" He thought ZnBr flow was and will always be too expensive in comparison to other technologies."

This seems to be at odds with the CEC and DOE aims, at least for the technologies and suppliers they choose to support after this initial phase.

Acciona Energia don't seem to be fazed by that either, they too could drive volume if they choose to do so. Queensland Energy could probably help out too depending on which direction they choose.

I'm intrigued by the X10 too, how that might lower the price point per installed MWh of installed storage, if it becomes a product.

Not to worry. I'd just let things play out. I'm quite confident the team at Redflow will continue to develop the product, style and capability and it sounds very much like they know many of the people who matter, the people who make the decisions, not just the ones who talk about them. There are times when you need to move through the latter to reach the former.
