Germany is building the world’s first wind turbines with built-in hydroelectric batteriesGeneral Electric’s engineers in Germany are installing wind turbines with a hydro-power generation solution for when the wind isn’t blowing.
General Electric say that this is the first time wind and water power generation have been combined in this way.
It is essentially a pumped hydropower solution. Excess energy pumps the water up the wind turbine, and when the wind isn’t blowing, the stored potential energy is unleashed as gravity pulls the water down into a man-made lake at the bottom of each wind turbine.
The project will be implemented in the Swabian-Franconian forest and will feature the tallest turbines in the world, standing at 246.5m.
It is expected that this project will serve as a test case for other sites.
