1. An ionic liquid-based accumulator system comprising:
(a) a high-pressure vessel (100) having a single internal compartment (102), a top surface (104A), and a bottom surface (104B), wherein said high-pressure vessel (100) comprises:
(i) a gas orifice (108) located at said top surface (104A) adapted to allow flow of gas to and from said single internal compartment (102); and
(ii) a liquid orifice (112) located at said bottom surface (104B) adapted to allow flow of an ionic liquid to and from said single internal compartment (102);
(b) an ionic liquid holding vessel (200) operatively connected to said liquid orifice (112), wherein said ionic liquid holding vessel (200) comprises an ionic liquid;
(c) an ionic liquid pressurizing device (400) adapted to delivering an ionic liquid to said single internal compartment (102), thereby pressurizing said single internal compartment; and
(d) a high-pressure gas filling vessel (500) that is operatively connected to said high-pressure vessel (100), wherein said high-pressure gas filling vessel (500) is adapted for delivering or transporting a gas under high-pressure to a vehicle, container, or a vessel,
wherein flow of the ionic liquid to and from said internal compartment (102) acts as a pressure accumulator.
