摘要： Systems and methods relating to variable pressure turbines are disclosed. A power generation system may include a closed cycle system configured to generate power, a combustor, and a control system. The closed cycle system may include a working fluid circulating in a closed cycle path. The combustor may provide thermal energy to the working fluid. Further, the control system may be configured to determine to increase an amount of power generated by the closed cycle system, and in response to the determination to increase the amount of power generated by the closed cycle system, cause an increase in pressure of the working fluid in the closed cycle path.

摘要： Electrical/mechanical power is derived from oxycombustion of hydrocarbons, preferably LNG, in a first of two nested cycles each operating on a Brayton cycle to provide a source of power, without mixing of working fluids between the two cycles. Each cycle employs CO2 as a working fluid, the first cycle operating under low pressure conditions in which CO2 is sub-critical, and the other cycle operating under higher pressure conditions in which CO2 is supercritical. The first cycle serves as a source of heat for the second cycle by gas/gas heat exchange which cools the products of combustion and circulating working fluid in the first cycle and heats working fluid in the second cycle.

摘要： An energy conversion system is disclosed with a converging-diverging duct, a first turbine, a compressor, a second turbine, and a return duct. The first converging-diverging duct is configured to receive a working fluid. The first turbine is configured to increase or decrease kinetic energy of the working fluid entering the first converging-diverging duct. The compressor device is configured to receive the working fluid after exiting the converging-diverging duct. The second turbine is in a flow path of the working fluid between the first converging-diverging duct and the compressor device. The second turbine is configured to decrease or increase kinetic energy of the working fluid entering the compressor device. The first and second turbines impart opposite changes to kinetic energy in the working fluid. The return duct is configured to return the working fluid to the first converging-diverging duct after passing through the compressor device.

摘要： The present disclosure provides pumped thermal energy storage systems that can be used to store electrical energy. A pumped thermal energy storage system of the present disclosure can store energy by operating as a heat pump or refrigerator, whereby net work input can be used to transfer heat from the cold side to the hot side. A working fluid of the system is capable of efficient heat exchange with heat storage fluids on a hot side of the system and on a cold side of the system. The system can extract energy by operating as a heat engine transferring heat from the hot side to the cold side, which can result in net work output. Systems of the present disclosure can employ solar heating for improved storage efficiency.
