The Harvard approach utilizes the electrochemistry of quinones, organic molecules that are similar to molecules that store energy in plants and animals and are plentiful in crude oil and green plants. Using these naturally abundant and inexpensive organic molecules, the researchers have developed a metal-free flow battery that already performs as well as vanadium flow batteries, while using significantly less expensive chemicals and no precious metals.
Previous membraneless systems have been largely unpractical, but the scaled-up version of the device could have a substantial real-word impact because it could be used to produce energy for a very competitive US$100 per kilowatt-hour. “Most systems are easily an order of magnitude higher, and no one’s ever built anything at that price,” says William Braff, who was part of the research team.
The room also contains a 5-kilowatt battery – which will sell for between $10,000 and $20,000
