Surface dissolution: Minimizing groundwater impact and leakage risk simultaneously

Any substantive campaign to mitigate greenhouse gas emissions must involve sequestration of CO2 in geologic formations. For stakeholders to accept this technology, the risk of leakage from the storage formation must be balanced against the economics of capture and injection. The standard approach to geologic sequestration assumes that CO2 will be injected as a bulk phase into a saline aquifer. The primary driver for leakage in this approach is...
