The earliest form of a device that used gravity to power mechanical movement was the pendulum clock, invented in 1656 by Christiaan Huygens. The clock was powered by the force of gravity using an escapement mechanism, that made a pendulum move back and forth. Since then, gravity batteries have advanced into systems that can utilize the force due to gravity, and turn it into electricity for large scale energy storage.

Based on the obtained LCOS results (Fig. 15), gravity Storage systems are the most cost-effective energy storage technology used in large-scale application. For the studied system size of 1 GW power capacity and 125 MW energy capacity, the LCOS of GES is about 202 $/MWh, followed by CAES (190 $/MWh), PHES (2015 $/MWh) and Li

Photovoltaic cells produce electric energy in a short interval during a period of low demand and show high levels of intermittency. One of the well-known solutions is to store the energy and convert it into a more stable form, to transform again into electricity during periods of high demand, in which the energy has a higher value.

Gravity Power is the only storage solution that achieves dramatic economies of scale. PNNL conducted a study to calculate the LCoE (levelized cost of energy) for 14 storage technologies, grouped into Pumped Storage Hydroelectric, Hydrogen, Flow, and Lithium Ion. The Gravity Power technology is by far the most cost-effective.

Depending on the considered scenarios and assumptions, the levelized cost of storage of GES varies between 7.5 €ct/kWh and 15 €ct/kWh, while it is between 3.8 €ct/kWh and 7.3 €ct/kWh for gravity energy storage with wire hoisting system (GESH). The LCOS of GES and GESH were then compared to other energy storage systems.

StratoSolar gravity energy storage stores energy by raising relatively small masses (hundreds of tonnes) from the ground to the buoyant platforms at 20,000 meters using electric motor/generator driven winches.
