Zinc8 Energy Solutions announced it has signed an agreement to install a 100-kilowatt (kw), 1.5-megawatt-hour (MWh) zinc-air energy storage system in Brooklyn, New York.
Zinc-air energy storage is a three-part system that stores energy from renewable and other sources and then delivers electricity to the grid as needed.
Basically, energy is stored in the form of zinc particles that are roughly the size to grains of sand.
- When the system is delivering power, the zinc particles are combined with oxygen drawn from the surrounding air.
- The zinc oxide produced is stored in storage tanks containing a potassium hydroxide electrolyte.
- When the system is recharging, zinc particles are regenerated, and oxygen is returned to the surrounding air.
This groundbreaking energy storage solution won the New York Power Authority (NYPA) Innovation Challenge, which is resulting in Zinc8's first 100 kw, 1.5 MWh zinc-air energy storage system installation in New York State.
