Zinc-Air Regenerative Fuel Cell System

Lowest cost of storage in the market for long-duration applications.

Resolves intermittent and unpredictale nature of renewable energy sources while completely decoupling the linkage between power and energy.

How Our Patented Technology Works

1

Power from the grid or renewable source is used to generate zinc particles in the Zinc Regenerator. Oxygen is released to the atmosphere as a by-product.
2

The zinc particles are flowed to the Storage Tank and maintained in potassium hydroxide (KOH) electrolyte until required.
3

Whenever power is needed, the zinc particles are delivered to the Power Stack, recombining them with oxygen to generate electricity. The zinc oxide (ZnO) by-product is returned to the storage tank for later regeneration.

Proven Competitive Advantage

Unlike lithium-ion technology, which requires new stacks in order to scale, Zinc8 has completely decoupled the linkage between energy and power. This means that scaling Zinc8's technology can be easily accomplished by simply increasing the size of the fuel tank and quantity of recharged zinc fuel.
