1. An engine system comprising:
an oxygen capture system comprising at least one adsorbent material;
an internal combustion engine fluidly coupled to the oxygen capture system;
an exhaust processing system fluidly coupled to the internal combustion engine, the exhaust processing system comprising a catalytic system, at least one cooler, and at least one gas/liquid separator;
a carbon capture system fluidly coupled to the exhaust processing system and the internal combustion engine, the carbon capture system comprising a carbon dioxide condenser and a carbon dioxide storage;
a compressor fluidly coupled to the at least one gas/liquid separator and receiving processed exhaust from the at least one gas/liquid separator; and
a second cooler fluidly coupled to the compressor and receiving the processed exhaust from the compressor;
wherein the carbon dioxide condenser is fluidly coupled to the second cooler and receives the processed exhaust from the second cooler;
wherein the carbon dioxide condenser produces liquid or partial liquid carbon dioxide from the processed exhaust; and
wherein the carbon dioxide storage is fluidly coupled to the carbon dioxide condenser and receives the liquid or partial liquid carbon dioxide from the carbon dioxide storage and stores the liquid or partial liquid carbon dioxide.
