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.

A method and apparatus fueling vehicle with gaseous fuel includes storage vessels, dispensing sub-stations and a controller. The storage tanks or vessels can be at different pressures. The plurality of dispensing sub-stations each include a dispensing hose and a control valve. Each dispensing sub-station is in controllable fluid communication with the storage vessels so that fluid can flow from the storage vessels through the dispensing sub-station to a vehicle tank. A dispensing hose, and a control valve of the dispensing sub-stations are in the fluid flow paths. The controller receives feedback indicative of a filling parameter from the dispensing sub-stations, and provides control signals to the control valves of the first and second dispensing sub-station to implement one or more desired fill schemes.

摘要:
Abstract A method and system is disclosed for delivering a cryogenically stored fuel in a gaseous state into the air intake system of a gaseous fuelled internal combustion engine. The method comprises determining the flow rate capacity in the engine system's fuel delivery line, comparing the determined flow rate capacity to a required flow rate demand and supplying fuel in gaseous state directly from the vapor space of the cryogenic storage vessel to the fuel delivery line that supplies fuel to the engine, when the flow rate capacity is equal to or higher than the required flow rate demand. The method further comprises activating a cryogenic pump to deliver fuel to the internal combustion engine from the liquid space of the cryogenic storage vessel when the determined flow rate capacity is lower than the required flow rate demand.
