Factors affecting compressed carbon dioxide energy storage system in deep aquifers
Compressed air energy storage (CAES) technology is a vital solution for managing fluctuations in renewable energy, but conventional systems face challenges like low energy density and geographical constraints. This study explores an innovative approach utilizing deep aquifer compressed carbon dioxide (CO2) energy storage to overcome these limitations. To identify the factors affecting compressed CO2 energy storage system in deep aquifers, numerical simulations using T2well/ECO2N investigate hydrodynamic and thermodynamic behaviors, focusing on the impact of aquifer properties (depth, thickness, porosity, and permeability) and operational parameters (wellbore penetration depth through the aquifer and energy storage scale) on system performance. The findings reveal notable pressure variations in both the wellbore and aquifer during system operation and the injected supercritical CO2, input by geothermal energy from the surrounding formations, contributes to high energy storage efficiency across the entire system. The impact factor analysis suggests medium aquifer depth and permeability, a storage space with high porosity, increased aquifer thickness, greater wellbore penetration depth, and larger energy storage scales contribute to the safe and efficient operation of the system.
期刊介绍：
Engineering geology is defined in the statutes of the IAEG as the science devoted to the investigation, study and solution of engineering and environmental problems which may arise as the result of the interaction between geology and the works or activities of man, as well as of the prediction of and development of measures for the prevention or remediation of geological hazards. Engineering geology embraces:
• the applications/implications of the geomorphology, structural geology, and hydrogeological conditions of geological formations;
• the characterisation of the mineralogical, physico-geomechanical, chemical and hydraulic properties of all earth materials involved in construction, resource recovery and environmental change;
• the assessment of the mechanical and hydrological behaviour of soil and rock masses;
• the prediction of changes to the above properties with time;
• the determination of the parameters to be considered in the stability analysis of engineering works and earth masses.
