Thanks for the video. So besides the smell there is no downside to running just regular biogas as opposed to biomethane in your burners and water heater?
Biomethane is just biogas that has been refined to remove maybe two thirds of the CO2 and the hydrogen sulphide. It will burn a bit hotter than the regular biogas and will be more suitable for a direct replacement for natural gas in reticulated gas systems in towns and cities. It will have a smell added so that you can smell a leak. There is no smell from burnt biogas. The liquid fertiliser output has a bit of a smell but is not an unpleasant smell. Considering the hydrogen sulphide is a bit corrosive I wouldn't use it in a complicated system like a water heater. However you can put biogas through an activated carbon bed to remove the hydrogen sulphide and my previous bought system came with this, but i didn't find it necessary and didn't want to have to keep buying the activated carbon filters. That system also came with chlorine tablets for sterilizing the liquid output, but i found it destroyed the value of it as a fertilizer. You are unlikely to produce enough biogas to have enough to spare on top of cooking use. I have to be careful to use the biogas as efficiently as possible in order for it produce all my cooktop needs. I also have an induction cooktop for when I don't have enough biogas.
Awesome 👌🏻
Interesting.. I was thinking of trying this on a natural gas generator..
Great video , biogas to me is the best way to power ones home. Im going to build two more digesters to add to my two that i have.
