The storage technology incorporates basic principles of physics that have been used in the production of pumped hydropower plants for years. In pumped hydro systems, water flows down from an upper reservoir to a lower reservoir, passing through and rotating a generator or turbine. Energy Vault has developed a six-arm crane to lift 5,000

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
Foundations: The total supported mass of a gravity energy storage system will include the lifted weight, as well as significant weight from the lifting system, which will include a number of very heavy components such as the winch drum. The total load to be supported by foundations is 100s of tons in all cases and is measured in 1000s of tons
You can use dead weights, but you need a huge amount of weight. For example the biggest pumped hydroelectric system in the world (the Gianelli Hydroelectric Plant in California, USA) uses water stored in a

But for lagre energy storage the weight and height have to be huge. Here are some formulas: 1watt = 1joule/second This allows you to "charge" the system with a smaller amount of available energy, since lifting a 100 kg weight is less work/energy than lifting a 10,000 kg weight. The available "spare" power could potentially be smaller power
Energy Vault, Gravity Power, and their competitors seek to use the same basic principle—lifting a mass and letting it drop—while making an energy-storage facility that can fit almost anywhere.
When electricity demand is high, the weights descend by the force of gravity and potential energy converts back into electricity (Fig. 1). A specific GES configuration that uses pulley systems working in tandem with a motor-generator to move the weights is known as lifted weight storage (LWS).

A specific GES configuration that uses pulley systems working in tandem with a motor-generator to move the weights is known as lifted weight storage (LWS). Figure 1. Schematic of LWS. Source: The energy capacity of LWS is proportional to the cumulative potential energy of weights
Other electricity storage technologies involving weights include those being developed by Gravitricity, Gravity Power (shown below), and Ground-Breaking Energy Storage (effectively cutting a large cylinder of earth and then raising it by pumping water underneath). We can also use buoyancy as a means of storing energy.
In a multiweight system where weights are stacked on top of each other at the base of the shaft, and removed at the top of the shaft for storage at ground level, the energy stored by the first weight is the product of the individual mass of the weight, m, and the total depth of the shaft, H.
Single weight Gravitricity system The simplest design of an underground gravitational energy storage system is a single weight cycling in a straight vertical shaft from an upper to a lower position. As shown in Fig. 5.6, this single weight could be supported by a number of winches around the shaft head.
