Solar Storage

MIT researchers have developed a new method for solar storage that splits “water into hydrogen and oxygen gases using the sun’s energy — recombined later inside a fuel cell.” Video after the break.

The key components to the process are a pair of catalysts (one consists of cobalt metal, phosphate, and an electrode; the other, platinum) which produce the O and H gases at room temperature and in neutral pH water (i.e., tap water).
