At its core, Skyonic’s SkyCycle™ carbon capture technology uses waste-heat from the source — a CO2 emitting plant — to mineralize CO2 emissions from that same plant. SkyCycle™ uses a synthetic base to capture the mildly acidic CO2, and mineralizes it as a solid carbonate. The primary, profitable product from the proposed Canadian SkyCycle™ Plant is hydrochloric acid (HCl).

SkyCycle™ uses a synthetic base to capture the mildly acidic CO2, which is formed from the thermal decomposition of a hydrated salt. During the CO2 absorption process, a second salt is added to produce a product carbonate and the previously decomposed salt is regenerated as a chloride. The thermal decomposition yields HCl gas, and the resulting hydrochloric acid regenerates the second salt by reacting with mineral silicates.
