CUNY Energy Institute Batteries Power Off-Grid Booth

March 2, 2012 | News

At this year’s Energy Innovation Summit, the CUNY Energy Institute showed off the power of our zinc anode rechargeable batteries with an exciting off-grid demonstration. A bike training system connected to our batteries provided the power for a set of LED lights and a monitor. Riders could watch as their peddling charged the batteries at our off grid booth. The competition got intense as members of the CUNY Energy Institute and the Department of Energy faced off to see who could charge our batteries the most quickly.

Researcher Josh Gallaway charges CUNY Energy Institute batteries and powers LED lights by riding bicycle.

The CUNY Energy Institute has been a leader in developing innovative low-cost batteries for grid-scale applications. Our batteries are safe, non-toxic, and reliable with fast discharge rates and high energy densities. For the same cost as lead acid batteries, our Ni-­Zn batteries have ten times the cycle life. We have proved 3000 cycles and counting and plan to have a 50kWh system installed at our City College of New York headquarters by mid-2012. Our next generation Zn-­MnO2 batteries will further reduce cost while maintaining cycle life. Watch CUNY Energy Institute director Sanjoy Banerjee in this video for more information!

Energy storage is needed to reduce energy demand in urban areas, power buildings, secure the electric grid, and enable the increasing use of intermittent renewables. The Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) has provided critical support for grid-scale energy storage through the GRIDS program.
