Avalon Battery

Technology

RELIABLE AND SIMPLE CHEMISTRY PROVIDES ROBUST, STRAIGHTFORWARD OPERATION THAT REDUCES RISK OF DOWNTIME.

Avalon’s products employ time-proven, globally-deployed Vanadium Redox Flow Battery (or “VRFB”) technology to deliver reliable, economical power. VRFB technology has been in the global market for decades. Avalon’s approach is novel in that we employ patented materials and a fully-integrated turn-key product architecture. These technologies allow our products to achieve exceptional levels of reliability at very low cost.

OUR PROPRIETARY TECHNOLOGY DELIVERS Unprecedented SAFETY AND STABILITY

Inherent to Avalon’s VRFB technology is the stability of the vanadium chemistry itself. Unlike technologies that rely on different elements to make up the positive and negative cells of the battery, VRFBs use vanadium as both the positive and negative “couple”. This means that the technology cannot become contaminated and degrade over time.

Similarly, because the vanadium is dissolved in a stable, water-based solution, the risk of fires are dramatically mitigated in the VRFB. Avalon has worked with leading fire safety experts to assess the risk of a fire in or near our products. The results of that assessment: That our products are substantially safer to operating personnel and first responders, as compared with other battery technologies.

Finally, Avalon’s VRFB is shipped to site in a 100% complete turn-key configuration – a first for the flow battery industry. That means that every battery we ship, to every customer, has been built, tested and certified to stringent quality standards before it leaves the factory. This yields faster installation, lower commissioning costs and far more reliable performance in service.

DELIVERS LOW COST AND LONG LIFE

In operation, the durability of Avalon’s products mean decades of dependable performance with low maintenance and zero augmentation. Avoiding those costs over the life of the product, combined with a low initial capital investment, means those products’ levelized cost of storage (or “LCOS”) is 0.08 USD/kWh today, and is expected to be below 0.03 USD/kWh by 2025. Deploying lithium ion batteries to deliver that same performance is far more expensive: 61% more expensive today, and over 230% more expensive by 2025.

Avalon has proven that its products deliver dependable performance, at scale and in the field, by executing the equivalent of over 20 years of charge and discharge cycling in extremely demanding duty cycles and operating environments. Over the decades to come, our customers will reap the benefits of being able to execute more than 20,000 charge and discharge cycles, all with an unprecedented level of safety and dependability.

INHERENTLY SAFE

No risk of fire caused by thermal runaway4

WHY AVALON AND NOT OTHER FLOW CHEMISTRIES?

EXPERIENCE WITH COMMERCIAL INSTALLATIONS AND OPERATIONS

Vanadium flow batteries have a proven track record of deployments at scale; non-vanadium flow generally at earlier stage

RELIABLE AND SIMPLE CHEMISTRY

Vanadium/Vanadium battery invented to avoid shorter lifeand higher maintenance of non-Vanadium flow batteries; e.g. no stripping cycles, electrolyte “polishing” or continual pH adjustments needed to maintain performance

WHY AVALON AND NOT OTHER VANADIUM FLOW?

PROVEN, STABLE PRODUCT

Avalon’s customer testing and independent assessments have verified stable performance with near-zero maintenance and high availability3

RELIABLE AND SIMPLE CHEMISTRY

Fully assembled turn-key product, quality controlled at the factory, delivered complete to the customer, for fast, low cost installation

AVALON’S BATTERY IS EXTREMELY SAFE

In particular with respect to flammability, toxicity and reactivity
