Question

Recently, the term "pumped-storage hydropower" is actually and appropriately discussed in the context of which one of the following?

Options

a

Irrigation of terraced crop fields

b

Lift irrigation of cereal crops

c

Long duration energy storage

Answer
d

Rainwater harvesting system

Explanation

Pumped-storage hydropower is the most established form of long-duration energy storage. It functions like a giant battery: it uses surplus electricity to pump water from a lower reservoir to a higher one, then releases the water through turbines to generate electricity when grid demand is high.

Think of pumped-storage not as a water resource project, but as a massive gravitational battery for grid stabilization.

Answer: (c).
