The ‘sell’ of 100k shares @ 8.38 at 14:54 is actually a buy. Not bragging, but you can’t rely on how the trades are being reported.

Thanks 13thmonkey for the ammonia information. I see that the energy density is 4.3kWh/l, but the efficiency of the fuel cell would need to be taken into account - typically 70% according to Google, giving 3 kWh electric energy per litre of ammonia. If you compare this with diesel (energy density 10.4 kWh/l, large engine efficiency of 43%) which would give 4.5 kWh electric energy per litre of diesel (not including alternator losses). So - not so much of a difference in required quantities really. If ammonia is transportable and storable with the same infrastructure as LPG (thanks Boffin) - or indeed as diesel - at similar volumes, then that's a big hurdle removed to using NH3 fuel cells as a replacement to diesel engines for off-road and standby powergen applications. What's not to like? The potential is massive.

I work in the offshore oil and gas business and I see fuel cells as a possible candidate for emergency power generation, which is typically served by diesel generators (on offshore platforms). In an emergency situation or whenever main power from gas turbines in unavailable, the reliability of an alternative power source is more important than any environmental concerns with burning diesel. Whilst diesel gen sets are the accepted technology, even if you are not mechanically minded, you would appreciate the mechanical complexity of large (V16/V20) diesel engines and their auxiliaries and the risk that they might fail in use or on demand. The pool of people to maintain these machines is not unlimited either. If the reliability of fuel cells can be demonstrated - or independently certified - then such emergency or standby power could be another application for AFC. Not only for offshore oil and gas, but for hospitals and other emergency/standby users.
The other consideration is how much fuel would need to be stored. Offshore, an 18 hour emergency fuel supply is typically required as a minimum. For the AFC 160kW fuel cells, does anyone know what quantity of ammonia or hydrogen is needed per kW of electrical energy produced? This is quoted as a specific fuel consumption for diesel engines or as a heat rate for gas turbines. I can't see any comparable technical information on the AFC website, and I'd like to do some sums.

Yeah, Googled IHO. I guess that you’re not referring to the International Hydrographic Organization. There is an International Health Organization, a Baltimore based charity with operations in India. Maybe you’re thinking of International Rescue? All I have to say too. F.A.B.

Felt it necessary to register so I could ask DW: who or what is IHO and how do you have access to behind closed doors discussions? Would have thought that with such insightful knowledge, you would know that it’s the WHO that is the main player.
