Publication number: 20160273529Abstract: 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: June 1, 2016Publication date: September 22, 2016Inventors: Karl E. STAHLKOPF, Danielle A. FONG, Stephen E. CRANE, Edwin P. BERLIN, JR., AmirHossein POURMOUSA ABKENAR

Publication number: 20150354556Abstract: 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 (?-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.Type: ApplicationFiled: June 5, 2015Publication date: December 10, 2015Inventors: Danielle A. FONG, AmirHossein POURMOUSA ABKENAR, Edwin P. BERLIN, JR., Philip Le Roux

Publication number: 20150345522Abstract: Embodiments of the present invention use compressed air to store and deliver electrical, mechanical, and/or thermal power with high round-trip efficiency. Various embodiments may be scalable for use in a variety of environments—from wind farms to power plants to motor vehicles. An energy storage system according to the present invention can operate as a stand-alone storage system that connects electrically to the grid, it can be tightly integrated with a wind turbine, and/or it can be co-located with a thermal power generation facility and operate with even higher efficiency by scavenging low-grade waste heat.Type: ApplicationFiled: June 23, 2015Publication date: December 3, 2015Inventors: Danielle A. FONG, Stephen E. CRANE, Edwin P. BERLIN, JR., AmirHossein POURMOUSA ABKENAR
