The first step in minimizing risk of a high-volume CO2 release from a natural deposit 2 178, 183 Estimation and quantitative predictions of geological CO2 storage security suggest geological storage is a secure, resilient and a feasible option for reducing global climate change even when applying worst-case values for each scenario. 184 CO2 becomes safer and more secure the longer it stays in the ground due to a range of physical processes, with mineralization being the ultimate goal as trapping of CO2 becomes permanent.
