It stores potential energy through the compression of a dry inert gas (typically nitrogen) in a container open to a relatively incompressible fluid (typically hydraulic oil). There are two types of accumulators commonly used today. The first is the bladder type (including diaphragm designs) and the second is the piston type.

The bladder contained in the shell is pre-charged with nitrogen gas to a pressure calculated based on system parameters and the work to be done.
