Gravity energy storage is a form of mechanical energy storage that uses the earth''s gravity to store energy. The energy is stored in the form of potential energy, which is the energy that an object possesses due to its position relative to other objects. The higher an object is placed, the greater its potential energy.
Cranes are a familiar fixture of practically any city skyline, but one in the Swiss City of Ticino, near the Italian border, would stand out anywhere: It has six arms. This 110-meter-high starfish of the skyline isn''t intended for construction. It''s meant to prove that renewable energy can be stored by hefting heavy loads and dispatched by releasing them.
