UNC Researchers Convert Solar Energy Into Fuel

The new system generates fuel by using the sun's energy to split water into its component parts - storing hydrogen, releasing oxygen.

The Frontier Research Center at UNC-Chapel Hill has built a system that converts solar energy into fuel, so power can be used even after the sun sets.  The US Department of Energy is funding the research.

Instead of storing solar electricity in an expensive battery, researchers use the sun's energy to separate water into hydrogen and oxygen.  Two of the Center's papers about the process were recently published in the Proceedings of the National Academy of Sciences.
