E-Zinc is a Canadian company that develops energy storage solutions using zinc-based technology. The company focuses on the design and implementation of long-duration energy storage systems that can support grid stability and enable the integration of renewable energy sources. E-Zinc's energy storage technology utilizes zinc as a storage medium. The system works by converting electrical energy into zinc particles, which are stored in containers. When energy is required, the zinc particles are combined with oxygen from the air, releasing electricity in the process. This approach allows for long-duration energy storage.
