Hydrogen fuel cells may be the energy of the future, but so far the hydrogen to power them has
only been made from fossil fuels. Now, researchers at the University of Minnesota have come up
with a way to make hydrogen from a renewable fuel – ethanol, made from corn. The Great Lakes
Radio Consortium’s Stephanie Hemphill reports:
Researchers published their findings in a recent issue of Science magazine.
Lanny Schmidt is a chemical engineer at the University of Minnesota. He says his team has
created a simple system. A fuel injector forces ethanol through a catalyst. The catalyst then
converts the ethanol into hydrogen and carbon dioxide.
Schmidt says because ethanol is made from corn, it doesn’t contribute to the greenhouse effect.
“We’re now just using that ethanol as a gasoline additive. What we’re proposing here is to use
this ethanol as a transportable liquid fuel to use in fuel cells, which have two or three times the
efficiency of simple combustion.”
Schmidt says early applications could include producing electricity at remote locations like
cabins.
He’s applied for a patent, and hopes a private company will commercialize the technology.
