Power loss in a capacitor vs inductor
Capacitors exists with extremely little parasitic self-drain despite (near) full voltage across them so depending on capacitor type its seconds to months whereas inductors will have series resistance so freewheeling the current will deplete them rather quickly, in the ms to s range. – winny.

Superconducting magnetic energy storage
Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil which has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970.

Understanding Inductors: Principles, Working, and Applications
An inductor, physically, is simply a coil of wire and is an energy storage device that stores that energy in the electric fields created by current that flows through those coiled wires. But this coil of wire can be packaged in a myriad of ways so that an inductor can look like practically anything. Fortunately, for a schematic, the variations ...

Can you store energy in an inductor and use it later?
People have built a few superconducting magnetic energy storage units that store a megajoule of energy for a day or so at pretty high efficiency, in an inductor formed from superconducting "wire". I''ve been told that several electric utilities have bought a few such units and use them to improve power quality.

8.4: Energy Stored in a Capacitor
The expression in Equation 8.4.2 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q/C V = q / C between its plates.

Why do we want gap in the core material while designing inductor?
If we make an air-core inductor, this is invariably the thing that limits the maximum energy storage. If we wanted to run a higher current, we could do it briefly before the coil overheated. Ferromganetic materials like iron or ferrite limit the B-field in the core.
