Does anyone have a link to uses for Acid remediation?
There seems to be a link with contaminated land but I don’t think that’s the use here.
What a lovely dilemma, IMHO we are invested in a company who after years of research have successfully brought a range of products to commercialization stage, not just any old products but products that are desperately needed it may -will take a while to get traction as it involves big sometimes complex decisions before sale is made.......etc etc....but does it sound daft to be thinking of some sort of link up with ITM?
Chipyjo,
Google acid mine drainage and scroll down to the ion exchange section in Wickipedia possibly.
Historically the UK has been very good at inventing/creating new technology but very poor at marketing/selling it
Or try this:
"MEMBRANE SEPARATIONS | Diffusion Dialysis
T.A. Davis, in Encyclopedia of Separation Science, 2000
Introduction
Diffusion dialysis is a separation process in which an ion exchange membrane separates a source solution and a receiving solution, usually water. Anion exchange membranes are notoriously permeable to acids, and diffusion dialysis exploits this property to separate acids from salts. A common application of diffusion dialysis is recovery of acids from waste metal pickling solutions, the strong acid solutions that are used to remove oxide coatings from metal parts before they are painted, galvanized or electroplated. Cation exchange membranes are permeable to bases, and this is utilized to recover NaOH from aluminium etching solutions.
Diffusion dialysis of acids through anion exchange membranes was reported as early as 1964, and was installed on an industrial scale by 1980. There have been many laboratory studies on membrane properties and transport of acid through such membranes. Therefore, the discussions that follow concerning the theory and practice of diffusion dialysis will focus primarily on acid transport through anion exchange membranes. Base dialysis is relatively new, and there is not a large body of knowledge about the mechanism of transport, design criteria and performance of that process. Until such information becomes available, it is reasonable to assume that the theory and practice of base dialysis parallels that of acid dialysis.
Since ion exchange membranes have an ionically charged polymeric structure, their discrimination between solutes is based on ionic charge. Anion exchange membranes are easily permeated by anions, but cations are rejected, because the positive ionic change of the membrane matrix repels the cations. Unlike other cations, hydrogen ions are an integral part of the water that pervades the membrane, and hydrogen ions seem to permeate by a different mechanism that avoids the rejection of the charged polymer structure. Anion exchange membranes transport acids while rejecting salts.
Figure 1 illustrates diffusion dialysis for recovery of HNO3 from a solution also containing Fe(NO3)2. The anion exchange membrane is quite permeable to the NO3- ions, but an equivalent amount of cations must also pass through the membrane to maintain electroneutrality. Because of their double positive charge, the Fe2+ ions are strongly rejected by the membrane, but the protons are transported rather easily. Thus, a useful separation of acid and salt is achieved."

Well there is the delayed sell that brought the price down - 200K.
Thoughts NI??? RSP??
Timber!!!
This is falling fast! All that bs about rsp is exactly that...trying to prop up the sp as they exit
Loads of £10k sells appearing suddenly....why???
Lots of new posters on this share since the rise. All have their own reason for posting. This isn't necessarily for the benefit of the long term holders, but we are still in a much better place than 8 weeks ago!
Also long term holders weren't selling with the rise and with the small amount of shares that are liquid causes problems for the MMs as they like a large churn so did they aid this volatility?
Thanks Bumble.
So if the exchange membrane is acid tolerant then it could be used in PEMs. As vehicle fuel cells aren't AFC target market they could licence the membrane for that use surely?
I suspect it is not that simple Chippyjo. A PEM fuel cell has the membrane, but this has a catalyst mixture and electrodes in contact with it, and I do not know if the chemistry will work if there is a simple switch in one component, the electrolyte membrane.
However the company have told us they will not licence the membrane for use in other fuel cells, so it seems it will not happen. Why help your competitors when you have a product, the hi power cell, that does the same thing?
Bb i was thinking purely for licence agreement in non market activities. Bond said no cars so why no licence for car fuel cells if the membrane works. Car market will be huge.
Presumably because a PEM fuel cell might still be better in a car.. It was pretty specific about the uses wasn't he, possibly trains and boats. I don't know why.
It's an Alkaline membrane, so my take on it is that PEM manufacturers would licence it and instead of making acidic PEM cells, they would make alkaline AAEMFC fuel cells.
The benefit would be that they can lower TCO by using lower grade Hydrogen or by using Ammonia, and use lower pressure, meaning cheaper component cost and simpler manufacturing. There are many savings to be had here.
This then makes fuel cells far more attractive to the World, and would give a huge boost to the transition to a Hydrogen economy.
AFC cannot take on the World, either they license out the membrane or they'll get bought out by a huge Company that will, before they've had a chance to really capitalise on the potential of the membrane.
Its encouraging that we are looking for more staff, especially the research scientist position. Its clear AFC are intending to actively develop the new products in house, and guessing in conjunction with De Nora. exciting times.
I think for the time being cars are out for the membrane fuel cell because the power density requirement is much higher for fuel cell cars, due to the restricted space to fit it in.
The Toyota Mirai fuel cell (FCA110) has an output of 114kW and has 370 cells. Compare that to the picture of the AFC membrane fuel cell and you can see that to get 114kW it would be way too big.
But, that's not the end of the story, as AFC and De Nora will no doubt be working on improving the power density to the point where it can fit in cars.
The fact remains haggis, AFC have said they are not producing fuel cells for cars or licensing out membranes for other fuel cells so it is an academic debate.
BumbleB,
It's only a fact as far as that's what they are saying right now. They've told us LOADS if things over the past 11 years I've been a shareholder and they've done very few of them, so equally it must work the same in the opposite direction, and things they say they aren't doing (now) they may well do in the future.
..... Especially if the price is right!
And the cell is up to the job, which it is not at the moment. I agree they might make breakthroughs in that direction, but until they do I won’t be speculating they will.
Number one priority is going to be making the cell durable with the existing power density, I would have thought.
Not making it durable, proving it is already durable by showing its longevity chart and its ability to work with low grade Hydrogen or Ammonia.
"A key number of success criteria were identified for AlkaMemTM in advance of commercial sales with several of these already having been demonstrated, including conductivity, ion selectivity and operating temperatures. Focus in 2020 now resides in demonstrating the longer-term stability of the membrane across key market-based applications."
Demonstrating being the operative word.
I am not sure I understand the point you are making there.
