Abstract
In various embodiments, foam is compressed to store energy and/or expanded to recover energy.
Claims30
A method of storing energy, the method comprising:
- dispersing a heat-transfer liquid within gas to form a first foam having a first foam expansion ratio;
- compressing the first foam within a first cylinder assembly;
- thereafter, transferring a second foam to a second cylinder assembly different from the first cylinder assembly, the second foam having a second foam expansion ratio smaller than the first foam expansion ratio;
- compressing the second foam within the second cylinder assembly;
- exhausting the compressed second foam from the second cylinder assembly;
- and
- storing at least a gaseous component of the compressed second foam.
