This proposal is for an investigation into the use of superconducting bearings and motors running at cryogenic temperatures in an energy storage flywheel. Building on previous experience it appears that the ideal configuration for a cylindrically shaped flywheel is a journal bearing. This bearing has the dual advantages that it will be inherently stable and that it will have up to twice the stiffness of a passive magnetic bearing. In addition a large source of loss in an energy storage flywheel is parasitic loss which occurs in the iron core. The use of cryogenic temperatures presents the possibility that the reduction in ohmic losses makes it practical to use an air cored rather than an iron cored motor. Achieving this will allow flywheels to be used for diurnal storage in addition to their current applications.
