Pumped hydro energy storage in Australia – Snowy 2.0 vs. sea water

Pumped hydro energy storage in Australia – Snowy 2.0 vs. sea water To support a 100% renewable electricity sector Australia will need approximately 10 terawatt-hours of long-term energy storage. The multi-billion-dollar Snowy 2.0 pumped hydro project will supply only 0.35 terawatt-hours, a small fraction of this, and conventional pumped hydro potential elsewhere in Australia, including […]

How Chile’s electricity sector can go 100% renewable

How Chile’s electricity sector can go 100% renewable If pumped hydro plants that use the sea as the lower reservoir can be put into large-scale operation Chile would be able to install at least 10 TWh of pumped hydro storage along its northern coast. With it Chile could convert enough intermittent solar into dispatchable form […]

The Valhalla solar/pumped hydro project

The Valhalla solar/pumped hydro project When and if it gets built the Valhalla project will consist of a 600 MW solar farm and a 300 MW pumped hydro plant which, it is claimed, will in combination deliver continuous baseload power to Northern Chile. If the project works as planned it will indeed deliver continuous baseload […]
