CaSO4 is a new thing I think - an additional TiVAN byproduct from Speewah ore specifically?? Commercial value of this? Though it is in a different colour, whatever that signifies.

Circularity in terms of decarbonisation typically considers full lifecycle of material including recycling/end of life handling so as to reduce waste/calculate full lifecycle costs and carbon emissions related to that. This schematic could also be suggesting that TVN may also lease out/recycle/refine the vanadium electrolyte. This has often been spoken of as a viable option in the industry over the years to make VRFBs more affordable in this early phase of commercialisation. And this affordable solution then provides the impetus to scale VRFBs as well, not to mention the lowest cost to extract vanadium in the first place. Climbing up the value chain and additional job creation if TVN is to play a bigger circulatory role beyond extraction and processing.

Or simply that TVN is using green energy from grid powered by VRFBs for both beneficiation as well as processing in Darwin!

All speculation and conjecture of course when one gets carried away in their imagination.

I am still curious how short term operational CR will be done, especially on current SP, let alone longer term funding.
