functional configuration, which consists of a combination of hardware such as one or more computers such as a personal computer or tablet terminal, and software such as a program executed by the computer. Specifically, the asset management device 10 includes an input unit 11, a collection unit 12, a selection setting unit 13, an optimization unit 14, an output unit 15, and a storage unit 16. The asset management device 10 according to this embodiment is a device for appropriately proposing and managing equipment configurations when transitioning from existing equipment to equipment that achieves greater decarbonization in industrial systems such as plants. Now, with reference to Figure 2, an example of an industrial system to which the asset management device 10 is applied will be described.

[0014] (Industrial Systems) As shown in Figure 2, the industrial system 1 to which the asset management device 10 is applied comprises, for example, a co-firing control device 101, a hydrogen / ammonia supply device 102, a fossil fuel supply device 103, valves 104 and 105, a combustion device 106, an exhaust gas treatment device 107, and a monitoring device 110. In Figure 2, solid black arrows indicate the flow of fuel, solid white arrows indicate the flow of exhaust gas, dashed arrows indicate the flow of control signals, and chain-dashed arrows indicate the flow of sensor signals. The industrial system 1 is, for example, a facility such as a plant, a mobile object such as a ship, or the like.

[0015] The hydrogen / ammonia supply device 102 supplies hydrogen or ammonia (fuel ammonia) 121 to the combustion device 106 via the valve 104. The hydrogen / ammonia supply device 102 includes, for example, a hydrogen production device, a hydrogen storage tank, an ammonia production device, an ammonia storage tank (storage device), and the like. Note that the hydrogen / ammonia supply device 102 may be a device that supplies only hydrogen, a device that supplies only ammonia, or a device that supplies both hydrogen and ammonia.

[0016] The fossil fuel supply device 103 supplies a fossil fuel 122 such as LNG (liquefied natural gas), coal, or the like to the combustion device 106 via the valve 105. The fossil fuel supply device 103 includes a fossil fuel storage device and the like.

[0017] The combustion device 106 includes, for example, one or more of a gas turbine (GT), a boiler, a power generation engine, or a marine engine, and co-fires hydrogen or ammonia 121 supplied from the hydrogen / ammonia supply device 102 and fossil fuel 122 supplied from the fossil fuel supply device 103.

[0018] The exhaust gas 123, which includes the exhaust gas emitted from the combustion device 106 and the exhaust gas emitted from the hydrogen / ammonia supply device 102, is input to the exhaust gas treatment device 107. However, if the hydrogen / ammonia supply device 102 does not emit exhaust gas (for example, if hydrogen or ammonia is produced in a hydrogen or ammonia production device that does not emit exhaust gas), or if there is no hydrogen or ammonia production device, the hydrogen / ammonia supply device 102 does not emit exhaust gas.

[0019] The exhaust gas recovery system 107 includes a CO2 recovery unit, a denitrification unit, a desulfurization unit, etc., and recovers CO2, removes nitrogen oxides, and removes sulfur from the input exhaust gas 123. The CO2 (108) recovered by the exhaust gas recovery system 107 is effectively utilized or stored and is not released into the atmosphere. On the other hand, the treated exhaust gas (109) processed by the exhaust gas recovery system 107 is released into the atmosphere, for example, through a chimney. The CO2 (109a) contained in the treated exhaust gas (109) is at a low concentration.

[0020] The monitoring device 110 acquires sensor signals indicating predetermined physical quantities measured using various sensors in the hydrogen / ammonia supply device 102, combustion device 106, exhaust gas treatment device 107, etc., as well as control signals indicating control status, control commands, etc. (hereinafter, sensor signals and control signals are collectively referred to as operating status signals), and outputs the operating status signals to the co-firing control device 101. Examples of sensor signals acquired by the co-firing control device 101 include the flow rate of fuel, exhaust gas, etc., temperature, pressure, output, rotational speed, CO2 concentration, etc.

