6 FAQs about [Pumped storage and electric energy storage]

What is pumped storage hydropower?

Pumped storage hydropower is a type of hydroelectric power generation that plays a significant role in both energy storage and generation. At its core, you've got two reservoirs, one up high, one down low. When electricity demand is low, excess energy from the grid is used to pump water from the lower to the upper reservoir.

How do pumped storage systems work?

Releasing water from the upper reservoir through turbines generates power. This process is crucial during peak electricity demand periods. Design Efficiency: The design of dams in pumped storage systems is tailored to maximise energy storage and generation efficiency. This involves considerations of dam height, water flow, and storage capacity.

What are the benefits of pumped storage?

Utilising water, a renewable and abundant resource, minimises environmental impact, aligning with global energy sources and shifting towards greener options. High Efficiency: The technology in pumped storage, including advanced turbines and generators, is designed for high efficiency.

What is pumped storage hydropower (PSH)?

Pumped storage hydropower (PSH) is the world's largest battery technology, accounting for more than 90% of long-duration energy storage globally, surpassing lithium-ion and other battery types. PSH is a closed-loop system with an ‘off-river’ site that produces power from water pumped to an upper reservoir without a significant natural inflow.

How does Pumped Hydro Energy Storage (PHES) work?

PHES works by pumping water from a lower reservoir to a nearby upper reservoir when there is spare power generation capacity (for example, on windy and sunny days). The water is then allowed to return to the lower reservoir through a turbine to generate electricity when there is a supply shortfall (for example, during the evening).

Is a pumped-storage system worth it?

The pumped-storage system was seen by most as prohibitively costly, but it was almost universally viewed as technically capable of providing renewable support and peak power adequacy.
