Cryogenic container and superconductivity magnetic energy storage (SMES) system

A cryogenic container comprising:

• an inner vessel configured to contain a cryogenic fluid at a selected temperature range;
• an outer vessel surrounding the inner vessel;
• and
• a superconductor material lining a surface of the inner vessel having superconducting properties at the selected temperature range configured to shield the cryogenic fluid in the inner vessel from thermal energy transmitted through the inner vessel;
• wherein the material is not permanently attached to the inner vessel.

A system for storing electrical energy comprising:

• an inner vessel configured to contain a cryogenic fluid at a selected temperature range;
• an outer vessel surrounding the inner vessel forming an annulus between the inner vessel and the outer vessel;
• a material on the inner vessel having superconducting properties at the selected temperature range;
• a superconducting magnetic energy storage (SMES) magnet in the inner vessel configured to store the electrical energy;
• a recharger configured to inject a compressed cryogenic gas into the inner vessel for recharging the cryogenic fluid;
• and
• a cryocooler configured to supply the recharger with a supercritical fluid.
