2. Integration of “CDR + AI”
The integration of CDR Technology and Artificial Intelligence (AI) offers several potential advantages, including four parts as follows:
2.1. Accurate Carbon Emissions Assessment
By combining CDR technology and AI, it becomes possible to accurately assess and quantify carbon emissions.
Figure 5 shows an overview of the thematic dimensions included in the technical feasibility assessment of CDR removal. AI algorithms can analyze large amounts of data from various sources, including CDR facilities, industrial processes, and energy consumption patterns, to provide more precise estimations of carbon emissions. This can help in identifying high-emission areas, tracking progress towards emission reduction goals, and informing policy decisions
[25][18].

AI algorithms can integrate and analyze data from multiple sources, including emissions inventories, satellite imagery, sensor networks, and industry-specific data, to gain a comprehensive understanding of emissions across different sectors and regions
[26][19]. By analyzing emissions-related data, AI can identify the spatial and temporal patterns of emissions, such as emission hotspots or areas with significant emission fluctuations, and pinpoint the high-emission areas that may require targeted interventions
[27][20]. Machine learning techniques enable AI models to recognize emission patterns and make predictions based on historical data
[28][21], identifying areas with a higher likelihood of being high-emission areas
[29,30][22][23].
Satellite imagery provides valuable information on greenhouse gas concentrations, land-use changes, and industrial activities
[31,32][24][25], which AI algorithms can process and analyze to identify regions with higher emissions and track changes over time
[33][26]. Integrating data from sensors and IoT devices enables real-time monitoring of emissions, facilitating the identification of areas experiencing sudden spikes or persistent high emissions
[34,35][27][28]. By visualizing emissions data spatially and using geospatial analysis techniques, AI can provide intuitive representations of high-emission areas
[36,37][29][30]—making it easier for policymakers and stakeholders to identify regions that require targeted mitigation strategies
[38][31].
By leveraging these capabilities, AI algorithms can assist in identifying high-emission areas, providing valuable insights into the sources and patterns of emissions. This information can guide policymakers in developing targeted interventions, implementing emission reduction measures, and prioritizing areas for mitigation efforts.
2.2. Optimized Energy System Configuration
AI algorithms can optimize the integration of CDR technology into energy systems by analyzing data on energy demand, renewable energy generation
[39][32], and other factors to identify the most efficient and cost-effective ways to reduce carbon emissions and improve overall system efficiency
[40,41][33][34]. By maximizing the use of renewable energy sources, AI can help reduce carbon emissions.

AI algorithms can analyze extensive datasets related to energy demand, renewable energy generation, grid infrastructure, and other relevant factors
[42,43][35][36]. By processing this data, AI models can build sophisticated models that capture the complexities of an energy system including the interplay between different energy sources, demand patterns, and carbon emissions
[40,44][33][37]. These models enable scenario analysis and optimization to identify efficient and cost-effective configurations for integrating CDR technology
[45][38]. Considering factors such as energy demand, renewable energy availability, storage capacities, and carbon removal targets, AI algorithms simulate and evaluate different system configurations
[46,47][39][40]. This facilitates the identification of optimal solutions that maximize renewable energy use, minimize carbon emissions, and achieve specific energy and carbon removal objectives.
AI algorithms also optimize demand-side management strategies by analyzing energy demand patterns
[12,48][12][41]. By leveraging machine learning techniques, AI identifies demand response opportunities, predicts peak energy demand periods, and optimizes the scheduling of energy-consuming activities
[49,50][42][43]. This helps balance energy supply and demand, reduce reliance on fossil fuel-based energy generation, and increase the integration of renewable energy and CDR technologies. AI enhances the accuracy of renewable energy forecasting by analyzing historical weather data, renewable energy generation data, and other variables
[51,52][44][45]. Accurate predictions of renewable energy availability enable the optimization of CDR facility scheduling and operation, aligning them with high renewable energy generation and low grid demand
[53,54][46][47]. Furthermore, AI algorithms optimize energy system configurations by analyzing historical and real-time data on energy supply and demand, market prices, weather conditions, and other factors
[55][48]. This analysis identifies opportunities for energy storage deployment, demand shifting, and smart grid management
[56][49], ensuring stability, accommodating intermittent renewable energy sources, and effectively integrating CDR technologies
[39][32].
By leveraging AI capabilities, energy system operators, policymakers, and stakeholders can optimize energy system configurations to maximize CDR technology benefits. This includes minimizing carbon emissions, maximizing renewable energy use, and improving overall system efficiency and resilience.
2.3. Real-Time Monitoring and Scheduling of CDR Facilities
AI enables the real-time monitoring and adaptive control of CDR facilities. By analyzing data from sensors, AI algorithms can continuously monitor the performance and operation of CDR facilities, detecting any anomalies or inefficiencies
[57][50]. This allows for timely adjustments and optimizations, ensuring optimal utilization of resources and maximization of the carbon removal capacity of the facilities.

AI algorithms integrate data from various sensors and monitoring devices installed in CDR facilities
[59,60][51][52]. This includes parameters like temperature, pressure, flow rates, and capture efficiency. By continuously analyzing real-time data, AI monitors the performance of CDR facilities, detects anomalies or deviations from optimal conditions, and alerts operators to potential issues
[61,62][53][54]. Anomaly detection techniques help identify abnormal behavior or malfunctions
[63][55], triggering alarms or notifications by comparing real-time sensor data with historical patterns and predefined thresholds. Operators can take immediate corrective actions, minimizing disruptions in the carbon removal process. AI also predicts maintenance needs and schedules proactive maintenance activities, optimizing facility availability and reliability
[64][56].
AI dynamically adjusts CDR facility operations based on real-time data and changing conditions. By monitoring factors like energy availability, carbon capture efficiency, and storage capacity, AI optimizes scheduling and resource allocation. This enables adaptive control strategies that maximize carbon removal capacity, optimize energy consumption, and respond to fluctuations in renewable energy generation or demand. AI optimizes resource allocation within CDR facilities, considering real-time data on energy availability, cost, and carbon removal targets. This determines the most efficient allocation of resources for optimal carbon removal performance, minimizing costs while maximizing capacity. AI integrates with energy grid data and market signals to schedule CDR facilities. Considering electricity prices, demand peaks, and renewable energy availability, AI schedules carbon removal processes during periods of low electricity demand or high renewable energy availability. This maximizes renewable energy utilization, reduces costs, and aligns carbon removal activities with grid conditions.
