How does a pumped storage hydropower project work?

Pumped storage hydropower projects use electricity to store potential energy by moving water between an upper and lower reservoir. Using electricity from the grid to pump water from a lower elevation, PSH creates potential energy in the form of water stored at an upper elevation, which is why it is often referred to as a “water battery”.

Is pumped storage hydropower the best resource for long-duration energy storage?

“Pumped storage hydropower has proven to be America’s most effective resource for long-duration energy storage,” said Cameron Schilling, NHA’s Vice President of Market Strategies and Regulatory Affairs. “The acceleration of wind and solar deployments underscores the increasing need to integrate large amounts of variable resources.

What is the current state of pumped storage hydropower technology?

Although pumped storage hydropower (PSH) has been around for many years, the technology is still evolving. At present, many new PSH concepts and technologies are being proposed or actively researched. This study performs a landscape analysis to establish the current state of PSH technology and identify promising new concepts and innovations.

How many terawatt-hours can a closed-loop pumped storage hydropower system produce?

A GIS-based analysis of potential new closed-loop pumped storage hydropower (PSH) systems in the contiguous United States, Alaska, Hawaii, and Puerto Rico finds technical potential for 35 terawatt-hours (TWh) of energy storage across 14,846 sites, which represents 3.5 terawatts (TW) of capacity when assuming a 10-hour storage duration.

What is a pumped storage hydropower guidance note?

The guidance note delivers recommendations to reduce risks and enhance certainty in project development and delivery. It also equips key decision-makers with the tools to effectively guide the development of pumped storage hydropower projects and unlock crucial finance mechanisms.

Is pumped storage hydropower the world's water battery?

Below are some of the paper's key messages and findings. Pumped storage hydropower (PSH), 'the world’s water battery’, accounts for over 94% of installed global energy storage capacity, and retains several advantages such as lifetime cost, levels of sustainability and scale.
