About the company

e-Zinc has developed a breakthrough technology for grid-scale energy storage that stores energy in physically-free zinc metal. By decoupling power and energy, the company scales energy capacity at a fraction of the cost of lithium-ion batteries, enabling the technology to economically deliver energy over a period of multiple days. This low-cost, flexible, and long-duration energy storage solution will enable the world’s energy markets to be fully powered by renewable energy.

Founded in 2012, e-Zinc’s zinc-based energy storage system can be up to 80% less expensive than comparable lithium-ion systems for long-duration applications. Importantly, its energy storage system can operate in temperatures ranging from -30°C to 60°C, is made of abundant and recyclable materials, and is completely safe.
