Ammonia: The missing link in the hydrogen story ?

- Hydrogen has become a central element of EU plans to reach net-zero emission by mid-century. The hydrogen strategy relies partly on imports of hydrogen produced from places like North Africa, the Arabic Peninsula and Ukraine. How will this work in practice?
Globally, 50% of all hydrogen is today produced by the fertiliser industry who uses it to produce ammonia, the main building block for all other nitrogen fertilisers.
Storing and transporting hydrogen is a challenge as it is the smallest and lightest molecule in nature and it liquefies only at the extremely low temperature of -253 degrees Celsius. Ammonia, though a different molecule, has 50 % more hydrogen than hydrogen itself. It also liquifies at -33 degrees and can be handled easily, similarly to liquified natural gas.
To deliver on the net-zero objective, Europe needs decarbonised fuels in sectors where electrification is not an option - like heavy industry, some areas of transport or heating. Ammonia is today used as a base material for several industrial products, most notably nitrogen fertilisers, but it could also be used directly as fuel for shipping and other industrial applications.
It seems like ammonia is viable as a fuel for freight transport in areas like the USA where railroads are not electrified. As indicated, we already have viable, proven means of transporting ammonia by rail. It seems feasible to adapt diesel electric locomotives from hydrocarbon fuels to ammonia. The financing of this is easier due to the inherently modular nature of locomotives, compared to the risk associated with converting a massive container ship from bunker fuel to ammonia, which might not be viable for existing ships, but only possible for newly constructed ones.
I saw a ship engine builder say the other day that 50% of new orders are for 'flex fuel' systems. It seems like it is possible to make ship engines that can run on ammonia when it is available and other fuel when it is not. That makes a lot of sense from a buyer's perspective, it 'future proofs' the ship.
@@Greenammonianews I don't think that would work, given that ammonia needs to be stored in a pressure vessel at about 100 psi. You wouldn't provide that storage unless you are going to use it. Flex fuel would open up the ship to running off of synthetically produced methanol.
Nice to hear you Mr Herrero ...Always oriented on innovation ready for revolution.
Perhaps political incentives a too produce green hydrogen and ammonia and for farmers to convert from ammonia based fertilizer to the use of cover crop cultivation utilising plants that produce root nitrate nodules with no-till would reduce the reliance on petrochemicals ?
Yeah, I think Sri Lanka tried it last year.
Metal hydrides seem like a promising new discovery in the storage of hyrogen. As well as other hydrides.
To consider NH3 as an alternate to fossil fuel, there are two elementary Qs that need to be addressed: 1. What is the raw material required in NH3 production? 2. What is the carbon footprint in NH3 production? None of the speakers addressed this vital points.
A company in Canada making ammonia from Green Energy the company name is fuel positive . They can make ammonia on site. Look up fuel positive is a company on the Canadian stock exchange. You can buy shares in the company and promote them at what they do. and look up some of there videos ..my name is Patrick O'Brien I am 95% green and I live in Ireland I am off the grid 20 years. I produce all my power from solar power I am hoping that I can put ammonia in my car.
Fuel Positive is in the process of installing the Field Test NH3 Production Unit on a Farm in Canada that will produce 500 L /day ammonia. Operation should start end summer. The farm will produce its fertilizer on site, NH3 will be stored in a tank and from there they will use it as fuel to power the machinery.
The NH3 Production Test Unit produces NH3 from Air, Water and green electricity.
In collaboration with Dr. Dincer they work on a Fuel Cell running on Ammonia.
The future is decentralized production of NH3, Farmers will produce the fertilizer on site. Transport companies will be able to produce their NH3 fuel on site and the private sector will install NH3 Production Units at home to power an electricity generator, power the heating system, produce NH3 fuel for the car.
The cost of NH3 is very economical according to the calculation of Fuel Positive.
Mr David? Please give me some information about fertilizer Plant which use Green Hydrogen to mix NG to synthesis ammonia?thanks
During the Covid pandemic Oxygen was in short supply in many hospitals world wide. I Hydrogen is produced using electrolysis the Oxygen can also be sold,
Use nuclear energy for electricity production as well as High Temperature Steam Electrolysis for hydrogen production
Is Nuclear a renewable resource ?
@@duckface81 clean if you ignore the waste spent fuel ... Plus it's not practical for global adoption because of a number of reasons including safety and proliferation.
@@faceclutch5555 thorium, breeder reactors using depleted uranium can be used as a fuel source...they r safer, are not as radioactive, produce less waste....throw in some molton salt, got urself a pretty nice nuclear reactor
@@yoyoleafs2237 also the waste products have useful applications, i care about the environment as far as real pollutants but this corporate green crap is a scam for gov't funding.
~12:40 when i hear bs statements about something like ammonia or h2 being less energy dense i always need to ask at what pressure?
In terms of volumetric energy density, it´s true at any pressure. Ammonia can be liquified at room temperature at 300 bar and have about 4x energy density.
@@michalfaraday8135 and liquid h2?
@@jeebus6263 Ammonia is still about 30-ish percent better. But the main advantage is you don´t need very low temperature.
@@michalfaraday8135 I assume you meant PSI, not bar. 300 PSI is ~20 bar. Ammonia can be liquified at room temperature already at 7.5 bar, but 20 bar makes it possible to handle up to 50°C.
@@Dayanto You are right, PSI, my mistake.
@22:42 Why the lady said we do not consider Hydrogen as an alternative due to low energy density when in reality, the liquid hydrogen density is roughly 2 to 3x more than commercial fuels like Diesel (45 MJ/kg), etc.
She also mentioned, their company is looking at Ammonia as an alternative source due to good energy density, when, on the contrary, the energy density of Ammonia (22.5 MJ/kg) is about 50% less than Diesel (45 MJ/kg), making it roughly 5/6 times less than hydrogen's energy density. This is confusing.
Perhaps she is referring volume energy density?
It is very challenging to produce and transport hydrogen easily and safely
It is very challenging to watch this video easily and safely.
Ammonia is too toxic, and then you have hazardous nitrogen oxides too.. What about methanol?
Nuclear for shipping submarines use it
You know GM tried it 50 years ago and it didn't work
GM also tried EV in 1996 - 1999, called EV1, but they didn't try hard enough, it "failed" as well. Anybody who knows what is up with GM, please reply.
@@xponen no GM made their first EV in 1906 and again in the 50s then 60s 70s 80s and then the 90s
@@terenceiutzi4003 AND then Sony made some new batteries,......
And gm has made 10 new batteries since and it still doesn't work
You know that 2 years before Sony brought out their outdated lithium battery GM developed their CATLIN calcium battery and the produced four more generations before their 4 generations of sodium batteries before their new silicon battery and non of them has been a viable power source!
yikes. Rather than actually discussing ammonia tech they'd rather babble endlessly about their climate views.
