Gravity batteries can have different designs and structures, but all gravity batteries use the same properties of physics to generate energy. Gravitational potential energy is the work required to move an object in the opposite direction of Earth's gravity, expressed by the equation whereis gravitational potential energy,is the mass of the object,is the acceleration due to gravity (9.8 m/son earth), andis the height of the object.

When the national grid calls for the energy, the gravity battery lowers those weights, and generates energy with the electric motor-generators. The Rudong gravity energy storage system is part of China’s Zero-Carbon Parks initiative, and national 30-60 net carbon neutral plan.
The basic idea behind a gravity battery system is to lift a heavy object, such as a large mass of concrete or a weight, on a pulley, using energy from a power source. When energy is needed, the thing can fall, and the potential energy is converted back into electricity.
Gravity batteries store gravitational potential energy by lifting a mass to a certain height using a pump, crane, or motor. After the mass is lifted, it now stores a certain gravitational potential energy based on the mass of the object and how high it was lifted.
The collaboration is to develop a 100MW Hybrid Gravity Energy Storage System, a solution designed by Energy Vault for underground mines, pairing their modular gravity storage and batteries. According to a press release by Energy Vault, the energy storage solution will be deployed 1640 feet (500 meters) deep mine shafts.
A gravity battery is a type of energy storage device that stores gravitational energy —the potential energy E given to an object with a mass m when it is raised against the force of gravity of Earth (g, 9.8 m/s²) into a height difference h.
That’s relatively small—for comparison’s sake, the Ludington pumped storage plant in Michigan has a capacity of 1,875 megawatts, which can power a community of about 1.4 million people. Energy Vault says that subsequent gravity storage facilities it plans to build will be able to run at gigawatt-hour scale for 12 hours.
