Patent ID: 7266940

Claim:
A power generation system comprising: a first gas turbine system comprising: a first combustion chamber configured to combust a first fuel stream of primarily hydrogen that is substantially free of carbon-based fuels; a first compressor configured to supply a first portion of compressed oxidant to the first combustion chamber; and a first turbine configured to receive a first discharge from the first combustion chamber and generate a first exhaust and electrical energy; and a second gas turbine system comprising: a second combustion chamber configured to combust a second fuel stream to generate a second discharge, wherein the first compressor of the first gas turbine system is configured to supply a second portion of compressed oxidant to the second combustion chamber; and a second turbine configured to receive the second discharge from the second combustion chamber to generate a second exhaust and electrical energy; and a second compressor configured to receive the second discharge comprising carbon dioxide and to discharge a recycle stream to the second combustion chamber and a split stream to a separator system adapted to recover carbon dioxide.
