20110219763 | SYSTEMS AND METHODS FOR EFFICIENT PUMPING OF HIGH-PRESSURE FLUIDS FOR ENERGY STORAGE AND RECOVERY - In various embodiments, a mechanical assembly and/or storage vessel is fluidly coupled to a circulation apparatus for receiving pressurized heat-transfer fluid from an outlet at a first elevated pressure, boosting a pressure of the heat-transfer fluid to a second pressure larger than the first pressure, and returning heat-transfer fluid to an inlet at a third pressure. | 09-15-2011 |
20110315255 | SYSTEMS AND METHODS FOR REDUCING DEAD VOLUME IN COMPRESSED-GAS ENERGY STORAGE SYSTEMS - In various embodiments, dead space and associated coupling losses are reduced in energy storage and recovery systems employing compressed air. | 12-29-2011 |
20120000557 | SYSTEMS AND METHODS FOR REDUCING DEAD VOLUME IN COMPRESSED-GAS ENERGY STORAGE SYSTEMS - In various embodiments, dead space and associated coupling losses are reduced in energy storage and recovery systems employing compressed air. | 01-05-2012 |
20120006013 | HIGH-EFFICIENCY ENERGY-CONVERSION BASED ON FLUID EXPANSION AND COMPRESSION - In various embodiments, motor-pump efficiency is increased by limiting the fluid pressure communicated to the motor-pump to a range smaller than that communicated by other components of an energy storage and/or recovery system. | 01-12-2012 |
20120085086 | FLUID-FLOW CONTROL IN ENERGY STORAGE AND RECOVERY SYSTEMS - In various embodiments, compressed-gas energy storage and recovery systems feature one or more valves, which may be disposed within end caps of cylinder assemblies in which gas is expanded and/or compressed, for admitting fluid to and/or exhausting fluid from the cylinder assembly. | 04-12-2012 |
