In the 1980s steel manufacturers created new alloy steels that were
specifically formulated to resist embrittlement as stainless steels
resist corrosion. Both Lockheed and Boeing explored the possibilty of
using thin sheets of this stuff to make liquid hydrogen fuel tanks for
airliners and estimated costs of supplying those airliners with
hydrogen.

And of course hydrogen is completely unsuitable as an aircraft fuel since its VOLUME is some
FOUR times that of kersosene.


For fuels that you have to LIFT through the AIR its energy per unit
weight, not energy per unit volume that is the issue.

Completely WRONG.

The huge volume of hydrogen storage required for an airliner would either require a more massive
structure (which itself is then much heavier) or you would have less payload.. Certainly it
wouldn't be compatible with existing airframes.

Of course it would also guaranteee a collosal explosion even in the event of a crash you could
walk away from today.

Hydrogen is a very very stupid fuel for transport applications.
