Eh, I've always looked at zero-point energy as being a nice science project but basically worthless as an actual power source for anything more than a second (you'd probably still need a matter-antimatter reaction to power a zero-point generator, IMO).
Well, it sounds like he's talking about a consumable power cell containing zero point energy, one that is rechargeable/ replaceable. There would be no need for a plant on board these ships, as no power is being generated. All generation occurs off-site prior to launch.
This is opposed to the m/am reactors that are essentially self-sustaining, but presumably larger. It'd be akin to using a nuclear reactor to generate the electricity needed to charge your electric car: its still nuclear powered, but not on board.
