i've seen this in Spain years ago.
Paolo, did you read about Heliogen - someone posted a link last night. Launch announced 19th November - New technology harnessing concentrated solar power in the same way that you can get a magnifying glass to start a fire (albeit, obviously, a little more complex than that). They reckon they can achieve 1000c - enough to split water, amongst other things. If it works and is scalable - which they say it is - then there is your clean Hydrogen of the future - inputs; water and sunshine....
Sadly Private Co, Silicon Valley funding or I'd have that in my long term portfolio !!
Absolutely load balance by storage that can be moved around unlike giant batteries.
Yes, I drive past my local farm which has 26 turbines and inevitably some of them are not rotating to balance energy at times of over-generation. In such circumstances creating hydrogen seems eminently sensible.
Paolo, when wind turbines are faced out of the wind to match demand and supply, thats not efficient either. Rather use the free energy to convert to a renewable green energy media.
Also Alkamem could open up many waste streams which currently have cost implications to deal with anyway.
I didn't know diesel cars could take ad blue. I thought it was just for trucks.
I reckon on a 23p finish today. Maybe news tomorrow.
Dictate error, meant to write "...Fuel cell 80% efficient, so if the H2 is used in a car 60% of your wind or nuclear electricity is lost, it's appalling..."
Electrolysing hydrogen at ambient temperature is in reality 50% efficient. Fuel cell 80% efficient, so if the H2 is used in a car 40% of your wind or nuclear electricity is lost, it's appalling. The idea of a hydrogen economy is best kept in the dialogue of a 1970s Dr Who show (Terry nation used to add it into Tom Baker's dialogue every now and then). If you do it with high temperature heat from say a suitable nuclear reactor (which we don't have, though it is feasible) then 80%. Pop the leccy into an EV and you end up with 95% of the energy taken as charge, back at the wheel motors for real motive power. Now that's progress. The lib Dems and conservatives want every home to have an electric heat pump, so that for every 1 kWh of leccy taken from the network, you get 3 kWh of useful heat in the home. Pop the same 1 kWh into an electrolyser and you get 0.5kWh of hydrogen energy, pipe it perhaps admixed with methane (=hithane) to the home (cannot exceed 8% in the mix of H2, due to embrittlement of the inner surface of the metal gas pipes still used in most LDZ networks, plastic replacement program due to complete 2055)...and the 1 kWh of electricity that went to the electrolyser is now in a 90% efficient condensing boiler, giving you 0.45 kWh of heat in the home. Thinking only of the hydrogen, imagining a pure hydrogen boiler if you like - you lost 55% of the electricity's energy. But from a heat pump you'd get 3 kWh so you gained 200% on your starting 1 kWh of electricity. As the late Professor Sir David Mackay used to say, and does again in his final interview on you tube (Google David Mackay final interview), pay attention to the numbers !!!! The science matters. ITM Power also claims to make slightly more efficient electrolysers, its share price has been all over the place since 2008, I held some and some AFC. ITM power is down today along with AFC. The lib dems are backing a heat pump in every home, not the hydrogen scam. AFC and ITM are still OK to trade, lots of volatility thanks to being frothy and "fashionable" with a band of believers, but they are like other past-fashionable stocks like KOD, UKOG, BNN and Lionsgold, not stock to hold long term because long term their prospects evidently aren't good. My long term safe-ish holds right now are eden, nano, and jog.
Yea urine contains a low proportion of ammonia, along with many other salts etc ...next time your new diesel car asks for some ad blu (concentrated ammonia) try piddling in the tank and see how far you get.
I'm surprised Nickel hasn't been back to tell us he shorted again at 28 this morning. Hindsight trader for sure. If he managed to short yesterday at just below 25 (right at the top) but cover at 24 as it gapped back up then he's surely as gifted as he tells us he is.
As for Bmac - we all know the stuff about future cash calls, the pending guarantee, no sales or revenue yet etc etc. It's always the same when a share rises dramatically for a few days - these guys turn up with the counter argument - often working in teams. So when they start agreeing with each other and thanking each other for their insights you can usually spot them.
A counter argument is always healthy though - and if we are not savvy enough to weigh the pros and cons for ourselves then its best to steer clear of the BBs.
Nikel hasn't got a clue, one minute he's long the next he is short, they soon got wise to him on the Serica Energy board.
I've been wondering how to get into renewable energy. I have made a small investment in VRFB batteries and vanadium based storage, and mining, but wanted something to do with energy production. Seemed to me that the transport side was vital, since there are many places where green energy is there for the taking but how do you get it from the middle of the ocean/desert to city centre London? Hydrogen of course is a nightmare, transporting it at near absolute zero temperatures. That led to googling energy density of fuels, which took me to ammonia. A lot on Australian websites. They have an abundance of potential green energy, and are looking to how to export it. AMMONIA seemed to be what they were lighting on. Huge strides being made in the production, with green energy and not by the awful Haber Bosch process. https://www.sciencemag.org/news/2018/07/ammonia-renewable-fuel-made-sun-air-and-water-could-power-globe-without-carbon
It is fairly energy dense, more than liquid hydrogen, about 1/3 that of jet fuel. https://en.wikipedia.org/wiki/Energy_density
And the infrastructure for such transport is already there.
I like this in the wikipedia article on Grid Energy Storage: "A standard 60,000 m³ tank of liquid ammonia contains about 211 GWh of energy, equivalent to the annual production of roughly 30 wind turbines." https://en.wikipedia.org/wiki/Grid_energy_storage
The other day nickel_investor made a very good call on another website (as he did yesterday here, expecting a fall from 25). I checked him out and saw what else he was following. Ammonia stood out in AFC and I was lucky enough to get in at about 15.5. Small start.... Thinking of topping up.... Nickel?! :)
Genuine question - I would if ammonia is / could be extracted from sewerage farms as a commodity ?
Just double checked that urine contains ammonia and I was correct. Cheers.
I've been missing a trick Bumble...
The dark arts of the compost heap
Bob Flowerdew is you man.... Its a very good activator for compost.. I've used it before.
Never heard of activating compost Chippyjo?
Funny I don't recall Percy Thrower or Alan Titmarsh giving us this info....
So whats the close price?
Urine is high in nitrogen hence why its good for plants, but can burn plants if its neat due to its strength.
Maybe the local pubs could have a new income stream. Literally a stream )
Actually, urine (diluted) makes a good fertilizer
Fairview: if you don't believe in the potential of the 'Hydrogen Economy' then this probably isn't the investment for you!
Are you taking the what not Yatchmaster?
This article talks about using alkaline exchange membranes to synthesize Ammonia without excessive heat and pressures, so potentially greener than using the Haber-Bosch process. Maybe AlkaMem can play a part in that ?
