Jacob Ford : I will go all traditional on you and then see if I can talk myself out of a corner !
Because it would seem that the most efficient way to convert a bio-mass to bio-gas would be to have as a
feed stalk a super dense material, so as to produce the
greatest amount of Bio-gas per each single operation I would tend to go with a hard
wood, then a soft wood then any kind of a plant, excluding bamboo as not worth
the work !
Using ether coppicing or pollarding of selected tree species I would be able to harvest more bio-mass with rotational harvesting than I believe you would get with
yearly harvesting of Hemp ! Obviously any helpful
books on harvest size for Hemp are going to be long out of print !
After the second rotational coppicing of your hardwood the individual stout saplings will be surprisingly uniform in size and straight , cutting them and sizing them then
for loading as a Biomass to bio-gas production run
should be straight forward !
So After the gassier is up to temperature the biggest deciders on the amount of gas produced will be the amount (By weight) of material loaded and whether you are
going to stop a production run to save charcoal for an other time, or as Bio-char, or allow production run to burn the charcoal as a precursor to more Bio-gas production
I can see where something like a chopped and bailed hemp product might prove to have in its mass a perfect amount of potential
Energy as feedstock perfectly sized
for a production run scaled to a given task, and possibly a mixed load could also prove its value !
There are several members here at Permies who have experimented with woody bio-mass but you truly will be breaking new ground ! For the Crafts ! Big AL
