And FWIW an  update from Invinity the other day …
It includes mention of interest from Australian decision makers, notes  lots of interest in moving away from lithium based storage batteries but says  customers are dawdling a bit (maybe waiting on the new, better, cheaper Mistral?)
…And Mistral’s on track for commercial release by Christmas but they at Invinity are loathe to take off the wraps
just yet…

Here’s some excerpts:

Commercial Positioning
The market for Long Duration Energy Storage ("LDES") continues to develop favourably for the Company as alternative battery technologies and domestic supply chains become an increasing priority for decision makers in the UK, EU, North America and Australia.
As such, Invinity has noted a growing number of proposed projects which specifically exclude lithium-ion as the energy storage technology, a trend the Company views as positive in the context of future demand for its vanadium flow batteries….

On Mistral …
..Jonathan Marren, Chief Executive Officer at Invinity said:
"The development team, in collaboration with our joint development and commercialisation partner, have rightly focused on ensuring that Mistral is capable of delivering the performance characteristics being demanded by customers and the market; I am very pleased with the results to date. We aren't yet where we wanted to be on working through the identified initiatives aimed at reducing production costs to the level we believe we can attain but have confidence this can be achieved in 2025 ahead of material volumes at sustainable margins in 2026 and beyond…”
