Description

Technical Field

[0001] This invention relates to the field of chain carbon management, and more particularly to a whole-supply-chain carbon management method and system for coal-fired power plants coupled with carbon capture and storage. Background Technology

[0002] As global climate change becomes increasingly severe, carbon capture, utilization, and storage (CCUS) technology has become a key pathway for large-scale emission sources such as coal-fired power plants to achieve deep decarbonization. Among these, the safe and permanent storage of carbon dioxide in underground geological structures is the core element in ensuring effective emission reduction. However, existing CCUS project management models typically manage capture, transportation, and storage as independent stages, lacking a synergistic perspective across the entire supply chain. This results in overall inefficiency, high costs, and casts doubt on the authenticity and reliability of carbon emission reductions.

[0003] Existing carbon dioxide transportation scheduling is mostly based on simple distance or economic cost optimization, failing to consider the geological safety attributes and real-time operating conditions of storage facilities as core decision variables. This may result in carbon dioxide being transported to storage facilities with suboptimal geological conditions or under stressful operating conditions, increasing the safety risks of long-term storage. Current valuation methods for carbon sequestration often employ a "one-size-fits-all" approach, relying solely on capture volume and failing to reflect the additional environmental value derived from storage in safer, more stable geological formations. This fails to create a positive incentive in the market to award premiums to high-quality carbon sequestration projects, thus weakening the economic motivation for companies to invest in such projects. The entire data chain, from capture to storage, is fragmented and easily tampered with, lacking a credible traceability system capable of proving its authenticity. This makes it difficult for regulators, investors, and the public to verify whether every ton of carbon dioxide has been truly and permanently stored, hindering the development and international recognition of carbon finance products. Carbon sequestration is a dynamic geological process that can last for thousands of years, while existing certifications are mostly "one-off." Projects lack long-term, periodic audits of the state of the carbon sequestration reservoir after sequestration, as well as mechanisms for dynamic linkage with the value of carbon assets, making it impossible to cope with potential risks of geological changes.

[0004] Therefore, we propose a whole-supply-chain carbon management method and system for coal-fired power plants coupled with carbon capture and storage to solve the above problems. Summary of the Invention

Beneficial effects: The scheduling system can automatically and preferentially guide carbon dioxide to storage facilities with safer geological structures and greater storage potential, significantly improving the millennium safety of storage projects from the source; it integrates scattered storage facilities into a dynamically schedulable "resource network", avoiding local storage capacity shortages or idleness, and maximizing the utilization efficiency of the entire system's stored resources. Carbon assets stored in "golden sites" will receive higher value assessments and form price premiums in the carbon market, thereby establishing economic leverage to incentivize companies to pursue high-quality storage; the consumption of transportation, injection and other processes will be accounted for as "value loss", making the real costs and benefits of the entire chain clear at a glance, and providing accurate data support for investment and operation decisions; It achieves transparency, traceability, and immutability throughout the entire process from capture, transportation, to storage, completely resolving doubts about the authenticity and extraneousness of carbon emission reductions, and clearing obstacles for the development and international recognition of carbon financial products; the integrity verification of the transportation process and the automatic recording of injection events make the carbon asset generation process highly automated and self-verifiable, greatly reducing human intervention and auditing costs. Transforming the "one-time" sealing and certification into dynamic monitoring and value maintenance throughout the entire project lifecycle enables timely responses to long-term changes in geological bodies and ensures the long-term stability of carbon assets. This mechanism transforms carbon assets from static, easily depreciated notes into dynamically managed "digital minerals" with long-term value growth potential, greatly enhancing their attractiveness to long-term investors.

The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein.

[0019] For ease of understanding, the specific process of the embodiments of the present invention is described below. Please refer to [link / reference]. Figure 1 One embodiment of the whole-supply-chain carbon management method for coal-fired power plants coupled with carbon capture and storage in this invention includes: 101. Generate a dynamic geological carbon potential field distribution map: Based on the real-time operating data and pre-assessed geological attribute data of each storage reservoir, calculate and generate a dynamic geological carbon potential field distribution map of the entire region; among which, the geological attribute data includes at least the caprock sealing index and the mineral carbonation potential index. It is understood that the implementing entity of this invention can be a full-supply-chain carbon management system coupled with carbon capture and storage in a coal-fired power plant, or it can be a terminal or a server; the specific implementation is not limited here. This embodiment of the invention will be described using a server as an example.

