VIEUX – Switzerland succeeded in creating “ water battery ” with a capacity of 20 million kWh. Yes, of course not a portable battery that can be carried anywhere, but a power plant located between the Emosson and Vieux Emosson dams in Valais.
As reported by TechSpot, Friday (8/7/2022), this power plant is known to have been designed by Switzerland since 14 years ago. And unmitigated, the construction value reaches around € 2 billion or equivalent to Rp. 30.3 trillion.

This Swiss water battery project took a long time to complete because workers had to make tunnels first. The tunnel itself is very long, stretching more than 11 miles from the Swiss Alps.
Not to mention that this hydro battery consists of two large bodies of water at different heights which is not an easy task. In this case the two bodies of water lie nearly 2,000 feet underground between the two dams.
To note, excess energy from Switzerland’s newest power plant can be used to pump water from lower basins to higher pools. When the demand for power increases, the water in the higher pool is allowed to flow back into the lower reservoir.
When the water flows, it will turn a turbine that produces hydroelectric power. The power plant designed by Nant de Drance has six pump turbines that can generate 900 MW of power to sustain life in Switzerland.
This isn’t the only crazy renewable energy idea that’s been popping up lately. Last month, researchers from the International Institute for Applied Systems Analysis (IIASA) also shared similar ideas.
They came up with the idea of using a gravity-based elevator system in tall buildings to generate and store electricity . A few days ago also a company in Finland has created a battery that uses sand.
