Solar hydrogen – Energy of the Future

A team of Australian scientists predicts 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.

Using special titanium oxide ceramics that harvest sunlight and split water to produce hydrogen fuel, the researchers say it will then be a simple engineering exercise to make an energy-harvesting device with no moving parts and emitting no greenhouse gases or pollutants.

It would be the cheapest, cleanest and most abundant energy source ever developed: the main by-products would be oxygen and water. Rooftop panels placed on 1.6 million houses, for example, could supply Australia’s entire energy needs.

“This is potentially huge, with a market the size of all the existing markets for coal, oil and gas combined,” says Professor Janusz Nowotny, who with Professor Chris Sorrell is leading a solar hydrogen research project at the University of NSW Centre for Materials and Energy Conversion. The team is thought to be the most advanced in developing the cheap, light-sensitive materials that will be the basis of the technology.
