A hydrogen fueling system and method comprises a container, a first tank, second tank, and third tank disposed within the container, and a nozzle coupled to the second tank and the third tank. One or more computer-readable storage media storing instructions executable by one or more processors may control flow of liquid hydrogen and hydrogen gas in the system, adjust temperature of the tanks, control pressure in the tanks, and transfer hydrogen gas from the second tank, the third tank, or a combination thereof to one or more target vessels. The system may also comprise flow control assemblies and flow control valves to manage the transfer of liquid hydrogen and hydrogen gas in the system.
摘要:
The invention relates to a method for filling a storage container (a vehicle tank, for example) (20) with a pressurized gaseous medium, in particular in the form of hydrogen. A supply storage system (2) for storing the hydrogen is connected to the storage container (20) to be filled via a tank supply line (3) and a filling valve (4). Prior to filling the storage container (20) with the medium, a flow of the medium is conducted through the tank supply line (3) while the filling valve (4) is closed in order to cool the tank supply line (3) to a definable target temperature, and the flow is discharged from the tank supply line (3) via a line (5) which branches off upstream of the filling valve (4). The invention further relates to a filling device (1) for filling a storage container (20).

摘要:
A superconducting device (9) including a superconducting coil is suitable for use in a nuclear magnetic resonance computer tomography (NMR-CT) apparatus which requires a highly-uniform, highly-stable magnetostatic field. However, a serious problem arises when a large-sized superconducting coil is to be installed in a small room of a hospital or the like. A superconducting device capable of solving this problem is disclosed in which a very low temperature vessel (1) having the form of a cylinder contains a superconducting coil in a state that the superconducting coil is immersed in a very low temperature coolant (12), and a very low temperature coolant inlet port (6) communicating the very low temperature vessel (1) for introducing the very low temperature coolant into the very low temperature vessel (1) is provided along a radial direction perpendicular to the horizontal center axis of the superconducting device and inclined at a desired angle with a vertical direction. The above superconducting device can be installed in a small room of a hospital, and makes easy a very low temperature coolant introducing operation.

摘要:
A novel tank cryogenic-compatible composite pressure vessel that beneficially utilizes Vapor Cooled Shielding (VCS) is introduced to minimize thermal gradients along support structures and reduces heat loads on cryogenic systems. In particular, the configurations and mechanisms to be utilized herein include: providing for a desired number of passageways and a given thickness of the VCS, reducing the thermal conductivity of the VCS material, and increasing the cooling capacitance of the hydrogen vapors.
