I have got a science project and my teacher has recommended me to do "Liquefying Hydrogen". I have been continuously thinking about that but I have not come to a solution. Can anyone please tell me how to liquefy and store hydrogen??

  • $\begingroup$ If you have been continuously thinking about it, why don't you write a bit how far you got and what the actual difficulties are that you encountered? Even the first 2-3 google hits for "liquefying hydrogen" can guide you in the right direction. (Hint: it's really difficult without quite a bit of equipment) $\endgroup$ – Alexander Jun 17 '12 at 15:23
  • $\begingroup$ The boiling point of Hydrogen (at one atmosphere) is around 20 Kelvin (which is something you could have found with a trivial google search), it requires a significant cryoplant to produce it in any quantity and sophisticated handling to maintain it for study. I fear that if you didn't know these things you probably aren't ready to consider this project. $\endgroup$ – dmckee --- ex-moderator kitten Jun 17 '12 at 15:34
  • $\begingroup$ @dmckee - I don't think the project is to actually produce LH2 so much as think about how you would $\endgroup$ – Martin Beckett Jun 18 '12 at 3:18

    $\begingroup$ @MartinBeckett Ah...I guess being immersed in experimental physics for a long time can warp ones mind. I just assumed that "project" meant "do it". and this is rather a difficult thing to do. $\endgroup$ – dmckee --- ex-moderator kitten Jun 18 '12 at 13:45
  • $\begingroup$ Instead of only reducing the temperature, if there's any chance that you could increase the pressure conditions by a few atmospheres, I think it should serve the purpose. Nevertheless, I agree with Martin Beckett. It isn't very practical when you don't have access to the equipment. $\endgroup$ – Graviton Jun 21 '12 at 13:27
