Has to be catalysis that can store co and h2 gasses

Is it really just me, i think the production of hydrogen is completely immoral, why does the manufacturer and others think it is acceptable to destroy the most important liquid on the planet, the very liquid of life, water, what am i not seeing

We couldn't just burn corn food for energy, now we go right to the fertilizer that grows it. This is what a mass extinction looks like.

As I was researching the feasibility of solar islands, I came across ammonia a an efficient option. Glad to see it does seem to be viable. See my blog for additional concepts. thoughtsonclimate.blogspot.com/2023/12/thoughts-concerning-climate-change.html

They should make a biodiesel friendly DPF system.

Only to fill articulated airships.

"...All electricity and heat generated in the stack".... As I know an electrolizer inputs electricity and water and outputs hydrogen and oxygen. How come stacks generate electricity? Out f what is electricity generated in a stack?

Informative ...

Bang on target, the video! Thanks.

That is very informative. I have a doubt. Does the stack heats up by itself or all the heat comes from the steam temperature? Does the stack need to be in a furnace? Is it possible to operate this at 171 degrees Celsius with that stack thermically isolated? Thanks

Hi. For water solid oxide electrolysis. Do I need to input 600oC steam or the electrolyzer heats up with electricity?

👍

This is green washing hydrogen at the moment it takes 50kw of electricity to make 1kg of hydrogen so only 70 percent efficient. The other losses is heat and increase of caustic KOH that might eat away the electrodes . The byproducts are oxygen and heavy water, heavy water is in short supply so there is demand for it in medicine. With the 200MW electrolyser you need a step up transformer the best source of 24/7 energy is nuclear power plants. For Scientists aim and goal is to lower 50kw to 40kw it is possible.

Very informative video

This is poetry to my ear! And what a lady. A real treasure to science. And Topsøe.

All hydrogen stocks suck and will continue to suck until electrolyzers are conceived, designed, and built that can produce millions of tons of hydrogen per annum. Right now, this is not even close to possible and there is not one shred of evidence by alkaline cell, PEM, SOEC or any other electrolyzer design that it will be possible in the future. Hydrogen electrolyzers and fuel cells are total nonsense in India and everywhere else, the "Hydrogen stocks" are hopeless losers because none of the electrolyzer companies can deliver industrial-scale capacity. They only offer small-scale electrolysis capacity, so they can't provide anything but small-scale revenue. Small-scale revenue will never eclipse their operating budget, so they cannot show a profit (earnings). Small-scale electrolyzers cannot make enough H2 from water to reduce CO2 output at an industrial scale, so they are irrelevant. Renewable energy is coming on line quickly, but to reduce global warming, one must decarbonize all of the greenhouse gas emitting sectors -- transportation, agriculture, residential & commercial building and industrial sources (primarily concrete, glass, steel and industrial chemicals). That means we must create decarbonized fuels such as green ammonia, whereby we take cheap and abundant renewable energy and split water into cheap hydrogen and oxygen. Then, humanity can remove nitrogen from the air (air is 78% Nitrogen) and, using the Haber Bosch method, combine the green H2 and N to make green ammonia (NH3). Ammonia, as a "liquid carrier of hydrogen fuel," can carry more hydrogen/BTUs by volume at a reasonable temperature and pressure than gaseous or liquid hydrogen. Large-scale electrolyzers (no existing electrolyzer manufacturer can provide) would allow green ammonia to fuel and power all greenhouse gas emitting sectors. When electrolyzers are scaled to provide ammonia-scale plants producing four million metric tons of anhydrous ammonia per year, replacing methane feedstock; call me. It is important to realize that to produce one ton of ammonia using today's methane "steam reformation process" conventional ammonia producers for nitrogenous fertilizers release 2.84 tons of CO2.

What's SCR technology? Is it a non precious catalyst? Can you just burn rich then a second stage lean to reduce NOx production in the first place?

Ammonia has great potential. However, I doubt using wind and solar to produce it is the best. I suspect Ammonia from Nat Gas would be cheapest, as Carbon Capture becomes more used. Also, geothermal and Hydro and Nuclear are better sources of electricity to make Ammonia, than wind and solar. Wind and solar would require a 500 fold increase in mining for all the minerals. And many minerals are rare earths. There is no logic to the massive use of wind and solar.

If we didn't have the DPF systems, every restaurant, home, and business in America would be able to send their used oils into the fuel tank of a semi truck. We would have $2 a gallon biodiesel, readily available, made by smaller companies, making a more decentralized source of energy production not subject to wild swings in fuel costs. Regular biodiesel is easy to make and almost any type of waste oil can be used to power a semi truck without a DPF system, LOWER EMISSIONS TOO!!!

wish the camera could focus on the graphs more than the guy walking back and forth.

Hello Topsoe, i may need your contact email, i want to send a project proposal to be reviewed and studied about a steel foundry factory in Indonesia. My superior and EPC company already chose Topsoe company as they project licensor. Indonesian Topsoe representative couldnt provide such that services, thats why my superior priority is to get contact directly to Denmark HQ

Just curious, what is the benefit of ammonia over other bio-fuels like methanol, for example, that is liquid at ambient conditions, similar to produce and more energy dense, as well ?

Very informative!

Are you ready to commercialize it on gigawatt scale ?

100% efficiency...thats really amazing.....complete conversion of electricity to H2....fantastic HT

Awesome presentation! Drop in renewable fuels are the future!

Surely there must be a more energy dense liquid hydrogen carrier!? Why not just use synthetic E-kerosene?

A very informative presentation about metallurgy!

An obvious first step is to retrofit bulk ammonia tankers to dual fuel use, burning ammonia on the way out, and bunker fuel on the back-haul.

Green Ammonia as fertilizer too

Europe has GHG targets but like my place in India too can a small part of it can it be applicable

The damp locust fittingly suggest because caterpillar intraperitonally join out a awake wedge. adhesive, skillful professor

pity that anhydrous ammonia is highly toxic and corrosive.............imagine that leaking inside the hold of the ship...........even just a wiff of it is a powerful burning,corrosive sensation inside the airways. Its far preferable over something a dangerous and explosive as hydrogen gas, but it still has significant challenges.

very useful for my project. Thank you

Are there any companies in America currently focusing on research and development on this energy technology

Very promising direction with the core technology SOEC from topsoe, where I used to work. All the best!

Are there any working green ammonia ships?

Very informative

Thank for publishing this video... truly informative..

special thamks for the air craft Admiral Kuznezov Russian navy fleet to keep clean our planet in good order. pls see smoke the fex haust pipe of this ship.
