10 years seems like a short time, what if we make it 30 years - same as solar? You would need to update it roughly once during your lifetime.
The other idea is having small communities that manage their own energy needs. Meaning 1MWh energy bank for 100 homes instead of 1GWh for 100 000 homes.
Battery life doesn't always work the way you want it to.
I don't know what the limits of different battery chemistry is, but I suspect it won't work. Though 10 years was just a number I made up, I think it is reasonable for discussion.
Yeah, I think you might be right although AFAIK they still hold on to about 80% of their initial charge after that time (10y), which is quite a lot. 30 years was just a random thought that seemed like a sensible minimum to be somewhat low-maintenance solution.
I am just trying to think about different possibilities, they pros, cons and what might be net win in this case. Your remark on people not wanting to service yet another thing is spot on, grid always works for them.
