What would it be used for?

They say humanitarian, cargo, and passenger.

I suspect the main one is cargo, to fit the “reasonably fast but low-cost” market between boats (very slow) and planes (expensive). This is presented well in this video: https://youtu.be/ZjBgEkbnX2I?feature=shared

A dirigible used for humanitarian purposes? They really missed an opportunity to name it "Oh, the Humanity!"

Sky yachts that can be put under a non-profit and marketed as humanitarian or "educational" or "research" platforms. I knew of a superyacht that was "studying" coral loss. Of course, at Fiji. Probably had to give one of the 8 staterooms to some academic.
