Aqueous mineral carbonation has been studied at the Albany Research Center as a potential option for CO2 sequestration. The research has included fundamental studies, resource evaluation, and process development. Studies have focused on the reaction of Ca-, Fe-, and Mg-silicate minerals with gaseous CO2 to form geologically stable, naturally occurring solid carbonate minerals. Process development has progressed in parallel with an economic evaluation, with an initial overall cost estimate of ~$69/ton CO2. Improved mineral pretreatment and reactor design indicate that costs could be reduced. However, the scale of ex-situ operations, requiring ~55 kt mineral/day to carbonate 100% of the CO2 emissions from a 1 GW coal-fired power plant, may favor an in-situ methodology. Laboratory studies of in-situ mineral carbonation show promise.
