Patent ID: 7634915

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 said first combustion chamber; and a first turbine configured to receive a first discharge from said first combustion chamber and generate a first exhaust and electrical energy; a second gas turbine system comprising: a second combustion chamber configured to combust a second fuel stream to generate a second discharge, wherein said first compressor of said first gas turbine system is configured to supply a second portion of compressed oxidant to said second combustion chamber; and a second turbine configured to receive said second discharge from said second combustion chamber to generate a second exhaust and electrical energy; and a second compressor configured to receive said second exhaust comprising carbon dioxide and to discharge a recycle stream to said second combustion chamber and a split stream to a separator system adapted to recover carbon dioxide; and a hydrogen generation system configured to receive a third fuel and steam to generate said first fuel and a third exhaust gas, wherein said third exhaust gas is introduced into said second combustion chamber, wherein said hydrogen generation system comprises: a steam reforming zone configured to reform fossil-based fuels to generate a reformate comprising hydrogen; at least one heat exchanger; and a hydrogen separator to generate an off gas stream, wherein said off gas stream is combusted in a combustor along with a third portion of compressed oxidant from said first compressor to supply heat to said steam reforming zone and generate said third exhaust gas.
