After spending 2 billion euros and 14 years, Switzerland has finally completed the construction of a hydropower facility with a total length of no more than 11 miles, nearly 2,000 feet underground between the Emosson and Vieux Emosson dams in Valais. The reason it took so long was because the project required manual tunneling in the Alps and was divided into two large bodies of water at different heights.
The power plant is equipped with six pump turbines built by Nant de Drance and has an installed capacity of 900 MW.
In addition, through pumped hydro storage - moving water from lower areas back to higher pools during idle times to "shaving peaks and filling valleys" - the facility can also store approximately 20 million Kilowatt hours of energy.
In recent years, renewable energy has been a widely discussed topic around the world. This pumped storage power station in Switzerland takes nearly 20 hours to clear the Vieux Emosson reservoir.
Last month, researchers from the International Institute for Applied Systems Analysis (IIASA) also shared a new system based on gravitational potential energy - using elevator devices common in high-rise buildings to generate electricity. and energy storage.
A few days ago, a Finnish company also manufactured a new type of battery that can use sand to store heat.
