An experimental investigation on the CO2 storage capacity of the composite confining system

•Sand tank experiments and modified invasion percolation simulations were conducted.•Simulation results match experimental results reasonably well despite discrepancies.•Curved barriers can greatly enhance CO2 trapping while gradations do not.•Longer barriers retain more CO2 regardless of barrier to...
