In various embodiments, efficiency of energy storage and recovery systems compressing and expanding gas is improved via heat exchange between the gas and a heat-transfer fluid.
1. A compressed-gas energy storage and recovery system comprising: a cylinder assembly comprising a first pneumatic chamber for compressing gas to store energy and expanding gas to recover energy and a second pneumatic chamber, separated from the first pneumatic chamber;selectively fluidly connected to the first chamber, (i) a compressed-gas reservoir for storage of gas after compression and supply of compressed gas for expansion thereof, and (ii) a vent for exhausting expanded gas to atmosphere and supply of gas for compression thereof;a spray mechanism...
