An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a heater.

A cryogenic fluid fueling system includes a first container configured to contain a first cryogenic liquid with a first headspace being positioned above the first cryogenic liquid. A heat exchanger vaporizes a portion of the first cryogenic liquid such that pressure within the first container is raised as vaporized cryogen moves into the first headspace. A second container is configured to contain a second cryogenic liquid with a second headspace being positioned above the second cryogenic liquid. A condensing coil is positioned within the second headspace of the second container and fluidically connected to the first interior of the first container such that a portion of the first cryogenic liquid is propelled into the condensing coil and is warmed to provide a first cryogenic vapor.

Systems and methods for dockside regasification of liquefied natural gas (LNG) are described herein. The methods include providing LNG from a LNG carrier to a regasification vessel. The LNG may be regasified on the regasification vessel. The regasified natural gas may be discharged with a high pressure arm to a dock and delivered onshore. The regasification vessel may be moored to the dock. The LNG carrier may be moored to the regasification vessel or the dock.

Systems and methods are provided for a combined defuel and priority panel for a fueling station. The defuel and priority panel is configured to defuel a compressed natural gas (CNG) vehicle and direct the defueled gas to fuel other CNG vehicles at the panel fueling and defueling site. The defuel and priority panel is also configured to store defueled gas in defuel storage tanks, which can then be used to later fuel CNG vehicles.

A method and system for forming a compressed gas and dispensing it to a compressed gas receiver. The compressed gas is formed from a process fluid provided at a cryogenic temperature. The forming includes pressurizing the process fluid, feeding the pressurized process fluid at still a cryogenic temperature to a heat exchanger and heating it in indirect heat exchange with a thermal fluid which is provided in a reservoir at a thermal fluid temperature above the cryogenic temperature of the pressurized process fluid. Once heated to a suitable temperature the compressed gas may be dispensed to the compressed gas receiver or stored in one or more compressed gas storage vessels for later use.

A system and method for cooling a liquid cryogenic fluid user with an inert and non-pressurized liquid cryogen in 120K to 200K temperature range is provided. This includes maintaining the first liquid cryogenic fluid within a first predetermined temperature range with the sub-cooler and/or the recirculation pump, maintaining the second liquid cryogenic fluid within a second predetermined temperature range with the heat exchanger, and recondensing the second liquid cryogenic fluid using the pressurized first liquid cryogenic fluid.

A system for dispensing a cryogenic fluid includes a bulk storage tank configured to contain a supply of the cryogenic fluid. A heat exchanger coil is positioned in the headspace of at least one intermediate fluid tank, which contains an intermediate fluid, and is configured to receive and warm a cryogenic fluid from the bulk storage tank via heat exchange with intermediate fluid vapor in the headspace. A buffer tank receives fluid from the heat exchanger coil. A chiller coil is positioned within the intermediate fluid tank and is submerged within intermediate fluid liquid contained within the at least one intermediate fluid tank. The chiller coil receives fluid from the buffer tank and cools it via heat exchange with intermediate fluid liquid within which the chiller coil is submerged for dispensing.
