An “affordable” flow battery technology

An “affordable” flow battery technology is currently under development by researchers at Ann Arbor–based Vinazene Inc, in partnership with Grand Valley State University’s Michigan Alternative and Renewable Energy Center and its Chemistry Department.

The new project — which is funded by a DOE Phase II Small Business Innovation Research grant — is based around the use of proprietary, high-capacity organic electrolytes. The use of these organic electrolytes, rather than relatively expensive metals like vanadium, is what will reportedly allow for greater “affordability” — to date, the barrier to wide-scale use of flow battery technologies has been their relatively high costs.vAnother purported advantage of the use of these proprietary organic electrolytes is the ability to specifically tailor the compounds used for higher solubility (amongst other traits). The Vinazene battery will reportedly have a higher energy density than the more well known vanadium-based systems, owing to this higher solubility.

Based on Vinazene’s website, the researchers involved seem pretty bullish on the technology — but then they often do, don’t they? Still, it sounds like there’s potential there. Perhaps something will come of it.

The researchers mention possible uses in remote military. surveillance, and/or telecommunication sites. Other potential uses include those in greenhouse farming and various types of industrial production facilities.
