Hi 'acorn' I hope 'dyeman' won't mind if I step in here and answer your questions.
Q. "Now that it's pretty clear that power sharing is going to be the go I would imagine ( and hope ) that Redflow is already across this idea."
Ans: You can be -absolutely-positively-100%-certain- that they are indeed, 'right across this idea'.
Q. "The question might be how suitable is it to other systems i.e. the national grid ?"
Ans: That's where RedFlow's Executive Chairman Simon Hackett's considerable professional IT expertise comes into the picture right now, ie, he is using the expertise resident in his own IT company's expert group to develop the 'smartware' for the ZBM's 'BMS' and for it's ongoing inter-operability with the new generation of smart-grids.
Q. "Will the ZBM tech be as good ( reliable ) as it is being promoted ?"
Ans: RedFlow is -definitely-not- some shonky back shed fly-by-night bunch of fools. They started with their ZnBr Flow Battery research at the University of Queensland around 10 years back now and they have steadily implemented that initial scientific research into full scale product development with continuous testing and product improvement each and every year since. They have also worked in conjunction with Prof. Thomas Maschmeyer at Sydney Uni between 2012 and 2015 and incorporated the findings of his ZnBr team's scientific research into their ZBM's product development. They have already got working, commercial scale, ZBMs sold into multiple countries right across the globe and they are right now, offering a 10 year warranty on their ZBMs which means that they are already confident that their product's MTBF is already, greater than that.
Q. "Will RFX be able to manage the increased demand for their product in a short time ?"
Ans: That's exactly why, they made the very smart decision mid 2015 to outsource all stages of their ZBM's manufacturing process to FlexTronics in the US. FlexTronics is the second largest OEM electronics manufacturer in the world and can rapidly provide ramp-up of volumes, as increased demand warrants it.
Q. "Will they be able to reduce the cost with that increased uptake ?"
Ans: In conjunction with their global manufacturing partner FlexTronics, Redflow have already, achieved a 50% reduction in their manufacturing process costs during 2015 alone, and they are confidently predicting even further ongoing, year on year cost reductions similar to, if not better than, the price falls already seen right across the solar-PV manufacturing industry.
Q. "RFX has the opportunity to get in at the bottom of the demand curve . Once this demand ramps up and other large companies get involved , it might be harder to get a foot in so it's a bit of a once in a lifetime opportunity imo"
Ans: RedFlow are -already- in there, at the bottom of the demand 'S' curve and positioned right at it's upward inflection point, with their world patented ZnBr chemistry ZBMs which already are, the-most-energy-efficient-Flow-Batteries-on-the-planet. It's just the rest of the world that has yet, to wake up to those facts, and you are absolutely right, it is indeed, a once in a lifetime opportunity to get onboard such a 'disruptive-technology' stock before the rest of the world actually wakes up, which should start happening in the next couple of months, once RedFlow 'lets the Genie out of the bottle' and gets serious about globally advertising, their new home / residential targeted Plug&Play version of their ZBMs.
Forget about all of the insane volatility happening daily now on global share markets, that's just the result of the death-throes of the global Petro-Dollars fossil fuel industry that's being played out right now before our eyes.
Renewable energy is definitely the new bunch of smart-kids on the block, and RedFlow is one of the very smartest, amongst them.
