Continuous Electrochemical Gas Separation

Completed Technology Project

Project Description

CO2 is transported from a low concentration (cathode side) to a high concentration (anode side) by reaction with an electrochemically active carrier. CO2 is bound to a reduced form of the carrier, and is released when the carrier is oxidized.
State-of-the-art carbon dioxide removal technology is heavy and requires considerable power. This novel approach is based on an electrochemical membrane technology that incorporates ionic liquids. It uses only electricity to drive the separation, with no moving parts or pressure drops and CO2 can be collected for oxygen recovery. More »
