The efficiency numbers look to me to be back of an envelope correct.

And that's all I guarantee them for!

I was about to do some more calculations to try to answer your
questions, and in the process of searching for numbers I found
the following Wikipedia article.

At a glance this article seems to cover a lot of the issues
being discussed. I for one would like to read it before trying
to answer. It might be worth other's to read as well.

After reading that article, I have come to the conclusion that hydrogen
as fuel will become a general economic reality only if at least one of two
things happen:

The world runs out of petroleum, natural gas, and coal and there is no
other choice.

There is huge advancement in electricity production, such as cheap
fusion.
