Over time, this vision has evolved into two main technological pathways: Superconducting Magnetic Energy Storage (SMES) and superconducting flywheel energy storage systems. Both use superconducting materials but store energy in different physical forms (magnetic fields versus rotational motion).
Storing energy by driving currents inside a superconductor might be the most straight forward approach – just take a long closed-loop superconducting coil and pass as much current as you can in it. As long as the superconductor is cold and remains superconducting the current will continue to circulate and energy is stored.
As early as the 1960s and 70s, researchers like Boom and Peterson outlined superconducting energy systems as the future of energy due to their extremely low power losses. Over time, this vision has evolved into two main technological pathways: Superconducting Magnetic Energy Storage (SMES) and superconducting flywheel energy storage systems.
Yes. There are two superconducting properties that can be used to store energy: zero electrical resistance (no energy loss!) and Quantum levitation (friction-less motion).
Superconducting batteries are the real energy gain from high-T c superconductors. There are, however, limits to this approach. A back of the envelope calculation reveals that this approach may not completely revolutionize the energy economy.
