First of all, is it even possible for me to liquify hydrogen without the use of advanced and expensive lab equipment?  Basically I want to do this in my house safely. I have NO ambition to burn Hydrogen, just looking into safe storage techniques.

If it is possible, how would I go about doing it? I know how to create hydrogen gas easily, but liquifying is a whole different ball game. Do I use Liquid Helium to cool the gas Hydrogen? Or do I just keep pressurizing the Hydrogen until it's liquid?

It is very hard for me to find resources online on how this process works exactly.

No.  You need super-high pressures or super-low temperatures.  In households this isn't an option without some kind of special equipment.

How much do you need?  Why not keep it as high-pressure gas?  Way easier...just need a gas cylinder and some valves and stuff.

No "or" here. You need low temperature - 33 K is max.

Thanks for clearing that up.

Now I know that LH2 is out of the picture, looks like I will have to go with gas hydrogen. Which is fine because when hydrogen is injected into any internal combustion engine it's gas anyways. Right?

To store the gas hydrogen, could I use any normal propane tank that gas grills use? Would this be sufficient enough?
