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.

Technical design of gravity storage. The energy production of gravity storage is defined as: (1) E = m r g z μ. where E is the storage energy production in (J), m r is the mass of the piston relative to the water, g is the gravitational acceleration (m/s 2 ), z is the water height (m), and μ is the storage efficiency.

Gravity batteries might be the answer. The idea sounds simple – when there is plenty of green energy, the batteries use the power to lift a heavy weight either high into the air or to the top of a deep shaft. Then when the power is needed, winches gradually lower the weight, and produce electricity from the movement of the cables.
