I hope you're corrrect, but I am skeptical of storage tech following wrights law as the paper suggests. The current battery projects are tiny and I suspect there will be greater costs from scaling them than Wright's law suggests. Not to say they won't get cheap, but that they will get cheaper slower than a simple exponential decay relationship suggests. Just the scale of materials required and the fact that battery tech has been around for a long time. I suspect we have got more of the low hanging fruit than with PV. Again, I hope I'm wrong.
