| Whatever! You echo the insanity of the crowd which also denies that H2
is a fuel.
The two primary methods for releasing the energy of H2 is either
combustion or chemical conversion. Combustion is inefficient, but it
works (our cars prove that every day). In fact, Arnold Schwarzeneger,
Governer of Californer, converted one of his Hummers to run on H2.
Now, chemical conversion has no limit on efficiency (unlike the Otto
cycle used in automobiles). It drives an electric engine. Again,
power is created and what is the fuel? Hydrogen, of course.
So where is the pollution? The reaction goes like this: hydrogen plus
oxygen yields water. That's it! Other reactions only accompany
impurities. The typical pollutants: COx, NOx, SOx all require
combustion in the presence of other elements like carbon, nitrogen and
sulfur. Therefore, it is true that with combustion, impurities
pollute. Every known hazardous chemical requires other ingredients in
addition to H and O.
Pollution from impurities is negligible to non-existent, unless you
consider the following idiotic recipe: Heat lots of coal (an extremely
dirty rock) to insane temperatures in a container and extract the
hydrogen and impurities (S, Hg, N2, etc). Next, WITHOUT purifying the
gaseous mixture, feed it directly into an internal combustion engine
and combust it. Now, with the application of many levels of stupidity,
you can have your pollution. It takes an active effort to make it seem
like hydrogen pollutes, but in the end everyone knows that H2 means two
hydrogen atoms. But why listen to a stupid activist freak?
Though alternative fuels are good ideas, hydrogen is NOT the same as
alchohol or biofuels, etc. The pollution associated with biofuels has
nothing to do with hydrogen. Coal-derived hydrogen is impure, but we
have methods for purifying it; a topic completely ignored by activist
freaks against hydrogen. Why not talk about the traditional (and
clean) methods for creating hydrogen: electrolysis and the water-gas
shift? Why not talk about the use of nuclear plants for meeting our
energy needs and reducing the costs of our fuels?
