Turning Buildings into Batteries
Chicago-based Clean Urban Energy uses the thermal properties of buildings’ mass to store cooling energy during off-peak, unoccupied hours when electricity prices are low. The stored cool is released throughout the day, reducing energy consumption during peak times.

Biking for Batteries
CUNY's Josh Galloway shows how the bike is able to charge their flow-assisted alkaline battery. The CUNY Energy Institute aims to demonstrate a better cycle life than lithium-ion batteries, which can be up to 20 times more expensive than Zinc-based batteries.

CUNY's Energy Storage Solution
The nation's current electric grid has limited ability to store excess energy, so electricity must constantly be generated to match demand. If successful, CUNY Energy Institute’s flow assisted alkaline battery project would put the U.S. on a path towards creating a smarter grid with low-cost batteries that are capable of storing enough electricity to power homes, cars and cities.

UMD's Thermoelastic Cooling
Researchers at the University of Maryland are developing an energy-efficient cooling system that eliminates the need for synthetic refrigerants that harm the environment. Using thermoelastic cooling systems, UMD is developing and testing shape memory alloys and a cooling device that alternately absorbs or creates heat in much the same way as a vapor compression system, but with significantly less energy and a smaller operational footprint.
