Although it may not be the material of choice for electric vehicles anytime soon, the International Zinc Association is betting big on the market potential of rechargeable zinc batteries for energy storage.

The IZA has already announced the launch of its Zinc Battery Initiative (ZBI). Members of this initiative are confident in the advantage of zinc batteries’ ability to operate in a wide range of temperatures (-30 degrees Celsius to 75 degrees Celsius), as well as to provide high-power discharge and long-term storage. Unlike lithium-based alternatives, zinc batteries also have a strong safety record.

As renewables assume an even greater role in the power grid, energy storage can help address the intermittency of solar and wind power. In addition to serving as a backup supply when generation is interrupted, energy storage is also expected to play a central role in the electrification of transportation.
