Ex situ CO2 Mineralization Using Reactive Species

摘要

While geologic sequestration method may be used to store large volumes of CO2, it involves two distinct steps, i.e., capture and storage, with the former being a more costly step. Also, finding suitable storage sites, pumping supercritical CO2, safekeeping it underground, and handling of saline water discharges could impede its deployment. CO2 mineralization, on the other hand, can be a single-step process and the product can be stored permanently. In some cases, the product can be utilized as construction materials which will defray the cost for CO mineralization.
