Abstract: A storage system for temporary storage of a gas comprising a storage vessel configured to store a pressurized gas or liquid; at least one of a compressor configured to pressurize the gas and provide the pressurized fluid or a liquefaction apparatus operable to liquefy the gas to provide the liquid; and piping associated with one or more valves, wherein the piping and the associated one or more valves are configured to provide: (a) in a first configuration, inflow of the gas into the compressor or the liquefaction apparatus, wherein the compressor is configured to pressurize the inflowing gas to provide the pressurized fluid or wherein the liquefaction apparatus is configured to liquefy the inflowing gas to provide the liquid, and introduce the pressurized gas or the liquid into the temporary storage vessel; and (b) in a second configuration, outflow of the pressurized gas or liquid from the temporary storage vessel.
