Interesting idea but.
>use massive hydrogen balloon to ascend as high as possible
Ballons don't really get that high. And getting to space is more about speed.

>use hydrogen in balloon as fuel to enter space
Hydrogen that is useful for balloons needs to be a gas, and hydrogen gas isn't very dense. So there wouldn't be much hydrogen to use. Look at the Space Shuttle tank, and notice how big the hydrogen tank is. That's just to carry liquid "dense" hydrogen.

>use balloon's envelope as parachute when landing
That could work though.
