This doesnt account the short duration of batteries, I have to replace them every time they go past their lifetime, so in the long term their cost is much highe

- PeterisP 5y agoThe heavy machinery with moving parts lifting thousands and thousands of tons is also going to need maintenance and wear&tear replacements. The problem with scale is that all these proposed gravity batteries need much, much more machinery than an equivalent pumped capacity pumped hydro or chemical battery plant.
- polypodiopsi 5y agoOut of interest: do you have experience with mechanical engeneering or is this more of a common sense speculation?
- mplewis 5y agoThis is something made easier by the fact that we understand how mechanical designs age. We've built high-standing structures with parts that move in a similar way that last decades. We understand how to maintain those structures without totally replacing them.
