In Indiana they were using the methane primarily for heat. However, they also captured it and would set up a supply for their standby generator, too.
Because methane has such a lousy BTU content, like 500-600 BTU/CF, compared to natural gas (800-900 BTU/cf) and propane (1100 BTU/cf) you would have to oversize the generator to a factor of easily 2x or more, meaning you paid a lot more in capital to get the same thing. Add to that the driers, etc., that were necessary to process the fuel to make it viable as a motor fuel and you had even more money tied up in it. Sure, the fuel was free, but you had to lay out a lot more money to use it. And as I mentioned previously, it was hell on the equipment. Some of the landfills were doing it, too, but years later you could see that they gave up and were just flaring the stuff. -D > On Aug 22, 2019, at 9:22 PM, Clay Monroe via Mercedes <mercedes@okiebenz.com> > wrote: > > IIRC, Tina Turner had a hog digester to run her ThunderDome way back in the > ’80’s.
