Jens Nørskov: Generation of Ammonia Using Solar Energy | GCEP Symposium - October 18, 2017

[@sivabalankaniapan6275]

This is simply amazing.

[@danyun717]

This will be revolutionary as a carrier for the Hydrogen economy

really really good for my exercise

Dear Professor and my friends here, Good day to you all. At 17:05, professor said that we don't have that. That's a challenge! I don't understand what and why?

[@dan2304]

Will be necessary for ammonia for fertilizer. But for energy; how much of the original energy used to make the ammonia is left in the ammonia? Very little, maybe some 10 times the energy to make ammonia than is in the ammonia. Batteries are all ready over 90% efficient.

Does anyknow know what the asterisks represent on the chemical reactions? Min: 11:54 Thanks!

[@johanv4668]

Chemical synthesis reaction is on top of that page. this is what going in and result is what is comming out.( in 1 step ) but these kind of reaction don't go in 1 step. the under laying steps are here explained. but we don't know all these steps exactly. mostly is theoretical. if we better understand how reactions are steped. we can also better predict what kind of catalysator is needed.

[@petevenuti7355]

I believe the * represents electrons, but keep in mind these elements want to be diatomic so the monoatomic are intermediate and temporary.

[@buggi666]

In chemistry this is in layman terms like being "excited"

[@martinr7728]

the * refers to a site on the catalyst

[@kanti12us]

where are you getting 700K heat?

[@shawnnoyes4620]

Gen IV nuclear reactor

[@oktogen1476]

Fossil fuels

Nitruction? (At 7:18) the natural enzyme? HELP!

[@jessehorstman]

[@AKK105]

Do you mean nitrification?

[@NSBarnett]

@@AKK105 I'm asking what the man said. It sounded like nitruction, but I think there is no such term. He's clearly a non-native English speaker, so maybe it's a word from his language (Danish, possibly). Or maybe it's a jargon word for Nitrogen-reduction, Nitrogeduction, Nitroduction, Nitruction, you see? Maybe that's it.

[@glike2]

Why not build a high pressure plant at an equal pressure depth under water?

[@pearsonbrown6740]

Because you need to match that pressure to force it into that environment.

[@travismoore7849]

Why can't you just react urea over calcium oxide for ammonia?

[@Noah-be5rj]

Where do you get the urea

[@travismoore7849]

@@Noah-be5rj Ebay, amazon, fertilizer stores maybe even tractor supply and so on. Urea is made from methane at many fertilizers plants. Heck it may be messy but you can get it from piss if your really hard up.

[@Noah-be5rj]

@@travismoore7849 It doesn't make sense to use industrially produced urea since it's produced using ammonia in the first place. You could extract small amounts from urine but it won't be enough to produce the amount of fertilizer we need. The only source of nitrogen which is "free" and didn't come from the haber Bosch/ biological reduction in the first place would be from the air or minerals. I don't think mining nitrogen containing minerals is a good way to get ammonia though...

[@wilfriedschuler3796]

@@Noah-be5rj Of coure from CO2 and NH3. And the NH3 means Haber Bosch. So the idea is silly.

[@khronyk6139]

if more engineers would be inspired and work on the side of their jobs, those projects, we wouldn't have to wait so long for improvements. in any other field, if you have an idea, everyone will tell you to spend time on it when you can.... scientists.... no way. They are busy day dreaming.

[@seaplaneguy1]

Yes, this the the direction renewables should take. My engine at 60-75% efficiency would then use the fuel instead of needing a heavy battery. This can work in airplanes too, whereas batteries are too heavy by 10-20 times.

[@Mickeycuatropatas]

Good work! Now the race to get AI to solve the problem and maybe quantum mechanics. What about ammonia synthesis via the 2-step Al2O3/AlN thermochemical cycle? Skip the catalysts altogether!

[@johanv4668]

you need very high temperature for that reaction and that is a big cost of energy. so a bad thing. you need what this guy is telling you some thing cheap and simple. and you do this with a catalist.

[@shantahsieh432]

You need to make some changes. Check Avasva Solutions if you want to make it right.

[@111chicane]

Did you build solar panels following their guide? Or wind turbines? I'll tell you what, Avasva Solutions is a scam! One of many! Oh, wait! You already know that, you're with Avasva!

[@AKK105]

What is avasva solutions as I can't find it in internet?
