Opening. Pumped hydropower storage (PHS), also called pumped hydroelectricity storage, stores electricity in the form of water head for electricity supply/demand balancing. For pumping water to a reservoir at a higher level, low-cost off-peak electricity or renewable plants'' production is used.

Historically this has meant pumped hydroelectric storage, a technology that is well developed, reliable, comparatively inexpensive, and seriously limited by a shortage of suitable reservoir sites. This variant of hydro storage is called underground pumped hydro (UPH) and is described in detail in this review, where it will be shown

Pumped storage hydropower (PSH) is a form of energy storage technology that has been in use for over a century. PSH projects store energy by pumping water from a lower reservoir to an upper reservoir when there is excess energy available, typically from renewable sources such as wind or solar.

Just 6 years ago, only 0.34 GW of non-pumped hydro storage energy storage could be found worldwide. In 2017, energy storage installations increased nearly 50% over 2016, close to 6 GW of capacity.
