India starts to build giant gravitational batteries

<pre>India starts to build giant gravitational batteries

The list of available renewable energy sources is constantly expanding. Soon, it will be supplemented by a new technology for generating and storing electricity based on gravity.

Energy Vault, based in California and Nevada, has just announced its first customers – Indian energy giant Tata and Mexican construction company CEMEX, purchase its gravity towers operating on the principle of hydroelectric power plants, only without water.

Its function is performed by massive concrete bricks. When there is excess energy available, they rise up, followed by their controlled fall, during which a generator is generated that generates electricity. According to Energy Vault representatives, the system is capable of storing from 10 to 35 MWh.

A full cycle of the “travel” of a concrete brick provides 90 percent energy storage efficiency. Another advantage of gravity towers is their versatility – they can be located almost anywhere where there is a piece of land and open space.
