System design and economic performance of gravity energy storage

The storage state (S L (t)), at a particular time t, is the sum of the existing storage level (S L (t-1)) and the energy added to the storage at that time (E S (t)); minus the storage self-discharge, δ, at (t-1) and the storage discharged energy (E D (t)), at time t. Energy losses due to self-discharge and energy efficiency (η) are also taken into account.

Gravity battery

Pendulum clock driven by three weights as "gravity battery". An old and simple application is the pendulum clock driven by a weight, which at 1 kg and 1 m travel can store nearly 10 Newton-meter [Nm], Joule [J] or Watt-second [Ws], thus 1/3600 of a Watt-hour [Wh], while a typical Lithium-ion battery 18650 cell [2] can hold about 7 Wh, thus 2500 times more at 1/20 of the weight.
