WebThe various CO 2 storage mechanisms have different operating time frames, among which the hydrodynamic and adsorption trapping take effect immediately after the CO 2 injection, while the residual gas, dissolution and particularly the mineral trapping mechanisms are a slow process, and can occur over a time scale of centuries to millennia. WebThe efficiency of CO 2 geological storage is determined by the structure of the sedimentary basins, which have an intricate plumbing system defined by the location of high and low permeability strata that control the flow of fluids throughout the basin and define ‘hydrogeological’ traps.
