Can h2 be solid
WebHydrogen can also be stored by absorption or adsorption on to a solid, or by storing in a solid chemical form, which gives the hydrogen high density which makes it easier to find suitable storage space. ... This can easily be done using by using a binary gas analyzer calibrated for pure H2 and a fixed or portable hygrometer to check for ... WebAnswer (1 of 5): Whether hydrogen is a solid, liquid or gas depends on the temperature. It is a gas at most normal temperatures, as it boils at around 10K, which gives it the lowest boiling point of any element except helium. Yes, hydrogen can be stored in liquid form, and this has been done sin...
