1. A method of sequestering CO2 from a gaseous source of CO2, the method comprising:
a) contacting an aqueous capture ammonia with a gaseous source of CO2 in a combined capture and alkali enrichment reactor under conditions sufficient to produce an aqueous ammonium carbonate;
b) combining a cation source and the aqueous ammonium carbonate under conditions sufficient to produce a CO2 sequestering carbonate and an aqueous ammonium salt; and
c) regenerating aqueous capture ammonia from the aqueous ammonium salt;
to sequester CO2 from the gaseous source of CO2.
