## Abstract

Methods of producing solid CO2 sequestering carbonate materials are provided. Aspects of the methods include introducing a divalent cation source into a flowing aqueous liquid (e.g., a bicarbonate rich product containing liquid) under conditions sufficient such that a non-slurry solid phase CO2 sequestering carbonate material is produced. Also provided are systems configured for carrying out the methods.
