Overview about KSCO2Tech
KSCO2Tech technology is based on simple chemical reactions using cheap and available chemicals such as NaOH and CaCl2. Eventually, the process technology is easily constructed at a low cost and the system fits the sustainable development goals (SDGs).
Main Functions
Both ambient and exhaust CO2 can be captured with novel methods and easily converted into limestone, CaCO3, which is useful, harmless, and stable. Other technologies such as geo-sequestration by injecting CO2 into underground are not practical and costly, which could be possible in future. KSCO2Tech offers byproducts, such as H2 and Cl2, which are produced through electrolysis of NaCl.
Furthermore, HCl which is produced in the electrolysis can convert Na2CO3 or CaCO3 to CO2 without thermal energy.

Performance
CO2 can be captured from the ambient air or from flue gas via several technologies, including absorption, adsorption and gas membrane separation. However, these technologies have been developed at the experimental levels in the laboratory. Although adsorption with amines is currently the dominant technology, the thermal addition which induces chemical decomposition of the amines is necessary to release CO2 from the CO2-amine complex. This thermal addition produces CO2. Eventually, this amine technology has not been used worldwide.
