A process of producing a feed from a solid oxide electrolysis cell. A first portion of the flue gas produced from a combustion process is directed to the anode side of the solid oxide electrolysis cell. The feed and a second portion of the flue gas are then mixed to produce an enhanced feed. The enhanced feed is then mixed with fuel and combusted in the combustion process to produce flue gas. The flue gas comprises greater than 50 wt % CO.sub.2 and less than 1 wt % N.sub.2.
