Modern thermal power plants based on classical thermodynamic power cycles suffer from an upper bound efficiency restriction imposed by the Carnot principle. This disclosure teaches how to break away from the classical thermodynamics paradigm in configuring a thermal power plant so that its efficiency will not be restricted by the Carnot principle. The power generation system described herein makes a path for the next generation of low-to-moderate temperature thermal power plants to run at significantly higher efficiencies powered by renewable energy. This disclosure also reveals novel high-performance power schemes with integrated fuel cell technology, driven by a variety of fuels such as hydrogen, ammonia, syngas, methane and natural gas, leading toward low-to-zero emission power generation for the future.

The invention relates to a system and process for electricity generation using steam production by hydrogen combustion, and more particularly to a Rankine Cycle system and process for the generation of electricity using a primary pure hydrogen fuel source for the generation of steam in the boiler system. The Rankine Cycle system and process may also use one or more secondary fuel sources in combination with the primary hydrogen fuel source to supplement the primary pure hydrogen fuel if necessary. Additionally, the inventive system and process can use a flame temperature reducing fluid for lowering bulk flame temperature of a burner in the boiler system to increase equipment life and decrease equipment failure. The inventive Rankine Cycle system and process reduce emissions of carbon dioxide, nitrogen oxides, and other greenhouse gases into the atmosphere, and reduce bulk flame temperatures to increase equipment life and decrease equipment failure.

This is a zero emissions power generation boiler that can be used to drive a wide range of steam turbines, from 20 MW up to 1200 MW, creating dry steam pressure ranging from 1000 psi up to 4500 psi. It creates steam by burning liquid hydrogen with liquid oxygen, completely eliminating the emission of greenhouse gases, lethal poisons, and every form of pollutant. It employs high-pressure cryogenic fuel pumps, a water cooling system, an electronic sparking system, a double-wall cylindrical boiler with a hemispherical top, and a control system that employs electronic sensors, actuators, signal conditions, microprocessors, digital interfaces, and mechanical back-up systems. It can be used in new power plants or as a replacement for current boilers in existing power plants. It has the option of working as part of a combined cycle system and can employ steam reheat systems.
