I never said H2 is the solution (I do not believe so). I just said that batteries are NOT.

Who (other than ZeroAvia) is talking about batteries for flight?

For more information, please reread.

   "the cost of building safe low leakage infrastructure might exceed the cost of 
   batteries and solar/wind to produce power. You're probably better off making H2 
   dynamically where you need it and just sending electrons or storing them locally 
   in safe batteries."
