Pumped hydro energy storage systems for a sustainable energy

Pumped hydro storage (PHS) is a form of energy storage that uses potential energy, in this case water. It is an elderly system; however, it is still widely used nowadays, because it presents a mature technology and allows a high degree of autonomy and does not require consumables, nor cutting-edge technology, in the hands of a few countries.
