AFAIK, no current US systems use anything but methane or a mixture of
methane and a small amount of ethane (which occurs naturally). Bottled
gas uses propane. Town gas (water gas, producer gas, etc. AKA H+CO) is
pretty much extinct.

Using hydrogen directly would be both uneconomical and unsafe. Better
to simpy use hydrogen and any convenient carbon source (garbage, ***,
coal, cottonseed hulls, wood shavings, etc.) to produce methane and
keep the existing piping network.

This is one of the fallacies of the hydrogen economy crowd. The
simplest thing to do if you find a way to make a lot of hydrogen
cheaply, is to use it and a recyclable carbon source and make methane,
gasoline, or diesel fuel. The combination has almost no environmental
impact.
