High‐efficiency power production from coal with carbon capture

Abstract A zero‐emissions power plant with high efficiency is presented. Syngas, produced by the gasification of coal, is shifted to produce H 2 which in turn fuels stacks of solid oxide fuel cells. Because the fuel cells maintain separate anode and cathode streams, air can be used as the oxygen source without diluting the fuel exhaust with nitrogen. This enables recovery of CO 2 from the exhaust with a very small energy penalty. As a result, …
