I assume there must be a way of flattening the output using massive batteries at the point of production or small ones at the point of consumption. No idea how feasible that is. Household "powerbanks" are still very expensive.

Yes, to a degree, (and this is one area where renewable tech can improve) but then batteries have their own environmental/ethical issues. Plus if you try to imagine how big a battery you would need to heat your a house for even and hour in winter, then it's clear there's a way to go.

You can always plug your car to the home grid :)

Battery costs esp. at the utility scale is going down fairly fast, stationary storage is growing fast now. Household powerbanks are probably generally in an uncomfortable cost/utility spot, market isn't big enough to drive down prices. rmi.org/the-rise-of-...

Bess can marginally help but not fully. That's why countries like want a firming power, like gas or nuclear Easiest way to see it is to simulate the grid based on last 5-10y data to have 100% ren+bess coverage. For Germany it's clearly impossible to do it only with bess. Maybe for NZ it could be?
