H2 vertitube safety airship

direct possible explosion upwards
  [vote for,

H2 stored in vertical tubes, Upon accidental explosion, the tube rockets upwards leaving the rest of the airship safe, not affecting the rest of the tubes.

Details: Said airship has storage of hydrogen in lightweight vertical tubes, wider at the top and narrow at the bottom. Said tubes are to be kept apart via a set of vertical nitrogen filled tubes. In case of malfunction, and the explosion of said hydrogen inside said tube, the thrust of the explosion will be sent upwards and away from said airship, leaving rest of airship components (hereafter: "The components") safe.

I used to own an H2 - an insane machine... http://motorcyclema...-orgwikihydrogen-1/
A stock H2 was rated at 12.0 secs for the quarter mile. Updated with more power and better front disc brakes, the H2 became the undisputed king of the streets, even beating legendary muscle cars of the era such as the Plymouth Hemi Cuda. It was notoriously dangerous, being prone to up-and-over wheelies and speed wobbles. The dangerous handling characteristics arising from its mediocre frame design caused it to be nicknamed the “Widowmaker” by motorcycle enthusiasts of the 1970s. [normzone, Sep 17 2014]

(?) H2? NO! http://www.h2.no/

       Why are they wider at the top? Why do you want the tube to leave the airship? Why not just have a plug that blows out?   

       Bigger question: in hydrogen airships is the risk explosion or fire? Watching the Hindenberg disaster it is interesting to note that it burned but did not explode.   

       A reservoir failure that allows air to mix with the hydrogen could then allow explosion. You could watch for this by maintaining tubes at slightly more than atmospheric pressure and watching tube pressure or weight.   

       A fire would burn hydrogen as the tube failed and could occur without explosion. More tubes failing in the heat would feed the fire which would be limited by available oxygen.

       Solid'ish aerogel dirigible, pockets hollowed out to hold hydrogen... maybe something other than thermite to dope the skin.

       I think an H2 impregnated solid ag would outgas faster than you could keep it filled.

       The idea is to move the flame and heat out of the way as fast as possible, and before it affects the rest of the airship.   

       So if its thicker at the top, it is able to "slip out", or be shot out, clearing the airship from flames.