[0021] The co-firing control device 101 receives the operating status signal output by the monitoring device 110, determines a command value for the co-firing ratio based on the operating status signal, notifies the hydrogen / ammonia supply device 102, combustion device 106, exhaust gas treatment device 107, etc. of the command value for the co-firing ratio, and adjusts the co-firing ratio by controlling valves 104 and 105, etc. If the hydrogen / ammonia supply device is equipped with a hydrogen / ammonia production device, the hydrogen / ammonia supply device 102 operates in accordance with the command value for the co-firing ratio. In addition, the co-firing control device 101 also controls the combustion of the combustion device 106 according to the co-firing ratio. The co-firing ratio is a value that represents the mixing ratio of fossil fuel and hydrogen or ammonia, and can be, for example, the ratio of the amount of heat of hydrogen or ammonia to the total amount of heat of the fuel input to the combustion device 106. The co-firing control device 101 outputs a preset command value for the co-firing ratio according to the operating status of, for example, the hydrogen / ammonia supply device 102, combustion device 106, exhaust gas treatment device 107, etc.

[0022] (System under evaluation) Next, referring to Figure 3, the system to be evaluated by the asset management device 10 shown in Figure 1 in the industrial system 1 shown in Figure 2 will be described. In this embodiment, the system to be evaluated consists of multiple devices that are considered when the asset management device 10 proposes the optimal combination. Figure 3 shows the hydrogen / ammonia supply device 102, the fossil fuel supply device 103, the combustion device 106, and the exhaust gas treatment device 107 from the configuration shown in Figure 2. The exhaust gas treatment device 107 shown in Figure 3 is also equipped with a CO2 recovery device 111. The CO2 recovery device 111 recovers CO2 from the exhaust gas 123 and supplies it to a device that utilizes CO2, or stores the CO2 (for example, transports it to a predetermined location and isolates it in a geological formation). Furthermore, the exhaust gas treatment device 107 may also have an option to enhance the removal of components other than CO2, such as NOx. In the example shown in Figure 3, the system to be evaluated by the asset management device 10 (hereinafter referred to as the evaluation system) 20 includes the hydrogen / ammonia supply device 102, the combustion device 106, and the exhaust gas treatment device 107.

[0023] (Configuration and operation of the asset management system) Next, with reference to Figures 1 and 4 to 9, the configuration and operation example of the asset management device 10 shown in Figure 1 will be described.

[0024] The input unit 11 receives, for example, the "equipment status" of the system under evaluation 20, "equipment information" representing usable equipment, and "requirements" for the updated or new system under evaluation 20, in response to input operations by an operator. The input unit 11 stores the entered "equipment status," "equipment information," and "requirements" in the storage unit 16. The storage unit 16 is composed of, for example, one or more storage devices.

[0025] The "Equipment Status" of the system under evaluation 20 is information about the existing hydrogen / ammonia supply unit 102, combustion unit 106, and exhaust gas treatment unit 107 that are subject to replacement, and is information about the equipment that serves as the basis for the asset management unit 10 when proposing the configuration of the new equipment. If there is no existing equipment and new equipment is to be installed, inputting "Equipment Status" is not required (for example, enter "None" for "Equipment Status"). Figure 5 shows example E1 of "Equipment Status" when industrial system 1 is a power plant, combustion unit 106 is a gas turbine (GT) power generation unit, hydrogen / ammonia supply unit 102 supplies hydrogen, and exhaust gas treatment unit 107 is a CO2 recovery unit 111. Example E1 of "Equipment Status" shown in Figure 5 shows that industrial system 1 is a power plant, and as information about the power plant, it includes information about CO2 emissions. This information about CO2 emissions serves as a comparison standard for the combination of equipment after replacement, for example. In addition, example E1 of "Equipment Status" includes performance information, maintenance information, and model information for the GT power generation unit as information about the combustion unit 106. Performance information includes, for example, information on power generation performance. Maintenance information includes information on the timing and content of maintenance for the equipment (for example, information on the timing and content of replacement and maintenance of equipment and parts, and information on the timing and content of software updates such as control programs (hereinafter the same)). Model information represents information that simulates a model of the process components of the GT power generation equipment. By using model information, for example, it is possible to estimate the operating state of the GT power generation equipment (states such as output, efficiency, temperature, and pressure) or to estimate heat exchange between other components (hereinafter the same applies to model information). There are no limitations on the method of creating the model, and existing technologies can be used. In addition, example E1 of "Equipment Status" includes performance information, maintenance information, and model information for the hydrogen production equipment and performance information, maintenance information, and model information for the hydrogen storage tank as information for the hydrogen / ammonia supply equipment 102. Performance information includes, for example, information on hydrogen production capacity and tank storage capacity. Maintenance information includes information on the timing and content of maintenance for the equipment.Furthermore, example E1 of "Equipment Status" includes information about the exhaust gas treatment device 107, such as performance information, maintenance information, and model information for the CO2 recovery device. Performance information includes, for example, information about the recovery capacity of the CO2 recovery device. Maintenance information includes information about the timing and content of maintenance for the device.

