> First it was "batteries will never scale to grid usage"

You're inventing a straw man that's easier for you to attack.

No goalposts are being moved. My point was, and still is, that batteries do not presently scale sufficiently to make a predominantly wind and solar grid feasible, and our current projections even a decade out do not see them scale to that point either.

We don't know if some breakthrough in battery chemistry will make it scale. Could such a breakthrough transpire? Sure. But will it happen? We don't know. And thus we should not gamble massive infrastructure spending on the assumption that this breakthrough will happen.

At this point, nuclear fusion is a safer bet than grid scale battery backup.

You should tell that to the companies who are already deploying grid scale batteries.

What are those companies, and how large are those battery deployments?
