Based at Monash University, School of Chemistry, our goal is to find new materials for next generation energy storage challenges, e.g. building better batteries and electrochemical synthesis of ammonia. For latest updates on our work, subscribe to our channel or follow us at twitter @DRMacFarlane @Simonov_A_N Designing lithium batteries for next generation devices invites challenges that conven...
The BIG problem is this takes lots of clean water. Where are you going to find that much clean water and not deplete aquifers?
What about using green hydrogen to 'fix' atmospheric or captured CO2 into methanol in the presence of a catalyst, which is a liquid at r.t. and boils at 65 deg C? In addition to being a good alternative to ammonia as a fuel, methanol is also a useful chemical intermediate as well. See: en.wikipedia.org/wiki/Methanol for more details.
Fantastic outcome & congratulations to all. Two questions... How are you going to spend your Chemistry Nobel winnings? How long before I can buy one for our vineyard?
price?
This appears to be the front-runner in the search for electrolytically produced ammonia on an economically viable scale. They are worth watching very carefully!
So, with the planet's natural fisheries being annihilated by agricultural ammonia runoff, how is proliferation of an already major industrial commodity going to improve the future? And are the inventors not concerned with the entire world being filled with Timothy McVeigh's, armed not with low-explosive fertilizer but with high explosives nearly free for the asking? Alfred Nobel claimed to have a nervous breakdown for his defacto invention of world industrial warfare. Has something about that changed we should know about?
Can this be run in backward ? meaning if I give ammonia, can I get back Nitrogen and Electricity back ? Such that it can be used as an storage of electrical energy, just like an battery.🔋
Good question! Yes, if you burn or use catalytic decomposition you get nitrogen, water and air out. You need to be a little careful because if it is not setup right you get NOx which is also bad for greenhouse and acid rain. However, ammonia is often used to reduce NOx in diesel engines so there is a lot of industry knowledge in how to minimize NOx already. There are people developing ammonia fuel cells. There are engine builders making flex-fuel marine engines that can run on ammonia, cng, diesel, etc. Japan is modifying coal power plants to run on a coal-ammonia mix. I believe, gas power plants can run on straight ammonia. Cosworth the racecar engine builder has a turbine generator range extender that can run on flex-fuels (really neat, 50kg unit, 1 moving part, supports a sports car with 4 motors and 1100 wheel hp).
Are you giving Water along with Nitrogen as an Input ? Or, Hydrogen has to be given as an input insted of water ?
How much energy is consumed to produce 1Kg of Ammonia ?
Usually, companies discuss a 70% efficiency in creating pure liquid ammonia.
Wow. It's big
CO2 is good for the planet. It's what plants crave. There is no climate crisis.
Decarbonising implies burning the atmospheric oxygen thus depleating the vital gas supporting the animal life. When CO2 is produced it is converted by the plant life to cellulose and oxygen, it is not the case if you burn hydrogen for example. This obcession is suicidal and should be stopped, I understand that sensless speculators do not care about the wellbeing of people and their futur and prosperity. Keep spinning the slogan and keep sinking us in the abis. One does need to invoke the end of the world to justify developping new ideas.
where is the full paper!!
This sound interesting. Unfortunately link to the paper is cut off, it terminates halfway through and adds ...
the full link ends with s41586-019-1260-x Not sure if I can post the link here
I've never so much gobbledygook in my life.!
So once this is at production scale, roughly how much ammonia will be produced per kWh? What kind of power draw and ammonia output would you be looking at for one of the "thick iPad" units, and how much water will it consume? 🤔
can anyone tell me where the component materials come from (H2 and N) ?
h2 from water and n i guess from gasoline tank
Water and atmospheric nitrogen. 🤓
@@serversurfer6169 i was afraid you were going to say that ... how much energy in MWh is required to produce 1 metric ton of NH3 is the million dollars question?
@@oriocoookie Why were you afraid of that? I didn’t see anything about how much power was required; we’re probably expected to know the theoretical yield. 😜 They seemed more focused on efficiency as a function of electrode area. Their latest results put them at ~150 nanomoles per square centimeter per second , so a square meter of electrode would produce nearly a mole per day. They said something the size of “a thick iPad” could supply an entire farm, so it’s unlikely to require more than a couple kilowatts, I’d guess. Apparently it also handles intermittency fairly gracefully. 🤷♂️
@@serversurfer6169 to be green it requires a green energy source etc etc ... the issue is the cost per kg of green NH3 produced vs that of black NH3. Being a low cost green H2 producer i have a pretty good idea how much energy plus capex plus opex is required to produce green NH3. In any case I am keen on anything that would improve the overall cost per kg NH3 and quite willing to hear from any one. Not on youtube though.
There you go! The most important chemical to human existence, converted from If the (TFMS) and Li hold up. Run the gas ultra pure at different temperatures and see how many moles of ammonia can be produced without reductive degradation of the electrolyte or poisoning . I wonder how the thermal management is. If it scales and If it can run 10,000 hours and still have a 90% F.e , you may have a real game changer. Ammonia can be used to power the new ( fuel agnostic) Flameless Linear Generators like Mainspring Energy's and GE/Hylion's Karno. These could be placed near wind, solar, nuclear plants to form the H2, and then collect the electrons on site. The ammonia could be piped as gas or liquid much easier than H2, a central ammonia reservoir. NH3 can be efficiently reformed to back to hydrogen near fueling locations.. There is also electrochemical cells that change CO2 & NH3 to urea. If powered by carbonless energy, this would remove CO2 from the air, and create fertilizer for plants. In tun those plants would absorb even more CO2. I can also see a device like this as essential to Mars colony.. Mars has 3% N2 and 95% CO2, so there is no Nitrogen for plants, this could be used with a hydrogen fuel cell to create enough ammonia to grow plants
What is the energy effechantys of ammonia electrolysis?
Quite an achievement!
