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.
One storage type that challenges lithium-ion batteries is gravity batteries. Gravity batteries are great because they don''t require any rare metals that need to be mined for and can be used in a variety of different ways. Gravity batteries are a lot like flywheels in that they store energy as potential energy. It''s as simple as lifting a
