Pumped hydro is both very geologically limited and environmentally detrimental. That technology alone will not substantially reduce the need for other power storage technologies/ peaker plants.
at least it works at scale relevant to grids. there are other interesting devices that store high grade heat in things like molten silicon or sand, then convert it to electric energy again, but it’s rather at prototype scale now i think. power to hydrogen is fine if it’s replacing hydrogen from natural gas, but it’s wack for storage of energy
