Long-lasting flow battery could run for more than a decade with minimum upkeep Battery stores energy in nontoxic, noncorrosive aqueous solutions By Leah Burrows February 9, 2017 Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new flow battery that stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production. https://www.seas.harvard.edu/news/2...-run-for-more-than-decade-with-minimum-upkeep
With assistance from Harvard’s Office of Technology Development (OTD), the researchers are working with several companies to scale up the technology for industrial applications and to optimize the interactions between the membrane and the electrolyte. Harvard OTD has filed a portfolio of pending patents on innovations in flow battery technology Anyone know who those 'several companies' are? Thanks.
There is a lot more vanadium which is used in the (current) redox-flow batteries than lithium, estimated 8x in the Earth's crust.
It's not going to be small and the energy density is likely going to wayyyy below that of a Lithium battery, so zero use in a car sadly, could charge over the day from Solar then charge the car over night ofcourse.
Flow batteries were originally designed for utility class energy storage. MW-hours. Interesting concepts. Energy Storage at all in market competitive rates is the holy grail for non-baseload alt energy viability. Price to performance w/o govt subsidy is the real hurdle IMHO. T
