[Digestion] delivering biogas in cylinders

[adkarve]

I am conducting trials on compressing biogas in cylinders and to distribute
it as cooking energy to householders. The idea is to install a large,
centrally located biogas plant and to provide householders daily with about
500 g of methane in a cylinder. I would not be attempting to liquify methane
but just to compress it in order to reduce its volume. I was told by an
energy expert that by not removing the carbon dioxide from the biogas, one
may be able to accommodate more methane in a cylinder, because methane
dissolves in liquid carbon dioxide.  Thus, one compresses biogas till the
carbon dioxide is liquified, and the methane in the mixture automatically
dissolves in liquid carbon dioxide. I am neither an engineer, nor a
physicist, but a biologist. Can any members of this group tell me whether
the above procedure would be better than filling the cylinders with pure
methane?
