A cryogenic storage system basically includes a first cryogenic storage tank, a second cryogenic storage tank, a fluid transfer line and a cryogenic containment structure. The first cryogenic storage tank has a first predetermined capacity of liquefied gas. The second cryogenic storage tank has a penetration free bottom and a second predetermined capacity of the liquefied gas that is larger than the first predetermined capacity of the first cryogenic storage tank. The fluid transfer line is fluidly connected between the first cryogenic storage tank and the second cryogenic storage tank. The heat exchanger converts liquid exiting the first cryogenic storage tank to a higher pressure gas that is used as a motive force to move liquidized gas out of the second cryogenic storage.

A dosing vessel includes a reservoir having an inlet and an outlet and is configured to contain a supply of a cryogenic liquid with a headspace above. The outlet is configured to be connected to a dosing arm having a dosing head. A low pressure sensor is configured to detect a vapor pressure in the headspace. A high pressure sensor is configured to detect a pressure in a bottom portion of the reservoir. An inlet valve is in fluid communication with the inlet of the reservoir and is placed in communication with a source of cryogenic liquid. A controller is in communication with the high and low pressure sensors and the inlet valve and is configured to store a preset liquid level or a preset differential pressure corresponding to the preset liquid level, to determine a measured differential pressure based on data from the high and low pressure sensors and to control the inlet valve based on the measured differential pressure and the preset liquid level or the preset differential pressure so that a liquid level of a cryogenic liquid stored in the reservoir is generally maintained at the preset liquid level.

A portable, modular fueling system for the storage, dispensing and offloading of fuel from a rail vehicle to one or more other fuel storage vessels is disclosed. The system module is self-contained on an ISO standardized intermodal platform. The module is capable of being in fluid communication with a plurality of modular storage vessels, either rail-bound or wayside, such as for delivering fuel to a fuel tender or a locomotive. Electrical power, equipment storage, lighting, and compressed air may be located on the intermodal rail car or in a support module, such as either ground-based or rail-mobile. Alternatively, the platform can be mounted to a trailer chassis, or affixed to a land-based foundation matching the standardized intermodal container footprint. Control of the fuel system is provided by automatic means with manual override.
