New Oxygen-Hydrogen Battery Could Be Key to Storing Solar Energy

Researchers have come up with a cheap and easy process for storing solar energy, in a finding that could provide one of the final elements for efficient solar power systems: the ability to store excess energy in a battery for use later when the sun isn't shining. Researchers are euphoric about their invention, which could mark a great leap forward in solar technology; previous experimental batteries used to store solar energy have been bulky, expensive and inefficient.
