A fuel cell is indeed zero emission, but how the hydrogen is acquired must enter
into the calculations. Hydrogen in nature is always found combined with other
elements, it must be pulled free (not easily done) and the remaining combined
element(s) dealt with. It will be interesting to see how it plays out. There is
a segment of society that beleives these things can just be decreed and
everything else will follow.
I remember reading of hydrogen pwered cars in the 1970s. nowhere did
the story mention HOW the hydrogen was to be produced.If I remember
correctly, hydrogen was a byproduct of nuclear reactions, so it was available
from nuclear power plants. But I could be mistaken.One very large
obstacle is the infrastructure for fueling stations. think of how much money it
would take to duplicate the gas stations or to add hydrogen pumps to the current
stations.Perhaps it is not as difficult as that, but since the
article is so short on information, it's hard to fill in the gaps.One thing remarkable in the story, is these PRIVATE companies are doing this
with PRIVATE money. Since Nissan and Daimler are foreign companies and Ford did
not take bailout money, I guess BO cannot buy political favors or pay off
political debts with taxpayer money like he did with Solyndra and all his other
FAILED "green" companies.
The ironic thing is that the cheapest way to get the hydrogen is from long chain
hydrocarbons, also known as oil. However, I have heard of some people proposing
to use nuclear power plants to generate the hydrogen by running a high load
duing off-peak hours to produce hydrogen.
