Completion of first commercial Australian VRB energy storage system for Hydro Tasmania
Completion of first commercial Australian VRB energy storage system for Hydro Tasmania
VRB Power Systems Inc.’s subsidiary Pinnacle VRB Ltd. reported that the commissioning of the King Island Vanadium Redox Battery Energy Storage System is now completed.
VANCOUVER, Nov. 21, 2003 — VRB Power Systems Inc. announces that its 66 percent owned subsidiary, Pinnacle VRB Ltd., has reported the following:
The commissioning of the King Island Vanadium Redox Battery Energy Storage System (VRB/ESS) is now completed. A Practical Completion Certificate was issued by Hydro Tasmania on Nov. 14, 2003.
King Island, a small remote location off the south coast of Australia supports and operates 5 wind turbines ranging from 250 – 850kW and Four Diesel generators at 1.5MW each that act as a remote grid to supply power to the local residents. Pinnacle’s 200 kW x 4-hour (800 kWh) VRB/ESS installation has been integrated with the wind turbines and diesel generators to form a 3-way hybrid system.
This new facility forms part of Hydro Tasmania’s King Island Renewable Energy Expansion Project and will improve power supply and quality to the community of King Island. The Australian Greenhouse office is also a stakeholder in the project.
Forming an integral part of the King Island’s power system, the VRB/ESS is used to smooth the short term output variations in the wind generators and the customer loads whilst providing frequency and voltage control and to implement a system of “load shifting”, ensuring optimum performance of the diesel and wind generation hybrid system.
The presence of the VRB/ESS has raised the level of deliverable power and has allowed for the ability to provide “firm capacity” from the existing wind generation. The newly integrated system reduces the required use of the diesel generators thereby reducing fuel costs and emissions of diesel exhaust into the environment.
The successful installation of Pinnacle’s VRB/ESS for Hydro Tasmania and the Australian Greenhouse Office is a key milestone in the development and commercialization of Pinnacle’s Vanadium Redox Battery Energy Storage technology. The demand for a reliable and versatile Energy Storage System is becoming increasingly evidenced worldwide and in a number of markets including the industrial and commercial sectors that are not adequately serviced by existing battery technologies.
Now its a world wide acceptance
I think VFB’s are reaching world wide acceptance alecfra … and especially China-wide acceptance*..
(…*Arvidson says China added more than 25GW hours per annum of vanadium flow battery (VFB) and vanadium electrolyte manufacturing capacity last year to support the rollout of VFB storage.
To put that into context, that equates to 207,690 tonnes of annual vanadium demand,” he says.
Australian Vanadium aims to produce 11,200t per annum, roughly 5% of the Chinese gigafactory demand added in 2023… [ref]
But the fact is that 2003 Tasmanian VFB failed after a short time and had to be replaced alecfra!
Why did you not include that information in your post?

[5] …, the system proved to be not robust enough and failed after a relatively short life. It has been replaced with a 1.6 MWh "advanced lead acid technology" battery.[6]
Apparently - according to a 2018 review - the ‘advanced lead battery’ can only store power for 45minutes!

Anyway I’m beginning to think it’s no wonder VFBs are being so slow to get ‘out there’ with the history of failed batteries, companies like the Australian one - Windimurra - south of ‘Nintha going toes up (see @Hawk70 commentary on that [here]), China ‘stealing’ the show and grabbing the patents when the US was getting interested but looked the other way… and putting the kibosh on vanadium prices … plus Elon stepping in with his massive funding and bright and shiny lithium grid batteries.
Are we (VFBs) actually going to make it into realistic commercial, profitable production this time round?
