Shows energy storage but no energy is actually stored

Is energy easy to store?

All energy is difficult to store, not just eletrical. Indeed, electrical energy is quite easy to store once you consider the big picture. If you look at a tank of gasoline, you can see "wow, what a great storage for energy!".

Where is energy stored?

In the energy domain, oil in large cylindrical tanks at the edge of a city is stored energy. So is the wood in the trunk of a tree, the water in a reservoir behind a dam, and the heat in a tank containing molten salt made very hot by concentrated sunlight. Here, we are confining attention to the storage of electricity.

How can electricity be stored?

The only way through which it can be stored is by converting it into a more stable energy form which is storable with the intent of transforming it back to electricity when needed. There are various technologies which can be used to convert electricity to other forms of energy which can easily be stored.

What is an energy storage facility?

An energy storage facility is comprised of a storage medium, a power conversion system, and a balance of plant. This work focuses on hydrogen, batteries, and flywheel storage used in renewable energy systems such as photovoltaic and wind power plants.

How does energy get stored in this system?

Energy is stored in the magnetic field created by the flow of direct current in the coil. This energy can be stored as long as the refrigeration is operational. This system consists essentially of a coil of cryogenically cooled superconducting material, a power conditioning system and a refrigeration system.

Can energy be stored kinetically?

Energy is of course transported as a kinetic energy (a current through the grid); but if it would be possible to also store it kinetically, less conversion would be needed. Moreover, energy would be stored (in some kind of PEC storage loops) and transported by the electricity grid.*
