Patent number: 9260966Abstract: Systems, methods and devices for optimizing heat transfer within a device or system used to compress and/or expand a gas, such as air, are described herein. In some embodiments, a compressed air device and/or system can include an actuator such as a hydraulic actuator that can be used to compress a gas within a pressure vessel. An actuator can be actuated to move a liquid into a pressure vessel such that the liquid compresses gas within the pressure vessel. In such a compressor/expander device or system, during the compression and/or expansion process, heat can be transferred to the liquid used to compress the air. The compressor/expander device or system can include a liquid purge system that can be used to remove at least a portion of the liquid to which the heat energy has been transferred such that the liquid can be cooled and then recycled within the system.Type: GrantFiled: October 7, 2013Date of Patent: February 16, 2016Assignee: General Compression, Inc.Inventors: Eric D.

Patent number: 9109511Abstract: Systems and methods for efficiently operating a hydraulically actuated device/system are described herein. For example, systems and methods for efficiently operating a gas compression and expansion energy storage system are disclosed herein. Systems and methods are provided for controlling and operating the hydraulic actuators used within a hydraulically actuated device/system, such as, for example, a gas compression and/or expansion energy system, within a desired efficiency range of the hydraulic pump(s)/motor(s) used to supply or receive pressurized hydraulic fluid to or from the hydraulic actuators. In such a system, a variety of different operating regimes can be used depending on the desired output gas pressure and the desired stored pressure of the compressed gas. Hydraulic cylinders used to drive working pistons within the system can be selectively actuated to achieve varying force outputs to incrementally increase the gas pressure within the system for a given cycle.Type: GrantFiled: November 11, 2011Date of Patent: August 18, 2015Assignee: General Compression, Inc.Inventors: Eric D.

Publication number: 20150125210Abstract: An underground fluid storage structures formed by mechanical excavation of a subsurface formation in a controlled fashion. The structure comprises vertical holes (260, 270) and transversal caverns (256) of circular section and preferably in spiral arrangement. Storage caverns as described herein may further employ hydraulic pressure compensation to prevent wide pressure variations in the storage caverns, and to provide relatively constant injection and discharge pressures when introducing or releasing stored fluids. The preferred application is compressed air energy storage (CAES) systems for storing energy in the form of compressed air in order to generate electricity.Type: ApplicationFiled: May 17, 2013Publication date: May 7, 2015Inventors: Eric D.
