A cheap rechargeable battery that harnesses energy by using the electrochemistry of organic molecules rather than metals is being touted by Harvard researchers as a breakthrough for renewable energy.
"A safe and economical flow battery could play a huge role in our transition off fossil fuels to renewable electricity. I'm excited that we have a good shot at it."
According to MIT Technology review, a conventional metal-reliant flow battery costs an estimated $700 per kilowatt-hour of storage capacity, whereas the Harvard team's metal-free technology would bring those costs down to $27 per kilowatt-hour.
Sure it costs them less, but I doubt we'll see the savings.
Can this batery provide enough power to work in an electric car, it says it's cheaper but is it usable?
The U.S. target is to generate 100 gigawatts of solar power by 2020.
The researchers are working with a Connecticut-based company called Sustainable Innovations to create a portable, organic flow battery inside a unit about the size of a horse trailer.
The flow battery would be hooked to solar panels on the roof of a commercial building. The energy stored in the battery could power the building or be used whenever there's a need for it.
