hello thought I don't find the exactly figure, I know that the pressure you need to condense methane is much more high that the one need it for butane, propane and other typical commercial gases. if you really need it; you can use the formula from this page ( to calculate the pressure you'll need to condense it at 293K (20Cº).

But, let me ask : Why is it so important to have it liquid? Is it the volume/weight ratio?

If you don't get throw the formulas let me know, It will take me some time but I can do it.
