Not that NG (despite your comfort with it) is hazard free...
The big ones: No smell or wrong smell (cow-manure-is or sewerish rather than "GAS LEAK!")
Oh man, who farted, that's awful, let's light a candle...FOOM!
Possibility of the gas generated being mixed with oxygen/air in a small digester system especially whenever started up or opened to feed - which means the gas lines could have a flammable mixture in them rather than pure gas, which won't ignite inside the pipes.
Smaller issues: troubles with inconsistent or wet gas ruining your NG appliances.
Troubles with sue-happy readers - the "don't try this at home, folks" approach. By the way, don't try this at home
Also, kiss your house insurance goodbye, probably. The gas company is a known entity that works to a certain standard. Insurance companies are OK wih that standard. Homebrew gas system connected to the house will probably get your coverage voided even if it has nothing to do with any claim you need to make (or if the insurance company finds out about it they may cancel you before you need to make a claim.)
...aaaand finally, I wonder if you are confusing biogas (methane, digester gas) with "biomass gasification" gasifier, wood-gas, producer gas which IS one of those "much more dangerous" gasses, as it has a lot of carbon monoxide, which makes it phenomenally dangerous indoors as compared to methane/natural gas.
Ray Cover wrote:That makes sense and you may be correct I may be getting my gasses mixed up. That is very possible. I thought that gas made form a wood or biomas gassifier was called syngas and that methane was made out of garbage/biomass in a digester. This is new ground for me. I very well may have my wires crossed.
