“…Dewar et al [39] showed a demonstration of integrating a multi-phase leakage model, PLUME, into a high-resolution hydrodynamic model linked to a carbonate system for a CO 2 analysis in the North Sea region. The system was constructed on the unstructured-grid finite-volume community ocean model (FVCOM) to capture local and regional hydrodynamics [40], and the nested domains ranged from 2.5 km at the boundaries to 0.5-1.0 m at the release sites.…”

“…Different experiments, QICS and STEMM-CCS, were simulated to explore the fate of CO 2 bubbles and dissolved solutions. Specific findings included the accumulation of CO 2 solutions at release locations during low current speeds, the prevention of significant vertical movements due to stratification or well-mixed conditions, and limited horizontal transport beyond ~100 m from the release site [39].…”

“…The results from Dewar et al [39] showed the importance of considering local dynamics for predicting the impacts of CO 2 leakages in marine environments, showcasing the capabilities of the integrated modeling system in capturing these dynamics at different scales. Their findings highlighted the significant impact of water currents and resolution on local effects, revealing momentary spikes in pCO 2 and pH reductions due to tidal oscillation.…”

The exponential increase in greenhouse gas emissions necessitates urgent measures to mitigate climate change impacts. Carbon capture and storage (CCS) has emerged as a promising solution, capturing CO2 from industrial processes and storing it underground. However, CCS implementation poses risks that demand sophisticated modeling. This review focuses on the numerical modeling of CO2 plume dispersion from reservoir leaks during offshore CCS projects, including near- and far-field modeling and the comparison between Lagrangian and Eulerian modeling in particular. Near-field modeling examines CO2 behavior in jet plume, considering depth-related changes. Far-field modeling, employing Eulerian and Lagrangian methods, evaluates dispersion in marine environments. Case studies illustrate the complexity and uniqueness of CO2 dispersion events. The Lagrangian approach emphasizes gas bubble tracking, while the Eulerian approach employs fixed grid systems for detailed hydrodynamic modeling. Both approaches contribute valuable insights, with Eulerian models excelling in site-specific complexities and Lagrangian models offering computational efficiency. A hybrid approach may offer a comprehensive understanding of CO2 dispersion.

“…Migration of CO 2 within the sediments and the impact of the CO 2 release on the sediments is investigated using chemical, geophysical and hydromechanical methods (de Beer et al, 2021;Falcon-Suarez et al, 2021;Lichtschlag et al, 2021a;Robinson et al, 2021;Roche et al, 2021), electromagnetic techniques are applied to the investigation of fluid flow pathways in sediments (Gehrmann et al, 2021), while the feasibility of seismic techniques for detection and monitoring of a CO 2 leak is assessed (Waage et al, 2021). Modelling papers cover environmental monitoring and assessment including both detection, quantification, and impacts of a CO 2 leak in the water column (Blackford et al, 2020;Cazenave et al, 2021;Dewar et al, 2021;Omar et al, 2021;Yakushev et al, 2021), and migration in the sediments (Saleem et al, 2021). Finally, there is an assessment of the knowledge gained from STEMM-CCS and two other related projects (Dean et al, 2020) and a study of stakeholder views on North Sea CCS (Gonzalez et al, 2021).…”
