    摘要： Embodiments relate to techniques for forming underground caverns, and also to desalinization processes that may be employed in conjunction therewith. Particular embodiments form a salt cavern by introducing heated water into a salt formation, followed by removal of the resulting brine to leave a salt cavern. The injected water is provided as a result of a desalinization process of the brine. Concentrated brine resulting from the desalinization process, is used to form a solar pond whose stored thermal energy provides the heat source for the injected water. The resulting underground cavern may be employed to house large volumes of materials such as pressurized natural gas, liquid hydrocarbons, or compressed gas for energy storage. Also disclosed is a particular desalinization process based upon a Regenerative Evaporative Distiller (RED) structure, which efficiently leverages low grade heat available from the solar pond by relying primarily upon a latent heat of evaporation and condensation.

    摘要： Embodiments relate to architectures for pumps responsible for introducing liquid into cylinders reversibly configurable to perform gas compression or expansion. Particular embodiments maintain liquid flow rates in the face of the different pressure profiles (Δ-P) encountered during various portions of gas compression and gas expansion cycles. In some embodiments, the pump comprises multiple pumping elements per cylinder, at least one pumping element separable with a clutch and designed to spray/not spray during portions of compression/expansion cycles. Embodiments may employ phase difference(s) between the multiple pumping elements to introduce liquid in a desired manner. Mechanisms allowing adjustment in phase of multiple pumping elements, are also disclosed. The liquid may be introduced through sprayers arranged in rings in the cylinder, with rings (or partitions thereof) dedicated to spraying during different portions of compression and/or expansion. Embodiments may flow liquid to a gas compression/expansion cylinder via an intervening chamber of changeable volume.

    摘要： A compressed-air energy storage system according to embodiments of the present invention comprises a reversible mechanism to compress and expand air, one or more compressed air storage tanks, a control system, one or more heat exchangers, and, in certain embodiments of the invention, a motor-generator. The reversible air compressor-expander uses mechanical power to compress air (when it is acting as a compressor) and converts the energy stored in compressed air to mechanical power (when it is acting as an expander). In certain embodiments, the compressor-expander comprises one or more stages, each stage consisting of pressure vessel (the “pressure cell”) partially filled with water or other liquid. In some embodiments, the pressure vessel communicates with one or more cylinder devices to exchange air and liquid with the cylinder chamber(s) thereof. Suitable valving allows air to enter and leave the pressure cell and cylinder device, if present, under electronic control.

    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.
