Australian Scientists Predict Hydrogen Fuel To Become Reality

SYDNEY, NSW - MAY 18: Leigh Sheppard, a PHD student in Ceramic Engineering at the University of New South Wales (UNSW) views a tiO2 photo-electrode used in an experiment to produce hydrogen from water and light May 18, 2005 in Sydney Australia. The University's Centre for Materials Research in Energy Conversion has developed a method to generate hydrogen from water using solar power and a catalyst of titanium dioxide. The process converts sunlight to electricity, which is then used to separate water into oxygen and hydrogen. Scientists working on the project at UNSW predict that a revolutionary new way to harness the power of the sun to extract clean and almost unlimited energy supplies from water will be a reality within seven years.
