1. A method of sequestering CO2 from a gaseous source of CO2, the method comprising:
(a) contacting an aqueous ammonia capture liquid with a gaseous source of CO2 under conditions sufficient to produce a CO2 sequestering carbonate and an aqueous ammonium salt; and
(b) combining the aqueous ammonium salt with a geomass to produce a regenerated aqueous ammonia capture liquid;
to sequester CO2 from the gaseous source of CO2,
wherein the method does not comprise purification of the regenerated aqueous ammonia capture liquid.
