Russia is planning to use airships as part of a $240bn transport project

Fuel

I always thought the biggest problem for long range airships was fuel, in that the further you flew, the more you had to carry at the beginning of the journey, and got burnt during the journey, which made the airship get lighter the further it went. They used to get around this by venting the hydrogen at a proportional rate so the flight remained level. However due to the expense of helium, this isn't really considered an option these day, hence few new airships.
