Research & development
Figures conflict within the source document. The Invinity wireframe's
body copy says "over 80 patents" and "dozens of grid-scale projects", while its
statistics strip says 81 patents, 96 projects and separately 90+ projects
across multiple countries. Both versions are rendered above as supplied. Please confirm
the correct figures — and note these are Invinity's numbers, so they should be verified against
Invinity's own published data and dated before launch.
Technology advantages
Benefits of Vanadium Flow Battery technology
These capabilities make them ideal for renewable integration, utilities, microgrids and industrial applications.
Superior safety
A non-flammable water-based electrolyte removes the thermal runaway risk associated with conventional chemistries.
Virtually unlimited cycles
Charge and discharge with minimal degradation over the life of the system.
30+ year lifespan
Operational lifespans exceeding 30 years, supported by a reusable electrolyte.
3 to 18 hour discharge
Flexible discharge durations matched to the application rather than fixed by the chemistry.
MWh to GWh scale
Scales from megawatt-hour installations to gigawatt-hour projects.
Independent scaling
Power and energy capacity scale independently — size each to the duty cycle.
Applications
Applications for long-duration energy storage
Vanadium Flow Battery systems support renewable energy integration, utilities, commercial and industrial facilities, microgrids, behind-the-meter installations and critical infrastructure requiring reliable, flexible and long-duration energy storage.