[0026] Furthermore, "equipment information," which represents usable equipment, includes information on equipment that is usable at the time when equipment replacement is scheduled, and information on equipment for which the time of usability is clearly defined. However, information on equipment for which the time of usability is clearly defined does not need to be included. It may also include information on equipment for which the time of usability has a certain degree of flexibility (or is not necessarily clear). Note that equipment replacement means replacement (replacement) or new installation (additional installation, etc.) of equipment or parts, software changes, etc. "Equipment information" may include information such as, for example, that a GT power generation system capable of handling a co-firing rate of up to 30% is usable at a certain time A, and a GT power generation system capable of handling a co-firing rate of up to 50% is usable at a later time B than time A. Figure 6 shows example E2 of "equipment information." Example E2 of "equipment information" shown in Figure 6 includes, for example, performance information, cost, possible installation time, and model information for GT power generation system A. Furthermore, example E2 of "Equipment Information" also includes performance information, cost, availability period, and model information for GT power generation unit B, the combustor upgrade of GT power generation unit A, CO2 capture unit A, CO2 capture unit B, hydrogen production unit A, and hydrogen production unit B.

[0027] Furthermore, the "requirements" for the updated or newly evaluated system 20 include information specifying the objective function and constraints used in the optimization process by the optimization unit 14 described later. Alternatively, the "requirements" may include information specifying constraints without including information specifying the objective function. In this case, the objective function can be set in advance, for example. Figure 7 shows an example of "requirements" E3. In example "requirements" E3, the objective function can be, for example, the CO2 emission reduction rate, the cost efficiency of CO2 reduction, the profit generated per unit of CO2 emissions, or the total carbon dioxide emissions of the value chain. These CO2 emission reduction rate, cost efficiency of CO2 reduction, profit generated per unit of CO2 emissions, and total carbon dioxide emissions of the value chain are all indicators related to the carbon dioxide emitted by the evaluation system 20. Note that in the optimization process by the optimization unit 14 described later, one or more indicators can be set as the objective function. In addition, indicators required for industrial systems, such as power generation output and energy efficiency as shown in the constraints, may be combined with the objective function, or the objective function and constraints may be replaced. The setting of such optimization problems can be customized by the owners of industrial plants, etc. Each indicator is calculated based on all the equipment constituting the system under evaluation 20 (for example, CO2 emissions are calculated as the sum of all equipment).

[0028] The CO2 emission reduction rate is an indicator that measures reduction efforts, and can be calculated using the following formula: (CO2 emission reduction rate) = ((CO2 emissions without countermeasures) - (CO2 emissions with countermeasures)) ÷ (CO2 emissions without countermeasures). Here, "without countermeasures" refers to the period before the update, and "with countermeasures" refers to the period after the update.

[0029] CO2 reduction cost efficiency is an indicator that measures the effectiveness of countermeasures, and can be calculated using the formula: (CO2 reduction cost efficiency) = ((CO2 emissions without countermeasures) - (CO2 emissions with countermeasures)) ÷ (CO2 countermeasure costs).

[0030] The profit generated per unit of CO2 emissions is an indicator that measures how much CO2 emissions, as an economic cost, are reduced, and can be calculated using the formula: (profit generated per unit of CO2 emissions) = (profit generated) ÷ (CO2 emissions with countermeasures). Here, the profit generated is the economic benefit obtained in conjunction with the CO2 emissions of the CO2 emissions with countermeasures.

