Invinity Energy Systems: Pioneering Safe and Scalable Energy Storage for a Net-Zero Future
As the global transition to renewable energy accelerates, the need for reliable, safe, and long-duration energy storage has never been more critical. Invinity Energy Systems has emerged as a frontrunner in this transformation, delivering cutting-edge vanadium flow battery solutions designed specifically to support high-utilisation energy applications.
In a world increasingly reliant on intermittent energy sources like solar and wind, Invinity’s innovative approach offers the stability and dependability necessary to unlock the full potential of renewables.
A Brief History: How Invinity Energy Systems Was Founded
The Birth of a Powerhouse
Invinity Energy Systems was officially founded in April 2020, born from the strategic merger of two industry pioneers—redT energy plc (UK) and Avalon Battery Corporation (USA). This union brought together decades of experience in energy storage innovation, resulting in one of the most capable and ambitious energy storage companies on the market.
This merger not only combined technical know-how but also extended the company’s reach across key markets in Europe, North America, Asia, and Oceania. Today, Invinity is listed on the London Stock Exchange under the ticker AIM:IES, signalling strong investor confidence in its vision and technology.
What Sets Invinity Energy Systems Apart?
Vanadium Flow Battery (VFB) Technology
At the heart of Invinity’s offering lies the vanadium flow battery (VFB)—a proven, water-based storage technology that is safer and more durable than traditional lithium-ion batteries.
How Does It Work?
Unlike lithium-based systems, VFBs store energy in a liquid vanadium electrolyte. These electrolytes are pumped through cells to charge or discharge energy. The result is a battery system that can operate continuously for over 25 years with zero degradation.
Key Benefits
-
Non-flammable and Safe: No risk of thermal runaway.
-
Long Life Cycle: Over 20,000 cycles without performance loss.
-
Sustainable: 99% recyclable components, including the electrolyte.
-
Scalable: Systems range from a few megawatt-hours (MWh) to hundreds, depending on demand.
Real-World Impact and Global Projects
Proven Deployments Across Continents
Invinity’s battery systems are already making a significant impact worldwide, with over 75 MWh of storage deployed across 82 sites in 15 countries.
Notable Projects Include:
-
Energy Superhub Oxford (UK): A 5 MWh installation that plays a vital role in balancing the UK grid while supporting zero-carbon transport and heating.
-
Chappice Lake Solar-Plus-Storage (Canada): An 8.4 MWh project, North America’s largest deployment of vanadium flow batteries.
-
Spencer Energy Project (Australia): A dispatchable solar plant with an 8 MWh flow battery system, providing clean power on demand.
These installations demonstrate the flexibility, reliability, and economic feasibility of Invinity’s technology in real-world, high-demand scenarios.
Why Vanadium Flow Batteries Matter Now More Than Ever
Supporting the Clean Energy Transition
Governments and industries are pushing aggressively towards net-zero emissions, but achieving that goal depends on overcoming the limitations of intermittent renewables. Invinity’s technology provides exactly what’s needed—dependable, long-duration energy storage that enables renewables to become true baseload energy sources.
Economic Viability
Although upfront costs may be higher than lithium-ion, Invinity’s batteries offer a much lower total cost of ownership. With no need for replacement and virtually no degradation, the return on investment is unmatched over time. This makes it a wise choice for utilities, grid operators, and commercial energy users.
