Knuttie, I've little knowledge as I stated in V markets and the drivers here. My interest is in "whats under the bonnet" of VRFBs. I don't wish to tell the BoD how to do their job, just curious to understand the strategic view of BoD and investor sentiment to pushing tech development. Frankly if you do believe me and think my interest as stated is genuine just filter me and I'll filter your nonsense.

James, probably a bit of both I'm afraid. I day job in life sciences R&D so have a natural inclination to technology and science. Hence the nature of the content I've been sharing, apologies to all BB members if this is the incorrect place to raise this. I confess to knowing little on short term cycles of V commodity pricing and the ups/downs of trolling/shorting, not that any of you would believe this anyway.

alfacomp sorry I didn't mean to cause offence, my search was a quick google search as I stated and on the first page of hits with "enerox" I found no patents assigned. It was cursory only, thanks for looking at EPO and finding some.

I guess my view of the tech development potential into VRFB research specifically that BMN could/should make (in my opinion) is 2 fold. Firstly it allows VRFB to more greatly displace Li-ion where existing end user deployment is marginal in decision making based on tech benchmarks (e.g. electric automotive transport). Secondly it gives greater market exclusivity (through patenting) of new VRFB devices.

A quick Google patent search not picking up any filed patent apps assigned to Enerox

Thanks Pdub, in a perfect world you'd hope Enerox establishes a intellectual property portfolio based on VRFB patent applications. I don't know if they have typically patented technological advances, but certainly getting marketing exclusivity of future VRFB device improvements should be considered as key to extracting maximum future value in the growth here.

Sorry for the flurry of messages but the VRFB has caught my interest. On the HCl option, one consideration is that water (high in HCl, low/absent in H2SO4) is an effective electrical insulator, so high water content is likely to reduce charge/discharge cycle efficiency relatively due to ohmic resistance losses. I don't suppose benchmark numbers are available to quantify this behaviour?

I'd be interested to hear views on whether investors consider allocating an increase portion of BMN resource into R&D activities for improvements in VRFB devices is worthwhile. I would consider this would be indicative of the transition from commodity supplier to technology/VRFB product supplier. This is where I'm hearing the BMN growth story will come from.

Certainly weight is one of the negatives against what is otherwise a large array of positive performance criteria vs rival battery tech. I'd like to see investment into VRFB addressing this weakness to increase breadth of applications for VRFBs. Choice of acid is a clear one to me, but perhaps there are other design criteria beside weight (e.g. viscosity of electrolyte such that high viscosity is less efficient due to pump having to work a bit harder)

No problem, but having the BB welcome new investors like this will if anything hinder the growth of BMN so is counterproductive to many LTH hopes. On the acid question composition on electrolyte, I'd be interested to hear what degree of investments (i.e. %of profit) is being allocated into R&D of VRFBs. I would hope its relatively high to reflect the corporate ambition to grow the market through identifying new end user applications for VRFBs. I would assume this R&D being directed through one of BMNs recent VRFB subsidiary companies as BMN have other fish to fry in Vanchem development and V extraction/mining

and by extension if low pH acidity is the only requirement for VRFB then have other acids with superior weight/proton ratios be potential superior, e.g. phosphoric acid (trivalent) whereas sulfuric is divalent and hydrochloric monovalent?

that's is for HCl as carrier the weight/power deteriorates in VRFB due to the additional water required over sulfuric acid?

Hopefully this starts to dispel the naysayers on the BB who have told me to "Foxtrot Oscar" as I'm a Troll - LOL! Thanks AlfaComp for the referral to BMN corporate presentations, if anything it reaffirms that BMN are indeed at hot ticket worth backing. I had a question on the carrier acid in VFRB which in BMN info states it can be sulfuric or hydrochloric acid. I note that industrially sulfuric is typically prepared as 98 v/w% whereas HCl is 35-37% v/w% in water (as pure HCl is gaseous @RTP). Presumably from a technical perspective in VFRBs its the proton/H+ requirement (i.e. low pH) therefore is sulfuric acid preferred over HCl in VFRB since presumably in lowers the net weight kWh density potential of the given electrolyte?

Ophidian, I will and come back later next week if I have any questions I can't answer. Thank you all for your patience and signing off for today. Good weekend all

knuttie, I will reiterate judge my by my actions and not any preconceived perception. I really hope BMN flies upwards into 2020 and beyond

Average investor. My investment is driven by the compelling story of BMN with V. Nice earner in steel, but the boomage potential for growth is the renewable power storage. I admit I haven't depth of research as many on this BB, but I'm keen and wish to learn more. I really see climate change rising up the political agenda and VRFB being a piece (potentially big piece) of the future jigsaw require for decarbonisation of energy. Given all you longtime BB members are so well knowledge I'm just asking for where the best tech info on VRFB is, in particular how its competes vs rival options

I'm also working with public sector folk in my local area on future investments for renewable energy storage in chemicals manufacturing (I'm based in Scotland) and so far I've only heard mention of green H2 being mooted as the feedstock choice. I'm not even sure the team looking at the potential deployment options have considered VRFB.

I would ask you judge me by my actions and contribution to this BB over time not by other BB participants that may have trolled in the past. I work in the life science sector and so appreciate technical information on VRFB and how they measure up against alternatives for renewable power storage. Given my scientific background I work on evidence and data not hearsay/subjective opinion. I do think VRFB are the untold story for renewable power storage, but vs green hydrogen and other vectors the story is not so well known.

Paranoid Halespur…. I have a sizeable BMN holding in my ISA account and do wish the value rises with my long holding position I seek. I can see a lot of future growth for BMN and like all the RNSs over recent months to develop the battery applications. This hostile language for entrant investors into BMN is really unhelpful. I would like to thank Alfacomp for his objective answering and lets try and avoid hostile subjective responses which are incorrect.

Thanks Alfacomp for the concise answer, I guess its a matter of horses for course in terms of deployment of H2 vs VRFB. I guess though charging/discharging efficiency is a big driver with VRFB winning on this basis.
