I read the original report, which still includes figures of >$100 per kWh for storage, projected for multiple decades (if not in this report, in others). For a higher-latitude nation, we need TWh, probably tens of, for even a small nation. Be assured I have crunched these numbers and confirmed against our current best wind+PV resource data.

In other words, if we run a nuclear plant and deliberately induce a, as you say, "Fukushima-style cleaup", we are about comparable.

That's how expensive proper storage is. "Storage will save us", is frankly, an irresponsible lie that has killed.
