Building pumped water storage in arid areas

What is pumped-hydro storage?

Pumped-hydro storage an effective alternative for water, energy and land nexus issues. Proposed arrangement for combining short- and long-term energy and water needs. Proposed arrangement for combining hydropower and pumped-hydro storage. Comparison of proposed pumped-hydro storage projects in the Zambesi river basin.

What is pumped storage hydropower & floating solar photovoltaics?

Pumped storage hydropower is a cost-effective and proven grid-scale energy storage technology, reducing variable renewable energy curtailment. Floating solar photovoltaics can address water availability issues in arid regions by floating on water bodies.

What is an example of pluri-annual pumped-hydro storage?

An example of SPHS is Limberg in Austria . Pluri-annual pumped-hydro storage (PAPHS) are rare, built for storing large amounts of energy and water beyond a yearlong horizon. Interest in this PHS type will increase due to energy and water security needs in some countries. An example of this is Saurdal in Norway [18, 22].

Can water be stored with pumped-hydro storage?

Given the need of energy to store water with pumped-hydro storage, it is important to analyze the existing renewable energy potential of the region. The average wind speed across the river basin is small. There are only a few locations with average wind speeds higher than 7 m/s (Fig. 9 (a)).

What are the different types of pumped-hydro storage arrangements?

Existing pumped-hydro storage arrangements The most well-known PHS arrangements are open-loop, closed-loop and pump-back storage. Open-loop consists of a PHS plant where there is a significant stream of water to the upper or the lower reservoir (Fig. 4 (a)).

How pumped storage hydropower can improve the ecosystem Nexus?

This can improve the water, energy, food, and ecosystem nexus by enabling fast-track deployment of variable renewable energy in arid regions, while integrated pumped storage hydropower supports essential energy storage to the grid. Cost-saving by utilizing existing access roads and transmission lines in US$ 1. Introduction
