Publication number: 20150054291Abstract: 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.Type: ApplicationFiled: November 5, 2014Publication date: February 26, 2015Inventors: Karl E.

Patent number: 8851043Abstract: 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.Type: GrantFiled: March 15, 2013Date of Patent: October 7, 2014Assignee: LightSail Energy, Inc.Inventors: Michael Coney, Karim Wazni, Danielle A.

Publication number: 20140262739Abstract: 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.Type: ApplicationFiled: January 23, 2014Publication date: September 18, 2014Applicant: LIGHTSAIL ENERGY, INC.Inventors: Danielle A.

Patent number: 8723347Abstract: An energy storage and recovery system employs air compressed utilizing power from an operating wind turbine. This compressed air is stored within one or more chambers of a structure supporting the wind turbine above the ground. By functioning as both a physical support and as a vessel for storing compressed air, the relative contribution of the support structure to the overall cost of the energy storage and recovery system may be reduced, thereby improving economic realization for the combined turbine/support apparatus. In certain embodiments, expansion forces of the compressed air stored within the chamber, may be relied upon to augment the physical stability of a support structure, further reducing material costs of the support structure.Type: GrantFiled: September 14, 2012Date of Patent: May 13, 2014Assignee: LightSail Energy, Inc.Inventors: Stephen E.

Publication number: 20140060467Abstract: 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.Type: ApplicationFiled: November 4, 2013Publication date: March 6, 2014Applicant: LightSail Energy, Inc.Inventors: Danielle A.
