Abstract: Systems and methods for operating a hydraulically actuated device/system are described herein. For example, systems and methods for the compression and/or expansion of gas can include at least one pressure vessel defining an interior region for retaining at least one of a volume of liquid or a volume of gas and an actuator coupled to and in fluid communication with the pressure vessel. The actuator can have a first mode of operation in which a volume of liquid disposed within the pressure vessel is moved to compress and move gas out of the pressure vessel. The actuator can have a second mode of operation in which a volume of liquid disposed within the pressure vessel is moved by an expanding gas entering the pressure vessel. The system can further include a heat transfer device configured to transfer heat to or from the at least one of a volume of liquid or a volume of gas retained by the pressure vessel.

Abstract: Systems, methods and devices for optimizing bi-directional piston movement 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 a first pneumatic cylinder, a second pneumatic cylinder, a hydraulic actuator, and a hydraulic controller. The first pneumatic cylinder has a first working piston disposed therein for reciprocating movement in the first pneumatic cylinder and the hydraulic actuator is coupled to the first working piston. The second pneumatic cylinder has a second working piston disposed therein for reciprocating movement in the second pneumatic cylinder. The hydraulic controller is fluidically coupleable to the hydraulic actuator and is operable in a compression mode and an expansion mode.

Abstract: 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. For example, systems, methods and devices for optimizing the heat transfer within an air compression and expansion energy storage system are described herein. A compressor and/or expander device can include one or more of various embodiments of a heat transfer element that can be disposed within an interior of a cylinder or pressure vessel used in the compression and/or expansion of a gas, such as air. Such devices can include hydraulic and/or pneumatic actuators to move a fluid (e.g., liquid or gas) within the cylinder or pressure vessel. The heat transfer element can be used to remove heat energy generated during a compression and/or expansion process.
