Vanadium Redox Flow Batteries

The Vanadium Advantage

There is an increasing demand for long lasting, reliable, fireproof and safe electricity storage in Africa, and a global move towards renewable energy resources. Due to the intermittent nature of renewable energy (eg. only produced when the sun shines or the wind blows) there is a need for Battery Energy Storage Systems (BESS) which can store excess power generated from renewable resources until needed, providing constant, reliable, round-the-clock electricity.

The Vanadium Advantage

Vanadium Redox Flow Batteries offer a superior, reliable, safe and sustainable energy storage solution with clear advantages over other batteries for grid and large scale energy storage.
Redox Flow Batteries (RFBs) differ from other types of batteries, where chemical reactions occur within a single container. RFBs store energy in liquid solutions stored in separate tanks. These are then pumped into cells where the chemical reactions takes place. This means that energy capacity and power capacity can be easily and separately scaled. The electrolyte solutions used in Vanadium Redox Flow batteries are non-flammable and reusable. Vanadium Redox Flow Batteries offer an extended lifespan of at least 20 years at 100% charge capacity with little maintenance required.

The issue with other batteries

For grid and large scale energy storage, the market is faced with low cost solutions that:

Degrade quickly with repeated cycling, losing capacity the more they are used.
Advertise a 10 year lifespan, but often only last 3 or 4 years
Are costly to own and maintain
Pose safety hazards as they can easily ignite and cause fires
Use toxic materials and cannot be recycled
Are not well-suited to desert conditions.

Why choose VRFBs?

Vanadium Redox Flow Batteries are well-suited to mid, large and grid-scale energy storage.

ADVANTAGES

Guaranteed 20+ year lifespan.
Can be charged and discharged thousands of times without losing much capacity.
Require minimal maintenance
Aggressive charge and discharge tolerant, and can remain discharged indefinitely without damage
Lowest total cost of ownership over the lifetime of the product.
RFBs are easily scaled. Energy capacity can be adjusted by increasing/decreasing the electrolyte. Power capacity can be increased by adding more cells.
The electrolyte solution can be recovered and reused
Safe and non-flammable. Uses non-flammable aqueous electrolyte and other materials.
Wide operating temperature range
No noise or emissions, 99% recyclable and significantly lower environmental impact.
Flexible in terms of installation and location. VRFBs can be installed in remote areas, urban settings or even on ships, and are easily integrated with renewable energy sources.
Intelligent monitoring and control
Perfectly suited for Namibian desert conditions, rain or shine

Proven technology partner from Europe.
All components are sourced from world's best from industry leading companies, verified to last longer than 20+ years the battery is guaranteed for.

Reliable 20+ Year Performance.

No Babysitting Required

E2S System's Vanadium BESS offer lowest TCO at 100% charge capacity when compared to Lithium-ion. Use your battery as much as you want to, whatever its state of charge. With no warranty limits on battery cycling, E2S System's batteries deliver stacked revenues and future-proofs your investment. Over 25 years, its enormous throughput advantage results in the lowest price per MWh stored or discharged (LCOS) of any storage technology. In fact, a single VFRB will deliver 3x the lifetime throughput of a comparably-sized lithium battery.
