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.
1. A method for energy recovery, the method comprising: within a first cylinder assembly, expanding a gas to produce a pressure smoothly decreasing over a first pressure range;producing, (i) from pressures within the first pressure range and in reaction to the gas expansion and (ii) within a second cylinder assembly mechanically coupled to the first cylinder assembly, a hydraulic pressure varying over a second pressure range smaller than the first pressure range; anddriving a motor via only the hydraulic pressure varying over the second pressure range,wh...
