Abstract

A continuous COcapture system, method, and device are disclosed. The device includes a COpump membrane including a moisture-swing material, and a cavity having a first fluid. The COpump membrane separates the first fluid from a second fluid, the fluids creating a water concentration gradient across the membrane and transport of water through the membrane. The water concentration gradient creates a carbon concentration gradient across the membrane that decreases moving from outside the cavity to inside the cavity. As water is continuously transported from the first fluid to the second fluid through the COpump membrane because of the water concentration gradient, carbon dioxide is continuously captured from the second fluid by the moisture-swing material of the COpump membrane and continuously pumped along the carbon concentration gradient across the COpump membrane and into the first fluid within the cavity.
