The downside of PSH of course is the massive reservoirs you have to create, but they have astonishingly good efficiency (I was skeptical when I first heard of the concept, but real-world examples can hit an 80% efficiency target which more than makes up for the constant replacement of batteries and the potential impact of sourcing lithium or other materials depending on who is mining them). |
