Hydrogen, again …
I was encouraged to keep surfing, and to find better well-to-wheels (WTW) comparisons between natural gas vehicles and hydrogen vehicles (when using hydrogen reformed from natural gas).
Without returning to the “boondoggle” discussions, I’ll just say that I’m satisfied for now that natural gas cars hold their own from an efficiency standpoint.
The most complete WTW table I’ve found is from the International Association for Natural Gas Vehicles (IANGV):
The complete PDF is available here. This table appears in section 8.3 on page 93.
I do, of course, look forward to hydrogen fuel cell vehicles powered by green (non-petrolium) hydrogen sources.
