A new catalyst makes it feasible to split water with solar power.
MIT chemists say the catalyst, used in conjunction with cheap photovoltaic solar panels, could lead to inexpensive, simple systems that use water to store the energy from sunlight.
In the process, the scientists may have cleared the major roadblock on the long road to fossil fuel independence: Reducing the on-again, off-again nature of many renewable power sources.
The catalyst enables the electrolysis system to function efficiently at room temperature and at ordinary pressure. Like a reverse fuel cell, it splits water into oxygen and hydrogen. By recombining the molecules with a standard fuel cell, the O2 and H2 could then be used to generate energy on demand.
"You've made your house into a fuel station," Daniel Nocera, a chemistry professor at MIT said. "I've gotten rid of all the goddamn grids."

Pretty cool professor, good work on those "goddamn grids."
