Direct air capture (DAC) systems—energy-intensive yet dispatchable and modular—offer a promising solution for consuming curtailment while enabling negative emissions. However, the integration of DAC with RES remains underexplored. Specifically, DAC systems lack sufficient flexibility to accommodate intermittent energy supplies, stemming from inadequate temporal resolution of operational strategies and overly rigid operational assumptions. Moreover, their operation relies on historical data, lacking real-time control and coordinated scheduling with power plants. To bridge this gap, this study proposes a multi-timescale optimization scheduling framework that enables minute-level real-time control of modular DAC systems co-located with RES power plants. The approach uniquely integrates transferable and curtailable flexible operation modes within a two-phase scheduling system—combining day-ahead planning with intraday rolling optimization—while incorporating power forecast data from RES plants to eliminate perfect-foresight assumptions inherent in retrospective optimization, thereby establishing the first implementable real-time controlled co-dispatch architecture for synergistic RES-DAC integration. A case study based on real-world data from an 850 MW wind farm demonstrates that this approach can reduce daily system operation costs by a factor of five, increase the utilization rate of curtailed electricity to over 90%, and capture 1.5 million tons of CO₂ annually. Collectively, these outcomes establish an effective scheduling solution for RES-DAC integration that simultaneously enhances environmental sustainability and economic returns.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"17 ","pages":"Article 100530"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145320915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, geological storage of CO₂ in structurally complex and heterogeneous reservoirs presents a range of issues due to the geological intricacies, with implications for storage capacity estimation, CO₂ injection, migration, and even long-term containment, which pose environmental risks. Therefore, this study assesses the CO₂ storage potential of the depleted F-O Gas Field in the Bredasdorp Basin, offshore South Africa, using a robust modelling approach based on the analysis of a suite of exploration and production datasets from the field. A high degree of structural compartmentalisation with a fault-bounded anticlinal trap characterises the field. The Valanginian-age marine sandstone reservoirs exhibit low to moderate porosity and permeability. In total, a CO₂ storage capacity of 185.3 Mt was determined for the F-O gas field, which reduces to 37.1–74.1 Mt after accounting for reservoir heterogeneity and sweep efficiency. This reduction reflects the impact of the field's complex structural architecture, variable facies distribution, and petrophysical variability, which collectively limit the effective pore volume accessible for CO₂ storage. By rigorously integrating the structural architecture of the field, sedimentary processes, facies distribution, and petrophysical variability of the candidate reservoir, this study provides critical insights and strategies into the feasibility of CCS in structurally complex depleted gas fields. Significantly, these findings contribute to ongoing national CCS assessments and support South Africa’s long-term decarbonisation agenda.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"17 ","pages":"Article 100499"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145096338","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

China has pledged the dual carbon goals of peaking carbon emissions by 2030 and achieving carbon neutrality by 2060, underscoring the urgency and scale of the challenge. While Carbon Capture, Utilization, and Storage (CCUS) has emerged as a promising approach, its large-scale implementation in emission-intensive industrial clustered region faces significant infrastructural challenges. Specifically, the optimal layout of regional CCUS clusterization and CO₂ transport networks remains unclear, particularly in highly industrialized regions such as China’s Jiangsu Province, where diverse industrial sectors and varied geological formations create complex source-sink matching challenges for CCUS deployment. In this study, we developed the SPATIAL (Strategic Pipeline And Technical Integration Analysis Layout) model that enables the optimization of CCUS deployment in emission-intensive regions from an industrial cluster perspective by integrating data of emissions from major industrial sources and storage potential from geological formations. The model was applied to Jiangsu Province under high, medium, and low emission reduction target scenarios through source-sink matching. Results show significant spatial heterogeneity between emission sources and geological storage resources in Jiangsu Province. For example, southern Jiangsu, characterized by high-intensity CO₂ emission clusters, accounts for 63 % of the province’s total emissions while holding only 0.03 % of the province’s geological storage potential. The optimal layout for regional CCUS clusterization deployment under high, medium, and low emission reduction targets achieve total CO₂ storage of 1.4, 1.1, and 0.9 Gt, respectively, supported by pipeline networks of 4629, 2513, and 1433 km. These layouts demonstrate economies of scale, with unit emission reduction costs ranging from 93.84 to 179.31 CNY/t CO₂. Our findings establish the technical and economic feasibility of achieving significant emission reductions through regional CCUS clusterization deployment and address a critical gap in ignoring the hot spot phenomenon of industrial cluster. This study further emphasizes the importance of inter-regional coordination, regional geological storage resource management, and integrated infrastructure planning in realizing cost-effective CCUS clusterization implementation. This study provides policymakers with actionable insights for formulating CCUS clusterization strategies in emission-intensive industrial regions, contributing to the broader goal of regional carbon neutrality.</div></div>","PeriodicalId":9387,"journal":{"name":"Carbon Capture Science & Technology","volume":"17 ","pages":"Article 100495"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145020149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detailed fluidization behaviour was investigated using pressure drop fluctuations and discrete wavelet transformation (DWT), revealing a transition velocity (Uc) between bubbling and turbulent regimes in the FBR (under the conditions relevant to DRM), which was found to decrease with increasing temperature.

Optimal operation in the bubbling regime (800 °C, 0.1 m/s) enabled CO₂ and CH₄ conversions of 57% and 41%, respectively, with an H₂/CO ratio of 0.67. Comparative studies demonstrated that the packed bed reactor (PBR) achieved higher conversions and better H₂/CO ratios (∼0.96), attributed to its plug flow characteristics, whereas the FBR exhibited lower conversions due to gas back mixing and reactant bypassing.
