In fact, if one wanted to build a low-emission truck
the use of methane, either compressed or liquefied, makes
a great deal of sense. That tech is already commercial.
And, methane is cheap.

Methane is the best bridge fuel we have access to in quantities
and at a cost that isn't hugely disruptive.

And yet it is inferior to electricity as a heating source?

 
Electricity isn't a source, it's a transmission medium,
same as hydrogen.
 
Perhaps I'm missing your point, if so please elaborate.

The energy content of methane / natural gas is  1/2 to 2/3 wasted when
generating electricity, while burning gas in a condensing home furnace
wastes only 10% of the higher (steam condensing) heat value.

Not sure what you're driving at. The COP of a heat pump in a warm
climate (like Britain) can overcome the losses inherent in generation.
Not always, and certainly not everywhere.

Use of a bottoming cycle gas turbine/steam generating plant helps a lot.
