Hydrogen Talk: Clean Ammonia in the Future Energy System

[@duncanlawson4002]

Two Canadian companies making ammonia from a single container sized plant. They only need air and water , process runs at 45 centigrade, and operates at standard air pressure , masssively lowering the cost of making ammonia. Fuel Positive will deliver its first unit to a Canadian farm this quarter 2024 .

Why would you take renewables and make hydrogen then take more renewables to make ammonia then use more energy/fuel via shipping to take it to destination country only to burn it in electricity generators to create power, When all you have to do is use renewables directly in country of manufacturing,, ammonia is for transport / trucks /boats /trains/cars but only once the NOX emissions have been sorted Renewables are for electricity manufacturing , Absolutely .

One need 10KWh/ kg process energy for ammonia. And if one burns it, the result is a lousy 5,2 KWh/kg. Can anybody tell me where the benefit is hidden?

[@Greenammonianews]

I have been getting up to speed. You raise a good point. The efficiency number I often see is about 70%, Put in 10KWH and get out 7KWH of chemical energy stored in ammonia bonds (liquid). Producing hydrogen is often quoted around 75% efficiency but you invest 30% of the remaining energy in chilling it to a liquid. Some researchers hope to get the initial efficiency up to 95% with better catalysts, selective membranes, etc. The chilling will always be an issue.

@@Greenammonianews Ammonia ist consisting of 23,5 % hydrogen only. Using ammonia as verhicle ist stupid. It means you are not transporting hydrogen but nitrogen. The cracking of ammonia is energy consuming, leads to material losses and delivers not a pure hydrogen but a spoiled quality which needs further cleaning. Absolutely lunatic idiots at work.

In theory, the benefit is if you've got essentially free solar energy in Australia you can make ammonia and ship it to Japan. For use in transportation fuels, you've got to consider what your alternatives are for jets and ships. In those cases you can't just use batteries to store the power until you need it - the batteries are too heavy (for jets) or too expensive (for ships). For ships, the main competitor would be to use methanol as a fuel instead of ammonia. What is the efficiency of creating methanol from C02 and hydrogen?

[@wilfriedschuler3796]

@@Greenammonianews It is clear. You have no technical background. The enthalpie for burning ammonia is 5,2 KWh per kg. That´s all. As I said. One needs 10 KWh and gets 5,2 KWh. And who will deliver the missing 4,8 KWh? The easter bunny?

[@wilfriedschuler3796]

@@richdobbs6595 It is clear. You are another one of the guys talking about music like a deef. Ammonia contains 17,6 % hydrogen only. Nitrogen is uselees, no energy. So you are handling and manipulating 83% of a useless stuff, importing it to Japan, process it again and blow it in the air? Are you sane? Beside the fact that you need close to 1 KWh/kg to process all this. And where do you get this energy to be wasted in Japan? From imported LNG. Free solar energy is such an idiot phrase. You need solar paneels by the square mile. Do you get them free? They are all made in China and a hell of coal is burned for them.

For 3 years, the hydrogen stocks worldwide have only known the way down. Some of the largest hydrogen companies have lost up to 80% in value and there is no end in sight. A success story looks different. The big companies have never made a profit and according to them that will not change anytime soon. In other words, hydrogen is the big loser on the stock market and the heads of the hydrogen companies don't care.
