摘要： A method for operating a closed loop regenerative thermodynamic power generation cycle system is presented. The method includes supplying a high-temperature working fluid stream at a first pressure P1 to an expander, and extracting a partially expanded high temperature working fluid stream from the expander at a second pressure P2. Each of the first pressure P1 and the second pressure P2, are higher than a critical pressure of the working fluid; and the second pressure P2 is lower than P1. The method further includes regeneratively supplying the extracted high temperature working fluid stream at the second pressure P2 to a low temperature working fluid stream at the first pressure P1. A closed loop regenerative thermodynamic power generation cycle system is also presented.

摘要： The present invention describes a novel integration between wind and solar thermal renewable energy technologies. An existing wind turbine consisting of a hub and blades is operated by the power generated from a waterless solar thermal system (using high pressure, high temperature air) during periods of low wind availability. The solar thermal system consist of a heliostat field, solar air receiver panels, a thermal energy storage tank and a Pelton wheel assembly system for converting thermal energy of air into kinetic energy of the power shaft of the wind turbine. The thermal energy converting system consists of a plurality of supersonic air nozzles acting as stator, producing supersonic air jets to interact with a rotating Pelton wheel. A thermal storage system provides means for energy dispatchability. The proposed integrated system is capable of generating a stable renewable energy with minimum intermittency.

摘要： The invention relates to systems and methods for rapidly and isothermally expanding and compressing gas in energy storage and recovery systems that use open-air hydraulic-pneumatic cylinder assemblies, such as an accumulator and an intensifier in communication with a high-pressure gas storage reservoir on a gas-side of the circuits and a combination fluid motor/pump, coupled to a combination electric generator/motor on the fluid side of the circuits. The systems use heat transfer subsystems in communication with at least one of the cylinder assemblies or reservoir to thermally condition the gas being expanded or compressed.

摘要： A method for alternate storage and outputting of the thermal energy which is obtained in the primary circuit of a solar-thermal power station, using a heat carrier medium, which can be partially fed between a plurality of storage tanks, in each case flowing through a heat transmission apparatus which is operatively connected to the primary circuit and/or to the steam/water circuit, which heat carrier medium can be heated to a higher temperature or can be cooled to a lower temperature, the aim is to provide a solution which makes it possible, with a storage capacity which is the same as that of installations known from the prior art, to avoid the disadvantages of the prior art, in particular with a smaller space requirement and occupying a smaller installation area. This is achieved in that at least one of the plurality of storage tanks is alternately used for storage of a respectively partially fed volume of the heat carrier medium in the state of its higher temperature and for storage of a respectively partially fed volume of the heat carrier medium in the state of its lower temperature.

摘要： Techniques for generating power are provided. Such techniques involve a thermodynamic system including a housing, a turbine positioned in a turbine cavity of the housing, a compressor positioned in a compressor cavity of the housing, and an alternator positioned in a rotor cavity between the turbine and compressor cavities. The compressor has a high-pressure face facing an inlet of the compressor cavity and a low-pressure face on an opposite side thereof. The alternator has a rotor shaft operatively connected to the turbine and compressor, and is supported in the housing by bearings. Ridges extending from the low-pressure face of the compressor may be provided for balancing thrust across the compressor. Seals may be positioned about the alternator for selectively leaking fluid into the rotor cavity to reduce the temperature therein.
