Solar cell directly splits water for hydrogen
February 19, 2008 | Filed Under hydrogen
Plants trees and algae do it. Even some bacteria and moss do it, but scientists have had a difficult time developing methods to turn sunlight into useful fuel. Now, Penn State researchers have a proof-of-concept device that can split water and produce recoverable hydrogen.
“This is a proof-of-concept system that is very inefficient. But ultimately, catalytic systems with 10 to 15 percent solar conversion efficiency might be achievable,” says Thomas E. Mallouk, the DuPont Professor of Materials Chemistry and Physics. “If this could be realized, water photolysis would provide a clean source of hydrogen fuel from water and sunlight.”
It’s not a silver bullet for all of mankind’s energy problems, but it had to happen, right? Use this link for the full press release
