Again not far. Fuel cells to be used that allow for storing solar reliably, by all means, provide the evidence of the fuel cell industry making this possible not wishful proprietary technologies

>provide the evidence of the fuel cell industry making this possible

Hang on, so, you want fuel cells but dismiss someone building the world's largest battery using redox flow technology?

I take it that you don't know that redox flow batteries are a type of reversible fuel cell? https://en.wikipedia.org/wiki/Flow_battery#Redox

I want fuel cells at scale that can work anywhere just like batteries, otherwise you dont have a useful solution to the already utopian all solar world you guys dream of.

That would be cheap redox flow batteries, like the EWE project I linked you to.

One thing, I take it you don't see lithium scaling. Why is that? There is enough of it.