[0020] Specifically, a basic dataset for the storage reservoirs is constructed: real-time injection pressure and capacity occupancy rate of each storage reservoir are collected as real-time operating condition data, and caprock sealing index and mineral carbonation potential index obtained from pre-assessment are retrieved as geological attribute data, which together constitute the basic dataset for the storage reservoirs. Generate a normalized geological factor: The caprock sealing index and mineral carbonation potential index in the basic dataset of the storage repository are normalized and fused to generate a normalized geological factor that comprehensively characterizes the long-term safety and stability of the storage repository. Calculate the dynamic pressure factor: Based on the real-time injection pressure and capacity utilization rate in the basic dataset of the archive, calculate a dynamic pressure factor that reflects the current receiving capacity and urgency of the archive. Synthetic geological carbon potential field unit: The normalized geological factors and dynamic pressure factors are weighted and synthesized to generate a geological carbon potential field unit value that represents the current comprehensive situation of each reservoir. Generate a dynamic distribution map of the entire region: Visualize and render the geological carbon potential field unit values ​​of all the sealed repositories on the spatial geographic information base map to generate a dynamic distribution map of the geological carbon potential field of the entire region; the distribution map intuitively displays the high and low distribution of the geological carbon potential of each sealed repositories with different colors or contour lines.

[0021] 102. Generate a geological priority scheduling instruction: Using the dynamic geological carbon potential field distribution map as the core input, generate a geological priority scheduling instruction containing a specified target storage facility and transportation path for each batch of carbon dioxide captured from the coal-fired power plant and purified and compressed. Specifically, a list of carbon batches to be dispatched is generated: in response to a coal-fired power plant completing a batch of carbon dioxide capture, purification and compression operations, a list of carbon batches to be dispatched is generated, which includes the unique identifier of the batch, the location of the capture source, the volume and the timestamp. Generate a preferred list of storage repositories: Using the dynamic geological carbon potential field distribution map as the core input, sort all available storage repositories according to the geological carbon potential of each storage repository as represented in the map, and generate a preferred list of storage repositories. Execution path reachability verification: Based on the capture source location information in the carbon batch list to be scheduled, and the preferred list of storage facilities, combined with the real-time topology and status data of the transmission pipeline network, the path reachability and capacity feasibility of each storage facility in the preferred list are verified one by one, and a set of feasible storage facility-path combinations containing the verification results is generated. Determine the optimal comprehensive route: For each combination in the set of feasible storage warehouse-route combinations, comprehensively consider its route transportation cost and the ranking of the target storage warehouse in the storage warehouse preference list, perform multi-objective trade-offs, and determine an optimal combination of storage warehouse and transportation route. Generate and issue a geological priority scheduling instruction: Based on the comprehensive optimal combination of storage tanks and transportation routes, generate a structured geological priority scheduling instruction; the instruction shall at least include the unique identifier of the target storage tank, the specified sequence of transportation route nodes and the expected injection time window, and issue the instruction to the pipeline transportation control system and bind it to the carbon batch to be scheduled.

[0022] 103. Create and bind a digital carbon asset identifier: In accordance with the geological priority scheduling instruction, when a batch of carbon dioxide is injected into the pipeline network, a globally unique digital carbon asset identifier is created and bound to it. This identifier will serve as the unique digital twin of that batch of carbon dioxide in the entire supply chain. Specifically, a core identifier for carbon assets is generated: at the moment when a batch of carbon dioxide begins to be injected into the pipeline network, a globally unique core identifier for carbon assets is generated based on the unique identifier of the batch, the capture source information and the timestamp. Constructing an initial digital twin: The unique identifier of the target storage facility, the specified sequence of transport path nodes, and the expected injection time window in the geological priority scheduling instruction are bound as initial metadata to the core identifier of carbon assets to construct an initial digital twin of this batch of carbon dioxide. Real-time collection and binding of transportation data: During the process of batches of carbon dioxide flowing through the transportation pipeline network, the time, pressure and flow data of each pipeline node and key equipment are collected in real time, and these real-time transportation data are bound to the core identifier of carbon assets and updated to the digital twin. Record injection events and update status: When a carbon dioxide injection start signal is received from the target storage facility, the injection start time, initial injection pressure and carbon asset core identifier are bound together, and the status of the digital twin is updated to "injecting". Generate a complete logistics history: When a confirmation signal for the completion of carbon dioxide injection is received from the target storage facility, the injection completion time, cumulative injection volume, and final injection pressure data are bound to the core identifier of the carbon asset to generate a complete logistics history that includes the entire process from capture and transportation to injection. This history serves as the final state of the digital twin.

