Relative performance of hydraulic, hydro-mechanical and thermo-hydro-mechanical models on the geological sequestration of CO2 in deep saline aquifers

Key Points

• Geological sequestration of CO2 is influenced by the type of model used, particularly hydro-mechanical interactions.
• Hydraulic models showed variable performance compared to thermo-hydro-mechanical models, impacting CO2 retention.
• Analysis of model effectiveness across various conditions indicates the need for improved simulation methods.
• Further evaluation of these models is necessary to enhance our understanding of CO2 behavior in geological environments.
