A hello to all customers in Perth !
There are "fantastic news for the customers in Perth, as they can now benefit from a treatment service with a significantly lower carbon footprint, helping them with their ambition to become the most sustainable small city in Europe.”

I did't know that either, but perhaps this is a model for the 'slightly' larger city of Perth in Australia and helps VR8 to show the benefits of VRFB's in Australia:

"Scottish Water has completed work on its first large-scale battery storage project to accelerate its drive towards net zero emissions by 2040.
Four vanadium flow batteries, manufactured by Invinity Energy Systems, have recently been installed at the waste water treatment works that serve the city of Perth. The batteries are capable of storing up to 0.8 megawatt hours (MWh) of energy and will be used to store power generated from more than 2,520 solar panels, with a combined output of over 1 megawatt (MW).

By combining battery storage and solar power, the carbon footprint of the treatment works will be cut by around 160 tonnes of CO2 per annum – the equivalent of offsetting 580,000 miles from the average passenger car. The scheme will also help to power the utility’s first rapid electric vehicle charging points which have been installed at the site; and will reduce energy costs of the treatment works by approximately 40%."

So this is another hint for why vanadium is urgently needed, you know. Have a nice wekend.