[0023] It should be noted that the transportation process integrity verification mechanism is executed after the real-time collection and binding of transportation data: Establish transportation data verification nodes: Set up data verification points at each key node of the transportation pipeline network, collect pressure, flow rate and timestamp data of carbon dioxide batches flowing through the node, and generate node verification data packages; Perform a transport path consistency check: compare the verification data packets of each node with the expected transport path node sequence bound to the initial digital twin, and generate a path consistency check report; Constructing transportation quality assessment indicators: Based on continuous node pressure and flow data, calculate the pressure retention rate and flow stability of carbon dioxide during transportation, and generate transportation quality assessment indicators. Generate a transportation integrity certificate: Based on the integrated route consistency verification report and transportation quality assessment indicators, generate a transportation integrity certificate for this batch of carbon dioxide. Update the digital twin verification status: Link the transportation integrity certificate with the carbon asset digital identifier and update the verification status of the digital twin to mark it as transportation verified.

[0024] 104. Calculate the geological storage value data: After a batch of carbon dioxide is injected into the target storage facility specified by the geological priority dispatch instruction, the geological storage value data of the target storage facility is calculated based on the geological attribute data of the target storage facility and the logistics information recorded by the carbon asset digital identifier. Specifically, determine the base value for storage: based on the current carbon market trading price and policy subsidy standards, determine a base value for storage for this batch of carbon dioxide; Generate a geological value-added factor: retrieve the pre-assessment geological attribute data of the target reservoir, and calculate a geological value-added factor greater than 1 based on its caprock sealing index and mineral carbonation potential index. Calculate logistics process consumption: Based on the complete logistics history, extract data on transportation distance, pressurization energy consumption and injection time, and calculate and generate a comprehensive consumption factor that characterizes the economic and environmental costs of the entire logistics process; Calculate the net value of geological storage: Multiply the base value of storage by the geological value-added factor, and then subtract the value loss corresponding to the comprehensive consumption factor to calculate the net value of geological storage for this batch of carbon dioxide. Generate a value accounting certificate: Combine the net value data of geological reserves with the key parameters of the geological value-added factors and comprehensive consumption factors on which they are based to generate a structured value accounting certificate, and bind it to the digital identifier of the carbon assets of this batch.

[0025] It should be noted that the value tokenization processing mechanism is performed after the step of generating the value accounting certificate: Generate standardized value certificates: Based on the value accounting certificate, extract the net value data and key parameters of geological reserves to generate standardized digital value certificates that conform to international carbon asset standards; Add a unique anti-counterfeiting mark: Add a unique anti-counterfeiting mark based on an encryption algorithm to the standardized digital value certificate, and establish a two-way link between the anti-counterfeiting mark and the carbon asset digital mark; Create divisible trading units: Based on the total value data stated in the standardized digital value certificate, divide it into several divisible trading units with a uniform face value. Each trading unit inherits all the attribute information of the original value certificate. Registering to a carbon asset trading platform: Batch registration of divisible trading units to a designated carbon asset trading platform, generating corresponding platform listing identification codes and trading metadata; Establish a value transfer tracking chain: Link the platform's listing identification code and transaction metadata with the trusted carbon asset ledger to form a complete value transfer tracking chain from the geological storage source to secondary market transactions.

[0026] 105. Register into a trusted carbon asset ledger: Register and record the digital identifier of the carbon asset, its complete logistics and storage history, and geological storage value data together in a distributed trusted carbon asset ledger to form a permanent carbon removal asset record supported by geological evidence.

[0027] Specifically, create an asset record framework: Based on the core identifier of carbon assets, create an initial asset record framework with a standardized structure in the trusted carbon asset ledger; Injecting geological evidence data: The pre-assessed geological attribute data of the target repository, including the caprock sealing index and the mineral carbonation potential index, are injected into the initial asset record framework as key geological evidence data; Binding end-to-end process data: The complete logistics history and value accounting certificate are bound to the asset record framework as inseparable process proof data to form a complete data package to be uploaded to the blockchain; Perform distributed consensus verification: Submit the complete data packet to be uploaded to the distributed network nodes for consensus verification. After successful verification, a block hash value containing a timestamp is generated, which serves as a permanent proof of this carbon asset record. Generate a permanent carbon removal record: Write the complete data packet that has been verified by consensus, along with its block hash value, into a trusted carbon asset ledger to generate a permanent carbon removal asset record that is time-series, immutable, and supported by geological evidence.

[0028] 106. Perform periodic geological audits: For storage facilities that have completed carbon dioxide injection, collect reservoir pressure monitoring data, fluid migration monitoring data, and surface leakage monitoring data at predetermined time intervals, and generate periodic geological audit reports. Assessing the stability of the sealed state: Based on periodic geological audit reports, compare the current state of the sealed reservoir with the baseline state at the time of injection completion, and evaluate and generate a sealed state stability index; Dynamically update asset value: Based on the stability index of the storage status, dynamically adjust the net value data of geological storage to generate an asset value update data package; Generate asset status update records: Integrate periodic geological audit reports, storage status stability index and asset value update data packages to generate asset status update records; Maintaining a trusted asset ledger: Asset status updates are recorded and appended to the permanent carbon removal asset record through a distributed consensus mechanism, enabling continuous value maintenance and status tracking of carbon assets throughout their entire lifecycle.

