New chemical process could make ammonia a practical car fuel

overThruster (58843) writes "A phys.org article says UK researchers have made a breakthrough that could make ammonia a practical source of hydrogen for fueling cars.

From the article:

"Many catalysts can effectively crack ammonia to release the hydrogen, but the best ones are very expensive precious metals. This new method is different and involves two simultaneous chemical processes rather than using a catalyst, and can achieve the same result at a fraction of the cost."

"Professor Bill David, who led the STFC research team at the ISIS Neutron Source, said "Our approach is as effective as the best current catalysts but the active material, sodium amide, costs pennies to produce. We can produce hydrogen from ammonia 'on demand' effectively and affordably.""

"Ammonia is already one of the most transported bulk chemicals worldwide. It is ammonia that is the feedstock for the fertilisers that enable the production of almost half the world's food. Increasing ammonia production is technologically straightforward and there is no obvious reason why this existing infrastructure cannot be extended so that ammonia not only feeds but powers the planet.""

its too poisonous to use for car fuel (1)

Obscene_CNN (3652201) | about a month ago | (#47326041)

"there is no obvious reason why this existing infrastructure cannot be extended so that ammonia not only feeds but powers the planet." How about ammonia being too poisonous to use as fuel in a car? Exposure to gaseous ammonia can result in lung damage and death. Pure ammonia boils at -33 degrees C and once it is diluted to a safe level it isn't suitable for fuel. Yet this person wants the average idiot to put it in their car?
