Claim:
1. A thermo-mechanical energy storage system comprising: a first heat storage chain comprising: an apparatus comprising a plurality of loops, each loop comprising: wherein when the system is charging, the first heat storage chain is a first heat sink and at least a first one of said low pressure heat exchanging device and said high pressure heat exchanging device in at least a first one of said plurality of loops exchanges heat with a first heat source, and when the system is discharging, the first heat storage chain is a second heat source and at least a second one of said low pressure heat exchanging device and said high pressure heat exchanging device in at least a second one of said plurality of loops exchanges heat with a second heat sink, the first and second ones of said low pressure heat exchanging device and said high pressure heat exchanging device being a same heat exchanging device or different heat exchanging devices, and the first and second ones of said plurality of loops being a same loop or different loops.
