NREL: News Feature - Sun Shines on Old Idea to Make Hydrogen

Back in 1998, when gasoline prices were $1.03 per gallon, John Turner of the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) dropped jaws all over the energy world by demonstrating that he could use sunlight to extract hydrogen from water at a remarkable 12.4% efficiency.

Three hundred articles and news reports followed, there were predictions of the next big thing, and then … almost nothing happened.

Energy companies went back to their gasoline and their diesel, or their attempts to extract fuel from biofuels, or to extract hydrogen via algae or coal-powered electricity.

Now, with gasoline at $3.89 per gallon, and still the dominant transportation fuel, there is renewed interest in Turner's work.
