MIT chemist turns to nature to solve solar energy problem
The power of solar is not on the grand scale of collectors spread over square acres in the west desert, says Daniel Nocera, a widely cited chemist at the Massachusetts Institute of Technology who is scheduled to speak at Utah State University this week.
"Each household could be its own little power station," Nocera said Sunday.
Using the principle of photosynthesis and more precisely duplicating the storage process that plants use to stay healthy at night when they're not being fed directly by the sun, Nocera's research published this past July appears to have answered the abiding problem with solar power the daily interruption of power at night.
"By finding a way to mimic what all those leafy things out there called weeds do at night for energy, we can provide the electrical needs of the house and the family car, and it can be done at room temperature and very inexpensively."
Nocera, who is the Henry Dreyfus Professor of Energy at MIT, became known globally this summer when he and colleague Matthew Kanan made the breakthrough discovery of a highly efficient technique for electrolysis of water using inexpensive materials.
The ultimate goal isn't just to make electrolysis more efficient, but to induce all the functions needed for artificial photosynthesis: Instead of the power coming from the solar panels, energy would be captured directly by a photochemical process and transferred directly to the electrocatalyst process.
By splitting water into hydrogen and oxygen then recombining them to create energy, the pair overcame the impractical nature of hydrogen as an electrical power storage medium. Between 30 and 50 percent of the energy is lost under conventional electrolysis methods.
His approach was novel but based on Nocera's previous research in condensed matter physics.
The main hitch of solar, wind and ocean waves is not the capacity to to generate enough energy or economics but the lack of an efficient and low-cost method of storing it.
Right when the sun goes down is right when a household's power needs go up. So without some way of storing enough power for those load requirements and without a method of tapping it that didn't take half the energy available, the research has been stuck.
