    Abstract: A compression and expansion system includes a pressure vessel having a variable volume working chamber therein. The pressure vessel has a conduit through which at least one fluid can be introduced into and discharged from the working chamber. The system further includes a heat transfer element disposed within the working chamber and including a layer and at least one of a fin and a spacing element. The pressure vessel is operable to compress fluid introduced into the working chamber such that heat energy is transferred from the compressed fluid to the heat transfer element, and is further operable to expand fluid introduced into the working chamber such that heat energy is transferred from the heat transfer element to the expanded fluid.

    Abstract: 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.

    Abstract: Systems, devices and methods for the compression, expansion, and/or storage of a gas, such as air natural gas are described herein. In some embodiments, an apparatus suitable for use in a compressed gas-based energy storage and recovery system includes a pneumatic cylinder having a working piston disposed therein for reciprocating movement in the pneumatic cylinder, a hydraulic actuator coupled to the working piston, and a hydraulic controller fluidically coupleable to the hydraulic actuator. The apparatus is fluidically coupleable to a compressed gas storage chamber which includes a first storage chamber fluidically coupleable to the pneumatic chamber, and a second storage chamber is fluidically coupleable to the first storage chamber. The first storage chamber is disposed at a first elevation and is configured to contain a liquid and a gas. The second storage chamber is disposed at a second elevation greater than the first elevation, and is configured to contain a volume of liquid.

    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: An apparatus can include a piston movably disposed within a pressure vessel and defines a first interior region and a second interior region. The piston has a first position in which the first interior contains a gas having a first pressure and has a volume greater than the second interior region, and a second position in which the second interior region contains a gas having a second pressure and has a volume greater than the first interior region. A seal member is attached to the piston and to the pressure vessel. The seal member has a first configuration in which at least a portion of the seal member is disposed at a first position when the piston is in its first position, and a second configuration in which the portion of the seal member is disposed at a second position when the piston is in its second position.

    Abstract: A system for encouraging the use of renewable energy sources and suitable for the conservation of energy resources through the efficient management of energy storage and delivery includes connections to a power source, an energy storage subsystem, and a power grid. The system includes a power routing subsystem coupled to the source and grid, and adapted to operate in a bypass mode, in which energy is transferred from the source to the grid. The system includes a conversion subsystem coupled to the routing and storage subsystems, and switchable in substantially real-time between a storage mode, in which energy is transferred from the routing to the storage subsystem, and a generation mode, in which energy is transferred from the storage to the routing subsystem for delivery to the grid. The system also includes a controller for directing the modes based at least in part on a market factor.

    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 (210), a second pneumatic cylinder (230), a hydraulic actuator (272, 274), and a hydraulic controller (270). The first pneumatic cylinder (210) has a first working piston (220) disposed therein for reciprocating movement in the first pneumatic cylinder and the hydraulic actuator (272) is coupled to the first working piston (220). The second pneumatic cylinder (230) has a second working piston (240) disposed therein for reciprocating movement in the second pneumatic cylinder. The hydraulic controller (270) is fluidically coupleable to the hydraulic actuator (272, 274) and is operable in a compression mode in which gas is discharged from the second pneumatic cylinder (230) at a higher pressure than it enters the first pneumatic cylinder (210), and an expansion mode in which gas is discharged from the first pneumatic cylinder (210) at a lower pressure than it enters the second pneumatic cylinder (230).
