Abstract: A gas turbine combined-cycle power plant can comprise a gas turbine engine, a heat recovery steam generator, a steam turbine, a fuel regasification system and a Rankine Cycle system. The gas turbine engine can comprise a compressor for generating compressed air, a combustor that can receive a fuel and the compressed air to produce combustion gas, and a turbine for receiving the combustion gas and generating exhaust gas. The heat recovery steam generator is configured to generate steam from water utilizing the exhaust gas. The steam turbine is configured to produce power from steam from the heat recovery steam generator. The fuel regasification system is configured to convert the fuel from a liquid to a gas before entering the combustor. The Organic Rankine Cycle system is configured to cool compressed air extracted from the compressor to cool the gas turbine engine, and heat liquid fuel entering the fuel regasification system.

Abstract: A power plant comprises a combustor for combusting first and second constituents to generate a gas stream, a turbine for rotation by the gas stream, a compressor to receive a first portion of the gas stream and provide compressed gas to the combustor, a recompressor configured to receive a second portion of the gas stream and provide compressed gas to the combustor, a generator to be driven by the turbine, and a methane reforming reactor configured to dry reform methane to provide the first constituent. A method of operating a power plant comprises operating a supercritical CO2 power cycle to turn a turbine, driving a generator with the turbine, extracting CO2 byproduct from the power cycle, reacting fuel and CO2 to produce a synthesis gas in a dry reforming of methane reactor, and mixing the synthesis gas with oxygen to execute a combustion process for the power cycle.
