The Verdox SystemElectricEﬃcient

Requires only electricity as input into
the capture mechanism - no need forheat or water.

Uses up to 70% less energy by
avoiding energy losses fromheating & cooling.

Reliable

Versatile

Requires no moving parts in thecapture mechanism that can cause
downtime.

Leverages modular approach tocapture CO₂ at any scale andconcentration.

The Electrochemical CellCapturing electrodeCaptures CO2 during charging from incoming feed and holds on to it
Release CO2 during discharge as pure gas productHas redox material with binary aﬃnity to CO2

Does not interact with CO2Balances the charge of capturing electrode
Matches the rate of charging (capture) of the capturing electrode
