Doesn’t look viable. Capacitors aren’t good enough for energy storage as it is and known dielectrics are thousands of times better than vacuum.
The actual solution is way more boring. It’s possible that even flow batteries will be too expensive and we’ll just spam the sodium version of server rack batteries.
