About the Company

Founded in 2012, e-Zinc is a Toronto-based corporation that has developed a breakthrough electrochemical technology for storing energy in zinc metal. This low-cost, flexible, and long-duration energy storage solution will provide the platform for the world’s energy markets to be fully powered by renewable energy, enabling a zero-carbon energy future.

About the Solution

e-Zinc’s technology is a paradigm shift in energy storage. By storing electrical energy within zinc metal, the system can store hundreds of hours of energy capacity while being significantly cheaper than battery technologies.

e-Zinc’s technology decouples power from energy, allowing low-cost scaling of storage capacity based on three principles:

1. Zinc metal, which has a high energy density and is inexpensive, is used as the energy carrier.

2. The zinc metal is detached from electrodes allowing the metal to be stored independently at a low cost, unlike rechargeable batteries in which the energy-bearing metal is fixed on the electrodes.

3. The storage space is located within the same electrochemical cell as the charging and discharging electrodes, enabling a simple operation.
