A flywheel is a mechanical device specifically designed to efficiently store rotational energy, often used for maintaining steady speeds in engines, industrial machinery, and power plants. The most common use of flywheels in vehicles is within the engine. As the engine''s pistons move, they create a pulsing power output. The flywheel smooths
The issue with a flywheel is that you have friction while you are storing energy. The more energy you store, the higher loss rate, assuming normal bearing losses. With hydro, you have friction when you try to use the energy. You can store hydro as long as you want, simply shut the valve. You have a small loss from water evaporating perhaps.

Flywheels have been used for thousands of years, to store energy. The energy is stored through the angular momentum of a spinning mass. During charge, the flywheel is spun by a motor driven by electrical energy; during discharge, the same motor acts as a generator, producing electricity from the rotational energy of the flywheel.