[0029] Specifically, based on periodic geological audit reports, the current state of the storage facility is compared with the baseline state at the time of injection completion to assess and generate a storage state stability index, including: Identify the drift of key geological parameters: Extract reservoir pressure distribution data, caprock strain monitoring data, and carbon dioxide plume boundary data from periodic geological audit reports, compare them with the baseline state data established when the injection is completed, and identify the drift of key geological parameters. Assessing the risk of multi-parameter coupling: Based on the drift of multiple key geological parameters, assess their coupling effect within the storage system and generate a comprehensive risk level assessment result; Calculate the decay rate of storage effectiveness: Based on the comprehensive risk level assessment results and combined with the original geological attribute data of the storage facility, calculate the decay rate of effectiveness of the current storage state relative to the ideal storage state; Generate a stability quantification index: Map the storage performance decay rate to a preset stability scale to generate a quantifiable storage state stability index. Establish a risk warning trigger mechanism: When the stability index of the sealed status is lower than the preset threshold, a risk warning report containing a specific risk description and suggested disposal measures will be automatically generated, and this report will be used as an important part of the asset status update record.

[0030] In this embodiment of the invention, by generating a dynamic geological carbon potential field distribution map and comprehensively considering real-time operating data and pre-assessed geological attribute data, a comprehensive and dynamic evaluation of the carbon sequestration facilities is conducted. This breaks through the limitations of traditional single static evaluation and enables real-time monitoring of the long-term safety, stability, current receiving capacity, and operational urgency of each facility. This provides a scientific basis for carbon dioxide scheduling, improves the utilization efficiency of the facilities, and reduces storage risks. Using the dynamic geological carbon potential field distribution map as the core, combined with path accessibility verification and multi-objective trade-offs, a geological priority scheduling instruction is generated to achieve precise scheduling from coal-fired power plants to the facilities. By comprehensively considering geological conditions, transportation costs, and facility priorities, this ensures that carbon dioxide can be transported to the most suitable facility via the optimal path, reducing transportation costs and improving overall storage efficiency. A globally unique digital carbon asset identifier is created and bound to each batch of carbon dioxide, constructing a digital twin. Transportation data is collected and bound in real time, recording a complete logistics history. This achieves traceability of carbon dioxide throughout the entire supply chain, providing reliable data support for carbon asset management and trading, and enhancing the transparency and credibility of carbon assets. Based on the geological attribute data of the target storage facility and the logistics information recorded by the carbon asset digital identifier, the net value of the geological storage is calculated by comprehensively considering the storage benchmark value, geological value-added factors, and consumption during the logistics process. This accurately assesses the economic value of carbon dioxide geological storage, providing a scientific basis for carbon asset valuation and trading, and promoting the development of the carbon market. Transforming value accounting certificates into standardized digital value vouchers, attaching unique anti-counterfeiting marks, creating divisible trading units and registering them to carbon asset trading platforms establishes a value transfer tracking chain, improving the standardization and security of carbon asset trading, facilitating the circulation and trading of carbon assets, and promoting the active and healthy development of the carbon market. Registering carbon asset digital identifiers, logistics and storage history, and geological storage value data into a distributed storage trusted carbon asset ledger forms a permanent carbon removal asset record supported by geological evidence, ensuring the immutability and traceability of carbon asset records, providing reliable technical support for the full life cycle management of carbon assets, and enhancing the credibility and market acceptance of carbon assets.

[0032] In this embodiment of the invention, a geological priority scheduling instruction is generated based on a dynamic geological carbon potential field distribution map. This fully considers the real-time operating conditions and geological attributes of each storage facility, enabling precise selection of carbon dioxide storage locations, avoiding blind storage, improving storage efficiency and safety, and reducing storage costs and risks. A globally unique digital carbon asset identifier is created and bound to each batch of carbon dioxide, allowing for the tracking of logistics information throughout the entire process from capture, purification, compression, transportation, and storage. This ensures information transparency and traceability, effectively preventing carbon asset loss and data falsification. The geological storage value data is calculated based on the geological attribute data of the target storage facility and the logistics information recorded by the carbon asset digital identifier, making the calculation results more scientific and accurate. This provides a reliable basis for carbon asset pricing and trading, promoting the healthy development of the carbon market. The carbon asset digital identifier, complete logistics and storage history, and geological storage value data are jointly registered and recorded in a trusted carbon asset ledger, forming a permanent carbon removal asset record, protecting carbon asset rights, enhancing the credibility and stability of carbon assets, and providing strong support for carbon emission reduction efforts.
