Pumped hydro energy storage | Department of Energy and Climate

We need bold energy targets and a plan to meet them. We need action. The Queensland Energy and Jobs Plan sets a clear pathway for our energy system to reach 70% renewables by 2032. Also key to this transformation is long duration pumped hydro which will store energy when the sun isn''t shining and the wind isn''t blowing.

Pumped up: how ''high density hydro'' could supercharge global energy storage

Say energy storage and most imagine EV lithium-ion batteries. But a range of "long duration" concepts that store power for weeks rather than hours are coming to market, among them one called high-density hydro that uses a mud-brown slurry pumped through a long loop of plastic pipe on a hillside to store energy until it''s needed. With first systems now being
