A hydraulic accumulator can be immediately used as an energy source because it already stores a volume of pressured hydraulic oil. The most widely used accumulator is one in which hydraulic oil is contained with an overpressure of nitrogen. Energy is stored via compression of the nitrogen; the hydraulic oil serves as the working fluid.
