Green ammonia as a marine fuel

Learn about the benefits of Ammonfuel, the future fuel for the maritime sector. Ammonfuel is based on the production of green ammonia which is a clean fuel that does not pollute the air. Read more about Ammonfuel from the report "Green ammonia as a marine fuel": info.topsoe.co...

Green Ammonia as fertilizer too

[@user-jc2we4sn1i]

Only to fill articulated airships.

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?

[@Alessandro-1977]

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 ?

[@BillSmith-su4jt]

Ammonia does not take food away from millions of people who are starving each year on this planet. And if all energy was supplies by methanol, there would be no food for anyone to eat.

[@Alessandro-1977]

If it were *ethanol* I certainly agree with it. But to produce *methanol* through biomass gasification and an external source of energy, hydrogen and/or heat it needs very little biomass. Methanol is even an excellent fuel for IC engines and an interesting one for fuel cells, as well. Swedish university of Lund KZbin channel has 2 interesting videos about that kzbin.info/www/bejne/oqe1qYNpnNOqeKs kzbin.info/www/bejne/nWKpdWyvoriEm7c

Ammonia (NH3) can be "cracked" to produce N2, and power a fuel cell with hydrogen, emitting H20. No carbon reacted, no carbon in the fuel, no CO2 increase over the intake air. Alternately you can combust it but this produces nitrous oxides which requires either multi-stage combustion (to prevent) or catalytic conversion (to treat). Assuming the nitrous oxides can be reduced and removed, the exhaust outputs are N2 and H2O In comparison methanol will emit CO2 during combustion

[@wazza33racer]

@@anonymousAJ however, if the Methanol is made from captured, recycled CO2 (from fossil combustion) or even better, the surplus CO2 from Biogas production.....it would be half or in the case of biogas, completely zero carbon emission.

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.

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.

[@BillSmith-su4jt]

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.

[@Alessandro-1977]

Indeed, that' s why a biomass gasification approach with methanol does make more sense. The biomass input is minimal and the energy need can be reduced to perhaps 2-2.5 kWh per liter (gasoline equivalent) vs more than 10 kWh/l for ammonia (at the very least...)

[@wazza33racer]

making Ammonia from natural gas? thats VERY NAUGHTY! straight to the glulag camp for you! there the WEF commissars will re-educate you!

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

Are there any working green ammonia ships?

[@ruslanzakirov3238]

I never heard about any working green ammonia ship. Who is going to order these type of vessels? First, you need to develop infrastructure, built bunkering vessels. Ask how many ammonia carrier ships are built by now? There are mor equestions than answers.

[@jordansage9655]

@@ruslanzakirov3238 um a little company called Maersk will be.

[@ruslanzakirov3238]

@@jordansage9655 I worked for Basic Design team and Engineering Management department at the second world's biggest shipyard Samsung Heavy Industries, at DSME, HHI in Korea, at Keppel FELS and PPL shipyard in Singapore, in Russian shipyards. Green ammonia ship? Is that built by Japanese shipyard for ammonia transportation? Will be? Let's see how they will put together the econimics of shipbuilding and ship management. For now, the economics do not work for this type of fuel.

[@jandersen6802]

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

[@SeaworthyShippingServices]

👍

[@wazza33racer]

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.

[@FelonyVideos]

AA is already used all over the place. Farmers use it every spring. Almost no accidents.

[@wazza33racer]

@@FelonyVideos for sure, farmers are out in the open, in paddocks and not inside a steel structure where ammonia gas can congregate. With the right precautions, like gas detectors, and sealed bulkheads to contain any leaks it would be practical and still 1000% better than hydrogen.
