what date were collected during the trial? can you say something about the methan yield per ton dry matter? an the time the hemp had to stay in the fermenter?
This was a pure trial on machinery, but we had another trial with hemp investigating the biomass and methane yield at different harvest times:
Hemp yielded about 220 m3/t dry matter (within 30 days of fermentation in a lab-scale trial). However, the trials showed that you could get out >80% of that within <10 days.
Google: "Anaerobic digestion of industrial hemp–Effect of harvest time on methane energy yield per hectare" (restricted access).
We also looked at the development of biomass yield at different harvesst dates - google: "Biomass and energy yield of industrial hemp grown for biogas
and solid fuel" (restricted access - use a university library)
Not relevant as a food crop YET. As more is learned about this plant and the fear of THC changes the food aspect will take on a whole new meaning. This plant could end starvation in so many areas around the world. Thank you for this video.
i got some hemp seed and oats cereal the other day at a place called thrifty foods. it was delish. its made by natures path. yum ill buy that shit for life.

About the char-issue I am not sure. As far as I know, this technology is still under research. I haven't heard anything about hemp being used/tested as a substrate.
The only oilhemp cultivar (Finola) approved in the EU has been taken from the list last year after THC contents above 0.2% have been found. SO, hemp is not relevant as a food crop (in the EU).
The hemp cultivars used for this cultivation (and all energy-/fiber- etc utilisations) is industrial hemp with a THC content lower than 0.2 %. In fact, only approved cultivars are allowed for cultivation and seed production, delivery as well as cultivation are subject to a strict control system. That goes for all hemp cultivation in the EU.
Hemp for biogas is less researched than other options (hemp for combustion, fibers etc), since it is cellulose-rich and therefore difficult to degrade (and use) in anaerobic fermentation (biogas production). However, new or improved pre-treatment methods help improve the convertion efficiency.
Hemp is fast growing and produces high hectare yields. Preliminary test have show that hemp can deliver around as much biogas per hectare as maize. Futhermore, hemp can be grown sucessfully further north than maize.

still having to take up valuable acreage to produce full- not so good-
billions of tons of rubbish lie in land fill waiting to be converted into biogas
