Hydrogen-powered planes almost ready for takeoff
No they aren't, and they never will be (save for maybe a few small private one-offs). Certainly never for anything commercial.
While I certainly agree with the first part of your comment, what makes you sure they'll never be commercially viable? The energy density and application of liquid hydrogen is getting pretty good these days.
