<p>A closed loop energy conversion system (10) for converting a non-fossil fuel energy source to a fossil fuel without generating air polluting emissions when the fossil fuel is combusted to provide energy to an external source. The apparatus employed in this process includes a dissociation unit (12) for dissociating water into hydrogen gas and oxygen gas and separating hydrogen gas from oxygen gas. An energy source (14) provides energy to the dissociation unit. Oxygen gas and hydrocarbon gas react in a hydrocarbon combustion unit (40) to form a combustion product. A first heat exchanger (26) cools the combustion product and condenses water vapor. A carbon dioxide separator (46) separates carbon dioxide gas from water condensed in the first heat exchanger. Carbon dioxide gas reacts with hydrogen gas in a hydrocarbon synthesis reactor (24) to form a mixture comprising hydrocarbon gas and water vapor. A hydrocarbon separator (30) separates hydrocarbon gas from water condensed in the second heat exchanger.</p> |
