Hydrogen, cheap and plentiful, is very dangerous to handle.

Helium is very safe... and we are running out of it.

we can "liberate" hydrogen from water.

The major commercial source of helium is natural gas which contains an average of 0.4% helium. Not exactly where we want to continue getting Helium.

There are many other commercial uses for Helium as well, not just for those mylar party balloons that you get for graduations and birthdays.
