Zinc8 Energy Solutions Inc. announced that the Zinc8 ESS is a modular Energy Storage System designed to deliver power in the range 20kW - 50MW with capacity of 8 hours of storage duration or higher. With the advantage of rechargeable zinc-air flow battery technology, the system can be configured to support a wide range of long-duration applications for microgrids and utilities. Since the energy storage capacity of the system is determined only by the size of the zinc storage tank, a very cost-effective and scalable solution now exists as an alternative to the fixed power/energy ratio of the lithium ion battery. The Zinc8 ESS is based upon unique patented zinc-air battery technology. Energy is stored in the form of zinc particles, similar in size to grains of sand. When the system is delivering power, the zinc particles are combined with oxygen drawn from the surrounding air. When the system is recharging, zinc particles are regenerated, and oxygen is returned to the surrounding air. The flexibility of the Zinc8 ESS enables it to service a wide range of applications. Typical examples include: Smoothing energy derived from renewable sources such as wind and solar; Commercial/Industrial backup replacing diesel generators; Industrial and grid scale, on-demand power for peak shaving and standby reserves; Grid-scale services such as alleviating grid congestion, deferring transmission/distribution upgrades, energy trading and arbitrage, and increasing renewable energy penetration. The Zinc8 ESS is designed according to a modular architecture that enables a wide variety of system configurations to be created from a small number of common subsystems. Each subsystem implements a single element of the technology: The Zinc Regeneration Subsystem (ZRS) provides the recharging function; The Fuel Storage Subsystem (FSS) provides the energy storage function; The Power Generation Subsystem (PGS) provides the discharging function.
