OK. I'll ask again again then:

For portable (eg vehicle powering)

1. What energy transport medium / technology would you
suggest to eventually replace petroleum.

2. What are its advantages over / how does it solve the
problems inherent in, using Hydrogen as an energy transport
medium?

Issues would include, but not be limited to,  end to end
efficiency, ease of energy transfer into and out of the
medium, energy density (volumetric and mass), safety, cost
(vehicular and infrastructure, both implementation and
operating), infrastructure roll out and impact, transition,
... .

The Mr Fusion unit that I saw a brief demo clip of a few
years ago, running in that instance on, AFAIR, banana skins,
seemed like it might meet most of the needs well. Anything
else seems lacking, so far.
