How do gravity batteries store gravitational potential energy?

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 stored gravitational potential energy is then transferred into electricity.

What are some examples of gravity batteries?

The most common example of a gravity battery today is also one in widespread use already. Power companies pump water into elevated reservoirs to store energy. Later, when they want to access that energy, the water is released and flows into another reservoir, flowing through a hydroelectric turbine before getting there.

Going underground – why Gravitricity energy storage makes sense

In the UK, for example, we have four pumped storage schemes totalling 2.8 GW, and whilst it is ideal for large-scale storage, the very specific geographies (not to mention huge capital cost) required means such schemes will always be relatively rare. The energy a gravity-based storage system can store and discharge is a function of mass
