The company, Energy Vault, has commercialized the ultimate energy storage technology that will build the foundation of a clean energy future – brick by brick.
The Energy Vault stores excess electrical energy by efficiently transforming it into gravitational potential energy using 35-ton bricks that can be raised and lowered at will, and that can sit still storing the energy for any amount of time, before transforming the energy back to electrical energy when needed.
This idea has applications for storing excess energy from the grid from any energy source if it proves economically competitive. The idea is beautiful in its simplicity and generalization of pumped water storage in the mountains.
