167Wh/l is a relatively recent prototype, Redflow uses the older zinc-bromide which is only around 70Wh/l.

Yep. Next time someone claims base load means renewables don't work do that math. Also point to the experience in developing countries where they don't have reliable base load, yet have similar uptime.

That's a bad argument. Arbitrary energy transportation is not a solved problem. Power grids are designed to deliver from power plants to the consumers.
