System and method for carbon dioxide capture and sequestration

A system for removing carbon dioxide from carbon dioxide laden air, the system comprising:

• a carbon dioxide capture structure comprising a porous solid mass having a high surface area and an amine sorbent distributed along the surface area of the porous solid mass and that is capable of reversibly adsorbing, or binding, to carbon dioxide,
• an air conduit, open at one end to the atmosphere and at a second end to the capture structure, for bringing a flow of carbon dioxide-laden ambient air to and through the carbon dioxide capture structure at a first location,
• a sealable regeneration chamber capable of containing the capture structure at a second location;
• carriage means for moving the capture structure between the first and the second locations;
• a source of process heat steam for providing steam at a temperature of not greater than 120° C.;
• a hot fluid conduit connected to the source of process heat steam and to the sealable regeneration chamber for directing such process heat steam at the carbon dioxide-loaded sorbent on the capture structure in the regeneration chamber to strip carbon dioxide from the sorbent;
• and
• a fluid conduit for carrying the separated carbon dioxide away from the regeneration chamber.
