Could it be that AFC are holding back on announcing completion of the assembly system at Harrier Hangar in the hope that they can combine this with an order. This would go down much better than confirming that HH is up and running with the employees assigned to it.
AB told S&P Global Platts on today "Alkaline chemistry differs from PEM in that it can accept low-grade hydrogen. By low-grade I mean down to sub-90% purity versus the 99.9%- plus PEM needs," The Fraunhofer membrane can separate hydrogen from methane with a purity in excess of 90% so we have the possibility of an AFC fuel cell connected to a mixed gas supply in a gas network . Just another possibility for AFC.

If I have got this wrong, I apologise, but I seem to remenber that they did tests down to 75% purity with success. Members with better memories might be able to give chapter and verse. In addition the purity produced by the fraunhofer membrane is meant to be in excess of 90%
This follows on from my comments re the Fraunhofer Membrane. The membrane technology makes it possible for hydrogen and methane to be routed through the national natural gas grid together and then isolated from
one another at their final destination. A major step forward in the transportation and distribution of hydrogen as an energy source. The HYPOS project is to network power and gas grids, storage stations and hydrogen pipelines in an intelligent infrastructure in East Germany. This will create an energy network that can serve as the basis of an extensive and cost-efficient hydrogen economy.
What will this mean for AFC? If it works, and there is no reason to suppose it will not, then the technology will almost certainly be rolled out in countries with established gas supply pipelines. That then means hydrogen of 90% purity will be available at the end of a gas pipe.
Cost are always important and in this case an AFC fuel cell would not need the addition of storage for hydrogen or no cracker for ammonia thus CAPEX is reduced and there would be no need for the scheduling of and cost of deliveries of fuel thus OPEX is reduced.
This is particularly beneficial to AFC as the purity of the hydrogen is not 100% and thus could not be used by PEM cells. I believe GENCELL have a fuel cell which can work with reduced purity but there is a question whether this can operate continuously like the AFC cell.
The future's bright - the future is AFC!
Further to this topic and in answer to Bumble the following paper (2nd page) indicates that the hydrogen separated in this way can be used for emission free power so it implies AFC could use hydrogen which has been separated by the Frauhofer filter from the methane in domestic gas supply pipes . If it is emission free as stated it will not contain methane. If the infrastructure of gas supply pipes can be used to transport methane and hydrogen and hydrogen can be separated out at will this opens up further the potential for the use of AFCs fuel cells. The putity of Hydrogen produced this way has been quoted as 90% which AFCs cells can cope with. The technology to support hydrogen is marching on at pace.

Yes the methane would obvoiusly be a problem but the link given by Itsallbull does not indicate what the contaminant would be but the filter will not let the larger methane molecules through apparently. So maybe there would be other contaninants of small size in the gas supply which get through. Anyway an interesting approach to separating components of a gas which may be of use to AFC in the future. I have attached Itsallbulls link below.

So in theory anywhere you can supply gas in pipes you can use this membrane to separate out to get 90% pure hydrogen thus our fuel cells can be anywhere on the end of a gas pipe. Logistics for hydrogen or ammonis not needed. Another interesting possibility. I think it is all stacking up in AFCs favour.
There a re various ways of making it exciting and virtually eliminating the dust problem. One suggestion that has already been made is that you run each car separately against the clock, a bit like show jumping. Another alternative would be to have alternative track sections of equal length as part of the total track which could enable a trailing car to do a fast section without dust and take the lead. This would make the race very exciting. Just a thought to overcome the dust problem. I am sure there could be other possibilities.
Hi Beach I think I have read that the S version uses 3 9s H2 and that would be a priority if they are to be used in transportation so that the feed can be ammonia. You make me wonder if potential customers might be thinking the same re obsolecense of the L version and therefore waiting for the S version especially if it is a cheaper alternative.
Regarding the use of the S fuel cells I thought that these would occupy less space because of their power density and there would be less ancillary equipement ( no fluid electrolyte with all its requirements ). The fact that a major market for these would be in transportation does not preclude their use in non transportation and if the economics make sense why not. So if they are cheaper and more versatile would they not make the L fuel cells eventually obsolete? Any thoughts?
Only the sales in a specific financial year are relevant to CGT. For each sale the gain or loss will be the sale proceeds - the purchase costs and the sum total of all sales will give you your liability to CGT if you pass the threshold. The purchases in any given year will only become relevant when those assets are sold. You might have the possibilty of offsetting losses from previous years and in some juridictions there is a reduction for years of ownership but I am not familiar with these as I no longer live in the UK. I guess your accountant wants to record the sales so he can use the information in subsequent years. Regarding a spreadsheet Risky it would not be that difficult to make one and I expect there are some out there on the internet you could use specifically for CGT.
I think this is incorrect because CGT is a tax on the gain therefore you need to subtract the cost of acquiring the shares in the first place. If they were all bought at the same price, the number pf shares to sell would be 12300 divided by ( sale price - cost price) . You can also deduct buying cost and selling costs as well if you want. If your sale price were £0. 49 and you paid say £0.30 for them then the result is 12300/0.19 = 64,736 shares. Hope that helps.
Interesting - The British Motor show website says that in The Technology Hall
The Technology will showcase the latest tech & answer all your questions, featuring the latest Electric Vehicles, The Technology theatre, Automotive infrastructure and tech suppliers and the AFC Energy Alternative Drive expErience.
Anybody know or guess what is the AFC Energy Alternative Drive expErience It doesn't sound like a charger?
Thanks to Haggis and Bumble for comments re the GenCell but clearly they have a very restricted capability compared to AFC fuel cells. If you think the ability to use reduced purity hydrogen is important it could have been mentioned along the lines - The AFC fuel cell is capable of using lower purity hydrogen from ammonia which is liquid at normal temperature and easily transported unlike pure hydrogen which needs to be compressed and has safety issues regarding transport. Not too technical i think. If Zeus did not take note of this their valuation would probably have been higher!!
