Pumped hydro storage is great. The difference between it and batteries is that batteries can be constructed off site by a third party and then transported to your location.
Water towers have to be built on site, which can be difficult. Not to mention, to get appreciable storage, you have to build a really tall tower or a really big one. This is difficult too. Especially if you are in a location where the soil shifts or you get high winds. Because now your tower has to survive the elements.
There is definitely a strong case against water towers for distributed energy storage.
- sandworm101 7y agoConversion to or from electrical power is one option, but an elevated water storage (tower or simply up hill) reduces the need for larger water pumps. It means you don't have to run your well during dark hours. So it saves on electric use rather than provide actual electricity.
- _iyig 7y agoWhy not dig a pit? You can even load a big mass on top of the water for extra potential energy. Similar system from the age of steam: https://youtu.be/aKmi0PN7LxM https://youtu.be/aKmi0PN7LxM
