>They don't have to be capable of being placed in every single possible location Yes, but I'm looking at this through the lens of where I live. My country has 40 times less GDP per capita than the US, and electricity has to be (and currently is) very cheap for people to afford it. Also, my country is very hot in summer and can be very cold in winter. It is a dry Central Asian region with up to 45-47C in summer and -10C in winter. Also, we had -27C last January which was a record cold and was a disaster. Here we have very good conditions for solar. Solar has become very cheap, and we are building several 100-400 MWh plants with more of them coming in the near future. But multi GWh battery storages for solar plants will cost billions. If we need to replace it in 5-10 years, this is not viable for us. But 30+ years or at least 25+ years is definitely worth looking at. Or, even if the life span is 10 years, it needs to be 3x cheaper per MWh storage than 30+ year option. But in that case, we'll have 3x more stuff to get rid of/recycle/pollute the environment.
