    Abstract: 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.

    Abstract: Towards recovering thermal energy, an accumulator buffers a working fluid over an energy recovery cycle that includes two processes: one in which working fluid is accumulated in the accumulator at increasing pressure and the other that draws working fluid from the accumulator at decreasing pressure. Heat storage fluid is displaced in a storage fluid conduit towards a heat storage region in response to increasing pressure in the accumulator and towards a reservoir region in response to decreasing pressure in the accumulator. One or more heat exchange conduits traverse the storage fluid conduit to come in thermal contact with the heat storage fluid where they transfer heat to the heat storage fluid during the first process of the energy recovery cycle and transfer heat from the heat storage fluid during the other process.

    Abstract: A device for fluid power recuperation with increased efficiency and safety may be used in stationary and mobile applications, such as road building machines, hoisting and conveying equipment as well as hydraulic hybrid vehicles.The device comprises at least one hydropneumatic accumulator communicating via its gas port with at least one gas receiver. The receiver is made in the form of an aggregate of cells communicating with the gas port of the accumulator via the collector, wherein the ratio of the receiver volume to the area of the cells internal surfaces does not exceed 0.01 m.At gas compression or expansion in the receiver the heat exchange between the gas and the cells walls occurs at reduced distances, with smaller temperature differentials, which increases reversibility of the heat exchange processes and recuperation efficiency.The aggregate of the receiver cells should be preferably embodied in a honeycomb structure where the partitions between the cells are connected with one another and the outer shell of the receiver. Taking some part of the load the partitions unload the outer shell, which allows making it less strong and massive and producing receivers of various shapes and dimensions ratio, thus facilitating integration of the device into the existing systems, including vehicles.

    Abstract: A hydropneumatic accumulator with a flexible porous filler intended for fluid power recuperation in hydraulic systems with a high level of pulsations includes a shell where a gas port and a fluid port are connected, respectively, with a gas reservoir and a fluid reservoir of variable volume separated by a movable separator. The flexible porous filler fills the gas reservoir so that the separator movement reducing the gas reservoir volume compresses said filler. The filler is connected with internal walls of the gas reservoir with the possibility of stretching the filler at the separator movement increasing the volume of the gas reservoir. The accumulator contains means of protection of the filler boundary layer against rupture made with the possibility of reducing local deformations of the boundary filler layer in case of jerks of the separator. Development of residual deformations of the filler during multiple recuperation cycles and destruction at non-uniform motion of the separator with strong jerks are prevented.
