There was a German company that tried to revive Airships as a Cargo platform and that didn't go past concept stage.
Having shared an office with a chap who worked on the German Cargolifter project, he said that one of the major issues they could not easily overcome was disposing of the water ballast. To take a large quantity of water (160 tons) to another part of the world and empty it on land, when taking on the next cargo, caused insurmountable problems with the possible transport of germs/bacteria etc. Airlander overcomes this by not being lighter than air. Instead it uses the helium to provide some buoyancy assistance, working alongside vectored thrust from the engines and aerodynamic lift from the envelope.
As has been mentioned many times, the Airlander 10 was originally built to meet an urgent US Army requirement. HAV were acting as a contractor to Northrop Grumman at the time. The short timescale and lack of project lead probably resulted in a number of compromises being made which the HAV people would like to avoid on subsequent craft. As such, the next Airlander will really be the one to watch.
