Partly so, in my opinion. I concur with the assessment that dezentralised energy storage capacities will – over a long strech of time – mostly benefit the military and its increasingly electricty-intensive equipment (drones, flight control, interception, AI managed swarms, etc.).

But that does not pertain to volatile #renewables like wind and sun whose effectiveness and suitability far more depend on grid structures, base loads of consumption and conventinal production, electricity markets, network costs, etc. That's one of the reasons, BTW, why I speak of #peakrenewables: They can positively contribute up to 30% in the overall electricity production, marketing, transfer, and consumption – beyond that it mainly increases costs and creates negative price offsets. And storage even for such minor for such capacities is not on the horizon. Hydrogen production on site of renewables is laughable (10% effectivness) and hydrogen powered plants are, well, not in sight.

Thus I think the current Tesla "Megapack" battery units (3.9 Mw/h storage per unit) is currently the best solution not for private, municipal, or commercial solutions but for military.

[Sidenote: And given the demand for batteries, I find it plausible that the vast lithium reserves in the Donbas region provided one of the main reasons for Putin to invade Ukraine.]
