NH3 as the H2 Carrier and breakthrough Method of NH3 decomposition Author: David Judbarovski, systems engineering, principle inventor, retired Abstract Here I suppose to offer the method of the hydrogen extraction from ammonia by its oxidation partly,   at moderate temperatures. Such hydrogen can be served as a clean and cheap   and non- poisoning fuel for H2-air Fuel Cells for high energy effective engines’   powering without any harmful exhaust being the water vapor and nitrogen only. At present, decomposition of ammonia needs noble metal catalysts, being very expensive and rare ones, so such hydrogen is very expensive, and it is a big obstacle for large-scale introducing it as a common technology in the world practice. . The problem of substitution the noble metal catalyst by something more cheap and common is a hot engineering problem being now   not solved. (see Bell, T.E., Torrente-Murciano, L.

(A) https://www.statista.com/topics/1728/ocean-shipping/ Ocean Shipping - Statistics & Facts Published by Statista Research Department , Mar 18, 2020 The international seaborne trade volume has been on an increasing trend in recent years. However, in 2018, the maritime trade volume grew only by 2.7 percent on the previous year, down from the 4.1 percent registered in 2017. Further slowdown is expected to occur in 2020, as shipping companies will incur further costs to comply new International Maritime Organization’s sulfur cap regulations . At the same time, the trade and supply chain disruptions caused by the coronavirus (COVID-19) pandemic reverberate across the global economy.

Sea vessel with clean exhaust Author: David Judbarovski, systems engineering, principle inventor Abstract Here ammonia is used   as a fuel for transportation by sea, while for safety of crew, it goes at a safe gap from the sea vessel.  Note: If an accident with  ammonia leakage or even if its burst from its storage to the sea water, the ammonia is turn in ammonia hydroxide solution, widely applied in everyday life, food industry and pharmacy and so on.
