Scottish Power run an important part of our national electricity grid, called the Ben Cruachan pumped storage scheme.

When the nuclear power stations at Torness and Hunterston are generating more electricity than is needed, the extra is used to turn huge rotary pumps which lift water into an elevated cavern. When there is a daytime peak of electric demand greater than the power station output, the water is allowed to run downhill through the pumps which have been designed so that they act as turbines and re-generate most of the electricity that they used to lift the water previously. The benefit is that the power stations can run at a fairly steady load, which is more efficient.

It's not exactly storing electricity, but it's better than batteries!

Electrical energy cannot be 'saved' or 'preserved'--it can only be converted into other forms of energy which CAN be stored such as potential, chemical, mechanical. These forms can later be turned back into electrical energy. Each transformation has a loss associated with it, so you never get out quite the same amount you started with.............

Yeah, you can store energy in a superconducting ring. But the total energy storage is I²L/2 so it's kinda impractical. It's also difficult to extract energy from it since the magnetic field is static.

A friend of mine used to work for ARCO Solar and they stored energy in 'flywheels'. Steve would get a kick out of it (being an ME) because these flywheels massed around 50 kilos, ran in a vacuum, on magnetic bearings, and spun at about 150,000 RPM. According to Kenny, when one of them came apart it was *real* spectacular ☺

well, it kinda has to be created before it can be used... the world's not gonna run out of electricity or anything.

Now getting it from point A to point B is a whole other issue! Lol

You can also "save" electricity in a capacitor and for short periods of time an inductor. How about a superconducting ring?

No. Electricity is the flow of electrons. What ever one else has discussed is how to produce it. IE chemical or mechanical means.

you can store electricity in a battery. well DC anyway...now it only takes mechanical forces such as water turning wound rotor around a magnetic field. so why would we want to save it. you cannot "run out" of electricity.

Batteries are still the boon of energy storage.
Someday we will learn how to make our structures into batteries for energy storage of solar cells and wind generators!

Yes . Batteries
