The context of these comments it the idea that stored electric power in batteries can take over from fossil fuel energy; and that the capability in batteries is "there." I don't believe it.
The construction at scale of batteries, and battery manufacturing facilities is going to take a very long time. For example, the mining capacity for copper, cobalt, lithium, and so on DOES NOT EXIST to produce the amount of Li-ion batteries. The same can be said for any other candidate materials. Current capacity serves the current market. It can't be any other way. If you want a bunch more, it will take a while; and when demand outstrips supply cost goes way up. Therefore, *batteries are not "there."* Nor will they be there any time soon. *If you run the numbers,* instead of just wishing, it is unlikely grid storage can be done at all with batteries alone. It will require other very significant storage tech. Even supplying cells for more than a million cars is not currently possible. I happily own Tesla stock on the thinking they have a leg up on supplying cells to the auto industry. But there is no denying it: the supply of batteries is meager. Batteries are a fine solution for mobile applications, airliners, trucks, cars, even boats. However, for enabling all renewable power on the grid, batteries do not make sense. It will take too many batteries. Also they are not material efficient for stationary applications - some other solutions are needed. Pump storage is bad because there are limits to how much land we want to flood. Nuclear? I don't like it though plenty of people do. I am hoping in the long time frame that fusion gets worked out (then it may not be necessary to have grid storage at all, though mobile storage might still be useful). Lot of talk about compressed air, I tend not to believe that is possible. I think hydrogen could be useful. Conversion efficiencies are not good, but great big tanks underground are within the realm of possibility. Some other chemical reaction might work, but I can't guess at that.
