Apparently they are getting ~70% of their lift from the buoyancy and ~30% from their propeller.
In the video included in the article, they show their prototype flying. It is surprisingly lively for a blimp (I guess owing to the fact that it gets/needs lift from the propeller), darting around in an almost fish-like fashion. I dunno, still skeptical but the video does make it seem much more plausible, at least.
