An apparatus and method of storing and transporting, in a dual-use cryogenic storage tank, a cryogenic liquid having a liquefaction temperature. A first pump empties the tank of a first portion of the cryogenic liquid, thereby leaving a second portion of the cryogenic liquid in the cryogenic storage tank. A second portion of the cryogenic liquid is focused at a location on a bottom of the cryogenic storage tank. Using a second pump located at the location, the cryogenic storage tank is emptied of the second portion of the cryogenic liquid, whereby a residual portion of the cryogenic liquid is left therein. Using a focused heating structure, heat may be delivered to the location to raise the temperature of the residual portion above the liquefaction temperature, thereby vaporizing all of the residual portion.

A storage system for storing a cryogenic medium. The storage system includes a dual-wall cryogenic tank having an inner storage container for receiving the cryogenic medium and an outer container which surrounds the inner storage container. An evacuated hollow space is arranged between the inner storage container and outer container. A removal line serving as a removal duct forms a fluidic connection from the inner space of the inner storage container to a consumer connection. A first controllable line shut-off valve and a first heat exchanger are arranged in the removal duct. The storage system is operable such that, in the event of a crash, a shutdown of the storage system and escaping of the stored cryogenic medium is prevented. This is achieved via a first heat exchanger arranged within the evacuated hollow space, and a line shut-off valve which is arranged in the removal line. The line shut-off valve is operable, in the event of a fracture of a fluid-carrying connection, to automatically shut off fluid flow of the cryogenic medium.

A cryotank system comprising a first cryotank device and a second cryotank device. The first cryotank device includes a first cryotank to hold hydrogen, an extraction line operable to feed a consumer, a pressure sensor operable to measure pressure in the first cryotank, a heating line into which a partial flow of the extraction line can be branched off at a first junction, a first heat exchanger arranged in the first cryotank, wherein the heating line extends through the first heat exchanger and returns into the extraction line after the first heat exchanger at a second junction, at least one switching element operable to activate or deactivate the first heat exchanger in response to a measured pressure by the pressure sensor, and a first filling line operable to facilitate filling of the first cryotank with hydrogen. The second cryotank device includes a second cryotank to hold hydrogen, and a second filling line operable to facilitate filling of the second cryotank with hydrogen. A connecting line is operable to fluidically connect the first filling line to the second filling line.

In a system for dispensing a cryogenic fluid, a bulk tank is configured to contain a supply of a cryogenic liquid. A sump is configured to receive cryogenic liquid from the bulk tank. A first positive-displacement pump is positioned within the sump and is configured to be submerged within and pump cryogenic liquid stored within the sump. A second positive-displacement pump is positioned within the sump and is configured to be submerged within and pump cryogenic liquid stored within the sump. A vaporizing heat exchanger is configured to receive and vaporize cryogenic liquid pumped from the first pump and/or the second pump.

A flow control panel is configured to control a flow of fuel from a storage bank to a dispenser. The flow control panel includes input and output flow controllers, and input and output ports, each output port coupled to a respective dispenser port. Each output flow controller is coupled to a respective input port and a respective output port, and is configured to enable the flow of fuel from the input port and the output port. A processor is configured to control the input flow controllers and the output flow controllers. The processor is coupled to a memory storing instructions that when executed by the processor cause the processor to: receive a desired fuel pressure value from a dispenser; receive indications of fuel pressures within each of the storage banks; select a desired storage bank having the lowest fuel pressure among the storage banks that have fuel pressures greater than the desired fuel pressure; and activate a desired input port and a desired output port to enable fluid flow from the desired storage bank to the dispenser.
