Abstract: An aircraft propulsion system includes a core engine and a bottoming cycle where a working fluid is circulated within a closed circuit. A first heat exchanger is used to transfer heat from a portion of thermal energy from the exhaust gas flow to working fluid of the bottoming cycle. A fuel/working fluid heat exchanger provides the cryogenic fuel to cool the working fluid exhausted from a bottoming turbine and before a bottoming compressor.

Abstract: Methods for the beneficial use of waste heat in commercial or industrial operations are provided. The method includes generating power by combusting hydrogen in a gas turbine or through an electrochemical process using hydrogen in a fuel cell, recovering waste heat from the gas turbine exhaust in a heat recovery steam generator, and utilizing the waste heat in one or more commercial or industrial operations. The hydrogen has a carbon intensity preferably less than about 1.0 kg CO2e/kg H2 and may be produced by reforming a hydrocarbon feedstock or by electrolysis of water, wherein at least some of the required energy for the hydrogen production process is provided by a biomass power plant with carbon capture.

Abstract: The present disclosure relates to systems and methods useful for power production. In particular, a power production cycle utilizing CO2 as a working fluid may be configured for simultaneous hydrogen production. Beneficially, substantially all carbon arising from combustion in power production and hydrogen production is captured in the form of carbon dioxide. Further, produced hydrogen (optionally mixed with nitrogen received from an air separation unit) can be input as fuel in a gas turbine combined cycle unit for additional power production therein without any atmospheric CO2 discharge.
