Geological storage of carbon dioxide (CO2) is one of the options envisaged for mitigating the environmental consequences of anthropogenic CO2 increases in the atmosphere. The general principle is to capture carbon dioxide at the exhaust of power plants and then to inject the compressed fluid into deep geological formations. Before implementation over large scales, it is necessary to assess the efficiency of the process and its environmental consequences. The goal of this paper is to discuss some environmental mineralogy research perspectives raised by CO2 geological storage.
