No, if you ran hydrogen peroxide through a still first of all it would be very dangerous. Peroxides can be very unstable. Hydrogen peroxide exists naturally as a gas. A solution is made by bubbling it in water. If you were to put a solution of hydrogen peroxide through a still you would if anything; purify the hydrogen peroxide; or you would concentrate it to the point of blowing yourself up. The only way the you can separtae hydrogen and oxygen from a solution is by using a electrochemical cell.

Liquid hydrogen can be made by placing hydrogen gas under pressure and storing it in a tank.

There is such a thing as crystallized hydrogen however you would have to get it soooo cold, near ~1-20 Kelvin if you were to see any at all. Basically by cooling it you are going from a gas to a liquid to a solid.

Hydrogen peroxide is unstable; it disproportionates into H2O and O2. You can accelerate the process by heat; you do not need and should not try to distill it.

Hydrogen is a gas at room temp. As with any gas, compressing and cooling will convert it to a liquid provided you keep it cold and under pressure.

If you cool liquid hydrogen enough it will become a solid as does anything else.

It takes tremendous energy to convert Hydrogen into a liquid; a lot more to convert it to a solid.

If you ran water, alcohol, acetone... through a still, would you be separating the hydrogen away the oxygen?

Hydrogen is liquefied by adiabatic expansion after cooling the compressed gas below its Joule-Thompson inversion temperature. The liquid must be run through iron-doped charcoal or other suitable catalyst to (exothermically) equilibrate ortho- and para-hydrogen spin isomers at 20 K.

Hydrogen melts at 14 K.

No.

Hydrogen peroxide is water with an extra *oxygen* atom, not hydrogen.

Hydrogen in the liquid and solid state exist only in the coldest reaches of the universe, near absolute zero temperature.

How do you make liquid hydrogen ?

It be very, very hard. H2 (l) boils at 20.28 K
(−252.87 °C, −423.17 °F)
Thats only 20.28 K above absolute zero

Is there such thing as crystallized hydrogen ?
As in, solid.
Yes, again, it be very difficult to synthesize, as it can only exist below 14.01 K

(In short for both, its more-or-less impossible on Earth)

If you try to distill hydrogen peroxide you will definitely blow yourself up. This happened to a student while I was in grad school. Fortunately no one died but there was a lot of blood.

No, you will get water and oxygen but not hydrogen.
