Pumped Storage

Pumped storage facilities are built to push water from a lower reservoir uphill to an elevated reservoir during times of surplus electricity. In pumping mode, electric energy is converted to potential energy and stored in the form of water at an upper elevation, which is why it is sometimes called a "water battery".

You can''t just pump water out of the top. You need to pump it out of the bottom. If you try to pump it out of the top, there''s a maximum amount of water you can pump: 10.4m. At that height, the negative pressure of your pump is sufficient to create a pure vacuum, boiling the water and creating cavitation.
