Pumped-Storage Hydroelectricity

Pumped-storage hydro is a widely used energy storage method that relies on gravity to generate and store electricity.

How It Works

Water is pumped to an elevated reservoir using surplus electricity and released to flow through turbines, generating electricity when needed.

Benefits of Pumped Hydro

It provides large-scale energy storage, stabilizes the grid, and delivers high efficiency with minimal energy loss over time.

Challenges and the Future

High upfront costs and environmental concerns limit new projects. Suitable geography is essential, but advancements in design may expand its feasibility.
