Are Solar Batteries On The Way Out?

 

Will storing solar energy in batteries soon become obsolete? Major environmental scientists think that it's only a matter of time.
 
Daniel Nocera, a professor of chemistry and energy at MIT, and postdoctoral fellow Matthew Kanan have figured out how to split water into hydrogen and oxygen cheaply and efficiently at room temperature. The process can later be reversed, allowing the recombination of hydrogen and oxygen in a fuel cell to create carbon-free electricity. 
 
 
Nocera told the MIT News Service that within 10 years, he expects that homeowners will be able to use solar power to provide electricity during the day and to store unused solar energy to power a household fuel cell for evening use. This would eliminate the need for electricity delivered over power lines.
