Exactly. Day/night storage can probably be met (at least partially) by using EVs (i.e. arrive at work empty, recharge from solar, arrive at home full). But that’s not going to be enough to get through the winter in higher latitudes.
That’s why we need a reliable base load, and natural gas is very attractive because it’s:
- easier to build than nuclear
- way less polluting than coal
- compatible with existing supply lines
Battery storage is prohibitively expensive in many parts of the world, and there aren’t very many ready alternatives. I think we should be investing in nuclear power instead of utility grade battery backups, and we should be looking at EVs to help even out the day/night cycle.
