Gravity energy storage is a form of mechanical energy storage that uses the earth''s gravity to store energy. The energy is stored in the form of potential energy, which is the energy that an object possesses due to its position relative to other objects. The higher an object is placed, the greater its potential energy.

5 · Here are four innovative ways we can store renewable energy without batteries. Giant bricks are not what most people think of when they hear the words "energy storage", but they are a key element of a gravity-based system that could help the world manage an increasing dependence on renewable electricity generation.
If the world is to reach net-zero, it needs an energy storage system that can be situated almost anywhere, and at scale. Gravity batteries work in a similar way to pumped hydro, which involves
Energy start-ups around the world have begun using gravity as an alternative form of clean energy storage. It may help mitigate the disadvantages of other energy storage techniques, some of which have become environmental issues in themselves despite all being part of the shift away from fossil fuels.
