Bacteria turn excess clean energy into methane for storage

Penn State researchers have found a possible solution to the problem of storing alternative energy. It's a bacterium able to convert electricity into methane gas when combined with CO2.

The Cleantechnica blog reports that: "Any surplus power from wind, solar, or tidal sources is fed into thebacteria and combined with CO2 from the atmosphere to create methanefor storage. Methane is a clean-burning gas and 80% of energy fed intothe process was retained at the end."

Might this also deal with some excess CO2?
