Assessing the Potential of Mineral Carbonation with Industrial Alkalinity Sources in the US

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. (C) 2013 The Authors. Published by Elsevier Ltd.
