[Digestion] Safe Transportation of Low Pressure Biomethane for Social Gatherings

[Anand Karve]

Dear Jake,
 One can fill non-pressurised pure methane into inflatable bags and
transport it, but in this form you have to cary large volumes of it.
Secondly, you would have to use pressure for getting the methane from
the bag into your cookstoves. It would be easier If you could use
pressure at the facility where you produced the methane, and filled it
into rigid cylinders. Not only would the volume be reduced but the gas
would flow easily from the cylinder into the burners of the stove. We
have tested this concept as an experiment, using LPG cylinders as
containers and a pesticide pump for filling the cylinders.
Yours
A.D.Karve
