Carbon dioxide sequestration using brines has emerged as a promising technology to mitigate the adverse impacts of climate change due to its large storage capacity and favorable chemistries. However, the permanent storage of CO 2 in brines takes significantly long periods of time as the formation of carbonates is very slow. This review focuses on the four main parameters (brine composition, brine pH, system temperature, and pressure) that have been reported to have a major effect on mineral trapping of CO 2 sequestration in brines. These parameters are difficult to control for in situ underground CO 2 sequestration. However, understanding the effects of these main parameters is useful for both aboveground and underground carbonation reactions. Brine pH is the most important parameter. The precipitation of carbonate minerals is favored over a basic pH of 9.0. In order to promote the formation of carbonates, brine pH could be enhanced by using additives. System temperature has a greater effect than pressure. © 2011 Society of Chemical Industry and John Wiley & Sons, Ltd
