Can ammonia be a way to store energy?

Question

Can ammonia be a way to store energy?

Answer 1

Ammonia enthalpy is around 21000 kj/kg in the contained hydrogen...

So ammonia  can be used as a great energy storage

but it's expensive.

Infact the global efficiency

wind... energy(electric energy)  ---->   hydrogen  ----> ammonia ----> hydrogen ---- electric energy        is only about 15-25%.

Ammonia toxicity problem is solved with the utilization of some salts that store.. a large amount of ammonia(an example is Mg(NH3)6Cl2, salt volume=liquid ammonia volume) without releasing ammonia into the air at room conditions...

Answer 2

It would work-ammonia is toxic and very hard to manage but it would be a wayto store energy.

Answer 3

Ammonia is corrosive. But it can be split into hydrogen and nitrogen. We would use a catalyst to split H from N, separate the two elements, then use the H as fuel in a Ballard cell.

The nitrogen is heavier in the ammonia than carbon is in methane, but ammonia is still energetic for its weight and we do not have to release the carbon that methane has. The purpose of using nitrogen is to allow  hydrogen to be compressed into a smaller cylinder with less pressure than needed for either hydrogen or methane.
