Airships have one, tremendous problem: Hydrogen. Helium is too expensive and is running out, and hydrogen, well see the Hindenburg. There's a lot of research into "safe hydrogen" but despite decades of research (and money) there has not been any success. Until you can overcome the fizzy lifting gas issue airships will remain a dream.
