Carbon Atlantis

The IPCC estimates that 6 GtCO2 of carbon removal is necessary by 2050 to achieve net zero emissions. and monumental efforts will be necessary to capture 6B additional, permanent tons annually. DAC will make an important contribution to this goal, but must become more energy- and cost-effective.

Carbon Atlantis' novel DAC technology is based on its electrochemical cell for energy-efficient pH-swing. This continuous, closed-loop system comprises an air contactor and an electrochemical backend. Fans mobilize atmospheric air, exposing a basified liquid solvent to the air, capturing the CO2 as bicarbonates. The backend liberates the CO2 molecules from the solvent at low pH regimes (pH-swing), before regenerating the solvent in stacked electrochemical cells by applying an electrical current.
