Embodiment Construction

[0026] Referring to FIGS. 1A-1D, a cryogenic container 10 constructed in accordance with the invention is illustrated. The cryogenic container 10 includes an outer vessel 12, and an inner vessel 14 suspended within the outer vessel 12. The outer vessel 12 and the inner vessel 14 and are generally cylindrically shaped, fluid tight tanks having internal volumes selected as required. Rather than being cylindrical, the outer vessel 12 and the inner vessel 14 can have other shapes, such as cylindrical.

[0027] Both the outer vessel 12 and the inner vessel 14 can comprise any material commonly used in the construction of Dewar-type cryogenic tanks, such as steel, stainless steel, or non magnetic stainless steel. In addition, the inner vessel 14 can be suspended within the outer vessel 12 using any conventional structure, such as support rods or rings (not shown).

[0028] Since size of the cryogenic container 10 is a key to portability, it is preferred that for portable applications, the cry...

Abstract

A cryogenic container includes an inner vessel for containing a cryogenic fluid, and an outer vessel for insulating the cryogenic fluid from the environment. The inner vessel includes a superconductive layer formed of a material having superconducting properties at the temperature of the cryogenic fluid. The superconductive layer forms a magnetic field around the cryogenic container, that repels electromagnetic energy, including thermal energy from the environment, keeping the cryogenic fluid at low temperatures. The cryogenic container has a portability and a volume that permits its' use in applications from handheld electronics to vehicles such as alternative fueled vehicles (AFVs). A SMES storage system includes the cryogenic container, and a SMES magnet suspended within the cryogenic fluid. The SMES storage system can also include a recharger and a cryocooler configured to recharge the cryogenic container with the cryogenic fluid.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a division of Ser. No. 11 / 132,135 filed May 18, 2005.FIELD OF THE INVENTION [0002] This invention relates generally to cryogenic containers for storing cryogenic fluids. This invention also relates to superconductivity magnetic energy storage (SMES) using cryogenic containers. This invention also relates to methods for shielding cryogenic fluids from thermal energy. BACKGROUND OF THE INVENTION [0003] Cryogenic containers, such as dewar type containers and cryogenic tanks, are used to store cryogenic fluids such as liquid nitrogen, oxygen, hydrogen and neon. A conventional cryogenic container includes an inner tank configured to contain the cryogenic fluid, and an outer tank configured to provide a thermal barrier between the cryogenic fluid and the environment. In addition, the outer tank forms an annulus around the inner tank in which insulation, and in some systems a vacuum, is contained. The outer tank and the ann...
