Technical FAQs 4

What is pumped hydro storage (PHS)?

Pumped hydro storage (PHS) is a clean and sustainable energy storage system that uses water to store energy. This storage system does not require any chemical substances and can store energy in a wide range of capacities. This storage system requires two reservoirs with different heights.

Can micro-pumped hydro energy power systems help rural areas?

Building micro-pumped hydro energy power systems from existing farm dams could also assist rural areas susceptible to power outages that need a secure and reliable backup power source.

How do micro-pumped hydro energy storage systems work?

Micro-pumped hydro energy storage systems store excess solar energy from high-production periods by pumping water to a high-lying reservoir, which is released back to a low-lying reservoir when more power is needed. Image: Supplied.

Could agricultural reservoirs be connected to micro-pumped hydro energy storage systems?

The study, published today in Applied Energy, finds agricultural reservoirs, like those used for solar-power irrigation, could be connected to form micro-pumped hydro energy storage systems – household-size versions of the Snowy Hydro hydroelectric dam project.
