    Hydrogen fuel edges a step closer

    Chemical setup creates clean-burning gas

    By Rachel Ehrenberg

    Web edition: November 8, 2012

    Making hydrogen gas in water just got a little easier. The discovery may lead to inexpensive, practical means of harvesting sunlight to create clean-burning hydrogen for powering cars or generating electricity.

    Scientists would like to mimic plant photosynthesis, which harvests sunlight and splits water molecules to create fuel. It sounds simple, but even in plants the task is a highly orchestrated set of reactions, with multiple players acting in multiple places. So researchers often tackle one half of photosynthesis at a time.

    The new study, published online November 8 in Science, focuses on the light-harvesting side of the equation. The researchers, from the University of Rochester in New York, created tiny particles of cadmium and selenium that spit out electrons when hit with light. The team also needed a catalyst to pass those electrons to hydrogen molecules, which would combine into the useful gas H2.

    This is interesting news. Now if there was a better way of storing it in a motor vehicle.
    "The blood-dimmed tide is loosed, and everywhere the ceremony of innocence is drowned;
    The best lack all conviction, while the worst are full of passionate intensity. "

    W.B. Yeats- 1919
