"which means they will always be more expensive than natural gas"
The median cost of pumped hydro is ~20% premium over natural gas[1]. Nothing a carbon tax cant solve.
Though this source claims that it would not be feasible to rely only on pumped hydro, due to the scale. [2]

- chris_va 10y agoA carbon tax would solve the problem. Actually CCS is only about 15% more expensive, so it wouldn't even be that painful. Pumped hydro works really well, 85% efficiency, but there aren't .any places to put it.
- patall 10y agoWell, there were plans for big hollow concrete spheres at the ground of off-shore wind power plants. And Belgium thought about an artifical island with a lowered water level lake inside.
