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