Doesn't NG have some small percentage of ethane, propane and butane
mixed in as well? This would presumably increase the energy desnity over
straight methane.
Also, while I think of it, isn't biogas closer to a 50:50 mix of methane
and CO2, with, as you say, some trace impurities? Reason I ask I that i
thought you had to remove the CO2 before you can use biogas in a natural
gas appliance.

Natural Gas = methane + Odorant;
Bio methane just methane + some CO2 and impurities from the
decomposition process.
So any NG appliance will run on Bio Decomposed methane.
Its just that is very difficult to liquefy NG (-200C like temps).

As I understand it, methane (which can be produced from rotting
waste) can be burned in most propane appliances with the appropriate
slight modifications.
Is propane a "Bio" fuel, can it be created from "bio" sources?
