Solar Water Splitting

Researchers have created a floating, solar-powered device that converts contaminated water or seawater into clean hydrogen fuel and drinking water. Because it works with any open water source, it could be used in resource-limited or remote places.

​​Using the power of the sun to split water and produce hydrogen fuel is one of the most promising clean energy technologies being pursued. Now researchers at the University of Exeter have created a semiconductor material that should help make it viable.

Researchers have demonstrated a one-step conversion of carbon dioxide and water directly into a simple and inexpensive liquid hydrocarbon fuel using a combination of high-intensity light, concentrated heat, and high pressure.

Researchers at Monash University claim to have created a solar-powered device that splits water to produce hydrogen at a world-record 22 percent efficiency, which is a significant step towards making cheap, efficient hydrogen production a reality.
