摘要： Apparatus, systems, and methods store energy by liquefying a gas such as air, for example, and then recover the energy by regasifying the liquid and combusting or otherwise reacting the gas with a fuel to drive a heat engine. The process of liquefying the gas may be powered with electric power from the grid, for example, and the heat engine may be used to generate electricity. Hence, in effect these apparatus, systems, and methods may provide for storing electric power from the grid and then subsequently delivering it back to the grid.

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 network 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 network output. Systems of the present disclosure can employ solar heating for improved storage efficiency.

摘要： A stabilization system for a rotating load, such as a flywheel, includes a mechanical bearing to continuously support a shaft of the rotating load so as to hold the shaft at a substantially fixed axis of rotation. A magnetic stabilization assembly includes a plurality of electromagnets arranged around the shaft. Control circuitry for controls a resultant magnetic field generated by the electromagnets such that the magnetic field acts on a ferromagnetic element of the shaft to reduce imbalance forces acting on the shaft.

摘要： A homopolar DC electromagnetic transmission (HET) and an application system thereof are provided. The HET includes two rotors, a stator, an external auxiliary system and an adjustment control system. Each of the rotors has one or more axisymmetric rotor magnetic conductors, and the stator has one or more direct current magnet exciting coils wound around an axis of a rotation shaft. A main magnetic circuit is guided to be a closed ring. The HET includes at least two main magnetic circuits. The HET includes a closed main current loop. The loop is connected with all the rotor magnetic conductors, a rotor electric conductor, a dynamic/static circuit connecting medium, stator conductors and stator magnetic conductors in series or in series and parallel. A direction of main current on the rotor magnetic conductors is perpendicular to a direction of magnetic flux (ϕ) on meridian plane.
