Electrical Energy from Water
Discover how pumped hydro storage systems work as the world's largest form of grid energy storage. Learn about sustainable energy storage through gravity and water systems.
How It Works
Pumped hydro storage uses electricity to pump water uphill during low demand periods, then releases it through turbines to generate electricity when needed.
Environmental Impact
Clean, renewable energy storage with over 80% efficiency. No emissions during operation and minimal environmental footprint.
Real-World Applications
Used worldwide for grid stabilization, peak load management, and renewable energy integration.
Station Demonstration
Step 1: Water Pumping
Observe how excess energy pumps water to the upper reservoir during off-peak hours.
Step 2: Energy Storage
See how potential energy is stored in the elevated water mass.
Step 3: Power Generation
Watch water flow back down through turbines to generate electricity on demand.
Step 4: Grid Integration
Learn how this system helps stabilize electrical grids with renewable energy sources.
