Abstract: Energy storage and retrieval systems are disclosed, along with methods of storing and retrieving the energy. The systems include an energy storage system and a trilateral cycle. The energy storage system includes low- and high-temperature energy storage tanks storing one or more energy storage media that exchange heat with a working fluid in both a gradient heat exchanger and a substantially isothermal heat exchanger in the trilateral cycle. Pressure changing devices transport the energy storage medium/media between the storage tanks and through the heat exchangers. The working fluid rejects heat to the energy storage medium and drives a turbine when the system is charging, and the energy storage medium rejects heat to the working fluid when the system is discharging. In some embodiments, the energy storage medium drives a second turbine when the system is discharging.

Abstract: Systems and methods are provided for pumping hydrogen within an electrochemical cell system. In one example, a liquid driven hydrogen pump includes an impeller positioned within a flow path of a gas, and a turbine coupled to the impeller by a shaft and positioned within a flow path of a liquid. A flow of the liquid is driven by a liquid pump based on operation of the electrochemical cell system and the flow of the liquid across the turbine drives rotation of the impeller and an increase in a flow of the gas.

Abstract: An energy recovery system in a seawater desalination plant uses a reverse-osmosis membrane method for removing salinity from seawater. The system is configured to supply high-pressure water produced by pressurizing raw water with a high-pressure pump to a reverse-osmosis membrane cartridge, and to supply concentrated water discharged from the cartridge to an isobaric energy recovery device to recover pressure energy of the concentrated water whereby part of the raw water supplied to the isobaric energy recovery device is pressurized, and then to allow the pressurized raw water to merge into the high-pressure water pressurized by the high-pressure pump. The system includes a booster pump for boosting a pressure of the concentrated water discharged from the cartridge, and an energy recovery turbine for recovering energy by using the pressure head difference between the pressurized raw water from the isobaric energy recovery device and the high-pressure water discharged from the pump.

Abstract: The invention relates to a device and a method for separating dirt particles from the working medium of a turbine (10). The turbine (10) comprises at least one rotor (11) which is arranged in a housing (17). A swirl generator (20) is provided that sets the working medium and the dirt particles in a spiral-shaped rotational movement along a principal axis (22) by means of the geometry of the swirl generator (20) and thereby separates the dirt particles from the working medium. The swirl generator (20) is designed in such a way that the working medium experiences a reversal of the speed component parallel to the principal axis (22) within the swirl generator (20).
