May 6, 2009 -- In what may be the ultimate bid for clean energy, a NASA-backed group is designing a wind- and sun-powered fueling system for city buses -- and possibly other machines -- that run on hydrogen.
The demonstration is intended to not only showcase a fuel with zero carbon emissions, but to produce the hydrogen in similar fashion.
The project, spearheaded by NASA's Glenn Research Center in Cleveland, Ohio, would use power produced by a windmill and solar energy cells to run a machine called an electrolyzer that splits water molecules into its base elements of hydrogen and oxygen. The hydrogen, in turn, would be used as fuel for specially-equipped buses.
"What we're proposing is to give a full-scale demonstration of taking renewable energy off of a wind machine or photovoltaic grid, using that energy to power a water electrolyzer to break down water into hydrogen and oxygen and then use that hydrogen as a fuel in a fuel cell-powered vehicle," Paul Prokopius, an energy consultant and retired NASA fuel cell researcher, told Discovery News.
