working on it, bazillion over budget and tbc years late.
i think we have some smaller pumped hydro projects that aren’t a cluster fuck.
batteries are just cheaper and less risky.

Make a business that pumps water up hill for 3 hours and sell it back at night?

Says they’re good for 2-5 years for full daily cycling.
Not bad not super… Pump and turbines still sounds more eco.

Sounds more eco maybe, significantly less efficient, and the amount of area you’d need would be pretty massive. You lose energy to the pump and the turbine. Chemical energy storage is the most efficient, the batteries can be recycled. Lithium iron phosphate batteries are another option. en.wikipedia.org/…/Lithium_iron_phosphate_battery
