How do they make the bio gas into sellable fuel?
In the united states bio gas is almost always made and burned on site to fire a boiler at an industrial plant.

In the United States the only place I have seen a meaningful number of CNG pumps is in Texas. With natural gas prices being low right now, CNG probably costs 2/3 to 3/4 the price of gasoline.
If you had a home fill station, it would cost almost nothing to fill up.
11kg is a lot, I had to assume that a car would probably hold around 5 to no more than 8kg.
When I was looking at CNG a few years ago the information was as hard to find as fill stations.
1984 chevy suburban, custom made 6.5L diesel turbocharged with a Garrett T76 and Holset HE351VE, 22:1 compression 13psi of intercooled boost.
1989 firebird mostly stock. Aside from the 6-speed manual trans, corvette gen 5 front brakes, 1LE drive shaft, 4th Gen disc brake fbody rear end.
2011 leaf SL, white, portable 240v CHAdeMO, trailer hitch, new batt as of 2014.
