Carbon dioxide is formed in all processes utilizing fossil fuels. Controlling the emissions of CO 2 from a number of processes by forming CO 2 hydrates (clathrates), may be an effective approach for both absorbing CO 2 from multicomponent gas streams (Flue gases, Anaerobic digester gases, etc.) and sequestering CO 2 in the deep oceans. Further, ocean marine farms may be an effective process for extracting CO 2 from the atmosphere and forming both valuable products and rejecting excess CO 2 , in the form of clathrates, to the deep ocean. Preliminary engineering analyses indicates that clathrate formation for controlling both conventional fossil fuel gaseous CO 2 emissions and those associated with marine farm anaerobic digester gases may provide a meaningful control strategy for CO 2 .
