> While true, with sufficiently cheap transmission, no storage is needed.
Where "sufficiently cheap" here means "affordable over intercontinental distances".
I believe storage costs are falling faster than transmission costs.
The "intercontinental distances" part is simpler, and potentially* cheaper at current aluminium prices, than the domestic grid upgrades and repairs much of the west needs anyway.
* The scale is such that it's more of an opportunity cost than a dollar cost, what else can be done with 5% of Chinese aluminium per year for the next 20-or-so years.
But also, much research needed before a true price tag can be attached, rather than just a bill of materials
