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.

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.

The battery proposal in Townsville will be the first ever to use this kind of technology in the country. To elaborate, the technology utilises surplus energy to raise 35-tonne blocks made from recycled materials. It works the same way as pumped hydro, in which it uses gravity to produce kinetic energy.
