    摘要： Embodiments relate generally to energy storage systems, and in particular to energy storage systems using compressed gas as an energy storage medium. In various embodiments, a compressed gas storage system may include a plurality of stages to convert energy into compressed gas for storage, and then to recover that stored energy by gas expansion. In certain embodiments, a stage may comprise a reversible compressor/expander having a reciprocating piston. Pump designs for introducing liquid for heat exchange with the gas, are described. Gas flow valves featuring shroud and/or curtain portions, are also described.

    摘要： An expansion system utilizes external combustion of its residual warm exhaust air, in order to heat incoming compressed air. The heat of this external combustion is communicated to the incoming compressed air through a heat exchanger. The expansion system may be incorporated into an energy storage device also featuring a compressed air storage unit supplied by a compressor. Where the stored supply of compressed air is depleted, the energy storage device may continue to supply electricity on demand through operation as a heat engine, with the compressor being driven directly (e.g. on a same rotating shaft) or indirectly (via generated electrical power) by the expansion system. Multiple expanders of the same or different types (e.g. rotating, reciprocating), may be utilized in parallel and/or in series (e.g. multiple stages) depending upon the particular application. Multi-stage embodiments featuring internal combustion in low pressure stages, may be particularly suited for placement in vehicles.

    摘要： An apparatus performs a power cycle involving expansion of compressed air utilizing high pressure (HP) and low pressure (LP) air turbines located upstream of a gas turbine. The power cycle involves heating of the compressed air prior to its expansion in the HP and LP air turbines. Taking into consideration fuel consumption to heat the compressed air, particular embodiments may result in a net production of electrical energy of ˜2.2-2.5x an amount of energy consumed by substantially isothermal air compression to produce the compressed air supply. Although pressure of the compressed air supply may vary over a range (e.g. as a compressed air storage unit is depleted), the gas turbine may run under almost constant conditions, facilitating its integration with the apparatus. The air turbines may operate at lower temperatures than the gas turbine, and they may include features of turbines employed to turbocharge large reciprocating engines.

    摘要翻译： 一种装置利用位于燃气轮机上游的高压（HP）和低压（LP）空气涡轮进行包括膨胀压缩空气的动力循环。 动力循环包括在HP和LP空气涡轮机中膨胀之前对压缩空气进行加热。 考虑到用于加热压缩空气的燃料消耗，特定实施例可以导致基本上等温空气压缩消耗的能量的净产量为-2.2-2.5倍，以产生压缩空气供应。 虽然压缩空气供应的压力可以在一定范围内变化（例如，当压缩空气存储单元耗尽时），燃气涡轮机可以在几乎恒定的条件下运行，从而有助于其与设备的集成。 空气涡轮机可以在比燃气涡轮机低的温度下操作，并且它们可以包括用于涡轮增压大型往复式发动机的涡轮机的特征。

    摘要： Embodiments relate to valves comprising a member such as a plate or poppet, that is moveable relative to a stationary seat. The state of the member may be maintained against opposing forces with relatively little expenditure of energy. According to one embodiment, a poppet displaced from seating in the valve seat, may be held in position against opposing forces tending to close the valve, until a desired flow of gas through the valve has taken place. The poppet may then be released as desired, such that those opposing forces serve to passively close the valve. The valve may be secured in position utilizing mechanical, magnetic, electromagnetic, pneumatic, electrostatic, or hydraulic approaches. Valve embodiments may be particularly suited to controlling gas flows for compression and/or expansion in an energy storage system.
