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.
