Ammonia

Ammonia (NH₃) is a form of nitrogen. The vast majority of ammonia is used for fertilizer. Ammonia production requires energy. Currently this is mainly done with fossil fuels.

Can it be used as energy storage?

Suppose we find another (greener) scaleable way to produce ammonia... Then could it be used in vehicles as the "fuel of the future"? Because apparently it's easier to work with than hydrogen gas. (...)( Hydrogen gas can hold more energy by mass, but it's also the lightest of all gases. Ammonia can hold more energy by volume. )

Questions unanswered:

What about the NOx emissions of burning ammonia? Wouldn't those be far higher than the NOx emissions of burning gasoline or hydrogen? Could that produce a greenhouse effect even worse than gasoline? "More research is needed" but honestly this shouldn't be a hard question to answer. Join the discussion.
