The Honda CHP uses a NG-fueled engine to run a small generator whose output
offsets your grid use the same way a PV system does.  The difference is that
engine acts as a highly efficient burner to provide heat for your home or for
DHW.  The power it produces is virtually free.

No.  You have to account for the "wear & tear" of the gas engine.  A
simple gas furnace conservatively will last 7 years.   In practice it
will last 30 to 40 years.   A relatively small gas engine will wear
itself out in 24/7 service in about a year.   During that year you would
be expected to change the oil "several" times.
