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.
There is also the issue that if building nuclear plants takes too long and is too expensive to be the solution, then such a project would also be too late to matter. Also transmission losses likely mean this is a solution for much less of the world population than you think. If we had a truly global lossless grid, then we would need much less energy storage to begin with.
Impracticalities aside, absurd geoengineering what-ifs are entertaining. Thanks for sharing.
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
