  •  Several problems with Hydrogen (0+ / 0-)

    As I see it:

    1) Hydrogen suitable for distribution as a fuel storage has to be produced. That takes energy. Might be able to do it greenly e.g. solar/electrolysis but large scale producers may use dirtier methods.

    2) Hydrogen is "unstable" and requires extraordinary safety measures.  I would conclude that the technology to store it safely in a moving vehicle would not be available for many decades.

    3) There is no existing infrastructure for distributing hydrogen compared to other fuel choices.  (e.g. electricity, Natural gas)
    Building an infrastructure of comparable mass will take decades and cost trillions.

    One of the schemes I've seen for creating Hydrogen is to utilize Natural Gas and convert it onsite at a filling station. I conclude it would make more sense to use CNG in a vehicle and a fuel cell to catalyze it.  

    I think electricity and efficiency are our future.  Most daily car trips are less than 40 miles, well within the range of battery technology today.  Wind and solar are actually radically pushing down the cost of electricity.  New prospective technologies on the horizon include Traveling Wave Reactors which promise to convert our huge stockpiles of depleted uranium into clean long running supplies of power on industrial power plant scale.
