What happened to Ammonia?

[NJH]

As a fuel that is for ICE.

Asking as there have been articles recently about its future use for cargo ships, however it has been around for decades as a potential fuel for cars and trucks but never seemed to have developed very far.

Ammonia has the same fundamental issue as hydrogen: how it is produced industrially.
It is synthesised from nitrogen and hydrogen at very high pressures and temps, using a lot of energy. The hydrogen is, of course, made from natural gas by steam reforming which generates CO2 - more than would be produced by just burning the methane directly.

Agreed, it breaks down as a fuel cycle at that point.

Easier to store however and burn in both compression and spark injection engines, looks like the kit required on the vehicle is not that dissimilar to LPG. NOx in the exhaust though is horribly high so not entirely green, requiring additional systems.

Does look however that shipping could go the Ammonia route whilst urban / semi-urban transport is undoubtably converging towards BEV solutions.

Nah, she was written out of an early draft of the Rocky Horror Picture Show.
