INTERMITTENCY OF RENEWABLES IS THE OBSTACLE

“ALL THE BATTERIES ON EARTH CAN ONLY STORE TEN

MINUTES OF THE WORLD’S ELECTRICITY NEEDS”

- Bill Gates

THE SOLUTION IS NOT SCALE

FOR GRID STORAGETHE GAME MUST BE CHANGED

STORAGE MUST BE CHEAP

GREEN, SAFE, CIRCULAR, &MADE OF ABUNDANT MATERIALS

THE AZA ZINC AIR BATTERY CHEAPER - SAFER - GREENER

The AZA Battery is made from zinc and air

AZA BATTERY: PASTED ZINC ELECTRODEprismatic shape (not flow) – high energy density

ZINC AIR STORAGE IS CHEAPER

AZA will achieve a 40% CHEAPER LCOE

(levelized cost of stabilized electricity) vs. lithium

For 2030 solar farm applications

expected price drop from $ cents 9.1 per kWh (using Lithium batteries in 2020) to $ cents 3.3 per kWh (using Zinc-air batteries in 2030) and assumes a steady

drop in the price of Lithium batteries and Solar panels

ZINC IS SAFER

ZINC IS GREENERLithium mining and processing creates permanent environmental

damage through toxic exposed tailings and residual salts

ZINC IS RECYCLABLE

zinc recycling is a process that is well established world-wide

many governments prioritize ”circular economies” with recyclable inputs

cost-effective large format lithium battery recycling is non-existent

Global lithium reserves: 62,000,000 tonsGlobal zinc reserves: 1,900,000,000 tons

AZA BATTERIES ARE MADE FROM ABUNDANT MATERIALS

zinc reserves are distributed worldwide; only a handful of countries have battery-grade lithium reserves

Developing standardized containerized and cabinet solutions and customized to specific needs/applications

First applications will be Solar Farms and Large Commercial ( > 1 MWh)

Safety and low capex intensity favors bankability and insurability of Zinc-Air

Actively developing pilot relationships with customers and partners

AZA BATTERIES ARE NOT AVAILABLE YET BUT...

6h to 12h storage allows solar farms to provide the grid with stable power all day long

Full solar based autonomy for off-grid becomes energy competitive with on-grid

PV + storage becomes the alternative electricity provider
