CO2BOL-NG – Pacific Northwest National Laboratory
CO2BOLs are organic liquids that can absorb combustion products such as CO2 or SO2. In the case of CO2, this provides for carbon capture; for SO2, a reduction in the major cause of acid rain. CO2BOLs can be regenerated under mild conditions, with the captured gas being recovered for use or sequestration. The system has been dubbed as the "Swiss Army Knife" of chemical solvents because of the ability to tailor the specific chemistry to the specific gas separation application.
