Erm, no not a pressure vessel. A vacuum capacitor. They hold electrons, and they are able to charge and discharge in a fraction of a second, which is essential so that your floating power-bulb is able to haul-into port, discharge, and leave quickly. Batteries on a ship would take immense amounts of time, or immense amounts of copper; you pick. Vacuum capacitors are also empty, with a surfacing of Teflon for high electrical insulation, resulting in minimal capital; they are cheap, light, easy to mass-produce, and simple enough to automate their routes.
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.
