This is the first I've heard anything like this. What's your source for this?

You get highly variable solar output along a year. At least in the Northern Hemisphere where most people live. It depends on the place you are talking about.
Ideally you would store energy from the summer months to consume in winter. But you won't be doing that with sodium or lithium batteries. Just not cost effective for that kind of long term storage.
There are already things like that. like pumped hydro storage and hydrogen made from electrolysis
Good luck storing energy with either of those things on the scale of months. You do know that water evaporates right?
Hydrogen also permeates through things easily and worst of all is low density.
Why do you think nature uses sugars and fats instead? Plants split water into hydrogen and oxygen, but then store the hydrogen long term into fats. The hydrogen is only available inside cells, to move it outside cells it is converted into sugars, and for storage into fats.
this really should be in the climate thread. But it's important to note that currently the battery cost and capabilities and V2G tech available are plenty available to cover day to day variations. And that's definitely enough to cover things for a while. China isn't going to remove thermal electricity production overnight. In fact, Q3 thermal production was up YoY due to a very hot September.
There are plenty of things they can do to reduce carbon emissions over next few years. One of which is to increase ammonia fuel mix in the current coal plants. The pace at which they are developing things means they will probably come up with plenty of good solutions by the time they need to so.
Until then, the first thing they need to do is to install enough clean energy capacities to see coal power generation decrease YoY.

Ammonia is more reasonable, higher density than hydrogen, but it is also toxic and corrosive. Not to mention still a gas.
You can easily build pipelines for it, and it probably is possible to do underground storage for it similar to that for natural gas.

Hydro storage is already used on an industrial scale, its also relatively easy to build. Hydrogen was just an example and is used to make other fuels like ammonia.
Also, you know we already use plants to make biofuels already, right?
They need to power all those EV factories, and new EVs on the street. They also need power for AI modelling computation.
