Default Scaleable VRB Mass Storage installed in 70 sites

Imergy's inherently scalable technology is the foundation of a strong product portfolio that addresses multiple applications with the need for fast response and long duration output, from kilowatt to megawatt scale and from off-grid to grid-connected, while providing the lowest (levelized cost of energy) total cost of ownership among battery technologies. With more than 200 cumulative years of demonstrated results, the Imergy ESP's proven technology has been installed in more than 70 sites and some of the world's harshest environmental conditions. Imergy's application focus falls into fImergy's segments: renewables integration, peak shaving, micro grids & telecom installations, and grid power reliability.

Imergy's ESP system stores energy in nonflammable aqueous-based liquid electrolyte using a simple exchange of electrons among different ions of the common metal vanadium. A small volume of liquid electrolyte is continuously pumped through a stack of cells, where it is either charged or discharged, by adding or removing electrons and then stored in tanks. By eliminating the phase state reactions which limit the lifetime of conventional batteries, Imergy's flow batteries provide an unlimited number of charge/discharge cycles over the full capacity range with 10+ years of consistent performance.

Over the -5 to 50C operating range, no power is consumed to either provide active cooling, as needed for most other batteries, or heating of the chemistry, as needed in molten metal batteries. The significant volume of liquid in the electrolyte tanks provides thermal inertia to naturally moderate the battery temperature. Unlike all other batteries there is no charge nor discharge derating as temperature increases above 40C.

The power and energy (output duration) of Imergy's battery systems are independent. Output power is determined by the size and number of cell stacks, while energy is determined by the volume of liquid. This enables the increase in output duration by many hours - from 2 to 10 hours - just by adding more liquid electrolyte, which is about 1/3 of the system cost. The electrolyte is never consumed nor used up and can be totally reused. This flexibility enables power providers to scale energy storage systems as their sites grow, at a fraction of the cost of conventional batteries. Conversely, power and energy are packaged together in conventional batteries, requiring a doubling of battery cost for every doubling of output power or duration.

Ed. Note: Hard to not get excited about this!

Australia is very well placed re Vanadium resources with likely a third of the world's recoverable resources.... Australia the lucky energy country.
