Aerospace giant Airbus has unveiled plans for what it hailed as the first commercial zero-emission aircraft.

It said its hydrogen-fuelled passenger planes could be in service by 2035.

Airbus chief executive Guillaume Faury said the three ZEROe concept designs marked "a historic moment" for commercial aviation sector".

The use of hydrogen had "the potential to significantly reduce aviation's climate impact", he added.

Fight the future...or the past.

I guess with 50 years of proven oil reserves remaining, some businesses will be searching out other ways of fueling their vehicles.

All of a sudden hydrogen has become a safe fuel........ yet here i am thinking about the hindenburg

Hydrogen will either be stored in steel flasks/containers, or being generated in little doses just as much is needed at the moment to keep the engine running (via fuel cells). It is highly unlikely that there would be fires or explosions - even in a crash a pressured steel flask will probably not be damaged, and it could be put into some elastic foam.
Hydrogen is not inflammable without thoroughly mixing with air first.

When high-volatile fuel was first used in cars and planes there also was an outcry that those vehicles would be dangerous as bombs, but afterall it is all about technical questions.

OT airships are the "U-boats of the air", with static and dynamic lift being used for altitude changes.
The Hindenburg used hydrogen as a lifting gas (since the US did not want to sell helium to Germany or so some say), not for propulsion. Blaugas or a similar mixture was used for the engines. Because Blaugas weighs approximately the same as air, burning it and replacing its volume with air did not lighten the airship, eliminating the need to adjust buoyancy or ballast in-flight (like with conventional liquid fuels).

The lifting gas was not compressed and not mixed with atmospherical oxygen, which is why it was not inflammable - until one of the gas bags was ripped open..
