Bush Hydrogen/Solar (was Real Industry) [RE-wrenches]

Joel noted:

"President Bush released his proposed fiscal year 2004 federal budget
Monday, which revealed increased spending for hydrogen technology
research - a point he emphasized in his State of the Union Speech -
while slashing funding for Solar Energy research by US$15 million to
US$80 million."

When I heard the state of the union, I was concerned about this very 
issue.  He talked about hydrogen as a clean energy source, that would 
lessen America's dependence on foreign supply.

Where does Mr. Bush plan to get the hydrogen?

Hydrogen is not a source of energy, it is an energy delivery strategy. 
There are not reserves of hydrogen.  It must be created from hydrogen 
rich substances (including H2O), which requires energy.

The cleanest way to produce hydrogen is from solar.  The administration 
is likely to push coal, nuclear.

from the introduction:

"Hydrogen is a fascinating carrier of energy. Its conversion to heat or 
power is simple and clean. When combusted with oxygen hydrogen forms 
water. No pollutants are generated or emitted. The water is returned to 
nature where it originally came from. But hydrogen, the most common 
chemical element on the planet, does not exist in nature in its pure 
form. It has to be generated or irproducedln by separating it from 
chemical compounds. Hydrogen can be produced from water by electrolysis, 
from hydrocarbon fuels by reforming or thermal cracking, or from other 
hydrogen carriers by chemical processes. But clean energies such as 
electricity from solar, wind and hydro must be applied to produce clean 
hydrogen, i.e. without greenhouse gases or nuclear waste being
generated in the production process. Hydrogen may actually be the only
meaningful link between renewable energy and chemical energy carriers."
