Assessing the Potential of Mineral Carbonation with Industrial Alkalinity Sources in the U.S

Abstract

The availability of industrial alkalinity sources is investigated to determine their potential for the mineral carbonation of CO₂ from point-source emissions in the United States. The available aggregate markets are investigated as potential sinks for the mineralized CO₂ products. Additionally, a life-cycle assessment of aqueous mineral carbonation suggests that a variety of alkalinity sources and process configurations are capable of net CO₂ reductions. The CO₂ storage potential of mineral carbonation was estimated using the life-cycle assessment results and alkalinity source availability.
