Abstract
A cryogenic energy storage system comprises at least one cryogenic fluid storage tank having an output; a primary conduit through which a stream of cryogenic fluid may flow from the output of the fluid storage tank to an exhaust; a pump within the primary conduit downstream of the output of the tank for pressurising the cryogenic fluid stream; evaporative means within the primary conduit downstream of the pump for vaporising the pressurised cryogenic fluid stream; at least one expansion stage within the primary conduit downstream of the evaporative means for expanding the vaporised cryogenic fluid stream and for extracting work therefrom; a secondary conduit configured to divert at least a portion of the cryogenic fluid stream from the primary conduit and reintroduce it to the fluid storage tank; and pressure control means within the secondary conduit for controlling the flow of the diverted cryogenic fluid stream and thereby controlling the pressure within the tank. The secondary conduit is coupled to the primary conduit downstream of one or more of the at least one expansion stages.
