This Certainly Sounds Promising

InformationWeek: Storing solar energy in batteries remains costly and inefficient. But that may not be true for much longer.

MIT researchers have discovered a way to store solar energy that could make solar power in homes a mainstream energy option and might even make power companies obsolete, at least for residential needs.

Daniel Nocera, a professor of chemistry and energy at MIT, and post-doctoral 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. "This is the nirvana of what we've been talking about for years," Nocera told the MIT News Service.