[0031] Total value chain carbon dioxide emissions are an indicator that measures carbon dioxide emissions across the entire value chain. For example, if hydrogen or ammonia is not produced in the plant but procured from external sources, it includes the CO2 emissions from manufacturing, transportation, etc., as well as CO2 emissions from external sources.

[0032] Furthermore, Figure 7 shows that in example E3 of the "Requirements," the constraints include a minimum power output, a minimum energy efficiency, a maximum CO2 emission limit, maximum limits on other gas components, a maximum equipment cost, and a maximum fuel cost. The updated or new equipment configuration is required to meet these requirements.

[0033] Furthermore, the data collection unit 12 collects market information such as fuel prices, electricity prices, and carbon taxes from a designated external server, for example, in response to operator input operations. This may include information on legal regulations, such as environmental regulations and reduction targets set by countries and industries. This information may also be presented as projected future values.

[0034] Furthermore, if the updated or newly evaluated system 20 includes a hydrogen / ammonia supply unit 102, a combustion unit 106 that co-fires fossil fuels with hydrogen or ammonia, and a CO2 recovery unit 111 that recovers carbon dioxide from the exhaust gas 123 of the combustion unit 106, the selection setting unit 13 sets one or more combinations of the hydrogen / ammonia supply unit 102, the combustion unit 106, and the CO2 recovery unit 111 as options based on the "equipment status" and "equipment information". The selection setting unit 13 determines the combinations of multiple pieces of equipment included in the "equipment status" and multiple pieces of equipment included in the "equipment information," for example, according to the operator's input, and sets one or more combinations of equipment that will be selected as options for evaluation. The equipment combinations can be, for example, a combination of existing equipment and new equipment, the addition of new equipment to existing equipment, or the replacement of existing equipment with new equipment. Furthermore, the option setting unit 13 may set multiple options (multiple stepwise options with different adoption timings) to gradually improve the co-firing ratio based on maintenance information and / or market information of the system under evaluation 20.

[0035] Furthermore, the optimization unit 14 sets an objective function and constraints based on predetermined indicators and "requirements" related to the carbon dioxide emitted by the system under evaluation, and evaluates one or more sets of options set by the option setting unit 13 to find the option that minimizes or maximizes the objective function. The optimization unit 14 may also find the option that minimizes or maximizes the objective function, and the recommended co-firing ratio of hydrogen or ammonia to fossil fuels. It is also possible to virtually input fluctuations in the prices of hydrogen, ammonia, fossil fuels, and electricity using market information and evaluate fluctuations in the recommended co-firing ratio. In addition, numerical values ​​representing the overall performance of the options used to determine the constraints (output, efficiency, emissions, etc.), numerical values ​​for calculating indicator values, etc., can be calculated, for example, based on simulation results using model information or information collected by the collection unit 12. Furthermore, if the option setting unit 13 sets multiple options in stages, the optimization unit 14 finds multiple options that minimize or maximize the objective function for each stage.

[0036] Furthermore, the output unit 15 outputs information indicating the selected options based on the optimization processing results of the optimization unit 14 to a predetermined output device. Figures 8 and 9 show examples of output results from the output unit 15. In example E4 of the output results shown in Figure 8, the combination of equipment configuration consisting of GT power generation device A, hydrogen storage tank A, and CO2 recovery device A is selected as the optimal combination. The CO2 emission reduction rate used as an indicator and the recommended co-firing rate are also shown. On the other hand, Figure 9 shows an example of the optimization processing results at a time when it became possible to improve the co-firing rate by upgrading the combustor of GT power generation device A. In example E5 of the output results shown in Figure 9, the combination of equipment configuration consisting of the upgraded combustor of GT power generation device A, hydrogen production device A, and CO2 recovery device B is selected as the optimal combination. The CO2 emission reduction rate used as an indicator and the recommended co-firing rate are also shown. Example E5 of the output results shown in Figure 9 corresponds to a case where, for example, the CO2 emission reduction rate is improved by upgrading the combustor of GT power generation device A to increase the co-firing ratio, and combining hydrogen production by hydrogen production device A with CO2 recovery device B (CO2 recovery device B is suitable for removing CO2 whose concentration has decreased, for example, in exhaust gas with a higher co-firing ratio than CO2 recovery device A).

