AFRICA’S RENEWABLE ENERGY INFRASTRUCTURE POTENTIALAt ESS Inc., we understand that project developers, utilities, and governments are re-examining
the role of energy storage throughout Africa. As the need for more flexible heat tolerant energy
storage increases, ESS Inc. provides superior cycle life, increased safety, and environmentally
sustainable solutions. As Power Africa’s only flow battery partner, we are committed to deploying
our long-duration energy storage solutions for microgrid and utility-scale projects throughout the
continent to help Power Africa achieve its goals of bringing 30,000 MW of new and cleaner power
generation online, and delivering 60 million new electricity connections.
We are the only energy storage platform that offers a comprehensive 10-year insurance policy that
cover’s our product’s performance. Backed by Munich Re, the world’s leader in the development
of new insurance solutions for climate-friendly technologies, this policy provides our customers
with a long-term performance guarantee.

Principles of iron fl ow battery chemistryOur battery is powered by simple electrochemistry, comprised of earth-abundant iron, salt, and water. The system’s
environmentally benign characteristics, containing no hazardous chemicals or rare-earth metals, make it the
easiest-to-permit storage technology in the world. The iron fl ow battery has no fi re, chemical, or explosive risk,
eliminating the need for fi re-suppression, secondary containment, and hazmat requirements. Systems can be easily
refurbished to extend life additional 20+ years or fully recycled at end of life.

Low-cost abundant electrolyte material
With the same electrolyte running on both the negative and positive sides of the
membrane, there is no cross contamination.
6 REASONS TO CONSIDER THE ENERGY WAREHOUSE™ AND ENERGY CENTER™1. Unlimited cycling: Our batteries can be operated under any duty cycle requirements without
limitation and no degradation in performance.
2. Bring the heat: Our batteries operate from 5° to 50°C without the need for A/C.
3. Lowest cost of service: Our batteries have the lowest overall cost of service for long-duration
or multi-cycling requirements, especially so in “workhorse”, heavy use applications.
4. Long-life asset: Our energy storage system has a design life of 25 years.
5. No hazardous materials, no fire risk or explosion risk: Our batteries use no hazardous materials,
which means no hazmat training, no hazmat suits, no hazardous chemicals disposal plan, and
easy permitting.
6. Warranty backed by Munich Re: Our power module warranty is the only one in the world backed
by an investment-grade insurer. Expect nothing less for your energy storage investment.
Hazard-free energy storage
Our electrolyte and module were tested to nearly 14,000 cycles with no loss of performance.
Subsequent analysis confirmed no corrosion, no loss of material, no mechanical deformation
issues. Tests conducted under the Advanced Research Projects Agency-Energy program.
