<VV> methanol vs. ethanol

[jvhroberts at aol.com]

 You forgot to mention that NG is the second most important feedstock for oil refineries. It's THE hydrogen source for converting crude to the lighter (and far more hydrogenated) distillates that come out, like gasoline, diesel, kerosene, propane, etc.
