Mrremmy - regardless of whether your or I would like to make mixed acids electrolyte ( that can pretty much only be supplied to UET ) the environmental reports illustrates that that is not on the cards. There is not a single mention of Hydrochloric acid.
Remember that Rongke Power, who are making the Dalian 800MWh, although they are very closely associated with UET, are unable, or chose not to, use the mixed acids electrolyte on that project. Remember also that the patent and licensing is controlled not by UET, who you might be able to cut a deal with, but PNNL, who themselves are run by a private company, Battele, on behalf of the US government, not a civil servant.
Thus it is not beyond the bounds of possibility that Battele come under political pressure from the current, or any future, idiot in the white house not to license patents for production of a very significant new energy storage component outside of the US, especially whilst US Vanadium mines are going to be making a fuss about getting up and running and wanting to put the boot into anyone already doing what they would like to, but outside of the US. We already have US academics running around saying that Vanadium is a 'scarce' and 'rare' element, when it is nothing of the sort. We don't need to put our heads on their block and then hope that we can ask the US government very nicely not to bring the axe down.
The beauty of the classic sulphuric acid electrolyte is that anyone can make it (if they have vanadium) and anyone can use it (our customers for example.) Thinking like normal technologists - that patent protection is a way to win market share doesn't work if you are trying to make a product that can be used by the widest possible group of VRFB manufacturers.
Remember it is not our goal to make UET the only VRFB company in the world it is to make the VRFB industry the largest possible grid scale energy storage industry that it can be.
