Abstract
The invention relates to methods and systems for the storage and recovery of energy using open-air hydraulic-pneumatic accumulator and intensifier arrangements that combine at least one accumulator and at least one intensifier in communication with a high-pressure gas storage reservoir on a gas-side of the circuits and a combination fluid motor/pump, coupled to a combination electric generator/motor on the fluid side of the circuits.
Claims20
A compressed gas-based energy storage and recovery system comprising a staged energy conversion system suitable for the efficient use and conservation of energy resources, the system comprising:
- a compressed gas storage system;
- a first cylinder assembly having a first chamber and a second chamber separated by a boundary mechanism, wherein at least one of the chambers is a pneumatic chamber, the first cylinder assembly being configured to transfer mechanical energy from the first chamber to the second chamber at a first pressure ratio;
- a second cylinder assembly having a first chamber and a second chamber separated by a boundary mechanism, wherein at least one of the chambers is a pneumatic chamber, the second cylinder assembly being configured to transfer mechanical energy from the first chamber to the second chamber at a second pressure ratio greater than the first pressure ratio;
- and
- a control system for operating the compressed gas storage system and the first and second cylinder assemblies in a staged manner to provide a predetermined pressure profile at, at least one outlet.
A compressed gas-based energy storage and recovery system comprising a staged energy conversion system suitable for the efficient use and conservation of energy resources, the system comprising:
- a compressed gas storage system;
- at least three cylinder assemblies, each having a first chamber and a second chamber separated by a boundary mechanism that transfers mechanical energy therebetween, wherein at least one of the first and second chambers is a pneumatic chamber;
- and
- a control system for operating the compressed gas storage system and the at least three cylinder assemblies in a staged manner such that at least two of the cylinder assemblies are always in at least one of an expansion phase during an expansion cycle and a compression phase during a compression cycle.
