Could we use Hydrogen that is generated sing clean electricity or is too dangerous?

  It's possible, but even liquid hydrogen is not very dense and requires a lot of insulation. https://en.wikipedia.org/wiki/Tupolev_Tu-155 https://en.wikipedia.org/wiki/Tupolev_Tu-155

    Liquid hydrogen has about 4X the specific energy of Jet-A. But yes, the system as a whole isn't great once you consider what it takes to keep the H2 liquid...

      Energy density per unit of mass is about 3x in favor of hydrogen. Energy density per unit of volume is about 4x in favor of Jet-A.

        Sorry you are absolutely correct. Volume matters a lot, maybe almost as much as weight, for aircraft design.
