Abstract
Systems and techniques for compressed air energy storage and regeneration thereof are described herein. A compressor for compressed air energy storage and regeneration thereof can include a housing, a actuator, and a heat exchanger. The housing can define a volume. The actuator can be operable to expand the volume and compress the volume. The heat exchanger can be located at least partially within the housing. The heat exchanger can be configured to compress when the actuator compresses the volume, expand when the actuator expands the volume, and transfer heat with a working fluid.
Claims22
A system of compressed air energy storage, the system comprising:
- a motor powered by an energy source;
- a compressor operatively connected to the motor, the compressor defining a chamber, the compressor operable to pressurize a working fluid by altering a volume of the chamber between an expanded state and a compressed state;
- and
- a compressible heat exchanger within the chamber to transfer heat between the working fluid and the compressible heat exchanger.
A compressor for a stored energy system, the compressor comprising:
- a housing defining a volume;
- an actuator operable to expand the volume and compress the volume;
- and
- a heat exchanger located at least partially within the housing, the heat exchanger is configured to:
- compress when the actuator compresses the volume;
- expand when the actuator expands the volume;
- and
- transfer heat with a working fluid.
