Just today I read about Styrofoam being used for hydrogen storage--that might pair well with this design.

KISS - my kind of design...

Airborne styrofoam - just what this planet's oceans need!

No, that would stay inside.

Since smoking has been reduced and weather radar invented--I would feel better about flying in a hydrogen airship.

Glad to see that safety is a priority,especially considering past accidents with hydrogen airships.
On the positive side hydrogen is cheaper than helium & more buoyant.

@martinbayer : H2 would be released via a catalytic reaction. Hence, with exception of natural venting, the hydrogen would be safely contained within the Styrofoam compounds.

Here, we can suspect a LH2 composite tank releasing H2 gas into the contained vessels (see how the hull is hermetic) and a Fuel cell working with gaseous H2 to provide power (although the absence of visible inlet would suggest they went with a battery with/or a Stirling engine (that because of the insulated line running bellow the airship to the aft section)).

The trials comes amid a growing need for systems that can provide a persistent capability to monitor oceans and other bodies of water.
