Abstract

Here I consider a cars’ design allows 1000 km mileage by H2-air fuel cell fed from small bottle with gaseous hydrogen at normal conditions outside the bottle, and at T and P designed for FC inside the bottle, in quantity of some seconds of the car’s running, when in its turn, the bottle intake is coming from another tiny bottle (*), served for its ammonia electro-thermal decomposition and placed being protected on outer wall of the car and fed through a check valve opened electrically in pulse regime with time controlled delay, by liquid ammonia stored on-board of the car at not extreme conditions, e.g. it is liquid at about 10.0 atm., if room temperature.

And all those can be ordinary approach to safety problem, because it well known, that hydrogen and ammonia in tiny quantity, even if occasionally ignited in large air environment are practically hazard free, and any small leakage of ammonia stored in operative quantity in a car, it can be immediately detected by its strong pungent, but not lethal odor, and by sensor and alarm, and they allow immediately to retire to a safe distance.  

My own particular innovation is including above mentioned, as its key part, but additionally I suppose the following chain of ammonia technologies and devices for them.

They are:  

green ammonia production from air and water very cheaply by extremely cheap energy of a special wind power plant deployed near a refueling station must be near, but outside towns. It is a long story, but was earlier disclosed and evaluated (e.g. see (1) Novel way of Nitrogen Cost Reduction for Ammonia Industry. https://judbarovski.blogspot.com/2019/09/  (2) AIChE 2019, reports submitted – Microwaves-Thermal Water Splitting. http://judbarovski.blogspot.com/2019/04/ (3) Wind turbine to stop the global warming. Real way. https://judbarovski.blogspot.com/2019/12/  );

reliable safe refueling station, and method and devices for safe refueling up to related details of car’s design  (see they below),

,

They totally can be breakthrough innovation opening the door for practical realization hydrogen economics and hydrogen energy for towns and cars aren’t concentrated in small area, and not for large city. .

  

Behind the saloon’s wall there is a locked tight section, and there are three rectangular cylinders (e.g. 80 cm long) one above another with 16 kg liquid ammonia each. It can be enough for 1000 km mileage for ordinary car with H2-air FC of 65% energy efficiency, if an electric mover per each wheel. The cylinder ends can be colored differently. The front end serves for refueling through a check valve. The back end provides the bottle (*) by liquid ammonia, as described in first paragraph.

Note: I can suppose any personal cars to have nothing perspective for not so far future, especially cars fueled in any configuration by hydrogen, in favor to city-cars as electric grid element and to flying vehicles for suburb and country. So hydrogen fueling hazard free can be theoretical consideration only.
