Powering cars from alcohol to hydrogen
Anna Salleh
ABC Science Online Monday, 16 February 2004

Hydrogen-powered cars could be one step closer following the
development of a new compact reactor that produces hydrogen from a
renewable energy source, according to new U.S. research.

Gregg Deluga and fellow chemical engineers from the University of
Minnesota report how they generated hydrogen from alcohol in the
current issue of the journal Science.

"This process has great potential for low-cost H2 generation in fuel
cells for small portable applications where liquid fuel storage is
essential and where systems must be small, simple, and robust," the
researchers wrote.

Efficient production of hydrogen gas from renewable resources is one
of the key factors holding back the much mooted green 'hydrogen
economy', which includes cars running on hydrogen fuel cells.

Ethanol, an alcohol derived from grain like corn, has been one of
the renewable hydrogen sources researchers have explored. It is easy
to transport, relatively non-toxic and some vehicle engines already
burn it directly.

But Deluga's team used ethanol indirectly, to produce hydrogen for a
fuel cell the researchers said would be three times as efficient as
..............................................................burning ethanol directly.
