Abstract

Geological carbon storage involving injection of CO2 into geological formations is seen as a critical strategy to manage anthropogenic carbon emissions while society develops carbon-free energy sources. Mitigating the climatic impacts requires the stored carbon to be retained for at least 10 k.y., and there are considerable uncertainties in modeling the fate of the carbon over a time period much longer than we have observed the behavior of CO2 in geological formations. Key questions are (1) how quickly will the buoyant CO2 dissolve in formation brines (good), (2) how quickly will the CO2 brines react with silicate minerals and precipitate solid carbonate phases (good), (3) will CO2 or CO2-charged brines corrode cap-rocks and escape upward (bad), and (4) will CO2 penetrate up fault zones (bad)?
