Just how insane are these Co2 climate freaks? Burning ammonia gives you nitrogen oxide, toxic to just about everything. And THAT to do away with co2, an eco friendly essential gas? They call me a climate denier? Better than those f*cking climate fanatics desperate to destroy my and my fellow deniers' f*cking earth. Stop f*cking Breathing, and do us deniers and the planet a big favour.

Page 48 f. of this study gives a forecast on the potential costs for producing green ammonia. At present it's not economically viable. If you burn it, you get ~6 kWh/kg. That's more than 10 ct/kWh.

My new engine can allow NH3 100% to be burned at high RPM. Make fuel at home from solar thermal to engine that turns generator which in turns makes NH3 with NH3 fuel maker. Store in propane tank at 1/2500th the cost of Li-ion. One year of fuel possible... Run car, truck, airplane... New engine is key. On twttter...

The most useless video...lots of researchers not doing anything to be finished completely.
But really, this is the only one video made without knowledge by someone who thinks he knows.
Very crappy video. Talking rubish about ammonia. This is a killer....can evaporate in the air and kill millions of people by accident.
Think before you talk rubish.
Think about the cost of these plans...to make it safety. Think....brainless man.

Ammonia: NH3
https://en.wikipedia.org/wiki/Ammonia

Ammonium: NH4+
https://en.wikipedia.org/wiki/Ammonium

As you can see, the interesting bit is the ion, the one with the + charge. It has an extra H, but it lacks the electron to maintain it. Usually, it finds a negative chloride ion to compensate, together they form the wonderful ammoniumchloride that Dutch people know as Salmiak.
https://en.wikipedia.org/wiki/Ammonium_chloride

Concern about how toxic this stuff would be are real as for any chemical process involving large energy transfer needed to propel a car. But let's also observe that Dutch people eat massive amounts of this Ammonium-Chloride for fun. If they invent an engine that benefits from these reactions, perhaps they should call it a dropmotor or a salmiak engine.

A lot of people don't seem to understand why this would be useful. Plain hydrogen has horrible energy density and the pressure you have to store it under to make it even reasonable to use as fuel is dangerous, and as people have pointed out, it leaks out of any container you try to store it in. Current batteries are pretty shitty for storing and transporting energy, they are expensive, and they only last a few years before they have to be replaced. One reasonable criticism people are bringing up is the toxicity of ammonia, which I agree is a huge problem, but batteries also contain toxic material so both forms of energy storage are flawed in this way. Don't get me wrong, there are plenty of issues with using ammonia as fuel, but all of the people saying to "just use hydrogen" or "just charge a battery" don't seem to see the major flaws with both of these. Also an alarming number of people are also saying this is stupid because it requires energy to make the ammonia... Duh, that's why it's called "energy storage". You use extra solar power to make fuel and store energy for when the sun isn't shining, and to power cars without requiring a long recharge time and a battery replacement every 5-7 years.

The efficiency of Hydrogen maybe lower than battery technology but the advantages is you don't need to disturb the planet by gathering different chemicals, no mining required, the only issue that needs to be sorted is storage, it will require a lot of investment but once the infrastructure is in place its there to stay as in existing infrastructure which could possible be utilized, I think at the moment work is being carried out on converting hydrogen to hydro carbons by combining hydrogen and carbon from the environment to create clean and efficient hydrocarbons with low carbon emissions for IC engines. ideal for an alternative for people that like IC engines and don't want to change to anything that doesn't make a lot of noise. I see a lot of negative comments about ammonia gas as a fuel, I think these technologies need to be tried in a control environment and then compared
then decisions can be made in regard to its safety, we should not jump to conclusions and create hysteria based on poorly advised information. a lot of cronies out there are against change because it may interfere with their sense of security but sometime we can be living with a completely false sense of security. change is inevitable, with every second that goes by things change, evolution is taking place, technology is no different.

If you burn it under ideal conditions, you get only nitrogen and water and no formed nitrogen oxides but I fear for the word"ideal". I wonder about the exhaust of those Belgian buses that ran on ammonia in 1943 because of diesel shortages.

I am not sure why people are over-reacting to ammonia. It is time to educate people about "facts". Ammonia was a nightmare for farmers in 1950s or 1960s. How do you face ethanol and methanol in your everyday life, without even noticing them? How do you drive a car with 18 gallons of highly flammable/toxic gasoline @ 70 MPH? How do you let your teenage girl buy Acetone to remove the nail polish? These are all double-standards. Something that makes ammonia unique is the possibility of creating ammonia in small scale? If the producing unit goes wrong, then the worst would be to evacuate the house or surrounding (withing 10 meters).

As someone from a country highly reliant on oil and seasonal rains for electricity, I'd welcome any method to store energy for our hot summers. Like, maybe ramp up production of these when we have abundant water.

Make ammonia. Only we don't really know how to extract energy out of it once we have it (please don't ask a terrorist). Well that makes petfect sense. And let's ignore hidrogen and oxigen that are produced in the first step.

one of the most efficient fuel cells are hydrogen-oxygen, (the highest possible energy storage) unlike batteries only hydrogen must be carried, oxygen is everywhere (same as hydrocarbon fuels), the problem is the extreme pressure needed, maybe a ammonia-oxygen fuel cell could be a solution to this, unlike water ammonia has a lot of energy (water can't be used as a fuel), the problem is the triple bond in nitrogen

Urine can make ammonia much easier, but the best way to store energy is h2o2 and/or solar electrolysis of h2o.

Please get the most basic principle of all right!

IT MAKES NO DIFFERENCE WHATSOEVER WHETHER AN ENERGY TECHNOLOGY USES CARBON OR NOT!

WHAT IS CRITICALLY IMPORTANT IS WHETHER IT IS >>RENEWABLE<< OR NOT.

The problem with fossil fuels is not that they contain carbon. The problem is that they are used in a NONRENEWABLE manner: Instead of the carbon in the spent fuel being used to create more fuel, it is just dumped into the environment and ACCUMULATES. It it was reused it would not accumulate.

Just what part of "RENEWABLE" is it that our society is so remarkably incapable of grasping?

If any fuel (including ammonia) was used in a NON RENEWABLE way, it would INEVITABLY cause deadly environmental problems even if it did not contain a single atom of carbon.

It's NOT the CARBON. It's the LACK OF RENEWABILITY that's killing us.

What we desperately need to do is eject all of the religion out of schools (where it has no business) and replace it with courses on environmental management, evolution, biology etc.

Why so many inefficient steps if energy can be directly stored from sun into batteries? The best research bet right now would be increasing the energy density and charging cicles of batteries, as well as reducing it's cobalt content for environmental reasons.