[0037] Next, an example of the operation of the asset management device 10 will be described with reference to Figure 4. When the process shown in Figure 4 is started, first, usable equipment information is referenced from the database (step S101). Next, the input unit 11 inputs the equipment status of the system to be evaluated 20 (step S102). Next, the input unit 11 inputs the requirements of the system to be evaluated 20 (step S103). Next, the collection unit 12 collects market information, etc. (step S104). At this point, future predicted values ​​of market information may be virtually input. Next, the selection setting unit 13 sets the equipment configuration options (step S105). Next, the optimization unit 12 selects one of the options (step S106). Next, the optimization unit 12 sets the recommended co-firing ratio according to, for example, the operator's input operation (step S107). Next, the optimization unit 12 calculates the overall performance of the options (step S108). Next, the optimization unit 12 checks for compliance with the requirements (step S109). If the option is not suitable (Step S110: NO), the optimization unit 12 resets parameters such as the recommended co-firing ratio as necessary (Step S111) and recalculates the overall performance of the options (Step S108). If the option is suitable (Step S110: YES), the optimization unit 12 determines whether all options have been evaluated (Step S112). If all options have not been evaluated (Step S112: NO), the optimization unit 12 selects the next option (Step S106) and repeats the process from Step S107 onwards. If all options have been evaluated (Step S112: YES), the output unit 15 selects the option with the best index value, outputs information indicating the selected option (Step S113), and terminates the process shown in Figure 4.

[0038] (Effects, etc.) In this embodiment, the selection setting unit 13 sets the combination of the hydrogen / ammonia supply unit 102, the combustion unit 106, and the CO2 recovery unit 111 as options, based on the existing equipment status of the system under evaluation 20 and equipment information representing usable equipment, assuming that the updated or new system under evaluation 20 includes a hydrogen / ammonia supply unit 102, a combustion unit 106 that co-fires fossil fuels with hydrogen or ammonia, and a CO2 recovery unit 111 that recovers carbon dioxide from the exhaust gas of the combustion unit 106. The optimization unit 14 sets an objective function and constraints based on predetermined indicators and requirements related to the carbon dioxide emitted by the system under evaluation 20, and uses the options as evaluation targets to find the option that minimizes or maximizes the objective function. With this configuration, for example, it is possible to transition from existing equipment to equipment that achieves greater decarbonization. Furthermore, according to this embodiment, optimal asset management for utilizing hydrogen and ammonia toward achieving decarbonization targets can be implemented.

[0039] Furthermore, according to this embodiment, in thermal power plant co-firing asset management, it is possible to gradually transition to decarbonized fuels (hydrogen or ammonia) starting from existing facilities that use fossil fuels. In addition, the system consisting of at least the processes of decarbonized fuel supply, combustion, and gas treatment (including monitoring) can be evaluated. Note that decarbonized supply equipment can include not only manufacturing equipment but also storage and transportation equipment such as tanks. In addition, maintenance information can be easily referenced, which is useful when planning upgrades / replacements to the latest technologies, taking into account maintenance elements such as equipment deterioration. Furthermore, the objective function for equipment optimization can include CO2 emission reduction rate, CO2 reduction cost efficiency, and profit generated per unit of CO2, and optimization can be performed using one of these or multiple objectives. In addition, CO2 emissions from the entire value chain, such as fuel production, can be considered as constraints for equipment optimization. In this embodiment, constraints on the decarbonized fuel supply chain (such as supply volume and timing) may also be considered. For example, if there are challenges in the supply volume or economics of decarbonized fuel, especially in the initial introduction period of equipment that supports co-firing, a decarbonized equipment configuration can be proposed by combining it with other decarbonization technologies such as CO2 capture. Furthermore, in cost evaluation, it is desirable to consider factors that affect the business, such as carbon taxes and emissions trading, and to update the evaluation as needed. In addition, when performing simulations that model process components to achieve optimization, it is also advisable to optimize heat exchange between the component equipment.

[0040] The first embodiment provides a concrete equipment plan and effect predictions, which can help operators of the system under evaluation make appropriate investment decisions. Furthermore, by considering the exchange of fuel, heat, and electricity between processes, the overall economic efficiency of the system can be improved.

