Abstract

Methods of sequestering carbon dioxide (CO) are provided. Aspects of the methods include contacting an aqueous capture ammonia with a gaseous source of COunder conditions sufficient to produce an aqueous ammonium carbonate. The aqueous ammonium carbonate is then combined with a cation source under conditions sufficient to produce a solid COsequestering carbonate and an aqueous ammonium salt. The aqueous capture ammonia is then regenerated from the from the aqueous ammonium salt. Also provided are systems configured for carrying out the methods.
