Direct Air Capture

Technology Owner: Carbon Engineering

About: Carbon Engineering’s direct air capture process separates CO2 from atmospheric air in a four-step process. First, atmospheric air is run over an air contactor using a strong hydroxide solution that captures CO2 and turns it into carbonate. Second, the carbonate is run through a pellet-reactor to refine the carbonate into small calcium carbonate pellets. Third, the pellets are heated up, releasing a pure stream of CO2 and leaving behind calcium oxide. Finally, the calcium oxide is rehydrated with water to regenerate the hydroxide solution, closing the chemical loop.

Application: Atmospheric Capture
