Lithium Battery
Lithium is widely used in batteries, ranging from cell phones to motor vehicles to industrial scale commercial battery operations

Pumped Storage Hydro
Typical: A dam is built in a river. When the water flows through turbines down river, it generates electricity.
By pumping water back into the dam from down stream, energy can be stored. The typical solution has been in implementation since 1907.
Variations: The fluid does not have to be water, other fluids work better. The dams do not have to be in a river. All that is needed is two holding areas, with sufficient differences in elevation.
These different variations are in different stages of implementation.

Mines, Mountains and Molehills
There are a large variety of gravity based storage solutions. They involve lifting and lowering heavy weights. These weights take many form, sand, rock, concrete and recycled windmill blades.
The lifting can take the form of free-standing cranes, cranes using old abandoned mine shafts and trains pulling wagons up and down a mountain.