[0041] <Second Embodiment> Next, an asset management device, management method, and program, including a proposed equipment configuration according to the second embodiment of this disclosure, will be described with reference to Figure 10. Figure 10 is a block diagram showing an example configuration of the evaluation system according to the second embodiment of this disclosure.

[0042] In the first embodiment, the hydrogen / ammonia supply device 102 includes at least one of the following: a production device, a storage device, etc. On the other hand, in the second embodiment, in the evaluation target system 20a (corresponding to the evaluation target system 20 in Figure 3), the hydrogen / ammonia supply device 102 includes a hydrogen / ammonia production device 112 and a hydrogen / ammonia transport and storage device 113. The hydrogen / ammonia transport and storage device 113 includes a transport device (such as a transport ship) and a storage device for hydrogen or ammonia. In other words, in the second embodiment, the hydrogen / ammonia supply device 102 is a device that assumes that hydrogen / ammonia is transported from a distant production device to a storage device near the combustion device 106 by a transport ship, etc. In the second embodiment, by explicitly defining the hydrogen / ammonia production device 112 and the hydrogen / ammonia transport and storage device 113 as separate devices, it is possible to easily define various combinations of hydrogen / ammonia production devices 112 and various combinations of hydrogen / ammonia transport and storage devices 113. However, if there are multiple equipment owners, asset management will be carried out by each, and CO2 emission information, etc., will be shared.

[0043] The configuration of the asset management device in the second embodiment is basically the same as the configuration of the asset management device 10 in the first embodiment shown in Figure 1. In decarbonization supply chain management, the evaluation of decarbonization is discussed for the entire value chain, including going back to the fuel manufacturing stage. Therefore, in the second embodiment, optimization can be performed in the development planning and operation of power generation facilities, taking this discussion into consideration. Furthermore, at this stage, the supply volume of decarbonized fuels may be constrained by the development status of supply infrastructure, etc., and it is desirable to take this into consideration as well.

[0044] In the first embodiment, if a manufacturing facility is provided, and in the second embodiment, hydrogen production can be evaluated based on reforming from fossil fuels and biomass, CO2 capture needs in the purification of by-product gases of industrial processes such as coke ovens, and production by water electrolysis or pyrolysis using renewable energy. By adding information corresponding to these configurations to constraints, for example, these configurations can be evaluated (the same applies hereinafter). In ammonia production, for example, in addition to the Haber-Bosch process, new synthesis methods by catalyst development can be considered. In transportation, infrastructure such as pipelines, transport ships, and receiving terminals can be included as components. Furthermore, safety measures such as preventing leaks and malfunctions may be considered for equipment such as tanks, pumps, and compressors. In addition, transportation of hydrogen by liquefaction or organic hydrides is also being considered, and these may be taken into consideration. Furthermore, liquefied ammonia is attracting attention as a hydrogen carrier and could become a common technology for hydrogen and ammonia, and this technology may be taken into consideration. In addition, transportation for the effective use or storage of captured CO2 may also be considered. Furthermore, for combustion equipment, operation using hydrogen and ammonia combustion may be considered, as well as GTCC (Gas Turbine Combined Cycle), boilers, gas engines, fuel cells, ships, etc. Related equipment such as cogeneration using waste heat generated by power generation may also be considered. In this case, the waste heat can also be used for CO2 capture. In addition, the synthesis of useful substances such as methanol in hydrogen and ammonia production can be considered. Furthermore, a wide range of industrial applications using hydrogen, such as hydrogen-reduced ironmaking, are being investigated, and this technology may also be considered. In terms of transportation, since fuel can be shared with hydrogen-powered vehicles and ammonia-powered ships, consideration may be given to improving operational efficiency by coordinating supply and demand through infrastructure such as hydrogen stations. Regarding the effective utilization and storage of CO2, the captured CO2 may be used for the synthesis of chemical products or mineralization, and elements such as underground or underwater storage may also be considered.

[0045] (Effects and workings of the second embodiment) Because it can handle the entire value chain, it can evaluate the ability to predict and avoid risks such as reduced operating rates due to fuel supply shortages. Furthermore, it improves the effectiveness and reliability of decarbonization measures.
