      I think it’s the physical size of the reservoir that is the limiting factor. You can’t reasonable expand most reservoirs, but it’s relatively easy to create new hydrogen/methane storage tanks.

        Yes but pumped storage is about 80% round trip efficiency vs power to x which is barely touching 20% out of the lab. And power to X needs an epic fuckton of very clean water, which also isn’t easy to find.
