Abstract

A method and a system capable of removing carbon dioxide directly from ambient air, and obtaining relatively pure CO₂. The method comprises the steps of generating usable and process heat from a primary production process; applying the process heat from said primary process to co-generate substantially saturated steam, alternately repeatedly exposing a sorbent to removal and to capture regeneration system phases, wherein said sorbent is alternately exposed to a flow of ambient air during said removal phase, to sorb, and therefore remove, carbon dioxide from said ambient air, and to a flow of the process steam during the regeneration and capture phase, to remove the sorbed carbon dioxide, thus regenerating such sorbent, and capturing in relatively pure form the removed carbon dioxide. The sorbent can be carried on a porous thin flexible sheet constantly in motion between the removal location and the regeneration location.
