Zinc8 Energy Solutions (CSE:ZAIR), founded in 2011, believes it is redefining long-duration energy storage, with its low-cost Zinc-Air battery offering a 20,000 hour operating life and over eight hours of storage.
The global rise in electricity from renewable sources has led to increased demand for advanced batteries that can be used to firm this intermittent supply.
Zinc8 Energy Solutions has developed zinc-air flow batteries as an alternative to lithium-ion batteries, which can be used in applications that require 'long duration, high-capacity' storage.
Its batteries are said to meet a need in both renewables storage and in industry and grid-scale opportunities in power acquisition and distribution. They are also a cleaner and steadier way of providing and acquiring power.
Potential uses include storing current from renewable energy sources such as wind or solar; commercial, industrial backup to replace diesel generators; industrial scale, on-demand power for peak shaving services to save grid costs; and grid-scale energy storage for energy trading.
There are three components to the system. Power from the grid or a renewable source comes into the 'zinc regenerator', where oxygen is released as a by-product. Zinc particles are then flowed to the 'storage tank' and maintained in potassium hydroxide (KOH) electrolyte until required.
